問題是你打電話setChoiceMode()和setMultiChoiceModeListener()你OnItemLongClickListener，這意味着這些方法將不會被調用，直到你執行一個列表項長時間點擊裏面。

把editListView.setChoiceMode()和editListView.setMultiChoiceModeListener()您OnItemLongClickListener之外：

editListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL); 
editListView.setMultiChoiceModeListener(new ListView.MultiChoiceModeListener() { 
    // ... 
} 

editListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { 
    // ... 
}
