Removing a View from an Activity
提问by Emanuil Rusev
You've got a View defined in a layout file. How do you remove it from you Activity code?
您已经在布局文件中定义了一个视图。你如何从你的活动代码中删除它？
回答by Matt
ViewGroup vg = (ViewGroup)(myView.getParent());
vg.removeView(myView);
should do what you want as far as correctly removing the View from the Activity. The other guys' answer will just make the View invisible, using up resources.
应该做你想做的，只要正确地从活动中删除视图。其他人的回答只会使视图不可见，从而耗尽资源。

As Androidmentioned in a comment:
正如Android在评论中提到的：
view.setVisibility(View.GONE);
Quoting the Android reference:
引用 Android 参考：
This view is invisible, and it doesn't take any space for layout purposes.
这个视图是不可见的，它不占用任何布局空间。
I think it's the best solution unless you reallyneed to delete the object.
我认为这是最好的解决方案，除非您确实需要删除该对象。
