SimpleAdapter 继承了BaseAdapter，是一个封装好的类，我们只要在外部给他提供参数，他就可以完成内部实现，代码如下：

public class MainActivity extends Activity
{int[] p_w_picpathID ={ R.drawable.ic_launcher, R.drawable.ic_launcher1, R.drawable.ic_launcher2,R.drawable.ic_launcher3, R.drawable.ic_launcher4 };@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ListView listView = (ListView) findViewById(R.id.listView1);List<HashMap<String, Object>> data = new ArrayList<HashMap<String, Object>>();for (int i = 0; i < 5; i++){HashMap<String, Object> map = new HashMap<String, Object>();map.put("title", "title" + i);map.put("subtitle", "subtitle" + i);map.put("time", "time" + i);map.put("p_w_picpath", p_w_picpathID[i]);data.add(map);}String[] from ={ "title", "subtitle", "time", "p_w_picpath" };int[] to ={ R.id.textView1, R.id.textView2, R.id.textView3, R.id.p_w_picpathView1 };SimpleAdapter adapter = new SimpleAdapter(this, data,R.layout.listitem, from, to);listView.setAdapter(adapter);//       SimpleAdapter(Context context, List<? extends Map<String, ?>>// data, int resource, String[] from, int[] to)// 构造方法需要传人的参数（上下文， 装有Map的容器对象，子布局，map中的key值，与key要一一对应的控件资源ID）}@Overridepublic 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;}
}

这种格式简单，统一，适合用ArrayAdapter，数组适配器。

泛型可以是String类型，代码如下：

ArrayList<String> list = new ArrayList<String>();
for (int i = 0; i < 10; i++)
{list.add("title" + i);
}
//。。。。。。
ArrayAdapter adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,list);
//这里使用的是android sdk提供的simple_list_item_1子布局
listView.setAdapter(adapter);

以上也可以另一种方法实现，继承ListActivity，就不需要在onCreate()方法里setContentView(textView);

ArrayList<String> mData = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState)
{super.onCreate(savedInstanceState);for (int i = 0; i < 5; i++){mData.add("title" + i);}setListAdapter(new ArrayAdapter<String>(this,         android.R.layout.simple_list_item_1, mData));
}
