最近由于项目做国际化，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，本博客采用的是Kotlin代码，不熟悉Kotlin的同学可以学习一下，直接上封装的代码：
一、接入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:
/*** 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)}
二.Google登录工具类的封装：
/*** @author: njb* @date: /5/8 14:37* @desc: Google登录工具类*/open class GoogleLoginUtils(private val activity: Activity, var listener: GoogleSignListener) {var requestCode = 10private var mGoogleSignInClient: GoogleSignInClient? = nullprivate var googleSignListener: GoogleSignListener? = nullinit {//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!!.signInIntentactivity.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> = completedTaskif (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)}}
三、FaceBook登录工具类的封装：
/***@author: njb*@date: /5/8 14:26*@desc: FaceBook登录工具类*/open class FacebookLoginUtils(private val activity: Activity) {private var loginManager: LoginManager? = nullprivate val permissions: List<String>private var callbackManager: CallbackManager? = nullprivate var requestSuccessCode = 2896private var requestCancelCode = 2897private var requestFailedCode = 2898private var mFaceBookLoginListener: FaceBookLoginListener? = nullvar infoBean: FaceLoginInfoBean? = nullinit {//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(_facebook_loginview_log_out_action)var cancel = activity.resources.getString(_facebook_loginview_cancel_action)val message: Stringval profile: Profile = Profile.getCurrentProfile()message = if (profile?.name != null) {java.lang.String.format(activity.resources.getString(_facebook_loginview_logged_in_as),profile.name)} else {activity.resources.getString(_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:13813813888val name = optString("name") //比如：Zhang Sanval gender = optString("gender") //性别：比如 male （男） female （女）val email = optString("email") //邮箱：比如：11111@//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 = idinfoBean?.name = nameinfoBean?.email = emailinfoBean?.gender = genderinfoBean?.picture = object_pic.toString()infoBean?.data = object_data.toString()infoBean?.photo = photoinfoBean?.locale = localeinfoBean?.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 = parametersrequest.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.isExpiredreturn 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()}}
四、Twitter登录工具类的封装：
*** @author: njb* @date: /5/14 10:08* @desc: Twitter登录工具类*/class TwitterLoginUtils(activity: Activity) {private var activityRef: WeakReference<Activity>? = nullvar callback: Callback<TwitterSession>? = null@Volatilevar authClient: TwitterAuthClient? = nullcompanion 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 = callbackcheckCallback(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)}}}
五、具体使用代码如下：
5.1------使用Google登录时需要先判断用户是否安装Google服务，
5.2------使用具体步骤如下：
a. 先声明工具类
private var mGoogleLogin: GoogleLoginUtils? = nullprivate var mFacebookLoginUtils: FacebookLoginUtils? = null
b.Google和FaceBook工具类的初始化
private fun initGoogle() {mGoogleLogin = GoogleLoginUtils(this, this)mGoogleLogin?.setGoogleSignListener(this)}private fun initFaceBook() {mFacebookLoginUtils = FacebookLoginUtils(this)mFacebookLoginUtils?.setFaceBookLoginListener(this)}
c.点击Google和FaceBook两个按钮分别调用不同的方法
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()}}
private fun checkGoogleService() {val code = mGoogleLogin?.checkGooglePlayServiceExist(this)if (code == ConnectionResult.SUCCESS) {mGoogleLogin?.signIn()} else {code?.let { mGoogleLogin?.onCheckGooglePlayServices(this, it) }}}
d.Google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
e.登录成功、失败、取消登录后的回调
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() { }
f.onActivityResult回调结果：
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)}
六、登录成功后处理自己的登录逻辑，调用第三方登录接口，这里Google登录使用的是最新的api,如果找不到导包大家可以修改版本，后面会给出源码地址，这里只是简单说出使用步骤,这里基本上三种登录都已经在项目中成功使用，大家可以尝试一下，如有问题，及时提出，我会修改.
