View Code

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:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
