In my handler Messages are received as desired. But even though I have added the proper object sent by message to the adapter, the object is not added to the row. I don't know why it doesn't work
This is a handler that receives a message from another fragment's click event.
redHandler = new Handler(){
#Override
public void handleMessage(#NonNull Message msg) {
item = (PackageModel) msg.obj;
listRowAdapter.add(item);
}
};
and this is fragment's click event
private final class ItemViewClickedListener implements OnItemViewClickedListener {
#Override
public void onItemClicked(Presenter.ViewHolder itemViewHolder, Object item,
RowPresenter.ViewHolder rowViewHolder, Row row) {
if (item instanceof PackageModel){
Log.d("CurrentThreadRed", Thread.currentThread().toString());
Message msg = new Message();
msg.obj = item;
handler.sendMessage(msg);
}
}
}
this is my row
private void setFavoriteRow(){
Log.d("CurrentThread", Thread.currentThread().toString());
AppList appList = new AppList(getContext());
List<PackageModel> list = appList.setPackages();
HeaderItem headerItem = new HeaderItem("Favorite Apps");
listRowAdapter.add(list.get(0));
ListRow basicRow = new ListRow(headerItem,listRowAdapter);
rowsAdapter.add(basicRow);
}

I have the following views in my activity:
private Button btn;
private TextView txtView;
I have the following button click event:
private async void Btn_Click(object sender, System.EventArgs e)
{
var mDialog = new ProgressDialog(this);
mDialog.SetMessage("Loading data...");
mDialog.SetCancelable(false);
mDialog.Show();
string str;
await Task.Run((() => str = Foo()));
// Alternatively
// await Task.Delay(10000);
mDialog.Dismiss();
txtView.Text = str;
}
And I also have the following method:
string Foo()
{
for (int i = 0; i < 10; i++)
{
Thread.Sleep(1000);
}
return "hello";
}
What I want is txtView.Text to be set to hello after the ProgressDialog is dismissed
Task.Run is not meant to be used like that what it does is Queues the specified work to run on the ThreadPool and returns a task or Task<TResult> handle for that work.
What you should do is make a method with a return type of Task<string> and then await that method
Then use that method to update your textview data
Solution:
You can set a dismiss listener by using SetOnDismissListener to do some work after the ProgressDialog is dismissed.
First, let your activity inherit from IDialogInterfaceOnDismissListener:
public class MainActivity : AppCompatActivity, IDialogInterfaceOnDismissListener
In your button click event, set your activity as the listener:
private async void Btn_Click(object sender, System.EventArgs e)
{
var mDialog = new ProgressDialog(this);
mDialog.SetMessage("Loading data...");
mDialog.SetCancelable(false);
//set your activity as the listener
mDialog.SetOnDismissListener(this);
mDialog.Show();
await Task.Delay(10000);
mDialog.Dismiss();
}
Then you should implement the interface(IDialogInterfaceOnDismissListener) member OnDismiss, in this function, you can do whatever you want to do after the ProgressDialog is dismissed:
public void OnDismiss(IDialogInterface dialog)
{
Toast.MakeText(this, "You used the 'SetOnDismissListener'.", ToastLength.Long).Show();
txtView.Text = "hello";
}
You can refer:

