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 个活动（accountMainThread.java、TodayExpenseList.java 和 settingThread）适应每个选项卡小部件。这是我的标签活动代码。
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，并且应用程序工作正常。然后，我选择第二个标签（todayExpenseList），还是一样，没有错。然后，我标签第三个标签（settingThread），仍然一样，没有错。问题是当我为下一个选项卡选择任何选项卡时，无论是第一个选项卡还是第二个选项卡或第三个选项卡，我的应用程序都崩溃了。我希望我的解释足够理解。
