I'm trying to get the background of a DialogFragment
to be completely clear.
With setting the style item android:windowIsFloating
to true (the default),
the DialogFragment
displays exactly how I want it to, but has a very dimmed background.
By setting android:windowIsFloating
to false, I get the clear background I want, but the DialogFragment blows up to about 95% of the screen,
leaving only a tiny gap around it where you can see through to the view it overlays.
I've tried ton's of tweaks and cannot seem to override this behavior.
Do I need to use a PopupWindow
to achieve the desired effects, or are there some style
items that I can override ?
What works for me is to adjust the WinowManager.LayoutParams
in onStart()
of the DialogFragment:
@Override public void onStart() {
super.onStart();
Window window = getDialog().getWindow();
WindowManager.LayoutParams windowParams = window.getAttributes();
windowParams.dimAmount = 0.90f;
windowParams.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(windowParams);
}
