DialogFragment fullscreen shows padding on sides

Question

I am creating a custom DialogFragment that is displayed underneath the actionbar. So far everything works great. The layout parameters for dialog fragment are match_pa

Answer 1

I met the issue before: there is always a padding while having set fullscreen. try this code in dialogFragment's onActivityCreated() method:

public void onActivityCreated(Bundle savedInstanceState)
{   
    Window window = getDialog().getWindow();
    LayoutParams attributes = window.getAttributes();
    //must setBackgroundDrawable(TRANSPARENT) in onActivityCreated()
    window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    if (needFullScreen)
    {
        window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    }
}
