在调试代码中，报错误如下:

在报错中提示:
Unable to add window android.view.ViewRootImpl$W@4103e4c0 -- permission denied for this window type
原因是:
发现在使用WindowManager.LayoutParams.TYPE_SYSTEM_ALERT涉及到window type权限问题。
修改代码如下:
在Mainfest.xml中添加window 权限:
<!-- 显示系统窗口权限 -->
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<!-- 在 屏幕最顶部显示addview-->
<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
