java - 我的 listview 代码有什么问题？

Question

我一直在使用 The Android Developer's CookBook 来学习 android listview。这是我的代码:

package com.mavenmaverick.listviewtest;

import android.app.ListActivity;
import android.widget.ListView;

public class ActivityExample extends ListActivity{

static final String[] CHOICES = new String[]{

    "Activity 1",
    "Activity 2",
    "Activity 3",
};

setListAdapter(new ArrayAdapter<String>(this, android.R.listView1, CHOICES))    
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
getListView().setTextFilterEnabled(true);
}

}

我一直在关注书中的内容，但在 setListAdapter 上出现错误说Syntax error on token "setListAdapter", @ expected before this token和 getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);说Syntax error on token ".", { expected .即使遵循 eclipse 给出的建议，错误似乎也在增加。请帮忙。

尝试这个..

     package com.mavenmaverick.listviewtest;

     import android.app.ListActivity;
     import android.widget.ListView;

     public class ActivityExample extends ListActivity{

          static final String[] CHOICES = new String[]{

                 "Activity 1",
                 "Activity 2",
                 "Activity 3"
          };

     @Override
     protected void onCreate(Bundle savedInstanceState) {                    
             super.onCreate(savedInstanceState);

          setListAdapter(new ArrayAdapter<String>(new ArrayAdapter<String>(this,
                            android.R.layout.simple_list_item_1,CHOICES));   
          getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
          getListView().setTextFilterEnabled(true);
     }
}
