Adding view programmatically to a FragmentActivity dynamically

Question

I want to add a Image icon to be added on top of rootView in FragmentActivity.

I tried doing this:

 ViewGroup rootLayout = (ViewGroup) activity.findViewById(android.R.id.content);
            myView = activity.getLayoutInflater().inflate(R.layout.iconimage, null);
            rootLayout.addView(myView );
            rootLayout.invalidate();

But realised that this only works for AppCompatActivity, and doesn't work for FragmentActivity. As my image cannot be seen.

How can i add Views to Classes that extends FragmentActivity?

hi @GeniusQ, I tried putting simple xml layout. Even if it's just one linearlayout with match_parent for width and height it won't display the image icon. — Mysterious_android, Oct 27 '17 at 04:56
Did you LinearLayout have id? I saw you find your rootView with the id come from android.R.id, not R.id. — nhoxbypass, Oct 27 '17 at 04:58
yes, but `android.R.id.content` directly references the root view of your activity https://stackoverflow.com/questions/4486034/get-root-view-from-current-activity. I don't want to rely on ids — Mysterious_android, Oct 27 '17 at 05:00

AppCompatActivity is a subclass of FragmentActivity so all features of FragmentActivity will be available in AppCompatActivity.

So making your activity extend AppCompatActivity should hopefully solve your problem.
