如何从ListView中的string ArrayAdapter中获取文本值？

Question

在程序中有两个 activity，第一个，列表视图的链接到html文件；第二个是一个 webview。例如，当我点击 listview 中的"First Topic" ，就会打开 webview中的 "1.html"。
我想获得 listview 中点击元素的 text值，再用下面的方法显示在第二个activity中的textview中：

TextView title = (TextView) findViewById(R.id.app_name);
title.setText(getString(R.string.app_name));

ListViewActivity 代码:

public class ListViewActivity extends Activity implements OnClickListener {
    private ListView lv1;
    private String lv_arr[] = { "First Topic", "Second Topic" };
        /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.list);
         lv1 = (ListView) findViewById(R.id.listView);
        lv1.setAdapter(new ArrayAdapter<String>(this, R.layout.list_items,
                lv_arr));
        lv1.setTextFilterEnabled(true);
        lv1.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> a, View v, int position,
                    long id) {
                String itemname = new Integer(position).toString();
                Intent intent = new Intent();
                intent.setClass(ListViewActivity.this, WebViewActivity.class);
                  Bundle b = new Bundle();
                b.putString("defStrID", itemname);
                intent.putExtras(b);
                 startActivity(intent);
            }
        });
    }
}

如何把 listview 中点击的值传递到 webview activity?

  public void onItemClick(AdapterView<?> a, View v, int position,
                    long id) {
                String itemname = ((TextView)v).getText().toString(); //这里应该是这样的
                Intent intent = new Intent();
                intent.setClass(ListViewActivity.this, WebViewActivity.class);
                  Bundle b = new Bundle();
                b.putString("defStrID", itemname);
                intent.putExtras(b);
                 startActivity(intent);
            }
