android listview 三种适配器设置

1：

public class ArrayAdapterActivity extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //列表项的数据
        String[] strs = {"1","2","3","4","5"};
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,strs);
        setListAdapter(adapter);
    }
}

2：

xml

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     >
 <ImageView
     android:id="@+id/img"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_margin="5dp"
     />
 <TextView
     android:id="@+id/title"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:textColor="#ffffff"
     android:textSize="20sp"
     />
 </LinearLayout>

代码

 public class SimpleAdapterActivity extends ListActivity {
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         SimpleAdapter adapter = new SimpleAdapter(this, getData(), R.layout.simple, new String[] { "title",  "img" }, new int[] { R.id.title, R.id.img });
         setListAdapter(adapter);
     }

     private List<Map<String, Object>> getData() {
         //map.put(参数名字,参数值)
         List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
         Map<String, Object> map = new HashMap<String, Object>();
         map.put("title", "摩托罗拉");
         map.put("img", R.drawable.icon);
         list.add(map);

         map = new HashMap<String, Object>();
         map.put("title", "诺基亚");
         map.put("img", R.drawable.icon);
         list.add(map);

         map = new HashMap<String, Object>();
         map.put("title", "三星");
         map.put("img", R.drawable.icon);
         list.add(map);
         return list;
         }
 }

3：

public class SimpleCursorAdapterActivity extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //获得一个指向系统通讯录数据库的Cursor对象获得数据来源
        Cursor cur = getContentResolver().query(People.CONTENT_URI, null, null, null, null);
        startManagingCursor(cur);
        //实例化列表适配器

        ListAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1, cur, new String[] {People.NAME}, new int[] {android.R.id.text1});
        setListAdapter(adapter);
    }
}
