Android使用Kotlin封装Google等海外登录工具类
前言：
之前由于项目做国际化，所以需要接入Google、FaceBook、Twitter等各种第三方登录的Api，于是查找官网资料，申请各种key和密钥，最后成功完成了这三个第三方登录Api的功能，但是由于很多地方需要调用，前期做得很粗糙，发现调用很麻烦，于是做了一次封装，总结一下,关于资料的申请这里就不说了.如果是海外或者有vpn的小伙伴可以集成各种key后直接测试，国内你懂的. 本文采用的是Kotlin语法，直接上封装的代码：
1.配置google依赖：
arduino
// google
"play-services-auth" : 'com.google.android.gms:play-services-auth:19.0.0',
"play-services-wallet" : 'com.google.android.gms:play-services-wallet:18.1.2',
"play-services-base" : 'com.google.android.gms:play-services-base:17.6.0',
"play-services-analytics" : 'com.google.android.gms:play-services-analytics:17.0.0',
"google-pay" : 'com.android.billingclient:billing:4.0.0',
"google-ar" : 'com.google.ar:core:1.11.0',
2.配置FaceBook:
arduino
// Facebook Core only (Analytics)
"facebook-core" : 'com.facebook.android:facebook-core:8.1.0',
// Facebook Login only
"facebook-login" : 'com.facebook.android:facebook-login:8.1.0',
// Facebook Share only
"facebook-share" : 'com.facebook.android:facebook-share:8.1.0',
// Facebook Messenger only
"facebook-messenger" : 'com.facebook.android:facebook-messenger:8.1.0',
// Facebook App Links only
"facebook-applinks" : 'com.facebook.android:facebook-applinks:8.1.0',
// Facebook Android SDK (everything)
"facebook-android-sdk" : 'com.facebook.android:facebook-android-sdk:8.1.0',
3.配置Twitter:
arduino
//twitter
"twitter" : 'com.twitter.sdk.android:twitter:3.3.0',
"tweet-composer" : 'com.twitter.sdk.android:tweet-composer:3.3.0',
"colorfulText" : 'org.zhx.common:colorfulText:1.0.0'
4.在build.gradle导入依赖：
php
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.6.0'
implementation 'androidx.appcompat:appcompat:1.3.1'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
api rootProject.ext.dependencies["facebook-login"]
api rootProject.ext.dependencies["facebook-core"]
api rootProject.ext.dependencies["play-services-auth"]
api rootProject.ext.dependencies["play-services-wallet"]
api rootProject.ext.dependencies["twitter"]
api rootProject.ext.dependencies["tweet-composer"]
}
5.接入Google、Facebook、Twitter:
Google、Facebook、Twitter之前需要安装Google服务，所以首先需要判断用户是否安装Google服务插件，这里说特别说明一下，一定要安装官网的正版Google服务插件，要不然会出现各种问题，这里就不展开了.检测用户是否安装Google服务的方法如下:
kotlin
/**
* 检查用户是否安装Google Play 服务
*/
open fun onCheckGooglePlayService(activity:Activity,code:Int){
// 验证是否已在此设备上安装并启用Google Play服务，以及此设备上安装的旧版本是否为此客户端所需的版本
GoogleApiAvailability.getInstance().makeGooglePlayServicesAvailable(activity)
/**
* 通过isUserResolvableError来确定是否可以通过用户操作解决错误
*/
if (GoogleApiAvailability.getInstance().isUserResolvableError(code)) {
GoogleApiAvailability.getInstance().getErrorDialog(activity, code, 200).show()
}
fun checkGooglePlayServiceExist(activity: Activity): Int {
return GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(activity)
}
6.Google登录工具类的封装：
kotlin
/**
* @author: njb
* @date: 2021/5/8 14:37
* @desc: Google登录工具类
*/
open class GoogleLoginUtils(private val activity: Activity, var listener: GoogleSignListener) {
var requestCode = 10
private var mGoogleSignInClient: GoogleSignInClient? = null
private var googleSignListener: GoogleSignListener? = null
init {
//初始化谷歌登录服务
val gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build()
mGoogleSignInClient = GoogleSignIn.getClient(activity, gso)
}
/**
* 登录
*/
open fun signIn() {
val signInIntent: Intent = mGoogleSignInClient!!.signInIntent
activity.startActivityForResult(signInIntent, requestCode)
}
/**
* 退出登录
*/
open fun signOut() {
}
fun handleSignInResult(completedTask: Task<GoogleSignInAccount>) {
try {
val account: GoogleSignInAccount? = completedTask.getResult(ApiException::class.java)
val status: Task<GoogleSignInAccount> = completedTask
if (status.isSuccessful) {
if (account != null) {
//ToastUtils.showShort(activity.getString(R.string.login_success))
googleSignListener?.googleLoginSuccess(account)
LogUtils.d("account" + account?.account)
} else {
googleSignListener?.googleLoginFail(activity.getString(R.string.login_failed))
}
}
} catch (e: ApiException) {
LogUtils.d("signInResult:failed code=" + e.statusCode)
}
}
open fun setGoogleSignListener(googleSignListener: GoogleSignListener?) {
this.googleSignListener = googleSignListener
}
interface GoogleSignListener {
fun googleLoginSuccess(account: GoogleSignInAccount)
fun googleLoginFail(message: String?)
