        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {

         String selection = (String)parent.getItemAtPosition(pos);

         Log.i("id is "+v.getId(), selection, null);
         Toast.makeText(getApplicationContext(),"parent "+parent.getId()+"view "+v.getId()+" row "+rowindex, Toast.LENGTH_LONG).show();
        // TODO Auto-generated method stub


    }

我首先有两个AutocompleteTextviews是From＆amp;另一个是To。现在我必须通过在文本.ie源和目标中输入值来验证这两个字段！但是我无法获得当前选择textview的id .ie源或目的地!! 怎么实现这个？!!

onClick建议，＆＃34;长行指数＆＃34;是所选项目的ID。

如何从列表中选择的两个autocompletetextview中获取autocompletetextview的id？
