Blackberry - How to get Field Labels from PIMItem - blackberry

How can we get Field Labels from PIMItem. The following code is with PIMList
String label = pimList.getAttributeLabel(
blackBerryContact.getAttributes(Contact.TEL, i));
But i have PIMItem. There is a method PIMItem.getPIMList() which returns null for me in the code below. THE API at http://www.blackberry.com/developers/docs/5.0.0api/index.html says "getPIMList()
Gets the PIMList associated with this item." Below is sample code that i am trying to achive -
// Load the address Book and allow the user to select a contact
BlackBerryContactList contactList = (BlackBerryContactList)
PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_ONLY);
PIMItem userSelectedContact = contactList.choose();
// Now get the Field labels for contact numbers for userSelectedContact

class Scr extends MainScreen {
Scr() {
}
protected void makeMenu(Menu menu, int instance) {
super.makeMenu(menu, instance);
menu.add(new MenuItem("add label", 1, 1){public void run() {
try {
BlackBerryContactList contactList =
(BlackBerryContactList) PIM.getInstance().openPIMList(
PIM.CONTACT_LIST, PIM.READ_ONLY);
BlackBerryContact contact =
(BlackBerryContact) contactList.choose();
add(new LabelField(getContactInfo(contact)));
} catch (PIMException e) {
e.printStackTrace();
}
}});
}
String getContactInfo(BlackBerryContact c) {
StringBuffer result = new StringBuffer();
result.append("Name: ");
result.append(c.getStringArray(
BlackBerryContact.NAME, 0)[BlackBerryContact.NAME_GIVEN]);
result.append(" ");
result.append(c.getStringArray(
BlackBerryContact.NAME, 0)[BlackBerryContact.NAME_FAMILY]);
result.append("Email: ");
result.append("\n");
result.append(c.getString(
BlackBerryContact.EMAIL, BlackBerryContact.ATTR_NONE));
return result.toString();
}
}

Thanks Max for the response. The returning NULL issue was problem with my code which i have rectified. I was also able to get Labels for Fields, but the loop retrieves only fields that the Contact has on his card.
I am looking to get all the 8 labels that Contact.TEL has -
Int maxAllowed = contactList.maxValues(Contact.TEL); // Gives me 8
All the 8 Labels might not be in use in for a user, For e.g a user might have WORK, WORK2, HOME, HOME2 and MOBILE. Others FAX, PAGER and OTHER might not be filled i want to get all the allowed labels and update a given number for the one that is empty.
How can we check and update the following
Contact.ATTR_PAGER, Contact.ATTR_FAX, Contact.ATTR_OTHER
Please let me know if the explanation is not clear, or some more details are required.
BlackBerryContactList contactList = (BlackBerryContactList)
PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_WRITE);
PIMItem pimItem = contactList.choose();
BlackBerryContact blackBerryContact = (BlackBerryContact)pimItem;
PIMList pimList = blackBerryContact.getPIMList();
// To get Labels
int phoneCount = blackBerryContact.countValues(BlackBerryContact.TEL);
String[] phoneNumbers = new String[phoneCount];
String[] labels = new String[phoneCount];
for (int i = 0; i > phoneCount; i++) {
String phoneNumber = blackBerryContact.getString(Contact.TEL, i);
String label = pimList.getAttributeLabel(
blackBerryContact.getAttributes(Contact.TEL, i));
//Add the number and label to the array.
phoneNumbers[i] = phoneNumber;
labels[i] = label + ":" + phoneNumber;
}

Xamarin Android, get contact mobile number by using CursorLoader with selection and selection args

