onChildClickListener在ExapandableListView中未响应

为什么Log未打印？所有其他人的日志正在工作，但不是为了孩子。onChildClickListener在ExapandableListView中未响应

文本视图的日志确实出现，但是当我使用编辑文本时，它不起作用。

为什么这么说？我哪里错了？

ExpandableListView expListView; 

expListView = getExpandableListView(); 

expListView.setAdapter(new ExAdapter(this)); 

     expListView.setOnGroupExpandListener(new OnGroupExpandListener() { 

      @Override 
      public void onGroupExpand(int groupPosition) { 
       // TODO Auto-generated method stub 

      } 

     }); 

     expListView.setOnGroupCollapseListener(new OnGroupCollapseListener() { 

      @Override 
      public void onGroupCollapse(int groupPosition) { 
       // TODO Auto-generated method stub 

      } 

     }); 

     expListView.setOnChildClickListener(new OnChildClickListener() { 

      @Override 
      public boolean onChildClick(ExpandableListView parent, View v, 
        int groupPosition, int childPosition, long id) { 
       Log.i("Tag", "-------------------------------------------------"); 
       return true; 
      } 

     });

代码编辑---------

@Override 
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) { 

    if(convertView == null) { 
     LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     convertView = inflater.inflate(R.layout.name_child, null); 

    } 

    TextView txtFName = (TextView) convertView.findViewById(R.id.txtFname); 
    txtFName.setText(arrChildhintelements[groupPosition][childPosition]); 


    editFName = (EditText) convertView.findViewById(R.id.editFName); 
    editFName.setHint(arrChildhintelements[groupPosition][childPosition]); 


    editFName.setOnTouchListener(new OnTouchListener() { 

     @Override 
     public boolean onTouch(View v, MotionEvent event) { 

      //doing somthing.... 

      return false; 
     } 

    }); 

    return convertView; 
}

没有....没有结果....通过使可编辑的虚假事实...它已经停止向我显示我需要的键盘。 – 2012-01-09 06:53:31

你可以在EditText或ListItem上有焦点事件，我建议你让editText完全不可编辑，因为它会获得焦点/选择/点击事件，如果你需要在editText上键盘/焦点事件，为什么不在editText上添加一个监听器在getChildView方法中。 – jeet 2012-01-09 07:00:01

我完成了，但它是交换的问题。我在一个编辑文本中编写了一些东西，但它反映在其他编辑文本中。 – 2012-01-09 07:04:32

没有看到代码，这只是一个猜测，但childCLickListener可使用该事件所以它不是到达编辑文字，尝试在childClickListener

返回false

好吧，我刚刚创建了一个小的项目，你r代码，我无法让onCildClickListener触发，将其更改为TextView，并且工作正常。它与EditText有关（可能是它消耗事件，或者它没有注册为点击，但是作为焦点的变化，但我只是在猜测这一点）。

所以在回答你的问题时，有可能 - 我不这么认为。但是我做了一个可能有用的小解决方法。

连接的onTouchListener（）到的EditText和检查MotionEvent.ACTION_DOWN

将

myList.setOnChildClickListener(listAdapter);

在onCreate方法。

然后onChildClick方法立即开始工作。
