接着上一篇封装的Google、FaceBook登录工具类的封装后，我们这篇来说下实际项目中的具体使用：
1.当然本篇也使用了懒加载，最近刚学这个，觉得非常好用,举个栗子：
private val mCallbackManager by lazy { CallbackManager.Factory.create() }
private val TAG by lazy { "MainActivity" }
private val mGoogleLoginUtils by lazy { GoogleLoginUtils(this, this) }
2.初始化view:
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 {
}
}
3.初始化Google和FaceBook：
private fun initGoogle() {
mGoogleLoginUtils.setGoogleSignListener(this)
}
private fun initFaceBook() {
mFaceBookLoginUtils.setFaceBookLoginListener(this)
}
4.添加事件监听：
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) }
5.Google登录的时候需要先检查是否安装Googleplay服务:
/**
* 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) }
}
}
6.FaceBook登录的时候需要先检查是否安装Facebook客户端，当然浏览器也可以登录，但是没有App方便，经过和产品商量后直接使用App登录，方便快捷.
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()
}
}
7.登录回调：
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
mGoogleLoginUtils.handleSignInResult(task)
}
}
8.处理你自己的登录请求：
9.完整的Activity代码：
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
import com.facebook.CallbackManager
import com.google.android.gms.auth.api.signin.GoogleSignIn
import com.google.android.gms.auth.api.signin.GoogleSignInAccount
import com.google.android.gms.common.ConnectionResult
import com.google.android.gms.tasks.Task
import com.powervision.thirdlogindemo.bean.FaceBookLoginInfoBean
import com.powervision.thirdlogindemo.utils.CheckApkExistUtils
import com.powervision.thirdlogindemo.utils.CheckGoogleServiceUtils
import com.powervision.thirdlogindemo.utils.FaceBookLoginUtils
import com.powervision.thirdlogindemo.utils.GoogleLoginUtils
import kotlinx.android.synthetic.main.activity_main.*
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
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() {
}
}
10.布局文件代码：
xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> android:id="@+id/tv_google" android:layout_width="0dp" android:layout_height="40dp" android:text="Google登录" android:textColor="@color/white" android:background="@color/colorPrimary" android:gravity="center" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toLeftOf="@id/tv_facebook" app:layout_constraintTop_toTopOf="parent" /> android:id="@+id/tv_facebook" android:layout_width="0dp" android:layout_height="40dp" android:text="FaceBook登录" android:textColor="@color/white" android:background="@color/colorPrimary" android:gravity="center" android:layout_marginStart="20dp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toRightOf="@id/tv_google" app:layout_constraintRight_toLeftOf="@id/tv_twitter" app:layout_constraintTop_toTopOf="parent" /> android:id="@+id/tv_twitter" android:layout_width="0dp" android:layout_height="40dp" android:text="Twitter登录" android:textColor="@color/white" android:background="@color/colorPrimary" android:gravity="center" android:layout_marginStart="20dp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toRightOf="@id/tv_facebook" app:layout_constraintRight_toRightOf="parent" app:layout_constraintTop_toTopOf="parent" />
11.以上就是Google和Facebook登录的完整流程和代码，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,这里只是说下我做这个的封装和使用.如有问题，及时沟通，我们努力改正，谢谢~~
