我有一个列表视图，其中有四到五列。列表视图的值是通过数据库查询分配的。列表视图是使用 SimpleCursorAdapter 创建的。我正在尝试获取列表视图第一列的值......但我无法检索它。我怎么做？？？这是我的自定义适配器

private class MyCursorAdapter extends SimpleCursorAdapter
{

    @SuppressWarnings("deprecation")
    public MyCursorAdapter(Context context, int layout, Cursor c,
            String[] from, int[] to,int flags) {
        super(context, layout, c, from, to);
        // TODO Auto-generated constructor stub
    }

     @Override 
      public View getView(int position, View convertView, ViewGroup parent) { 

       //get reference to the row
       View view = super.getView(position, convertView, parent);
       //check for odd or even to set alternate colors to the row background
       if(position % 2 == 0){ 
        view.setBackgroundColor(Color.rgb(238, 233, 233));
       }
       else {
        view.setBackgroundColor(Color.rgb(255, 255, 255));
       }
       return view; 
      } 


}

这是我将适配器分配给列表视图的地方

MyCursorAdapter myDataAdapter=new MyCursorAdapter(this,R.layout.list_row_layout,cursor, columns, to, 0);

    listView=(ListView)findViewById(R.id.listView1);

    listView.addHeaderView(getLayoutInflater().inflate(R.layout.list_header, null, false));

    listView.setAdapter(myDataAdapter);

这是 onclick 监听器

listView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int position,
                long arg3) {
            // TODO Auto-generated method stub
            //View view= 
            String ttsl_can=(( listView.getItemAtPosition(position).toString()));
            Toast.makeText(PendingActivity.this, ttsl_can, Toast.LENGTH_LONG).show();
        }
    });

通过单击列表视图 m 的特定行，得到响应为android.database.SQLiteCursor@40d2f13d

我如何将响应作为我单击的任何行的第一列的值？我在我的代码中做了什么改变来实现这一点？？？

请帮忙！！提前致谢！！

试试这样：

    listView.setOnItemClickListener(new OnItemClickListener() {

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

            Cursor cursor = listView.getItemAtPosition(position);

            // Here you have to getString using index
            String str = cursor.getString(<you column index>);

            Toast.makeText(PendingActivity.this, str, Toast.LENGTH_LONG).show();
        }
    });
