Android listview和ListAdapter搭配使用，androidlistadapter

ListView時Android中內建的資料顯示控制項，要使用ListView填充資料，必須要通過適配器來填充，這裡給大家介紹一下ListAdapter適配器，如下：

java源碼：

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 自動產生的方法存根                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("歡迎您,"+i);        }        return list;    }}
