我正在尝试显示一个浮动小部件

但是当我在两台小米红米设备上运行该应用程序时收到此错误消息

CreateServiceData{token=android.os.BinderProxy@23c3153 className=com.xyz.x.FloatingViewService packageName=com.xyz.com intent=null}"

所以我在 SO 上搜索并想出了下面的解决方案并且它有效

//Add the view to the window.
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
                    //WindowManager.LayoutParams.TYPE_PHONE,
                    WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

但现在它在我试过的其他手机上显示这条消息，比如三星和vivo

android.view.WindowManager$BadTokenException:Unable to add window android.view.ViewRootlmpl$W@25a1f437 -- permission denied for this window type"

如果我这样做，效果很好

//Add the view to the window.
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
  WindowManager.LayoutParams.TYPE_PHONE,
 //WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

如果我将WindowManager.LayoutParams.TYPE_PHONE,它设置在三星和vivo上，天知道在哪些手机上，但它不适用于红米手机

如果设置WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,它，它适用于红米手机而不是其他手机。

任何建议请这里的任何东西都是完整的代码

        //Inflate the floating view layout we created
        View mFloatingView = LayoutInflater.from(this).inflate(R.layout.layout_floating_widget, null);

        //Add the view to the window.
        final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
              WindowManager.LayoutParams.TYPE_PHONE,
//                WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                PixelFormat.TRANSLUCENT);

        //Specify the view position
        params.gravity = Gravity.TOP | Gravity.LEFT;        //Initially view will be added to top-left corner
        params.x = 0;
        params.y = 100;

        //Add the view to the window
        mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
        mWindowManager.addView(mFloatingView, params);
