Android listview和ListAdapter搭配使用

ListView时Android中自带的数据显示控件，要使用ListView填充数据，必须要通过适配器来填充，这里给大家介绍一下ListAdapter适配器，效果图如下：

java源码：

package com.example.listview1;

import java.util.ArrayList;
import java.util.List;

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

public class MainActivity extends Activity {

    private ListView listview;
    private ListAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        listview=(ListView) findViewById(R.id.listView1);
        listview.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        adapter=new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_single_choice,getsource());
        listview.setAdapter(adapter);
        listview.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                // TODO 自动生成的方法存根
                Toast.makeText(MainActivity.this, ">>"+adapter.getItem(arg2),1).show();
            }
        });
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
    
    public List<String> getsource()
    {
        List<String> list=new ArrayList<String>();
        for(int i=0;i<20;i++)
        {
            list.add("欢迎您,"+i);
        }
        return list;
    }
}
