三、User 用户数据的数据类型
1、用户数据
private String account=”未登录”;
private String password;
private String name=”没有名称”;
private String phone;
private String mail;

2、将账户名和密码数据输入User
public User (String account,String password)

3、get/set函数

public class User {    private  String account="未登录";    private  String password;    private  String name="没有名称";    private  String phone;    private  String mail;    private static String JSON_ACCOUNT="account";    private static String JSON_PASSWORD="password";    private static final String masterPassword = "FORYOU"; // AES加密算法的种子   public User (String account,String password){          this.account=account;          this.password=password;   }    public  String GetAccount(){ return account;}    public  String GetName(){return name;}    public  String GetMail(){ return mail;}    public  String GetPassword(){        return password;    }    public  String GetPhone(){        return phone;    }    public void SetAccount(String account){        this.account=account;    }    public void SetName(String name){        this.name=name;    }    public void SetMail(String mail){        this.mail=mail;    }    public void SetPassword(String password){        this.password=password;    }    public void SetPhone(String phone){        this.phone=phone;    }    public User(JSONObject json) throws Exception {        if (json.has(JSON_ACCOUNT)) {           account = json.getString(JSON_ACCOUNT);           password = json.getString(JSON_PASSWORD);        }    }    public JSONObject toJSON() throws Exception {        JSONObject json = new JSONObject();        try {            json.put(JSON_ACCOUNT, account);            json.put(JSON_PASSWORD, password);        } catch (JSONException e) {            e.printStackTrace();        }        return json;    }}

四、LoginUser implements View.OnClickListener, AdapterView.OnItemClickListener , PopupWindow.OnDismissListener
静态数据存储用户信息，与界面显示关联

1、用户数据
public static String account=”账户”;
public static String password=”密码”;
public static String name=”用户名”;
public static String phone=”电话”;
public static String mail=”邮箱”;

public class LoginUser {    public static String account="账户";    public static String password="密码";    public static String name="用户名";    public static String phone="电话";    public static String mail="邮箱";}

五、UserLoginSave 保存用户登录信息
1、保存用户登录信息列表
把User数据包装成JsonArray数组
public static void saveUserList(Context context, ArrayList<User> users)

2、获取用户登录信息列表
public static ArrayList<User> getUserList(Context context)

/** *保存用户登录信息 */public class UserLoginSave {    private static final String LOGIN_FILE="userinfo.json";    private static final String TAG="UserLoginSave";    /**     *  保存用户登录信息列表     *  把User数据包装成JsonArray数组     *  */    public static void saveUserList(Context context, ArrayList<User> users)           throws Exception {        Log.i(TAG, "正在保存");        Writer writer=null;        OutputStream out;        JSONArray array=new JSONArray();        for (User user:users){            array.put(user.toJSON());        }        try{            out=context.openFileOutput(LOGIN_FILE,Context.MODE_PRIVATE);//覆盖            writer=new OutputStreamWriter(out);            Log.i(TAG, "json的值:" + array.toString());            writer.write(array.toString());        }finally {            if (writer!=null){                writer.close();            }        }    }    /**     *  获取用户登录信息列表 */    public static ArrayList<User> getUserList(Context context){        /* 加载 */        FileInputStream in;        ArrayList<User> users=new ArrayList<User>();        try{            in=context.openFileInput(LOGIN_FILE);            BufferedReader reader = new BufferedReader(new InputStreamReader(in));                      StringBuilder jsonString = new StringBuilder();                      JSONArray jsonArray;                      String line;                      while ((line = reader.readLine()) != null) {                                jsonString.append(line);                    }                       Log.i(TAG, jsonString.toString());                       jsonArray = (JSONArray) new JSONTokener(jsonString.toString()).nextValue();                                // 把字符串转换成JSONArray对象                      for (int i = 0; i < jsonArray.length(); i++) {                               User user = new User(jsonArray.getJSONObject(i));                               users.add(user);                            }        }catch (FileNotFoundException e){            e.printStackTrace();        } catch (JSONException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        } catch (Exception e) {            e.printStackTrace();        }        return users;    }}
