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

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

This Worked!!!

Answer 2

if you create childs of layout in activity dynamically and you go to another activity if you return you must remove views and recreate it with new informations.
