android get adMob banner height when appears
admob, android, eclipse, java
Solution
getting the height of the view before it was prepared will always return you 0 . use the next code in order to get its correct size , no matter which device/screen you have:
private static void runJustBeforeBeingDrawn(final View view, final Runnable runnable)
{
final ViewTreeObserver vto = view.getViewTreeObserver();
final OnPreDrawListener preDrawListener = new OnPreDrawListener()
{
@Override
public boolean onPreDraw()
{
runnable.run();
final ViewTreeObserver vto = view.getViewTreeObserver();
vto.removeOnPreDrawListener(this);
return true;
}
};
vto.addOnPreDrawListener(preDrawListener);
}
inside the given runnable , you can query the real size of the view.
alternatively , you can use addOnGlobalLayoutListener instead of addOnPreDrawListener if you wish.
another approach is to use onWindowFocusChanged (and check that hasFocus==true) , but that's not always the best way ( only use for simple views-creation, not for dynamic creations)

Problem
I am adding an adMob banner to my app successfully. When banner appears I need to get its height in order to resize all layout elements. I am using the event onReceivedAd, that is properly fired. However, alturaBanner is = 0. Then, how to get its height? thank you. ``` /** Called when an ad is received. */ @Override public void onReceiveAd(Ad ad) { adView.setVisibility(View.VISIBLE); int alturaBanner = adView.getHeight(); RelativeLayout.LayoutParams params1 = (android.widget.RelativeLayout.LayoutParams) browse2 .getLayoutParams(); params1.setMargins(0, alturaBanner, 0, 0); Log.d(LOG_TAG, "onReceiveAd"); Toast.makeText(this, "onReceiveAd", Toast.LENGTH_SHORT).show(); } ```