fun googleLogoutSuccess()
fun googleLogoutFail()
}
/**
* 检查 Google Play 服务
*/
open fun onCheckGooglePlayServices(activity: Activity, code: Int) {
// 验证是否已在此设备上安装并启用Google Play服务，以及此设备上安装的旧版本是否为此客户端所需的版本
GoogleApiAvailability.getInstance().makeGooglePlayServicesAvailable(activity)
/**
* 通过isUserResolvableError来确定是否可以通过用户操作解决错误
*/
if (GoogleApiAvailability.getInstance().isUserResolvableError(code)) {
GoogleApiAvailability.getInstance().getErrorDialog(activity, code, 200).show()
}
}
fun checkGooglePlayServiceExist(activity: Activity): Int {
return GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(activity)
}
}
7.FaceBook登录工具类的封装：
kotlin
/**
*@author: njb
*@date: 2021/5/8 14:26
*@desc: FaceBook登录工具类
*/
open class FacebookLoginUtils(private val activity: Activity) {
private var loginManager: LoginManager? = null
private val permissions: List<String>
private var callbackManager: CallbackManager? = null
private var requestSuccessCode = 2896
private var requestCancelCode = 2897
private var requestFailedCode = 2898
private var mFaceBookLoginListener: FaceBookLoginListener? = null
var infoBean: FaceLoginInfoBean? = null
init {
//初始化facebook登录服务
callbackManager = CallbackManager.Factory.create()
getLoginManager().registerCallback(callbackManager, object : FacebookCallback<LoginResult> {
override fun onSuccess(result: LoginResult?) {
activity.setResult(requestSuccessCode)
getLoginInfo(result?.accessToken)
}
override fun onCancel() {
activity.setResult(requestCancelCode)
mFaceBookLoginListener?.onLoginCancel(activity.getString(R.string.login_cancel))
}
override fun onError(error: FacebookException?) {
activity.setResult(requestFailedCode)
mFaceBookLoginListener?.onLoginFail(error?.message)
LogUtils.d(error?.message)
}
})
permissions = listOf("email", "user_likes", "user_status", "user_photos", "user_birthday", "public_profile", "user_friends");
}
/**
* 登陆
*/
fun login() {
getLoginManager().logIn(activity, permissions)
}
/**
* 退出登陆
*/
fun loginOut() {
var logout = activity.resources.getString(R.string.com_facebook_loginview_log_out_action)
var cancel = activity.resources.getString(R.string.com_facebook_loginview_cancel_action)
val message: String
val profile: Profile = Profile.getCurrentProfile()
message = if (profile?.name != null) {
java.lang.String.format(
activity.resources.getString(
R.string.com_facebook_loginview_logged_in_as),
profile.name)
} else {
activity.resources.getString(
R.string.com_facebook_loginview_logged_in_using_facebook)
}
val builder: AlertDialog.Builder = AlertDialog.Builder(activity)
builder.setMessage(message)
.setCancelable(true)
.setPositiveButton(logout) { _, _ ->
getLoginManager().logOut()
}
.setNegativeButton(cancel, null)
builder.create().show()
}
/**
* 获取登录信息
* @param accessToken
*/
private fun getLoginInfo(accessToken: AccessToken?) {
var request = GraphRequest.newMeRequest(accessToken, object : GraphRequest.GraphJSONObjectCallback {
override fun onCompleted(`object`: JSONObject?, response: GraphResponse?) {
`object`?.run {
val id = optString("id") //比如:13813813888
val name = optString("name") //比如：Zhang San
