在Android ListView中添加ItemListener

Question

我有一个旋转视图和4个选项卡，显示在我的第一个UI。我为每个Tabs添加了ListView。但是OnItemClickListener不是为ListFragment工作的。我的类是从ListFragment扩展而来的，实现了OnItemClickListener。我想要做的是，当我从列表中选择一个项目时，我必须显示Toast，它显示了我选择的项目的名称。但这不适合我。没有错误发生，但做不到事情。有人能帮我吗。我的完整代码如下：

import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class TUFragment extends ListFragment implements OnItemClickListener {

ListView list;
View rootView;

final String[] courses = new String[] { "BIM", "BBA", "BBS", "BSc-CSIT",
        "BSc-IT", "BHM", "BTTM", "MBA", "MBS", "MSc-IT", "MTTM" };

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    rootView = inflater.inflate(R.layout.fragment_tu, container, false);

    list = (ListView) rootView.findViewById(android.R.id.list);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
            android.R.layout.simple_list_item_1, courses);
    list.setAdapter(adapter);

    list.setOnItemClickListener(this);

    return rootView;
}

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
    Toast.makeText(this.getActivity(), "You have Selected: " + courses[arg2],
            Toast.LENGTH_LONG).show();
}
}

事先鸣谢

试试这个..。

，并更改为setListAdapter(adapter);。

@Override
public void onItemClick(AdapterView<?> arg0, View v, int arg2, long arg3) {
    String val = ((TextView) v).getText().toString().trim();
    Toast.makeText(getActivity(), "You have Selected: " + val,
            Toast.LENGTH_LONG).show();
}
