我有.getText错误

Question

我想点击列表视图，然后显示文字，但它有错误.getText

   ListView listView = getListView();
   listView.setTextFilterEnabled(true);

    listView.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

            Toast.makeText(getApplicationContext(),
                    ((TextView) view).findViewById(R.id.line_a).getText(), 
                    Toast.LENGTH_SHORT).show();
        }


              });

}
