列表视图:获取所选行的文本

Question

我有一个listview图像和textview每行一个.我希望在点击整行时获得文本的值.下面的代码表现得很奇怪.我得到的是随机行的值,而不是点击的那一行.

我没有弄错.任何帮助,将不胜感激.

我这样做,:

public static class LazyAdapter extends BaseAdapter {

    private Activity activity;
    private ArrayList<HashMap<String, String>> data;
    private static LayoutInflater inflater=null;
    public ImageLoader imageLoader; 

    public LazyAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
        activity = a;
        data=d;
        inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        imageLoader=new ImageLoader(activity.getApplicationContext());
    }

    public int getCount() {
        return data.size();
    }

    public Object getItem(int position) {
        return position;
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {
        View vi=convertView;
        if(convertView==null)
            vi = inflater.inflate(R.layout.list_row, null);

        title = (TextView)vi.findViewById(R.id.title); // title
        ImageView thumb_image=(ImageView)vi.findViewById(R.id.list_image); // thumb image

        HashMap<String, String> song = new HashMap<String, String>();
        song = data.get(position);

        // Setting all values in listview
        title.setText(song.get(Meida_listActivity.KEY_TITLE));
        imageLoader.DisplayImage(song.get(Meida_listActivity.KEY_THUMB_URL), thumb_image);


        vi.setOnClickListener( new View.OnClickListener()
        {


            public void onClick(View v)
            {
                  String listValue = (String) title.getText();
                  System.out.println("this is value of string ::: :::: " + listValue);

            }


        });
        return vi;
    }
}

您也可以尝试实现click for listview并获得这样的文本!希望它有效..

listView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            TextView text = (TextView) view.findViewById(R.id.title);
            String lst_txt = text.getText().toString().trim();
            System.out.println("this is value of string ::: :::: " + lst_txt);
        }
    });
