How can I add an loading dialog to my Browserfield when the page is loading?
Thanks
Use a GaugeField: net.rim.device.api.ui.component.GaugeField,
following the example at: http://docs.blackberry.com/en/developers/deliverables/18125/Gauge_field_1303006_11.jsp
Use BrowserFieldListener and use the following two functions in the class created:
public void documentCreated(BrowserField browserField, ScriptEngine scriptEngine, Document document) {
try{
System.out.println("Document Created");
UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() {
Dialog.alert("Loading");
}});
} catch (Exception ex) { }
}
public void documentLoaded(BrowserField browserField, Document document) {
try {
System.out.println("Document loaded");
UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() {
Dialog.alert("Finished Loading");
}});
} catch (Exception ex) { }
}

i am new in blackberry developer. i am use a pillsetbutton and pillfieldbutton
but when i am click pillfieldbutton no any action is performed.I am using setchangeListener() method.but no any Action is performed.i am going Through this process.
public DemoPill() {
PillButtonSet objButtonSet=new PillButtonSet();
final PillButtonField objButtonField1=new PillButtonField("NSE");
final PillButtonField objButtonField2=new PillButtonField("BSE");
objButtonSet.add(objButtonField1);
objButtonSet.add(objButtonField2);
this.add(objButtonSet);
bjButtonSet.setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
System.out.println("Hi ");
if(field==objButtonField1)
{
System.out.println("This Is NSE Button");
}
else if(field==objButtonField2)
{
System.out.println("This Is BSE Button");
}
}
});
}
}
You are printing it on console. So without debugging the code you will never know if your click is consumed. So just use an event thread to see the output on your screen. I have provided you the sample just check it. It will show the output on your screen. You can also use Dialog.inform(String message ) But its always good to do it on event thread.
public DemoPill() {
PillButtonSet objButtonSet=new PillButtonSet();
final PillButtonField objButtonField1=new PillButtonField("NSE");
final PillButtonField objButtonField2=new PillButtonField("BSE");
objButtonSet.add(objButtonField1);
objButtonSet.add(objButtonField2);
this.add(objButtonSet);
bjButtonSet.setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
// System.out.println("Hi ");
if(field==objButtonField1)
{
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
Dialog.inform("objButtonField1 button clicked")
}
});
}
else if(field==objButtonField2)
{
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
Dialog.inform("objButtonField2 button clicked")
}
});
}
}
});
}
}
May be this will help cheers. :)
You only can view the output of
System.out.println("ANYDATA");
in debug mode not in run.
Try to debug it not to run it.
I am developing a blackberry app. I want to open an screen from the home screen when user will press one button and hold it for 2 seconds.
Any way?
Thanks.
Here is the code for your question. I have make use of this BlackBerry LongClickListener implementation link which contains good explanation too.
public class HoldButtonScreen extends MainScreen implements FieldChangeListener {
ButtonField _btnHold;
Timer _timer;
public HoldButtonScreen() {
_btnHold = new ButtonField("Hold 2 sec to get popup")
{
protected boolean navigationClick(int status, int time) {
final Field _btnHold= this;
_timer = new Timer();
System.out.println("hi there");
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
try{
_timer.schedule(new TimerTask() {
public void run() {
fieldChanged(_btnHold, 0);
}}, 2000);
}catch(Exception e){
e.printStackTrace();
}
}
});
return true;
}
protected boolean navigationUnclick(int status, int time) {
System.out.println("hi unclick");
add(new LabelField("You have't hold button for 2 second."));
_timer.cancel();
return true;
}
};
_btnHold.setChangeListener(this);
add(_btnHold);
}
public void fieldChanged(Field field, int context) {
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
PopupScreen _popUpScreen = new PopupScreen(new VerticalFieldManager()){
public boolean onClose() {
close();
return true;
}
};
_popUpScreen.add(new LabelField("Hello , i am pop up after 2 second."));
UiApplication.getUiApplication().pushScreen(_popUpScreen);
}
});
}
}
Try this this will run successfully.
Just change the Screen in PushScreen.
private Thread splashTread;
protected int _splashTime = 200;
boolean countinue = true;
splashTread = new Thread() {
