问题描述

在调用所有布局方法，所有View都就位并且Activity准备好显示之后，我需要在Activity中做些事情.

I need to do something in an Activity after all the layout methods have been called, all the Views are in place and the Activity is ready to be displayed.

哪种方法可以做到?

推荐答案

如果要获取视图宽度或其他宽度.这应该工作

If you are trying to get a width of a view or something. This should work

将此添加到您活动的onCreate

Add this to your activity's onCreate

ViewTreeObserver vto = layout.getViewTreeObserver(); 
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() { 
    @Override 
    public void onGlobalLayout() { 
        // Put your code here. 

        layout.getViewTreeObserver().removeOnGlobalLayoutListener(this); 
    } 
});