val gender = optString("gender") //性别：比如 male （男） female （女）
val email = optString("email") //邮箱：比如：11111@qq.com
//获取用户头像
val object_pic = optJSONObject("picture")
val object_data = object_pic.optJSONObject("data")
val photo = object_data.optString("url")
//获取地域信息
val locale = optString("locale") //zh_CN 代表中文简体
infoBean = FaceLoginInfoBean()
infoBean?.id = id
infoBean?.name = name
infoBean?.email = email
infoBean?.gender = gender
infoBean?.picture = object_pic.toString()
infoBean?.data = object_data.toString()
infoBean?.photo = photo
infoBean?.locale = locale
infoBean?.let { mFaceBookLoginListener?.onLoginSuccess(it) }
}
}
})
val parameters = Bundle()
parameters.putString("fields", "id,name,link,gender,birthday,email,picture,locale,updated_time,timezone,age_range,first_name,last_name")
request.parameters = parameters
request.executeAsync()
}
fun getCallbackManager(): CallbackManager? {
return callbackManager
}
/**
* 获取loginMananger
* @return
*/
private fun getLoginManager(): LoginManager {
if (loginManager == null) {
loginManager = LoginManager.getInstance();
}
return loginManager!!
}
companion object {
/**
* 是否处在登陆状态
*/
fun isLogin(): Boolean {
val accessToken = AccessToken.getCurrentAccessToken()
val isLoggedIn = accessToken != null && !accessToken.isExpired
return isLogin()
}
}
open fun setFaceBookLoginListener(faceBookLoginListener: FaceBookLoginListener?) {
this.mFaceBookLoginListener = faceBookLoginListener
}
interface FaceBookLoginListener {
fun onLoginSuccess(infoBean: FaceLoginInfoBean)
fun onLoginCancel(message: String?)
fun onLoginFail(message: String?)
fun onLogoutSuccess()
fun onLogoutFail()
}
}
8.Twitter登录工具类的封装：
kotlin
**
* @author: njb
* @date: 2021/5/14 10:08
* @desc: Twitter登录工具类
*/
class TwitterLoginUtils(activity: Activity) {
private var activityRef: WeakReference<Activity>? = null
var callback: Callback<TwitterSession>? = null
@Volatile
var authClient: TwitterAuthClient? = null
companion object {
const val ERROR_MSG_NO_ACTIVITY = ("TwitterLoginButton requires an activity."
+ " Override getActivity to provide the activity for this button.")
}
init {
activityRef = WeakReference(activity)
TwitterCore.getInstance()
}
fun setOnLoginByTwitterClick(callback: Callback<TwitterSession>?) {
this.callback = callback
checkCallback(callback)
checkActivity(activityRef?.get())
twitterAuthClient!!.authorize(activityRef?.get(), callback)
}
private val twitterAuthClient: TwitterAuthClient?
get() {
if (authClient == null) {
synchronized(TwitterLoginButton::class.java) {
if (authClient == null) {
authClient = TwitterAuthClient()
}
}
}
return authClient
}
private fun checkCallback(callback: Callback<*>?) {
if (callback == null) {
CommonUtils.logOrThrowIllegalStateException(TwitterCore.TAG,
"Callback must not be null, did you call setCallback?")
}
}
private fun checkActivity(activity: Activity?) {
if (activity == null || activity.isFinishing) {
CommonUtils.logOrThrowIllegalStateException(TwitterCore.TAG, ERROR_MSG_NO_ACTIVITY)
}
}
/**
* Call this method when [Activity]
* is called to complete the authorization flow.
