Android登录注册功能封装
来源：互联网 发布：人工智能的基金有哪些 编辑：程序博客网 时间：2024/06/05 00:42
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。

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); } }public class MainActivity extends Activity { 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。
