Help - Focus problem after modifing android OS codes

[yangjl]

I am a developer from Giayee ( Android phone OEM/ODM ) . We are now customizing an android phone for an Indonesia client. I come accross a problem with the UI. Because the LCD of android phone cutomized by us is smaller than the default setting in android OS codes, so some UI elements should be modified to be suitable to the smaller LCD. But when I changed all the UI elements smaller, the trackball can't be focused on those UI elements. Anyone come accross this problem? Please help me. Thanks!

Hello, today I resolved a focus problem. Hope this will give you some help.
The keypoint lies in the 'touchMode' of android. Developer from JavaSpring platfrom will concentrate on setFocusable（）and requestFocus(). But there are two others functions in Android: setFocusableInTouchMode() and requestFocusFromTouch(). These two are the keypoint for focus problem in Android.

And there is a isInTouchMode() function in class 'View', this can help us monitor whether click() is exeucted during 'Focuse' event time. You can see the codes below:

ImageButton.OnFocusChangeListener mFocusChangeListener = new ImageButton.OnFocusChangeListener(){

public void onFocusChange(View v, boolean hasFocus) {
Log.d("FocuseChange", "Focuse has changed.");
if (hasFocus) {

// If it is touchmode, click is executed. Otherwise it is on be highlighted
v.setBackgroundDrawable(getResources().getDrawable (R.drawable.));

if (v.isInTouchMode()){

((ImageButton)v).performClick();
}
} else {
v.setBackgroundDrawable(getResources().getDrawable (R.));
v.getBackground().setAlpha(100);
}

}
};
