When adding view inside layout and when removing and re-adding IllegalStateException

Question

When adding view inside layout and when removing and re-adding, it throws like this.

The specified child already has a parent. You must call removeView() on the child's parent first

Any Idea???

linearLayout.addView(view);

This line is called often(ie. everytime when activity resumes), so i've added like:

((ViewGroup)view.getParent()).removeAllViewsInLayout();
linearLayout.removeView(view);
if(linearLayout.getChildCount()==0)
    linearLayout.addView(view);

But again same probs!

Answer 1

如果您在活动中动态创建布局子级，并且如果返回则转到另一个活动，则必须删除视图并使用新信息重新创建它。

Answer 2

((ViewManager)view.getParent()).removeView(view);

这工作！！！