I have the following problem:
My method opens a JDialog with a bunch of buttons (only one in example code). I want to click a button and thereby choose an ImageIcon for my method to return. But the Method does not wait for me to click a button. It opens the window and then returns an empty ImageIcon.
public class Kartenauswahl {
ImageIcon bandit;
public ImageIcon auswahlfenster() {
int bwidth = new Integer(150);
int bheight = new Integer(225);
bandit = new ImageIcon("cover/Bandit.jpe");
bandit.setImage(bandit.getImage().getScaledInstance(bwidth,bheight,Image.SCALE_DEFAULT));
final JDialog kartenwahl = new JDialog();
kartenwahl.setTitle("Kartenwahl");
kartenwahl.setSize(1500,1000);
kartenwahl.setVisible(true);
kartenwahl.setLayout(new FlowLayout());
ImageIcon returnicon= new ImageIcon();
final JButton b1 = new JButton(); //just to get the Icon out of the void loop
JButton B1 = new JButton(bandit); //this is going to be the button I want to click to choose the ImageIcon which is returned
B1.setContentAreaFilled(false);
B1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
b1.setIcon(bandit);
kartenwahl.dispose();
}
});
kartenwahl.add(B1);
returnicon = (ImageIcon) b1.getIcon();
return returnicon;
}
}
Question: can I bind the return statement to a condition? Like "only return after I clicked that Button B1"?
Hi sorry for the long wait. I have written an custom JDialog that should work for you.
public class CustomDialog extends JDialog {
JButton[] buttons;
ImageIcon selectedImageIcon;
public CustomDialog() {
setSize(500, 500);
setLayout(new GridLayout(4, 6));
ActionListener actionListener = new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
selectedImageIcon = ((ImageIcon) ((JButton) e.getSource()).getIcon());
dispose();
}
};
buttons = new JButton[24];
for(int i = 0; i < 24; i++) {
buttons[i] = new JButton(new ImageIcon("path_to_your_image_file"));
buttons[i].addActionListener(actionListener);
add(buttons[i]);
}
setVisible(true);
}
public ImageIcon getSelectedImageIcon() {
return selectedImageIcon;
}
}
The initial size is not that important the GridLayout is. you mentioned that you would need 24 buttons so I created an grid with 4 rows and 6 columns.
Then I create the buttons in a loop and adding the same Listener to set the selection icon with the icon of the pressed button. Afterwards I dispose the screen triggering an windowClosed event.
You could simply create this Dialog from your main class and wait for the response like so:
public class main {
public static void main(String[] args) {
CustomDialog customDialog = new CustomDialog();
customDialog.addWindowListener(new WindowAdapter() {
#Override
public void windowClosed(WindowEvent e) {
ImageIcon icon = customDialog.getSelectedImageIcon();
//do something with your icon
}
});
}
}
Don't forget to mark this answer as correct if it fixes your problem.
Have a good one!
I need to add header to a STOMP message currently it is working as below but i am recreating the message , is it possible to just add native header without having to recreate the message for performance .
public class MyChannelInterceptor extends ChannelInterceptorAdapter {
#Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
StompHeaderAccessor accessor = StompHeaderAccessor.wrap(message);
StompCommand command = accessor.getCommand();
if(command != null) {
log.debug("Receiving msg {} from {}",command,accessor.getUser().getName());
if(command == StompCommand.SEND) {
log.debug("Adding expires header to msg {} from {}",command,accessor.getUser().getName());
String ttlString = accessor.getFirstNativeHeader("ttl");
long ttl = 30000;
try {
ttl = Long.parseLong(ttlString);
}
catch(Exception ex) {
log.error("TTL header received but not in correct format {}",ttlString);
}
accessor.addNativeHeader("expires", Long.toString(System.currentTimeMillis() + ttl));
return MessageBuilder.createMessage(message.getPayload(), accessor.getMessageHeaders());
}
}
return message;
}
}
This is what i was looking for
StompHeaderAccessor accessor = MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class);
The above code will get the actual StompHeaderAccessor of the message so if you manipulate the native headers they are directly reflected on the message while
StompHeaderAccessor accessor = StompHeaderAccessor.wrap(message);
will get a clone of the headers and you have to create a new message with the new cloned headers
full fixed code below
#Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
StompHeaderAccessor accessor = MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class);
// StompHeaderAccessor accessor = StompHeaderAccessor.wrap(message);
if(accessor != null) {
StompCommand command = accessor.getCommand();
if(command != null) {
log.debug("Receiving msg {} from {}",command,accessor.getUser().getName());
if(command == StompCommand.SEND) {
log.debug("Adding expires header to msg {} from {}",command,accessor.getUser().getName());
String ttlString = accessor.getFirstNativeHeader("ttl");
long ttl = 30000;
if(ttlString != null) {
try {
ttl = Long.parseLong(ttlString);
}
catch(Exception ex) {
log.error("TTL header received but not in correct format {}",ttlString);
}
}
accessor.addNativeHeader("expires", Long.toString(System.currentTimeMillis() + ttl));
// I don't need any more to create a new message
//return MessageBuilder.createMessage(message.getPayload(), accessor.getMessageHeaders());
}
}
}
return message;
}
Since addNativeHeader succeeds, that indicates the message is still mutable - see addNativeHeader().
In any case, since the NATIVE_HEADERS message header is a MultiValueMap-valued header, you can update the header contents in-place.
Hence, there is no need to create a new message.
You would have to create a new message if you add a new header to the message itself (rather than updating the mutable contents of an existing header).
EDIT
I just ran a test; as long as the message is still mutable, you can change it...
#Test
public void test() {
Map<String, Object> map = new HashMap<String, Object>();
MutableMessageHeaders headers = new MutableMessageHeaders(map);
Message<String> message = MessageBuilder.createMessage("foo", headers);
StompHeaderAccessor accessor = StompHeaderAccessor.wrap(message);
accessor.addNativeHeader("foo", "bar");
System.out.println(message.getHeaders().get(NativeMessageHeaderAccessor.NATIVE_HEADERS));
accessor.setImmutable();
try {
accessor.addNativeHeader("baz", "qux");
fail("expected IllegalStateException");
}
catch (IllegalStateException e) {
}
}
That said, are you experiencing a performance problem or is this just a perceived issue. Message creation is not expensive.
I'm trying to list all the available phone numbers with display name from contacts app in a ListView with search. Also if a contact has more than one phone number, it has to be displayed in separate list item (as different contact not as same contact in Contacts App).
I've successfully retrived all the phone numbers with display name and displayed in ListView. Multiple phone numbers of a contact also displayed as separate contact.
But, when I search - either it gives irrelevant phone number for the display name or it fails to filter when I entered single character. Please suggest on this.

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
}
}
}
}
};