I'm trying to get contact details of a contact that the user picks from the contacts list in Android using Intent as the following code:
Intent Intent = new Intent(Intent.ActionPick, ContactsContract.Contacts.ContentUri);
Intent.SetType(ContactsContract.Contacts.ContentType);
StartActivityForResult(Intent, 3);
Now on the Intent results I run the following code to get specific contact information:
public override void OnActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == 3 && resultCode == -1 && data != null) //result code -1 means OK 0 Means cancelled Result.Ok
{
var ContactData = data.Data;
string ID = "";
string name = "";
string address = "";
byte[] picture = new byte[0];
List<string> numbers = new List<string>();
List<string> emails = new List<string>();
string mobile = "";
string email = "";
string selectionString = "id = ?";
string[] columnsNames = new string[] {
ContactsContract.Contacts.InterfaceConsts.Id,
ContactsContract.Contacts.InterfaceConsts.DisplayName,
ContactsContract.Contacts.InterfaceConsts.PhotoUri
};
var loader = new CursorLoader(Statics.mainActivity, ContactData, null, null, null, null);
var cursor = (ICursor)loader.LoadInBackground();
if (cursor.MoveToFirst())
{
ID = cursor.GetString(cursor.GetColumnIndex(columnsNames[0]));
name = cursor.GetString(cursor.GetColumnIndex(columnsNames[1]));
picture = cursor.GetBlob(cursor.GetColumnIndex(columnsNames[2]));
}
//Store Contact ID
string[] selectionStringArgs = new string[] { ID };
//Phone Numbers
string[] columnsNames2 = new string[] {
ContactsContract.CommonDataKinds.Phone.Number
};
var loader2 = new CursorLoader(Statics.mainActivity, ContactsContract.CommonDataKinds.Phone.ContentUri, columnsNames2, selectionString, selectionStringArgs, null);
var cursor2 = (ICursor)loader2.LoadInBackground();
while (cursor2.MoveToNext())
{
numbers.Add(cursor2.GetString(cursor2.GetColumnIndex(columnsNames2[0])));
}
//Email Address
string[] columnsNames3 = new string[] {
ContactsContract.CommonDataKinds.Email.Address
};
var loader3 = new CursorLoader(Statics.mainActivity, ContactsContract.CommonDataKinds.Email.ContentUri, columnsNames3, selectionString, selectionStringArgs, null);
var cursor3 = (ICursor)loader3.LoadInBackground();
while (cursor3.MoveToNext())
{
emails.Add(cursor3.GetString(cursor3.GetColumnIndex(columnsNames3[0])));
}
int TempRecepitntID = 0;
EmployeesViewModel tempRecipent = new EmployeesViewModel();
TempRecepitntID = Statics.mainActivity.currentViewModel.SelectedChat.ReceiverEmployee;
foreach (EmployeesViewModel evm in Statics.mainActivity.currentViewModel.Employees)
{
if (evm.ID == TempRecepitntID)
tempRecipent = evm;
}
new Android.Support.V7.App.AlertDialog.Builder(Statics.mainActivity)
.SetPositiveButton("Yes", (sender1, args) =>
{
Statics.mainActivity.currentViewModel.AddMessage(picture, tempRecipent, Statics.mainActivity.currentViewModel.SelectedChat.ID, "contact", 0, "", name, numbers[0], mobile, email, address);
})
.SetNegativeButton("No", (sender1, args) =>
{
// cancel
})
.SetMessage("Are you shure you want to send?")
.SetTitle("System Message")
.Show();
}
}
The problem is I want to retrieve only the information of the contact that the user selected but what I get is all other contacts data is retrieved so I tried to use the selection and selectionargs parameters of CursorLoader by setting string selectionString = "id = ?"; and selectionArgs to string[] selectionStringArgs = new string[] { ID }; the ID value is retrieved from the following code :
if (cursor.MoveToFirst())
{
ID = cursor.GetString(cursor.GetColumnIndex(columnsNames[0]));
name = cursor.GetString(cursor.GetColumnIndex(columnsNames[1]));
picture = cursor.GetBlob(cursor.GetColumnIndex(columnsNames[2]));
}
//Store Contact ID
string[] selectionStringArgs = new string[] { ID };
//Phone Numbers
string[] columnsNames2 = new string[] {
ContactsContract.CommonDataKinds.Phone.Number
};
But now it returns 0 results, I couldn't find anything on the internet that applies to Xamarin android, Please help.
Thanks,
Finally I found the solution, I used the following string in the selection parameter of the cursorloader method:
string selectionString = ContactsContract.CommonDataKinds.Phone.InterfaceConsts.ContactId + "=" + ID;
and now only the selected contact numbers are retrieved.
I hope this will help someone else.
In additional information of #TMSL, I add the code afer this bloque
if (cursor.MoveToFirst())
{
ID = cursor.GetString(cursor.GetColumnIndex(columnsNames[0]));
name = cursor.GetString(cursor.GetColumnIndex(columnsNames[1]));
picture = cursor.GetBlob(cursor.GetColumnIndex(columnsNames[2]));
}
Here
selectionString = ContactsContract.CommonDataKinds.Phone.InterfaceConsts.ContactId + "=" + ID;
Then I changed the parameters used in the definition of variable Loader2, converting selectionStringArgs in null.
var loader2 = new CursorLoader(this.Activity, ContactsContract.CommonDataKinds.Phone.ContentUri, columnsNames2, selectionString, null,null);
var cursor2 = (ICursor)loader2.LoadInBackground();
I found this documentation from xamarin guides
Uri – The fully qualified name of the ContentProvider.
Projection – Specification of which columns to select for the cursor.
Selection – Similar to a SQL WHERE clause.
SelectionArgs – Parameters to be substituted in the Selection.
SortOrder – Columns to sort by.
So, the variable selectionStringArgs used in the code from #TMSAL cannot use a value like "contact_id = 2700", because the parameter of CursorLoader SelectionArgs is not a filter but not "Parameters to be substituted in the Selection"
I hope this will help someone else too.

