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

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);
}
}
