Android OnCreate()中获取控件高度与宽度两种方法详解

 
    int w = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
    int h = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
    ssidtext.measure(w, h);
    int width =ssidtext.getMeasuredWidth();
    int height =ssidtext.getMeasuredHeight();

    ViewTreeObserver vto = ssidtext.getViewTreeObserver();
    vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
      public boolean onPreDraw() {
        int height = ssidtext.getMeasuredHeight();
        int width = ssidtext.getMeasuredWidth();
        return true;
      }
    });
