How to remove a layout that was added using addContentView()?

Question

I am adding a layout using addContentView(). How can i remove this layout on a Button click ?

Answer 1

Assuming contentView is the view that was added via window.addContentView()

((ViewGroup) contentView.getParent()).removeView(contentView);

Answer 2

try it

View youAddedView;
ViewGroup rootView = (ViewGroup) findViewById(android.R.id.content);
for (int i = 0; i < rootView.getChildCount(); i++) {
    if(rootView.getChildAt(i) == yourAddedView) {
        // do anything here
    }
}

Answer 3

If you already have the reference to the view you can simply just do :

ViewGroup rootView = (ViewGroup) findViewById(android.R.id.content);
rootView.removeView(viewToRemove);

Instead of looping through the ViewGroup.

Answer 4

Unfortunately there's no way of removing a content view that was added with addContentView(). The best you can you do is to call setVisibility(View.GONE) on it, to hide it.

That is why the activity's onContentChanged() only gets called when the content view is set or added to an activity.
