android开发 - ListView

android 中很多应用都是用ListView来显示数据


就像系统中的设置里面，每一行，就是构成的ListView

private ListView listview;

private PersonService person;

     @Override

     protected void onCreate(Bundle savedInstanceState) {

         super.onCreate(savedInstanceState);

         setContentView(R.layout.activity_main);

         

         person = new PersonService(this);

         

         listview = (ListView)this.findViewById(R.id.listview);

         show();

     }

     

     private void show(){

     
List<Person> list = person.getPageData(0, 20);

     
//以下使用适配器，来完成数据与控件的绑定

     
List<HashMap<String,Object>> data = new ArrayList<HashMap<String,Object>>();

     
for(Person person :list){

     
HashMap<String,Object> item = new HashMap<String,Object>();

     
item.put("name", person.getName());

     
item.put("phone", person.getPhone());

     
item.put("id", person.getId());

     
data.add(item);

     
}

     
SimpleAdapter adapter = 

     
new SimpleAdapter(this,data,R.layout.item,

     
new String[]{"name","phone","amount"},

     
new int[]{R.id.name,R.id.mobile,R.id.saveMoney});

     
listview.setAdapter(adapter);

     
 

     }
