如何获取列表视图的选定项目以共享特定文本？

这是我的代码，我试过这个，但它没有用

public class MainActivity extends ListActivity {

TextView content;
ListView list;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // list = (ListView) findViewById(R.id.list1);
    content = (TextView) findViewById(R.id.output);

    // listView = (ListView) findViewById(R.id.list);
    String[] values = new String[] { "Android Example ListActivity",
            "Adapter implementation", "Simple List View With ListActivity",
            "ListActivity Android", "Android Example",
            "ListActivity Source Code",
            "ListView ListActivity Array Adapter",
            "Android Example ListActivity" };


    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, values);

    // Assign adapter to List
    setListAdapter(adapter);

}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {

    super.onListItemClick(l, v, position, id);

    // ListView Clicked item index
    int itemPosition = position;

    // ListView Clicked item value
    String itemValue = (String) l.getItemAtPosition(position);

    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");

    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
            "Subject Here");
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, itemValue);
    startActivity(Intent.createChooser(sharingIntent, "Share via"));

}

}

您需要实施list.setOnItemClickListener(new OnItemClickListener())并根据ArrayList or Array ListItem从ListItem获取特定position的值，例如：

list.setOnItemClickListener(new OnItemClickListener() {

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

             String txt = text.getText().toString();
            Intent sharingIntent = new Intent(
                    android.content.Intent.ACTION_SEND);
            sharingIntent.setType("text/plain");
            String shareBody = "Here is the share content body";
            sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
                    "Subject Here");
            sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, yourarraylist.get(position));
            startActivity(Intent.createChooser(sharingIntent, "Share via"));

        }

    });
