sim_adapter=new SimpleAdapter(context, data, resource, from, to);
-
context:上下文；
-
data：需要展示的数据源，是map组成的list集合，每个Map对应ListView中的一行，每一个Map（键——值对）中的键名必须包含在from中所指定的键；
-
resource：展示的布局文件，可以自己在layout设置xml文件去设置需要展示 的样式；
-
from：Map中的键名；
-
to：绑定数据视图的ID，与from成对应的关系。
public class MainActivity extends Activity {
private ListView listView;
private SimpleAdapter simple_adapter;
private List< Map<String, Object>> dataList ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView=(ListView) findViewById(R.id.listView);
dataList=new ArrayList< Map<String, Object>>();
//适配器设置
simple_adapter=new SimpleAdapter(this, getData(), R.layout.item, new
String[] {"pic","text"}, new int[] {R.id.pic,R.id.text});
//启用适配器
listView.setAdapter(simple_adapter);
}
// 设置数据源
private List<Map<String, Object>> getData() {
for(int i=0;i<20;i++) {
Map map=new HashMap<String, Object>();
map.put("pic", R.drawable.ic_launcher);
map.put("text", "慕课网"+i);
dataList.add(map);
}
return dataList;
};
}
运行结果：
如果需要对每个Map进行监听，则可以设置implement OnItemClickListener接口进行监听，但别忘记加载监听器！
public class MainActivity extends ActionBarActivity implements OnItemClickListener{
private GridView grid;
private SimpleAdapter sim_adapter;
private List<Map<String, Object>> list;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
grid = (GridView) findViewById(R.id.gridView1);
list=new ArrayList();
sim_adapter = new SimpleAdapter(this, getData(), R.layout.item, new String[] { "pic", "text" },
new int[] { R.id.image, R.id.text });
grid.setAdapter(sim_adapter);
grid.setOnItemClickListener(this); //加载监听器
}
private List<Map<String, Object>> getData() {
for (int i = 0; i < 10; i++) {
Map<String, Object> map = new HashMap<String, Object>();
map.put("pic", R.drawable.ic_launcher);
map.put("text", "app" + (i + 1));
list.add(map);
}
return list;
// TODO Auto-generated method stub
}
//实现监听，加载动作
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) {
Toast.makeText(this, "这是第"+(position+1)+"个应用", Toast.LENGTH_SHORT).show();
}
}
