ListView和Adapter

这次的任务是使用ListView和Adapter完成列表信息显示，界面如图所示。

xml代码：

其效果图如下：

JAVA代码：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView=(ListView) findViewById(R.id.list);

adapter = new SimpleAdapter(this, getData(),
R.layout.list_item,
new String[]{"name", "age", "mail","address"},
new int[]{ R.id.name,R.id.age,R.id.mail,R.id.address});

listView=(ListView) findViewById(R.id.list);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
String data = (String) adapterView.getItemAtPosition(position);
}
});

}

private List<HashMap<String, Object>> getData() {
List<HashMap<String, Object>> datas = new ArrayList<>();

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

data.put("name", "姓名：蔡志坤");
data.put("age","年龄：25");
data.put("mail", "邮箱：ffczk86@gmail.com");
data.put("address","地址：厦门");

datas.add(data);

data = new HashMap<>();
data.put("name", "姓名：李华杰");
data.put("age","年龄：25");
data.put("mail", "邮箱：aa@bb.com");
data.put("address","地址：漳州");
datas.add(data);

data = new HashMap<>();
data.put("name", "姓名:张亮");
data.put("age","年龄：25");
data.put("mail", "邮箱：cc@gmail.com");
data.put("address","地址：厦门");
datas.add(data);

data = new HashMap<>();
data.put("name", "姓名：陈旭");
data.put("age","年龄：25");
data.put("mail", "邮箱：ccadd@gmail.com");
data.put("address","地址：厦门");
datas.add(data);

data = new HashMap<>();
data.put("name", "姓名：刘玄德");
data.put("age","年龄：25");
data.put("mail", "邮箱：ffczk@gmail.com");
data.put("address","地址：福州");
datas.add(data);

return datas;
也就差不多完成了。
