在不同的标签上触摸 2 次时发生 Android 崩溃

Question

我认为我的标题不足以解释我的 android 何时会崩溃。我的应用程序上有 3 个选项卡小部件。这意味着我有 3 个 Activity (accountMainThread.java、TodayExpenseList.java 和 settingThread)适应每个选项卡小部件。这是我的选项卡 Activity 代码。

    TabSpec mainSpec = addNewTab(tab1,android.R.drawable.ic_menu_upload);           
    Intent mainIntent = new Intent(AccountTabActivity.this,accountMainThread.class);
    mainSpec.setContent(mainIntent);            
    tabHost.addTab(mainSpec);           

    TabSpec todayExpenseListSpec = addNewTab(tab2,android.R.drawable.ic_menu_today);                
    Intent todayExpenseListIntent = new Intent(AccountTabActivity.this,TodayExpenseList.class);         
    todayExpenseListSpec.setContent(todayExpenseListIntent);
    tabHost.addTab(todayExpenseListSpec);       

    TabSpec settingSpec = addNewTab(tab3,android.R.drawable.ic_menu_manage);
    Intent settingIntent = new Intent(AccountTabActivity.this,settingThread.class);
    settingSpec.setContent(settingIntent);
    tabHost.addTab(settingSpec);

这只是我工作的一部分。好吧，我的应用程序将从第一个选项卡 (accountMainThread) 开始，并且应用程序运行良好。然后，我选择第二个选项卡 (todayExpenseList)，仍然是一样的，没有错。然后，我选择第三个选项卡(settingThread)并且仍然相同，没有错。问题是当我为下一个选项卡选择任何选项卡时，第一个选项卡或第二个选项卡或第三个选项卡，我的应用程序崩溃了。我希望我的解释足够理解。

这是我完整的 tabActivity 代码

如果需要，我会提供任何解释和代码。我已经处理这个问题一天了。我真的希望有人能帮我解决这个问题。谢谢

Answer 1

感谢所有花时间帮助解决这个问题的人。我发现了我的问题。在 TodayExpenseList.java 中，关于 onPause 生命周期方法。我试图关闭使我的应用程序崩溃的 SQLlite 数据库。在我删除 onPause 方法上的 SQLlite 数据库 close() 方法后，一切都变得很好。
