我们都知道Android应用软件基本上都会用到登录注册功能，那么对一个一个好的登录注册模块进行封装就势在必行了。这里给大家介绍一下我的第一个项目中所用到的登录注册功能的，已经对其进行封装，希望能对大家有帮助，如果有什么错误或者改进的话希望各位可以指出。
我们都知道登录注册系列功能的实现有以下几步：
- 注册账号
- 登录账号 （第三方账号登录）
- 记住密码
- 自动登录
- 修改密码
大体的流程如下
-
对于需要获取用户登录状态的操作，先判断用户是否已经登录。
-
如果用户已经登录，则继续后面的操作，否则，跳转到登录页面进行登录。
-
如果已经有账号，则可以直接登录，或者可以直接选择第三方平台授权登录。
-
如果还没有账号，则需要先进行账号注册，注册成功后再登录；也可以不注册账号，通过第三方平台授权进行登录。
-
如果有账号，但忘记密码，可以重置密码，否则直接登录。
好了，一个登录注册系列的常用功能就是以上这五点了，大体流程也已经知道了，接下来让我们一个一个的实现它们。
注册功能的实现
注册时一般通过手机或者邮箱来注册，这里我选择利用手机号来注册；且注册时通常需要接收验证码，这里通过第三方的Mob平台的短信SDK来实现，第三方账号授权也是利用Mob的ShareSDK来实现的。注册完成后由客户端将注册信息提交至服务端进行注册，提交方式为HTTP的POST请求方式。

登录功能的实现
登录功能需要在完成注册以后才能进行，只要提交账号、密码等信息至服务器，请求登录即可，至于第三方登录功能利用Mob平台的ShareSDK来实现。

忘记密码功能实现
到这一步其实大家都应该明白了，我用的都是最简单的方式去实现这些功能，就是通过提交数据给服务器，然后由服务器判断提交的数据是否正确，正确的话就返回注册信息，包含账号、密码等功能，然后对返回的数据进行操作，修改密码功能也是这样，修改返回数据中密码并重新提交给服务器，这个功能就完成了。

记住密码和自动登录功能的实现
记住密码和自动登录功能可以通过SharedPreferences来实现
调用Context.getSharePreferences(String name, int mode)方法来得到SharePreferences接口，该方法的第一个参数是文件名称，第二个参数是操作模式。
操作模式有三种：MODE_PRIVATE(私有) ,MODE_WORLD_READABLE(可读),MODE_WORLD_WRITEABLE(可写)
SharePreference提供了获得数据的方法，如getString(String key,String defValue)等
调用SharePreferences的edit()方法返回 SharePreferences.Editor内部接口，该接口提供了保存数据的方法如： putString(String key,String value)等,调用该接口的commit()方法可以将数据保存。
这一部分还没有进行封装，简单的给大家介绍一下利用SharePreferences来实现记住密码和自动登陆
代码
import android.content.Context;
import android.content.SharedPreferences;
public class UserInfo {
private String USER_INFO = "userInfo";
private Context context;
public UserInfo() {
}
public UserInfo(Context context) {
this.context = context;
}
// 存放字符串型的值
public void setUserInfo(String key, String value) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.remove(key);
editor.putString(key, value);
editor.commit();
}
// 存放整形的值
public void setUserInfo(String key, int value) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.remove(key);
editor.putInt(key, value);
editor.commit();
}
// 存放长整形值
public void setUserInfo(String key, Long value) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.remove(key);
editor.putLong(key, value);
editor.commit();
}
// 存放布尔型值
public void setUserInfo(String key, Boolean value) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.remove(key);
editor.putBoolean(key, value);
editor.commit();
}
// 清空记录
public void clear() {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.clear();
editor.commit();
}
// 注销用户时清空用户名和密码
// public void logOut() {
// SharedPreferences sp = context.getSharedPreferences(USER_INFO,
// Context.MODE_PRIVATE);
// SharedPreferences.Editor editor = sp.edit();
// editor.remove(ACCOUNT);
// editor.remove(PASSWORD);
// editor.commit();
// }
// 获得用户信息中某项字符串型的值
public String getStringInfo(String key) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
return sp.getString(key, "");
}
// 获得用户息中某项整形参数的值
public int getIntInfo(String key) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
return sp.getInt(key, -1);
}
// 获得用户信息中某项长整形参数的值
public Long getLongInfo(String key) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
return sp.getLong(key, -1);
}
// 获得用户信息中某项布尔型参数的值
public boolean getBooleanInfo(String key) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
return sp.getBoolean(key, false);
}
}
private Button login, cancel;
private EditText usernameEdit, passwordEdit;
private CheckBox CK_save, CK_auto;
private UserInfo userInfo;
private static final String USER_NAME = "user_name";
private static final String PASSWORD = "password";
private static final String ISSAVEPASS = "savePassWord";
private String username;
private String password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
userInfo = new UserInfo(this);
login = (Button) findViewById(R.id.login_btn);
cancel = (Button) findViewById(R.id.unlogin_btn);
usernameEdit = (EditText) findViewById(R.id.username);
passwordEdit = (EditText) findViewById(R.id.password);
CK_save = (CheckBox) findViewById(R.id.savePassword);
CK_auto = (CheckBox) findViewById(R.id.autoLogin);
// 判断是否记住了密码的 初始默认是要记住密码的
if (userInfo.getBooleanInfo(ISSAVEPASS)) {
CK_save.setChecked(true);
usernameEdit.setText(userInfo.getStringInfo(USER_NAME));
passwordEdit.setText(userInfo.getStringInfo(PASSWORD));
// 判断是否要自动登陆
if (userInfo.getBooleanInfo(AUTOLOGIN)) {
// 默认是要自动登陆的
CK_auto.setChecked(true);
Intent i = new Intent();
i.setClass(MainActivity.this, SecondActivity.class);
startActivity(i);
}
}
login.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
username = usernameEdit.getText().toString();
password = passwordEdit.getText().toString();
if (username.equals("liang") && password.equals("123")) {
if (CK_save.isChecked()) {
userInfo.setUserInfo(USER_NAME, username);
userInfo.setUserInfo(PASSWORD, password);
userInfo.setUserInfo(ISSAVEPASS, true);
}
if (CK_auto.isChecked()) {
userInfo.setUserInfo(AUTOLOGIN, true);
}
Intent i = new Intent();
i.setClass(MainActivity.this, SecondActivity.class);
startActivity(i);
}
}
});
}
}
可见要实现记住密码和自动登录功能并不难，只要在登陆的XML布局文件添加两个Checkbar并对其进行设置，然后在Activity中进行简单的处理，就可以实现了。
