Full Screen DialogFragment in Android

To get DialogFragment on full screen

Override onStart of your DialogFragment like this:

@Override
public void onStart()
{
    super.onStart();
    Dialog dialog = getDialog();
    if (dialog != null)
    {
        int width = ViewGroup.LayoutParams.MATCH_PARENT;
        int height = ViewGroup.LayoutParams.MATCH_PARENT;
        dialog.getWindow().setLayout(width, height);
    }
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setStyle(DialogFragment.STYLE_NORMAL,
             android.R.style.Theme_Black_NoTitleBar_Fullscreen);
}
