m300带屏遥控器上，我第二次添加FPVWidget到一个view里就报空指针了，加之前removeAllViews()了，堆栈如下： java.lang.NullPointerException: Attempt to invoke virtual method 'int android.view.ViewGroup.indexOfChild(android.view.View)' on a null object reference at dji.ux.widget.FPVWidget.initTextOverlay() at dji.ux.widget.FPVWidget.access$300() at dji.ux.widget.FPVWidget$3.run() at android.os.Handler.handleCallback(Handler.java:755) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:167) at android.app.ActivityThread.main(ActivityThread.java:6240) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1000) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:868)
