Java代码的实现

变量定义

再将对象的属性进行封装，给每个属性设置getter/setter方法

public class Classinfo {
private String title1;
private String title2;
private String title3;
private String title4;

public Classinfo(String title1, String title2, String title3,String title4) {
    this.title1=title1;
    this.title2=title2;
    this.title3=title3;
    this.title4=title4;
}

创建Adapter，将数据加载到listview

    adapter = new SimpleAdapter(
            getActivity(),
            getData(),
            R.layout.activity_main,
            new String[]{"title1", "title2", "title3", "title4"},
            new int[]{R.id.title1, R.id.title2, R.id.title3, R.id.title4});
    ListView listView = (ListView)view.findViewById(R.id.list);
    listView.setAdapter(adapter);

添加listview的每个item的单击的监听事件

 @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
            String data = (String) adapterView.getItemAtPosition(position);

通过使用Map接口增加数据

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

    // 给list增加一条数据
    HashMap<String, Object> data = new HashMap<>();
    // Map映射添加数据
    data.put("title1", "蔡志坤");
    data.put("title2", "25");
    data.put("title3", "ffczk86@gmail.com");
    data.put("title4", "厦门市");
    // 将这个map放到list中
    datas.add(data);

    data = new HashMap<>();
    data.put("title1", "李杰华");
    data.put("title2", "25");
    data.put("title3", "aa@bb.com");
    data.put("title4", "漳州市");
    datas.add(data);

    data = new HashMap<>();
    data.put("title1", "张亮");
    data.put("title2", "25");
    data.put("title3", "cc@gmail.com");
    data.put("title4", "厦门市");
    datas.add(data);

    data = new HashMap<>();
    data.put("title1", "刘玄德");
    data.put("title2", "25");
    data.put("title3", "ffczk86@gmail.com");
    data.put("title4", "福州市");
    datas.add(data);

    return datas;
}
}

customerAdapter

public class CustomAdapter extends BaseAdapter {
private List dates;
private Context context;

//通过构造方法获取所需对象：上下文和数据
public CustomAdapter(Context context, List dates) {
    this.dates = dates;
    this.context = context;
}

@Override
public int getCount() {
    return dates.size();//一定返回list数据长度
}

@Override
public Object getItem(int i) {
    return dates.get(i);
}

@Override
public long getItemId(int i) {
    return i;
}

//自定义adapter重写getView（）方法
@Override
public View getView(int i, View view, ViewGroup parent) {
    //获取view
    if (view == null) {
        view = LayoutInflater.from(context).inflate(R.layout.activity_main, null);
    }//获取view中的每个控件对象
    TextView title1 = (TextView) view.findViewById(R.id.title1);
    TextView title2 = (TextView) view.findViewById(R.id.title2);
    TextView title3 = (TextView) view.findViewById(R.id.title3);
    TextView title4 = (TextView) view.findViewById(R.id.title4);

    //给每个view控件赋值
    Classinfo classInfo = datas.get(i);
    title1.setText(classinfo.gettitle1());
    title2.setText(classinfo.getTitle2());
    title3.setText(classinfo.gettitle3());
    title4.setText(classinfo.gettitle4());
    return null;
}

}
