Android ListView沒有反應

我有ListView和Adapter的問題。 ListView setOnItemClickListener和setOnItemLongClickListener不響應，但onScroll完美工作。這裏的代碼，你可能有我的解決方案...Android ListView沒有反應

在此先感謝。

public class AFragment extends Fragment { 

View rootView; 
ListView l; 
public static AArrayAdapter adapter; 

public AFragment() { 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    rootView = inflater.inflate(R.layout.fragment_list, container, false); 
    return rootView; 
} 

@Override 
public void onViewCreated(View view, Bundle savedInstanceState){ 
    l = (ListView) rootView.findViewById(R.id.listView); 

    adapter = new AArrayAdapter(getActivity(), R.layout.list_item_adapter, new ArrayList<AString>()); 
    l.setAdapter(adapter); 

    l.setOnItemLongClickListener(new OnItemLongClickListener() { 
     public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) { 
      //Toast doesn't work 
      return true; 
     } 
    }); 

    aList(); 

    l.setOnScrollListener(new OnScrollListener() { 
     private int mLastFirstVisibleItem; 

     @Override 
     public void onScrollStateChanged(AbsListView view, int scrollState) { 
      // 
     } 
     @Override 
     public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { 
      if (mLastFirstVisibleItem < firstVisibleItem) { 
       // working 
      } 
      if (mLastFirstVisibleItem > firstVisibleItem) { 
       // working 
      } 
      mLastFirstVisibleItem = firstVisibleItem; 
     } 
    }); 

    l.setOnItemClickListener(new OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
      //Toast doesn't work 
     } 
    }); 
} 

public void aList(){ 
    ... 
}

public class AArrayAdapter extends ArrayAdapter<AString> { 
    private final Context context; 
    private List<AString> items; 

    public AArrayAdapter(Context context, int layoutResourceId, List<AString> items) {

     rowView.setTag(holder); 

     setupItem(holder);

     holder.removeButton.setTag(holder.account); 

     holder.removeButton.setFocusable(false); // <=========== :) 
    } 

    public class AHolder { 
     AString account;

     TextView name; 
     TextView value; 
    }

您在監聽器方法中沒有任何代碼，您是否試圖顯示至少atast的toast？ – Keshav1234 2015-04-01 11:40:13

這正是我所嘗試的。 – Arnes 2015-04-01 12:02:15

檢查你的listview項目xml，如果它有任何focusable元素 - http://stackoverflow.com/questions/8955270/listview-items-are-not-clickable-why – random 2015-04-02 09:34:05

這是可能的副本 - ListView items are not clickable. why?

爲了解決這個問題，你一定沒有的ListView/GridView控件內的任何可獲得焦點項目。

所以對於按鈕/ ImageButtons必須設置：

android:focusable="false"

如果你有ListView控件/ GridView控件內的ImageButton的，你可以切換到一個ImageView的作爲按鈕將無法點擊不管怎樣，這樣你做不需要改變可聚焦性。

另外，作爲fpr0001中的鏈接規定提供給你也可以這樣做：

這裏這個答案爲我工作：https://stackoverflow.com/a/16536355/5112161

主要是他在的LinearLayout或RelativeLayout的添加了以下內容：
android:descendantFocusability="blocksDescendants" 
您還需要從您的所有xml中刪除以下內容：
android:focusable="false" 
android:focusable="true" 
android:clickable="true" 
android:clickable="false"

如果你有意見可點擊，按鈕或複選框的行中更好地利用Recyclerview。那將是一個更好choice.You可以找到Recyclerview here的基本實現。

按鈕或複選框單擊偵聽器會干擾listview點擊偵聽器。在行的根元素中，添加一個android:descendantFocusability="beforeDescendants",android:descendantFocusability="blocksDescendants"
另請嘗試爲按鈕添加android:focusable="false"。

這應該解決問題。