Android; SQLite database Cursor is null. It should not be. I don't know why it is

I had a method which fetched records from an sqlite database but after a while i changed it a little and made a secondary method for fetching specific records with user entered information.
I don't know why but my original method is returning null now.
CardDbAdapter:
public CarddbAdapter open2() throws SQLException {
String myPath = DB_PATH + DB_NAME;
myDatabaseR = SQLiteDatabase.openDatabase(myPath, null,
SQLiteDatabase.OPEN_READONLY);
myDatabaseW = SQLiteDatabase.openDatabase(myPath, null,
SQLiteDatabase.OPEN_READWRITE);
return this;
}
public void MyDatabaseClose() {
myDatabaseW.close();
myDatabaseR.close();
}
public ArrayList<String> getAllCardNames() {
ArrayList<String> returnedAllCardNames;
ArrayList<String> NoResults;
ArrayList<String> NoResults2;
NoResults = new ArrayList<String>();
NoResults.add("cursor is null");
NoResults2 = new ArrayList<String>();
NoResults2.add("No similar cards found.");
returnedAllCardNames = new ArrayList<String>();
/*String sqlquery_cardNames = "SELECT " + KEY_CARDNAME
+ " FROM cards WHERE card_name like '%" + passedName
+ "%' ORDER BY card_name ASC";*/
//String sqlquery_cardNames;
String sqlquery_cardNames = "SELECT DISTINCT card_name FROM cards";
Cursor c_cardNames;
c_cardNames = myDatabaseW.rawQuery(sqlquery_cardNames, null);
c_cardNames.moveToFirst();
if (c_cardNames != null) {
do {
if (c_cardNames.getCount() > 0) {
String returnedName = c_cardNames.getString(c_cardNames
.getColumnIndex(KEY_CARDNAME));
returnedAllCardNames.add(returnedName);
} else {
return NoResults2;
}
} while (c_cardNames.moveToNext());
}
return NoResults;
}
How i am using it:
CarddbAdapter yugiohDB = new CarddbAdapter(this);
yugiohDB.open2();
search_results = (ListView) findViewById(R.id.lvSearchResults);
search_results.setOnItemClickListener(this);
ArrayList<String> returnedCards_list1 = new ArrayList<String>();
returnedCards_list1.addAll(yugiohDB.getAllCardNames());
listAdapter = new ArrayAdapter<String>(SearchMode_Simple.this,
android.R.layout.simple_list_item_1, returnedCards_list1);
search_results.setAdapter(listAdapter);
yugiohDB.MyDatabaseClose();
Any help would be appreciated.
If you would like to see what this is actually supposed to do then download my app called Yugioh Library + Tools. Click the Search Library button from the main menu and then the button Simple Search. It should be displaying a list of cards from the database.
The reason i was changing it is because i'm setting up Spinners so users can choose different trading card sets to choose some which would then list all the cards from that specific set.
Fixed. I forgot to return the string array "returnedAllCardNames" which was holding the names of all process card records after the do while loop.

