Question

我有一个应用程序，它为所有其他正在运行的应用程序（基本上是作为后台服务运行的过滤器）引入半透明视图。我面临的问题是该应用程序不会在导航栏上应用过滤器（带有后面，主页和最近标签按钮的底栏）。

我用于创建视图的标志显示在下面的代码中：

 WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.MATCH_PARENT,
                WindowManager.LayoutParams.MATCH_PARENT,
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                0 | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
                PixelFormat.TRANSLUCENT);
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        wm.addView(mView, params);

是否有任何特殊标志或其他任何我需要覆盖导航栏的内容？

在layoutparams中添加Y偏移，使叠加层覆盖导航栏。

 WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.MATCH_PARENT,
                WindowManager.LayoutParams.MATCH_PARENT,0, navbarHeight(),
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                0 | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
                PixelFormat.TRANSLUCENT);
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        wm.addView(mView, params);

private int navbarHeight() {
...code to calculate height of navbar
}
