Android-包含broadcastreceiver的异常完成类
我创建了一个类，在类构造函数中，我为SMS创建了一个广播接收器，并在finalize方法类中取消注册接收器 现在：我的应用程序有3个选项卡，每个选项卡都有活动，当我创建类的实例（为当前活动创建BroadcastReceiver）时，创建活动的OnCreate，并且OnStop我完成类的定稿 问题是，当我在标签中移动很多次时，我得到了强制关闭应用程序，这是本文最后一次显示的例外 MYCLASS代码：Android-包含broadcastreceiver的异常完成类,android,Android,我创建了一个类，在类构造函数中，我为SMS创建了一个广播接收器，并在finalize方法类中取消注册接收器 现在：我的应用程序有3个选项卡，每个选项卡都有活动，当我创建类的实例（为当前活动创建BroadcastReceiver）时，创建活动的OnCreate，并且OnStop我完成类的定稿 问题是，当我在标签中移动很多次时，我得到了强制关闭应用程序，这是本文最后一次显示的例外 MYCLASS代码： package com.example.tawasol1; import android.con

onCreate活动不再可见，就会调用onStop
方法
因此，下次您的活动
未显示时，您将尝试注销已注销的接收器
您可以将您的接收器
创建移动到onResume
方法，该方法在每次显示活动
时调用
您可以看到，活动
生命周期finalize（）确实不是注销接收器的好地方。例如，您是否尝试将其移动到activity onPause（）callback？在finalize类中，我会注销receiver，但在activity的OnStop事件中，我会将其移动到finalize类。当您移动到另一个选项卡并创建所选选项卡时，这些选项卡会破坏活动。所以我认为OnCreate和OnStop是创建和销毁接收器的正确位置。您使用的是哪种选项卡组件？
