你好: 很感谢您的开源。我在运行代码时候发现问题,不知道您时候可以帮忙解决。

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.ice.floatingball, PID: 26974 android.view.WindowManager$BadTokenException: Unable to add window -- window android.view.ViewRootImpl$W@a981094 has already been added at android.view.ViewRootImpl.setView(ViewRootImpl.java:724) at android.view.WindowManagerGlobal.addView(WindowManagerGlobal.java:347) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:94) at android.widget.Toast$TN.handleShow(Toast.java:461) at android.widget.Toast$TN$2.handleMessage(Toast.java:344) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:163) at android.app.ActivityThread.main(ActivityThread.java:6368) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:901) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:791)

发现 是 Toast.makeText(context, "点击了悬浮球 执行后退操作", Toast.LENGTH_SHORT).show();的问题

然后这个悬浮球,切换到桌面，几秒后会消失
