Get root view from current activity

Question

I know how to get the root view with View.getRootView(). I am also able to get the view from a button\'s onClick event where the argument is a View. But how can

Answer 1

if you are in a activity, assume there is only one root view,you can get it like this.

ViewGroup viewGroup = (ViewGroup) ((ViewGroup) this
        .findViewById(android.R.id.content)).getChildAt(0);

you can then cast it to your real class

or you could using

getWindow().getDecorView();

notice this will include the actionbar view, your view is below the actionbar view
