I have a code similar to the one below, painting over the mapfields this mIcon several times.
How can I add a click listener to this bitmap ? I am using bb 5.0
public Bitmap mIcon;
mIcon = Bitmap.getBitmapResource("pcture1.png");
protected void paint(Graphics g) {
super.paint(g);
mDest = new XYRect(....);
g.drawBitmap(mDest, mIcon, 0, 0);
}
Override BitmapField and modify the isFocusable(), navigationClick(), keyChar(), and trackwheelClick() methods.
public class ImageButtonField extends BitmapField
{
public ImageButtonField(Bitmap image)
{
super(image);
}
public boolean isFocusable()
{
return true;
}
protected boolean navigationClick(int status, int time)
{
fieldChangeNotify(0);
return true;
}
protected boolean trackwheelClick(int status, int time)
{
fieldChangeNotify(0);
return true;
}
protected boolean keyChar(char character, int status, int time)
{
if(Characters.ENTER == character || Characters.SPACE == character)
{
fieldChangeNotify(0);
return true;
}
return super.keyChar(character, status, time);
}
}

It works fine in Android and Desktop. But when running on iOS, it doesn't respond any input event.
I'm using gdxVersion 1.9.5, multi-os engine 1.2.3
I wrote a test class extends input adapter and override touchDown and touchUp method. But it doesn't respond any of the input events which work fine in Android.
public class TestScreen extends ScreenAdapter implements InputProcessor {
private CardGame game;
private OrthographicCamera guiCam;
public TestScreen(CardGame game){
this.game = game;
guiCam = new OrthographicCamera(Consts.WORLD_WIDTH, Consts.WORLD_HEIGHT);
Gdx.input.setInputProcessor(this);
}
public void draw () {
GL20 gl = Gdx.gl;
gl.glClearColor(1, 0, 0, 1);
gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
guiCam.update();
}
public void render (float delta) {
draw();
}
#Override
public boolean keyDown(int keycode) {
System.out.println("key down");
return true;
}
#Override
public boolean keyUp(int keycode) {
System.out.println("key up");
return true;
}
#Override
public boolean keyTyped(char character) {
System.out.println("key typed");
return true;
}
#Override
public boolean touchDown(int screenX, int screenY, int pointer, int button) {
System.out.println("touch down");
return true;
}
#Override
public boolean touchUp(int screenX, int screenY, int pointer, int button) {
System.out.println("touch up");
return true;
}
#Override
public boolean touchDragged(int screenX, int screenY, int pointer) {
System.out.println("touch dragged");
return true;
}
#Override
public boolean mouseMoved(int screenX, int screenY) {
System.out.println("mouse moved");
return true;
}
#Override
public boolean scrolled(int amount) {
System.out.println("scrolled");
return true;
}
}
How would I go about creating a custom ButtonField that includes an icon? I have found several different sources for a ButtonField with a custom background Bitmap, but I want to have a button with an Icon and text under it. I can not find anyt informaiton about this, maybe someone here could help me out?
Cheers

I don't have problem in testing by using Simulator. But i am not able to navigate to button in Real device. I am using 9780 Blackberry bold device. I dont know where the problem occur
Try to do the following:
1). Remove this stuff:
protected boolean navigationMovement(int dx, int dy, int status,int time)
{
return true;
}
protected boolean trackwheelRoll(int dir, int status, int time)
{
return true;
}
2). Make sure your field IS focusable. As the docs say:
If you want your field to receive the
focus, then you must override
isFocusable to return true.
P.S. Actually you don't need to override the touchEvent(TouchEvent message). Check my another post on this.

Try adding Field.EDITABLE to your style for the EditField.
I have created a custom button and i am placing the bunch of Custombuttons in a verticalfieldManager , I have aligned the verticalField Manager in the center. when i am creating a default buttonField then verticalfield Manager is able to align the buttonfield in the center. but when i am assigning custombuttonfield in the verticalField Manager it's not aligning in the center.
here is my custombuttoncode
public CustomButtonField(String label,long style) {
super(style);
this.label = label;
onPicture = Bitmap.getBitmapResource(onPicturePath);
font = getFont();
this.setPadding(5,5, 5, 5);
}

return label;
}
public int getPreferredHeight() {
return onPicture.getHeight();

When you create the button you need to pass the Field.FIELD_HCENTER flag as one of your style flags.
CustomButtonField button = new CustomButtonField("TestLabel", Field.FIELD_HCENTER);