Blackberry - Clickable BitmapField With Different ID's

i'm creating one application in which i get gift images with id's from web server through JSON. When i click on any gift image, it goes on next page where it shows all information of that image (get image information with its id from web server through JSON).
Problem is: When i click on any gift image on page to see its relevant information, it gets the last gift image id every time, i want when i click on any image, it gets the specific image id which i click. How it is possible??
Screenshot of the page is : http://ugo.offroadstudios.com/gifts.png
Here is sample code:
public class Gifts extends MainScreen {
String giftsid;
BitmapField giftimg;
public Gifts(){
setTitle("Gift Store");
creategifts();
}
public void creategifts()
{
//Link URL
String strURL = "http://ugo.offroadstudios.com/api/frndgift/?loginusername=adil;deviceside=true";
webConnection wb = new webConnection();
String res = wb.getJson(strURL);
try {
JSONObject object = new JSONObject(res);
if(object.getString("status") == "error")
{
Dialog.alert("Invalid "+object.getString("status"));
}
else
{
int totalgifts;
totalgifts = object.getInt("totalgifts");
Bitmap listThumb;
JSONArray imagearr;
JSONArray giftsidarr;
String imgname;
Bitmap bmpResized;
for(int i=0; i < totalgifts; i++){
imagearr = object.getJSONArray("gifts_image");
imgname = imagearr.getString(i);
giftsidarr = object.getJSONArray("gifts_id");
giftsid = giftsidarr.getString(i);
listThumb = getImage.getImageFromUrl("http://ugo.offroadstudios.com/wp-content/plugins/bp-gifts-rebirth/includes/images/"+imgname+";deviceside=true");
bmpResized = GPATools.ResizeTransparentBitmap(listThumb, 80, 80,
Bitmap.FILTER_LANCZOS, Bitmap.SCALE_TO_FIT);
giftimg =new BitmapField(bmpResized,FOCUSABLE)
{
protected boolean navigationClick(int status, int time)
{
Dialog.alert("giftsid "+giftsid);
UiApplication.getUiApplication().pushScreen(new SendGift(giftsid));
return true;
}
};
add(giftimg);
}
}
}
catch (JSONException e) {
System.out.println("EX is "+e);
e.printStackTrace();
}
}
}
You are always getting the gift id of the last gift in the list because you have created your buttons with this code:
giftimg =new BitmapField(bmpResized,FOCUSABLE)
{
protected boolean navigationClick(int status, int time)
{
Dialog.alert("giftsid "+giftsid);
UiApplication.getUiApplication().pushScreen(new SendGift(giftsid));
return true;
}
};
Your navigationClick() method used the giftsid variable, which is a persistent member variable of your class. You assign this variable in your for loop, so the final value it keeps is the last value assigned in the loop (giftsidarr.getString(totalgifts)).
Although you declare the navigationClick() method in a loop where the giftsid is many different values, the navigationClick() method uses the value of giftsid when it is run. The last value.
There's many ways to fix it. You can use a separate constant value in your loop:
final String nextGiftsId = giftsid;
giftimg =new BitmapField(bmpResized,FOCUSABLE)
{
protected boolean navigationClick(int status, int time)
{
Dialog.alert("nextGiftsId= "+nextGiftsId);
UiApplication.getUiApplication().pushScreen(new SendGift(nextGiftsId));
return true;
}
};
Or, as Signare suggested, attach a cookie to each button that identifies its corresponding gift:
giftimg =new BitmapField(bmpResized,FOCUSABLE)
{
protected boolean navigationClick(int status, int time)
{
String giftId = (String)getCookie(); // read gift id from the cookie
Dialog.alert("giftId= "+giftId);
UiApplication.getUiApplication().pushScreen(new SendGift(giftId));
return true;
}
};
giftimg.setCookie(giftsid); // set the cookie after creating the field
Inside your for loop, add the following code -
giftimg[i].setChangeListener(this);
Then -
public void fieldChanged(Field field, int context) {
for(int i=0;i<totalgifts;i++) {
if(field == giftimg[i]) {
// you can trigger your event
}
}
EDIT :-
giftimg[i].setChangeListener(listener);
listener = new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
if ( field instanceof BitmapField ) {
for(int i=0;i<totalgifts;i++) {
if ( field == giftimg[i] ) {
// you can trigger your event
}
}
}
}
};

