废话不说了 直接上代码：

public  boolean hasMeasured = false;

//下面是主要实现 放在oncreate函数下就可以了

container = (FrameLayout) findViewById(android.R.id.tabcontent);

  ViewTreeObserver vto = container.getViewTreeObserver();

  vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {

   public boolean onPreDraw() {

    if (hasMeasured == false) {

     int height = container.getMeasuredHeight();

     int width = container.getMeasuredWidth();

      hasMeasured = true;

//LOG一下或者TOAST一下就可以了

    }

    return true;

   }

  });