public void run() {
while (countinue == true) {
try {
synchronized (this) {
wait(_splashTime);
}
} catch (InterruptedException e) {
} finally {
synchronized (UiApplication.getUiApplication().getAppEventLock()) {
UiApplication.getUiApplication().pushScreen(new Login());
SplashScreen.this.close();
}
countinue = false;
}
}
}
};
splashTread.start();
When i click a button, in next screen i've loaded browserfield requestcontent() using thread.
and i've added browserfield listener.
when click back button , i came to first screen. But in background, requestContent is executing. how to stop it.?
i write the code on onClose() method
public boolean onClose()
{
for(int i=0;i<=Thread.activeCount();i++)
{
if(Thread.currentThread().isAlive())
{
Thread.currentThread().interrupt();
}
}
return super.onClose();
}
My code is.,
new Thread(new Runnable()
{
public void run()
{
loadWebContent(path);
}
}).start();
private void loadWebContent(String path)
{
final VerticalFieldManager vfm = new VerticalFieldManager(HORIZONTAL_SCROLL|VERTICAL_SCROLL)
{
protected void sublayout(int maxWidth, int maxHeight)
{
super.sublayout(maxWidth, (Display.getHeight()-47));
setExtent(maxWidth, (Display.getHeight()-47));
}
};
BrowserFieldConfig myBrowserFieldConfig = new BrowserFieldConfig();
myBrowserFieldConfig.setProperty(BrowserFieldConfig.NAVIGATION_MODE,BrowserFieldConfig.NAVIGATION_MODE_POINTER);
myBrowserField = new BrowserField(myBrowserFieldConfig);
myBrowserField.addListener(new BrowserFieldListener()
{
public void documentLoaded(BrowserField browserField,Document document) throws Exception
{
UiApplication.getApplication().invokeLater(new Runnable()
{
public void run()
{
try
{
mainlayout.delete(spinner);
mainlayout.add(myBrowserField);
myBrowserField.setZoomScale(1.0f);
}
catch (Exception e)
{
System.out.println("++ "+e);
}
}
});
}
});
myBrowserField.requestContent(path);
}
Pls help how to stop execution when back to first screen.
I think this is Enough:
public class LoadingScreen extends MainScreen
{
ButtonField click;
String url;
BrowserField browserField;
public LoadingScreen()
{
url="http://www.google.com";
browserField=new BrowserField();
add(browserField);
browserField.requestContent(url);
}
}
In onClose method:
public boolean onClose()
{
return super.close();
}
If you have any doubbts come on chat room named "Knowledge sharing center for blackberry and java" to clarify your and our doubts.
I want to create an call recorder application in blackberry. While searching in this forum i have got call-recorder-in-blackberry this link. The code given in the below link is fairly understood.
It might be a silly question to you experts but my question is how to us that piece of code. I mean the MyScreen object will work on UIApplication. But how can i make my module start while starting the device, and run in background waiting for the phone call listener to invoke.
I have used this below code, it records the call but only if the call is on loud speaker mode. Now how can i do the same without putting in loud speaker mode.

Actually direct call recording not possible with blackberry. AFAIK that posted code is call recording when call on speakerphone. That means If mobile have the loud speaker, then put a call to loud speaker and record that voice. And look at this discussion, Call recorder in Blackberry.
It's not possible to record the audio of a phone call (other than with a loud speakerphone) as you are trying to do. This is intentional. You would need another approach off the device to do this. However, I can answer your other questions:
To make your application autostart, you can follow these steps: http://supportforums.blackberry.com/t5/Java-Development/Configure-an-application-to-start-automatically-when-the/ta-p/444748
Also, as this application above doesn't extend from UiApplication, you should check the "run as a system module" box as well, when you follow the directions above. That way it won't appear on the ribbon or as an icon in the list of applications.
I'm giving localization support in my app in blackberry.Now the problem is i want to use system font in my application but the hieght should be constant.Now i want to use Status.show method to show some string on the screen.The string is coming from the resource bundle.
So kindly suggest how to set the font of that.
Thanx in advance

you can set a fields font with original style of it and given height(15) just like that:
setFont(getFont().derive(getFont().getStyle(),15));