Limited ListField items are drawn instead of complete list in Blackberry

I am trying to draw a list of all contacts saved in device. Everything is fine but when I select all contacts, I get only those contacts which are drawn on the screen. In other words, list drawing only those contacts which are visible on screen. To get the remaining contacts I have to scroll the list.
Here is my code:

Here ,in drawListRow() , get() method is called only that many times that is number of contacts are visible on the screen. For remaining contact to add, I have to scroll the list.
In drawListRow() method I am adding those contacts into selectedContacts vector and than using those vector to get contact to send a mail. Contacts will be added only when particular list item will be drawn.
So, how I can get all selected contact without scrolling the list?
This is similar to the problem you had in one of your other recent questions. The problem is that drawListRow() is a callback designed to let you draw the rows that need drawing. It's not meant to do anything else, like assembling a list of contacts to email.
The BlackBerry OS tries to be efficient, so it will only ask you to drawListRow() for the rows that are actually visible to the user (on screen). Anything more would be wasteful.
So, if you want to assemble a list of all selected rows, you should do it somewhere else, not in drawListRow().
It looks to me like you can build a list of all currently selected rows by using this code, wherever you want:
public Vector getSelectedContacts() {
selectedContacts.removeAllElements();
for (int i = 0; i < mListData.length; i++) {
Object obj = mListData[i];
if (obj != null) {
BlackBerryContact contact = (BlackBerryContact) mContacts.elementAt(i);
String email = contact.getString(Contact.EMAIL, 0);
int vecIndex = selectedContacts.indexOf(email);
ChecklistData currentRow = (ChecklistData) obj;
if (currentRow.isChecked()) {
if(vecIndex == -1){
selectedContacts.addElement(email);
}
} else {
// this line is probably not actually needed, since we
// call removeAllElements() at the start of this method
selectedContacts.removeElement(email);
}
}
}
return selectedContacts;
}

Backup/Restore net.rim.device.api.util.Persitable object with DesktopManger

The task is to backup/restore Persistable object with BB Desktop Manager or in any other way. The main aim is to keep data between device firmware updates...
I have:
public final class UserList implements Persistable {
//The persistable objects.
private Hashtable fData;
//Initialize the class with empty values.
public UserList() {
fData = new Hashtable();
}
//Initialize the class with the specified values.
public UserList(Hashtable p) {
fData = p;
}
public Hashtable getData() {
return fData;
}}
I also have implemented SyncItem (as found in one of the examples)
public final class UserListSync extends SyncItem {
private static UserList fList;
private static final int FIELDTAG_NAME = 1;
private static final int FIELDTAG_AGE = 2;

