I try to change brightness when dialog fragment opened,i insert this code on oncreate() but it change only for one second. 

    try {
        curBrightnessValue = Settings.System.getInt(
                getActivity().getContentResolver(), Settings.System.SCREEN_BRIGHTNESS);

        WindowManager.LayoutParams layout = getActivity().getWindow().getAttributes();
        layout.screenBrightness = 1F;
        getActivity().getWindow().setAttributes(layout);

    } catch (Settings.SettingNotFoundException e) {
        e.printStackTrace();
    }

In main fragment it works

  • I found the problem: `setStyle(DialogFragment.STYLE_NORMAL, R.style.MppTheme_FullScreenDialog);` I set a full-screen dialog with this code, if i remove it brightness work fine. How i can set in other way the full-screen fragment dialog? – tecn603 Jun 18 '19 at 19:47
