我認爲我的標題不足以解釋我的android何時會崩潰。我的應用程序中有3個標籤小部件。這意味着我有3個活動（accountMainThread.java，TodayExpenseList.java和settingThread）適應每個選項卡小部件。這是我的標籤活動代碼。當在不同標籤上觸摸2次時發生Android崩潰
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);
這只是我工作的一部分。那麼，我的應用程序將從第一個選項卡（accountMainThread）開始，並且應用程序工作正常。然後，我標籤第二個選項卡（todayExpenseList）仍然一樣，沒有錯。然後，我標籤第三個選項卡（settingThread），仍然是一樣的，沒有錯。問題是當我選擇下一個選項卡時，無論是第一個選項卡還是第二個選項卡還是第三個選項卡，我的應用程序都崩潰了。我希望我的解釋很好理解。
