我添加了AdMob的横幅挂在我的应用程序成功。当旗帜看来我需要得到它的高度，以调整所有布局元素。我使用的情况下onReceivedAd，这是正确解雇。然而，alturaBanner是= 0，那么，如何得到它的高度？谢谢你。

  / **收到广告时调用。 * /
    @覆盖
    公共无效onReceiveAd（广告广告）
    {
        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_TAGonReceiveAd）;
      Toast.makeText（这一点，onReceiveAd，Toast.LENGTH_SHORT）.show（）;
    }
 

解决方案

获得之前，它是prepared总是会把你返回0视图的高度。 使用下一个code，以获得其正确的大小，无论你有何种设备/屏幕：

 私有静态无效runJustBeforeBeingDrawn（最终视图中查看，最终可运行可运行）
{
    最终ViewTreeObserver VTO = view.getViewTreeObserver（）;
    最终在preDrawListener preDrawListener =新在preDrawListener（）
    {
        @覆盖
        在preDraw公共布尔（）
        {
            runnable.run（）;
            最终ViewTreeObserver VTO = view.getViewTreeObserver（）;
            vto.removeOn preDrawListener（本）;
            返回true;
        }
    };
    vto.addOn preDrawListener（preDrawListener）;
}
 

在给定的可运行的，可以查询视图的实际大小。

另外，你可以用它代替插件preDrawListener addOnGlobalLayoutListener如果你想。

另一种方法是使用onWindowFocusChanged（并检查hasFocus ==真），但是这并不总是最好的方法（仅使用简单的观点创造，而不是动态的创造）

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();
    }

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)
