ListView与自定义适配器，在片段内不会触发onItemClick事件

Question

我有一个ViewProvider类的片段内容，它为其中一个片段返回一个ListView。 ListView具有扩展BaseAdapter类的自定义适配器。当我尝试实现一个项目点击侦听器时，它不起作用。我有听众的代码：

lv.setOnItemClickListener(new ListView.OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> a, View vi, int pos, 
       long id) { 
     try { 
      Object o = lv.getItemAtPosition(pos); 
      Event obj_itemDetails = (Event) o; 
      Toast.makeText(context, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show(); 
      Log.d("xxx", "output: "+obj_itemDetails.getName()); 
     } catch(Exception e) { 
      Log.d(Log.TAG, "Something is wrong..."); 
     } 
    } 
}); 

...甚至没有例外发生。在同一个ViewProvider类中，我用SimpleAdapter添加了另一个列表，它工作得很好。我初始化列表相同：

EventAdapter sta = new EventAdapter(context, events); 
final ListView lv = new ListView(context); 
lv.setTextFilterEnabled(true); 
lv.setAdapter(sta); 

，另一种：

final ListView v = new ListView(context); 
String[] from = new String[] { "str" }; 
int[] to = new int[] { android.R.id.text1 }; 
List<Map<String, String>> items = new ArrayList<Map<String, String>>(); 
for (int i = 0; i < 20; i++)...//set the items here 
SimpleAdapter adapter = new SimpleAdapter(context, items, 
     android.R.layout.simple_list_item_1, from, to); 
v.setAdapter(adapter); 

我缺少什么，我应该在哪里看？

这里是我的EventAdapter：

public class EventAdapter extends BaseAdapter { 

private LayoutInflater mInflater; 

private List<Event> items = new ArrayList<Event>(); 

Context ctx; 

public EventAdapter(Context context, List<Event> items) { 
    mInflater = LayoutInflater.from(context); 
    this.items = items; 
    this.ctx = context; 
} 

public int getCount() { 
    return items.size(); 
} 

public Event getItem(int position) { 
    return items.get(position); 
} 

public long getItemId(int position) { 
    return position; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 
    ViewHolder holder; 
    final Event s = items.get(position); 
    if (convertView == null) { 
     convertView = mInflater.inflate(R.layout.list_item, null); 
     holder = new ViewHolder(); 
     holder.name = (TextView) convertView.findViewById(R.id.eventTitle); 
     holder.timestamp = (TextView) convertView.findViewById(R.id.eventTime); 
     holder.location = (TextView) convertView.findViewById(R.id.eventLocation); 
     holder.pic = (ImageView) convertView.findViewById(R.id.eventLogo); 
     convertView.setTag(holder); 
    } else { 
     holder = (ViewHolder) convertView.getTag(); 
    } 
    holder.name.setText(s.getName()); 
    holder.timestamp.setText(s.getTimestamp()); 
    holder.location.setText(s.getLocation()); 
    if (s.getImage() != null) { 
     holder.pic.setImageBitmap(s.getImage()); 
    } else { 
     // MY DEFAULT IMAGE 
     holder.pic.setImageResource(R.drawable.ic_launcher); 
    } 
    return convertView; 
} 

static class ViewHolder { 
    TextView name; 
    TextView timestamp; 
    TextView location; 
    ImageView pic; 
} 

}

上项目点击收听的ListView，如果您有任何focussable里面的物品自定义列表row.That是，如果您有任何按钮或progrees不火酒吧或任何控制，需要重点，onitemclick不会发射

我想建议你，活动和片段几乎相同，但差异是我们使用“this”或“ActivityName.this”我们必须取代它通过getActivity（）并声明va通过使用视图膨胀我们的类布局：

请确保您使用ListView查找按id这样的视图。

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     super.onCreateView(inflater, container, savedInstanceState); 
    // Inflate the layout for this fragment 
    View v = inflater.inflate(R.layout.yourlayoutfile, container, 
        false); 

    listView = (ListView) v 
        .findViewById(R.id.your_listview_id); 

    listView.setOnItemClickListener(YourFragmentClassName.this); 
} 

尝试通过实现onItemClickListener默认使用onItemClick侦听器。

@Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
     // TODO Auto-generated method stub 

     Log.d("OnItemClicked>>", "called"); 
} 

希望它会帮助你。