The entry poing is following:
public class SyncItemSample extends UiApplication {
private static PersistentObject store;
private static UserList userList;
static {
store = PersistentStore.getPersistentObject(0x3167239af4aa40fL);
}
public static void main(String[] args) {
SyncItemSample app = new SyncItemSample();
app.enterEventDispatcher();
}
public SyncItemSample() {
UserListScreen userListScreen;
//Check to see if the store exists on the BlackBerry.
synchronized (store) {
if (store.getContents() == null) {
//Store does not exist, create it with default values
userList = new UserList();
store.setContents(userList);
store.commit();
} else {
//Store exists, retrieve data from store.
userList = (UserList)store.getContents();
}
}
//Create and push the UserListScreen.
userListScreen = new UserListScreen(userList);
pushScreen(userListScreen);
}}
And here is an implementation of screen:
public final class UserListScreen extends MainScreen {
Vector fLabels = new Vector();
Vector fValues = new Vector();
VerticalFieldManager leftColumn = new VerticalFieldManager();
VerticalFieldManager rightColumn = new VerticalFieldManager();
UserList fList;
public UserListScreen(UserList list) {
super();
fList = list;
//Create a horizontal field manager to hold the two vertical field
//managers to display the names and ages in two columns.
VerticalFieldManager inputManager = new VerticalFieldManager();
HorizontalFieldManager backGround = new HorizontalFieldManager();
//Array of fields to display the names and ages.
LabelField title = new LabelField("User List",
LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);
setTitle(title);
final TextField fld1 = new TextField(TextField.NO_NEWLINE);
fld1.setLabel("input label");
inputManager.add(fld1);
final TextField fld2 = new TextField(TextField.NO_NEWLINE);
fld2.setLabel("input value");
inputManager.add(fld2);
final ButtonField fld3 = new ButtonField();
fld3.setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
fList.getData().put(fld1.getText().trim(), fld2.getText().trim());
refresh();
}
});
fld3.setLabel("add");
inputManager.add(fld3);
add(inputManager);
//Add the column titles and a blank field to create a space.
LabelField leftTitle = new LabelField("label ");
leftColumn.add(leftTitle);
LabelField rightTitle = new LabelField("value");
rightColumn.add(rightTitle);
refresh();
//Add the two vertical columns to the horizontal field manager.
backGround.add(leftColumn);
backGround.add(rightColumn);
//Add the horizontal field manager to the screen.
add(backGround);
}
private void refresh() {
leftColumn.deleteAll();
rightColumn.deleteAll();
fLabels.removeAllElements();
fValues.removeAllElements();
//Populate and add the name and age fields.
Enumeration e = fList.getData().keys();
while (e.hasMoreElements()) {
String key = (String) e.nextElement();
String value = (String) fList.getData().get(key);
final LabelField tmp1 = new LabelField(key);
final LabelField tmp2 = new LabelField(value);
leftColumn.add(tmp1);
rightColumn.add(tmp2);
fLabels.addElement(tmp1);
fValues.addElement(tmp2);
}
}
public boolean onClose() {
System.exit(0);
return true;
}}
So as you see it should be very easy...
So all of these I run application, add values to Persistent object and they are added correctly, are stored during device resets and so on...
When I run Desktop Manager and make a Backup it seems that UserList is backed-up, as size of backup grows together with adding new data into persistent store.
But when I run "Wipe device" on my BB 9300 (and all data from Persistent store is cleared as it is expected) and then run Restore from just made backup file - nothing is updated in the Application and persistent store is seems to be empty.
In some examples I have found adding alternate entry point "init" but I can't tune eveything like it is described with my EclipsePlugin
Could you advice me how to store data in backup file and the to retrieve the same data from backup and load it back to the application, or how to log any of events with Desktop Manager?
If someone has experienced the same problem you can try to disconnect the device before wiping it. It is strange but it helped :)
