ListView实现简单列表

效果图：

啥也没干的ListView张这样：

fry.Activity01

 package fry;

 import com.example.ListView.R;

 import android.app.Activity;
 import android.os.Bundle;
 import android.view.View;
 import android.widget.AdapterView;
 import android.widget.AdapterView.OnItemClickListener;
 import android.widget.ArrayAdapter;
 import android.widget.ListView;
 import android.widget.Toast;

 public class Activity01 extends Activity implements OnItemClickListener{
     private ListView listView;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         // TODO Auto-generated method stub
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity01);
         listView=(ListView) findViewById(R.id.listView);
         ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, getData());
         listView.setAdapter(adapter);
         listView.setOnItemClickListener(this);
     }
     @Override
     public void onItemClick(AdapterView<?> parent, View view, int position,
             long id) {
         // TODO Auto-generated method stub
         String string=(String) parent.getItemAtPosition(position);

         Toast.makeText(this, string, Toast.LENGTH_SHORT).show();
     }

     private String[] getData(){
         return new String[]{"韩寒","蔡静","卢本伟","五五开","战狼2","朝阳兄","虹桥一姐","犀利哥","王宝庆",
                 "系大大","搞踹踹","张三","李四","王五"};
     }
 }
