如何从listView上的选定项中提取文本 [英] How to extract the text from the selected item on the listView

问题描述

我有一个包含一些项目的列表视图.我想从所选项目中获取文本.

I have a listview with some items. I would like to get the text from the selected item.

这是我的列表适配器和 onItemClickListener:

Here is my list adapter and the onItemClickListener:

ListView lv = (ListView)findViewById(R.id.listView1);
    lv.setAdapter(new ArrayAdapter<Country>(
            this,R.layout.list_black_text,R.id.list_content, values));


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

你能告诉我如何从所选项目中获取字符串.

Could you tell me please how to get the String from the selected item.

方法 ((TextView) view).getText() 不起作用，我有一个

the method ((TextView) view).getText() does not work, i have a

ClassCastException: android.widget.LinearLayout

我找到了解决方案，也许有人会需要它:

I have found the solution, maybe somebody will need it:

ListView lv = (ListView)findViewById(R.id.listView1);
    lv.setAdapter(new ArrayAdapter<Country>(
            this,R.layout.list_black_text,R.id.list_content, values));

    lv.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
            TextView textView = (TextView) view.findViewById(R.id.list_content);
            String text = textView.getText().toString(); 
            System.out.println("Choosen Country = : " + text);

    }});

推荐答案

使用这个:

String selectedFromList = (String) (lv.getItemAtPosition(position));

无论列表中的数据类型是什么，都要进行相应的转换.

Whatever the datatype you are having in your list, cast accordingly.
