Try this

   params = new WindowManager.LayoutParams(
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.MATCH_PARENT,
                    WindowManager.LayoutParams.TYPE_SYSTEM_ERROR, WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED,
                    PixelFormat.TRANSLUCENT);
            params.gravity = Gravity.TOP;

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            } else {
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            }
    mOverlay = (RelativeLayout) inflater
                    .inflate(R.layout.main, (ViewGroup) null);

    mOverlay.setFitsSystemWindows(false);
            getWindow().getDecorView().setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
            mWindowManager = (WindowManager) context
                    .getSystemService(Context.WINDOW_SERVICE);
            mWindowManager.addView(mOverlay, params);