*
* @param requestCode the request code used for SSO
* @param resultCode the result code returned by the SSO activity
* @param data the result data returned by the SSO activity
*/
fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode == twitterAuthClient!!.requestCode) {
twitterAuthClient!!.onActivityResult(requestCode, resultCode, data)
}
}
}
9.简单使用代码如下：
使用具体步骤如下：
9.1先判断用户是否安装Google服务
9.2先声明工具类
csharp
private var mGoogleLogin: GoogleLoginUtils? = null
private var mFacebookLoginUtils: FacebookLoginUtils? = null
9.3Google和FaceBook工具类的初始化
kotlin
private fun initGoogle() {
mGoogleLogin = GoogleLoginUtils(this, this)
mGoogleLogin?.setGoogleSignListener(this)
}
private fun initFaceBook() {
mFacebookLoginUtils = FacebookLoginUtils(this)
mFacebookLoginUtils?.setFaceBookLoginListener(this)
}9.4 Google、FaceBook调用不同的方法：
scss
R.id.iv_google -> {//先检查是否安装Google服务
checkGoogleService()
}
R.id.iv_face_book -> {//检查是否安装FaceBook客户端
if (!CheckApkExist.checkFacebookExist(this)) {
ToastUtils.showShort(getString(com.jiaoday.base.R.string.please_install_face_book_first))
} else {
mFacebookLoginUtils?.login()
}
}
kotlin
private fun checkGoogleService() {
val code = mGoogleLogin?.checkGooglePlayServiceExist(this)
if (code == ConnectionResult.SUCCESS) {
mGoogleLogin?.signIn()
} else {
code?.let { mGoogleLogin?.onCheckGooglePlayServices(this, it) }
}
}
9.5Google和FaceBook登录回调:
在最开始继承一下登录回调监听方法：
GoogleLoginUtils.GoogleSignListener, FacebookLoginUtils.FaceBookLoginListener
9.6登录成功、失败、取消登录后的回调
kotlin
override fun googleLoginSuccess(account: GoogleSignInAccount) {
//google登录成功后返回的信息
if (account.email != null) {
thirdAccountLogin(account.email.toString(), account.email.toString(), "4")
}
}
override fun googleLoginFail(message: String?) {
ToastUtils.showShort(message)
}
override fun googleLogoutSuccess() {
}
override fun googleLogoutFail() {
}
override fun onLoginSuccess(infoBean: FaceLoginInfoBean) {
//faceBook登录成功后返回的信息
if (infoBean.email.isNotEmpty()) {
thirdAccountLogin(infoBean.email, infoBean.email, "1") }
}
override fun onLoginCancel(message: String?) { ToastUtils.showShort(message) }
override fun onLoginFail(message: String?) { ToastUtils.showShort(message) }
override fun onLogoutSuccess() { }
override fun onLogoutFail() { }
9.7 onActivityResult回调结果：
kotlin
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == mGoogleLogin?.requestCode) {
val task: Task<GoogleSignInAccount> = GoogleSignIn.getSignedInAccountFromIntent(data)
mGoogleLogin?.handleSignInResult(task)
}
mFacebookLoginUtils?.getCallbackManager()?.onActivityResult(requestCode, resultCode, data)
}10. 懒加载：
kotlin中的懒加载很安逸，使用起来非常简单方便,举个栗子：
kotlin
private val mCallbackManager by lazy { CallbackManager.Factory.create() }
private val TAG by lazy { "MainActivity" }
private val mGoogleLoginUtils by lazy { GoogleLoginUtils(this, this) }11.完整的使用流程如下：
- 初始化view.
- 初始化Google和FaceBook.
- 添加事件监听.
- 检查googlePlay服务.
- FaceBook登录时检查是否安装FaceBook客户端.
- 添加登录回调(登录成功、失败、取消登录等).
