listView获得CheckBox 的位置

当一个lsitView中每个ietm有多个控件的时候想获得其中的位置，其实主要是item的位置

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
 
// grab view 
View v = convertView; 
// set view layout 
if (v == null) { 
    LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    v = vi.inflate(R.layout.layout_inbox_item, null); 
 
    CheckBox box = (CheckBox)v.findViewById(R.id.inbox_itemcheck); 
    if (box != null) { 
        box.setTag(position); //<-- sets the tag by its position 
        box.setOnCheckedChangeListener(new CheckBox.OnCheckedChangeListener() { 
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
                    int position = (Integer)buttonView.getTag(); //<-- get the position 
                } 
            }); 
    } 
} 
2.View getView(int position, View convertView, ViewGroup parent) { 
 
    // grab view 
    View v = convertView; 
    // set view layout 
    if (v == null) { 
        LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
        v = vi.inflate(R.layout.layout_inbox_item, null); 
 
        CheckBox box = (CheckBox)v.findViewById(R.id.inbox_itemcheck); 
        if (box != null) { 
            box.setOnCheckedChangeListener(new CheckBox.OnCheckedChangeListener() { 
                    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
                        ViewGroup v = (ViewGroup)buttonView.getParent().getParent(); 
                        int i = v.indexOfChild((View)buttonView.getParent()); 
                    } 
                }); 
        } 
    }
