In my activity there are two views. Both are in different parents. I have their coordinates with respect to the screen. How to interchange the location of the two views?

推荐答案

您将需要调用父的ViewGroup方法 removeView（）这两个观点则 addView（）添加对方而是交换技术。

You will need to call the parent ViewGroup method removeView() for both views then addView() to add them back but swapper about.

所以，如果你的父母的意见被称为妈妈和爸爸，人们有一个孩子叫foo，那么其他的孩子叫吧：

So if your parent views are called mommy and daddy, one has a child called foo, the other a child called bar:

ViewGroup daddy = (ViewGroup)findViewById(R.id.daddy);
ViewGroup mommy = (ViewGroup)findViewById(R.id.mommy);

View foo = findViewById(R.id.foo);
View bar = findViewById(R.id.bar);

//detach children

daddy.removeView(foo);
mommy.removeView(bar);

//re-attach children

daddy.addView(bar);
mommy.addView(foo);

阅读有关removeView更多信息的ViewGroup 参考addView方法和看其他可用的方法。
