Android實現(xiàn)登錄注冊功能封裝
更新時間：2017年01月06日 15:27:04 作者：xuejianxin268
Android應用軟件基本上都會用到登錄注冊功能，本篇文章主要介紹了Android登錄注冊功能封裝功能實現(xiàn)，具有一定的參考價值，有興趣的可以了解一下。
我們都知道Android應用軟件基本上都會用到登錄注冊功能，那么對一個一個好的登錄注冊模塊進行封裝就勢在必行了。這里給大家介紹一下我的第一個項目中所用到的登錄注冊功能的，已經(jīng)對其進行封裝，希望能對大家有幫助，如果有什么錯誤或者改進的話希望各位可以指出。
我們都知道登錄注冊系列功能的實現(xiàn)有以下幾步：
- 注冊賬號
- 登錄賬號 （第三方賬號登錄）
- 記住密碼
- 自動登錄
- 修改密碼
大體的流程如下
對于需要獲取用戶登錄狀態(tài)的操作，先判斷用戶是否已經(jīng)登錄。
如果用戶已經(jīng)登錄，則繼續(xù)后面的操作，否則，跳轉(zhuǎn)到登錄頁面進行登錄。
如果已經(jīng)有賬號，則可以直接登錄，或者可以直接選擇第三方平臺授權(quán)登錄。
如果還沒有賬號，則需要先進行賬號注冊，注冊成功后再登錄；也可以不注冊賬號，通過第三方平臺授權(quán)進行登錄。
如果有賬號，但忘記密碼，可以重置密碼，否則直接登錄。
好了，一個登錄注冊系列的常用功能就是以上這五點了，大體流程也已經(jīng)知道了，接下來讓我們一個一個的實現(xiàn)它們。
注冊功能的實現(xiàn)
注冊時一般通過手機或者郵箱來注冊，這里我選擇利用手機號來注冊；且注冊時通常需要接收驗證碼，這里通過第三方的Mob平臺的短信SDK來實現(xiàn)，第三方賬號授權(quán)也是利用Mob的ShareSDK來實現(xiàn)的。注冊完成后由客戶端將注冊信息提交至服務端進行注冊，提交方式為HTTP的POST請求方式。

登錄功能的實現(xiàn)
登錄功能需要在完成注冊以后才能進行，只要提交賬號、密碼等信息至服務器，請求登錄即可，至于第三方登錄功能利用Mob平臺的ShareSDK來實現(xiàn)。

忘記密碼功能實現(xiàn)
到這一步其實大家都應該明白了，我用的都是最簡單的方式去實現(xiàn)這些功能，就是通過提交數(shù)據(jù)給服務器，然后由服務器判斷提交的數(shù)據(jù)是否正確，正確的話就返回注冊信息，包含賬號、密碼等功能，然后對返回的數(shù)據(jù)進行操作，修改密碼功能也是這樣，修改返回數(shù)據(jù)中密碼并重新提交給服務器，這個功能就完成了。

記住密碼和自動登錄功能的實現(xiàn)
記住密碼和自動登錄功能可以通過SharedPreferences來實現(xiàn)
調(diào)用Context.getSharePreferences(String name, int mode)方法來得到SharePreferences接口，該方法的第一個參數(shù)是文件名稱，第二個參數(shù)是操作模式。
操作模式有三種：MODE_PRIVATE(私有) ,MODE_WORLD_READABLE(可讀),MODE_WORLD_WRITEABLE(可寫)
SharePreference提供了獲得數(shù)據(jù)的方法，如getString(String key,String defValue)等
調(diào)用SharePreferences的edit()方法返回 SharePreferences.Editor內(nèi)部接口，該接口提供了保存數(shù)據(jù)的方法如： putString(String key,String value)等,調(diào)用該接口的commit()方法可以將數(shù)據(jù)保存。
這一部分還沒有進行封裝，簡單的給大家介紹一下利用SharePreferences來實現(xiàn)記住密碼和自動登陸
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();
}
// 存放長整形值
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();
}
// 存放布爾型值
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();
}
// 清空記錄
public void clear() {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.clear();
editor.commit();
}
// 注銷用戶時清空用戶名和密碼
// 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();
// }
// 獲得用戶信息中某項字符串型的值
public String getStringInfo(String key) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
return sp.getString(key, "");
}
// 獲得用戶息中某項整形參數(shù)的值
public int getIntInfo(String key) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
return sp.getInt(key, -1);
}
// 獲得用戶信息中某項長整形參數(shù)的值
public Long getLongInfo(String key) {
SharedPreferences sp = context.getSharedPreferences(USER_INFO,
Context.MODE_PRIVATE);
return sp.getLong(key, -1);
}
// 獲得用戶信息中某項布爾型參數(shù)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);
// 判斷是否記住了密碼的 初始默認是要記住密碼的
if (userInfo.getBooleanInfo(ISSAVEPASS)) {
CK_save.setChecked(true);
usernameEdit.setText(userInfo.getStringInfo(USER_NAME));
passwordEdit.setText(userInfo.getStringInfo(PASSWORD));
// 判斷是否要自動登陸
if (userInfo.getBooleanInfo(AUTOLOGIN)) {
// 默認是要自動登陸的
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);
}
}
});
}
}
可見要實現(xiàn)記住密碼和自動登錄功能并不難，只要在登陸的XML布局文件添加兩個Checkbar并對其進行設置，然后在Activity中進行簡單的處理，就可以實現(xiàn)了。
