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"};
    }
}
