获取控件大小和设置调整控件的位置XY示例

网上很多人对设置控件的位置都使用view.setpadding(left, top, right, bottom) ，其实这玩意很差劲，它是设置自己本身位置的偏移，我们很少需要这种效果，我需要的设置控件相对屏幕左上角的x 、y位置。众里寻他千百度，蓦然回首，那人却在灯火阑珊处！

int h = view.measurespec.makemeasurespec(0,view.measurespec.unspecified);
view.measure(w, h);
return (view.getmeasuredwidth());

view.measure(w, h);
return (view.getmeasuredheight());
}
