我不知道你能不能看到这只能通过代码... 但如果班上有没有一个onClick我的服装适配器，什么事都不会发生.. 。了Android不使用“的项目点击收听”点击收听+复选框 - Android电子

但它确实对“点击”方法的工作....

的问题是：我没有位置，我真正需要的...

希望任何人都可以帮助我在！谢谢你们！

试试这个监听onitemclicklistener会给你的列表视图 –

它dosent ...的选定位置，因为在项目点击监听器上一个列表...这不是一个列表... –

当用户点击复选框时，你想检测到？ – simekadam

您可以使用此事件收到通知的复选框被选中/取消

cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 

    @Override 
    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) { 

    } 
}

它仍然dosnt给我我正在使用哪一行...只有当我将把位置作为最终.... –

有没有问题，使位置final..it真的不应该改变为一个特定的checkox在一段时间，所以随意做出最终.. – simekadam

那么，如果我这样做最后...它给我奇怪的号码... 它只给我0或10 –

您可以使用下面：

listView.setOnItemClickListener(new OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, 
     int position, long id) { 
     Toast.makeText(getApplicationContext(), 
         "Click ListItem Number " + position, Toast.LENGTH_LONG) 
         .show(); 
    } 
});

或U可以保存位置标记checkbox和检查checkbox clicklistener

@Override 
     public View getView(int position, View convertView, ViewGroup parent) 
     { 
//   ur code... 

**cb.setTag(position);** 
      row.setOnClickListener(this); 
      return row; 
     } 


     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
**int position = v.getTag();** //cast & check for Tag not null too. 
      Toast toast = Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT); 
      toast.show(); 


     }

第一个选项，我试过了，它没有工作... 第二个选项并没有那么差:) –

都打瞌睡的工作，CheckBox是在第一个方法和方法的孩子的观点已经给你的位置 –

使用复选框setOnCheckedChangeListener e发泄。

尝试像这样...

CheckBox ChkBx = (CheckBox) findViewById(R.id.checkbox); 
ChkBx.setOnCheckedChangeListener(new OnCheckedChangeListener() 
{ 
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
    { 
    if (isChecked) 
    { 
     // perform logic 
    } 

    } 
});

是啊我知道如何使用它...它仍然dosnt给我我正在使用哪一行... 但tnx无论如何:) –

 @Override 
    public View getView(final int position, View convertView, ViewGroup parent) 
    { 
     // TODO Auto-generated method stub 
     View row = convertView; 
     if(row==null) 
     { // Object reuse 
      inflater = getLayoutInflater(); 
      row = inflater.inflate(R.layout.favorite_row, parent, false); 
     } 
     stationName1 = (TextView)row.findViewById(R.id.textFavoriteItemInRow); 
     stationName1.setText(stationNames[position]); 
     cb=(CheckBox)row.findViewById(R.id.cbCheck); 

     cb.setOnCheckedChangeListener(new CompoundButton. 
       OnCheckedChangeListener(){ 
       @Override 
       public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) { 
        if (isChecked) 
        { 
         cb.setChecked(isChecked); 
         Toast toast = Toast.makeText(getApplicationContext(), "checked" + position, Toast.LENGTH_SHORT); 
         toast.show(); 
        } 
        else 
        { 
         cb.setChecked(isChecked); 
         Toast toast = Toast.makeText(getApplicationContext(), "unChecked" + position, Toast.LENGTH_SHORT); 
         toast.show(); 
        } 
       } 
      }); 

     return row; 
    } 

}

这样做的工作吗？它应该..你可以从代码中删除'cb.setChecked（isChecked）;'.. – simekadam

以及它dosent ... 如果我删除该行，盒剂量检查在所有（没有V该框） –

看看这个简单的项目..它在那里工作https://github.com/simekadam/checkboxtest – simekadam
