android View 绘制完成监听的实现方法

//view重绘时回调
view.getViewTreeObserver().addOnDrawListener(new OnDrawListener() {		
	@Override
	public void onDraw() {
	// TODO Auto-generated method stub
		
	}
});

//view加载完成时回调
view.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
	@Override
	public void onGlobalLayout() {
	// TODO Auto-generated method stub
			
	}
});
