Android如何获取ListView中被点击条目的值呢?
我的ListView如下：
姓名 学号 成绩
aaa 111 99
bbb 222 95
数据类型都是String型的，ListView中的数据都是通过SimpleAdapter绑定到上面的。
请问我想获取学号和成绩改怎么获取呢？

获取到点击的那一行，然后根据你listView里面怎样放进数据，那就怎样取出。

可以做一个数据相对应的pojo类 列如Student.java 设置姓名、学号、成绩私有属性的set、get方法，重写toString方法
public class ListViewTest extends Activity{
private ListView lv;
private List<Student> stus;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
stus=new ArrayList<Student>();
stus.add(new Student(1001,"zhangsan",20,85));
stus.add(new Student(1002,"lisi",21,87.5));
stus.add(new Student(1003,"wangwu",22,88));
stus.add(new Student(1004,"zhaoliu",20,75));
stus.add(new Student(1005,"qianqi",21,97.5));
stus.add(new Student(1006,"liuba",22,68));
setContentView(R.layout.list_view_test);
lv=(ListView)findViewById(R.id.list_view_01);
List<Map<String,Object>> data=new ArrayList<Map<String,Object>>();
for(int i=0;i<stus.size();i++){
Map<String,Object> map=new HashMap<String,Object>();
map.put("s_id", stus.get(i).getId());
map.put("s_name", stus.get(i).getName());
map.put("s_age", stus.get(i).getAge());
map.put("s_score", stus.get(i).getScore());
data.add(map);
}
SimpleAdapter adapter=new SimpleAdapter(this,data,R.layout.list_view_item_02,new String[]{"s_id","s_name","s_age","s_score"},new int[]{R.id.s_id_text_2,R.id.s_name_text_2,R.id.s_age_text_2,R.id.s_score_text_2});
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Intent it=new Intent(ListViewTest.this,StudentDescribeActivity.class);
it.putExtra("student", stus.get(arg2));
startActivity(it);
}
});
}
}