12.初始化view:
kotlin
private fun initView() {
tv_google.setOnClickListener {
checkGoogleService()
}
tv_facebook.setOnClickListener {
if (!CheckApkExistUtils.checkFacebookExist(this)) {
Toast.makeText(this, "请先安装FaceBook客户端", Toast.LENGTH_LONG).show()
} else {
mFaceBookLoginUtils.login()
}
}
tv_twitter.setOnClickListener {
}
}
13.初始化Google和FaceBook：
kotlin
private fun initGoogle() {
mGoogleLoginUtils.setGoogleSignListener(this)
}
private fun initFaceBook() {
mFaceBookLoginUtils.setFaceBookLoginListener(this)
}14.添加事件监听：
kotlin
GoogleLoginUtils.GoogleLoginListener,
FaceBookLoginUtils.FaceBookLoginListener {
private val mFaceBookLoginUtils by lazy {
FaceBookLoginUtils(
this,
callbackManager = mCallbackManager
)
}
private val mCallbackManager by lazy { CallbackManager.Factory.create() }
private val TAG by lazy { "MainActivity" }
private val mGoogleLoginUtils by lazy { GoogleLoginUtils(this, this) }15.先检查是否安装Googleplay服务:
kotlin
/**
* 先检查用户是否安装Google服务
*/
private fun checkGoogleService() {
val code = CheckGoogleServiceUtils.checkGooglePlayServiceExist(this)
if (code == ConnectionResult.SUCCESS) {
mGoogleLoginUtils.signIn()
} else {
code.let { CheckGoogleServiceUtils.onCheckGooglePlayServices(this, it) }
}
}16.FaceBook登录时先检查是否安装客户端
kotlin
tv_facebook.setOnClickListener {
if (!CheckApkExistUtils.checkFacebookExist(this)) {
Toast.makeText(this, "请先安装FaceBook客户端", Toast.LENGTH_LONG).show()
} else {
mFaceBookLoginUtils.login()
}
}17.登录回调：
kotlin
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
Log.d(TAG, resultCode.toString())
if (mCallbackManager != null) {
mCallbackManager.onActivityResult(requestCode, resultCode, data)
}
if (requestCode == mGoogleLoginUtils.requestCode) {
val task: Task<GoogleSignInAccount> = GoogleSignIn.getSignedInAccountFromIntent(data)
mGoogleLoginUtils.handleSignInResult(task)
}
}18.完整Activity测试代码：
kotlin
package com.powervision.thirdlogindemo
import android.content.Intent
import android.os.Bundle
import android.util.Log
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity(), GoogleLoginUtils.GoogleLoginListener,
FaceBookLoginUtils.FaceBookLoginListener {
private val mFaceBookLoginUtils by lazy {
FaceBookLoginUtils(
this,
callbackManager = mCallbackManager
)
}
private val mCallbackManager by lazy { CallbackManager.Factory.create() }
private val TAG by lazy { "MainActivity" }
private val mGoogleLoginUtils by lazy { GoogleLoginUtils(this, this) }
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
initView()
initFaceBook()
initGoogle()
}
private fun initGoogle() {
mGoogleLoginUtils.setGoogleSignListener(this)
}
private fun initFaceBook() {
mFaceBookLoginUtils.setFaceBookLoginListener(this)
}
private fun initView() {
tv_google.setOnClickListener {
checkGoogleService()
}
tv_facebook.setOnClickListener {
if (!CheckApkExistUtils.checkFacebookExist(this)) {
Toast.makeText(this, "请先安装FaceBook客户端", Toast.LENGTH_LONG).show()
} else {
mFaceBookLoginUtils.login()
}
}
tv_twitter.setOnClickListener {
}
}
/**
* 先检查用户是否安装Google服务
*/
private fun checkGoogleService() {
val code = CheckGoogleServiceUtils.checkGooglePlayServiceExist(this)
if (code == ConnectionResult.SUCCESS) {
mGoogleLoginUtils.signIn()
} else {
code.let { CheckGoogleServiceUtils.onCheckGooglePlayServices(this, it) }
}
}
override fun onLoginSuccess(infoBean: FaceBookLoginInfoBean) {
//处理Facebook登录成功后的请求
}
override fun onLoginFailed(message: String) {
}
override fun onLoginCancel(message: String) {
}
override fun onLogoutSuccess() {
}
override fun onLogoutFailed() {
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
Log.d(TAG, resultCode.toString())
if (mCallbackManager != null) {
mCallbackManager.onActivityResult(requestCode, resultCode, data)
}
if (requestCode == mGoogleLoginUtils.requestCode) {
val task: Task<GoogleSignInAccount> = GoogleSignIn.getSignedInAccountFromIntent(data)
mGoogleLoginUtils.handleSignInResult(task)
}
}
override fun googleLoginSuccess(account: GoogleSignInAccount) {
//处理Google登录成功后的请求
}
override fun googleLoginFail(message: String?) {
}
override fun googleLogoutSuccess() {
}
override fun googleLogoutFail() {
}
}19.布局代码如下：

以上就是Google、Facebook、Twitter登录工具类的完整封装和使用流程，如有合适的你可以放到自己项目中，当然集成ShareSdk或者友盟可以很好的实现国外第三方登录，一键集成即可，不用专门去下载集成每一家的sdk,这里我做这个的封装是为了能够更好地使用，方便其他同事和项目，后面还可以做统一封装，只需要传递相应类型，登录成功和失败的方法回调出来就可以了.如有问题，及时沟通，我会努力改正，一起学习，共同进步，谢谢大家~~
