android - 使用 WindowManager 覆盖布局时，后退按钮不起作用。如何让它发挥作用？

Question

LayoutInflater li = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);

    params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY | WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
            WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
            PixelFormat.TRANSLUCENT);
    params.gravity = Gravity.RIGHT | Gravity.TOP;
    myview = li.inflate(R.layout.locked_layout, null);
    wm.addView(myview);

这是我用来在屏幕上叠加布局的代码。只有 HOME 键有效。但是后退按钮不起作用。我希望两者都能工作。我错过了什么吗？请帮我!!提前致谢

WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
