本文介绍了一种简化登录流程的方法，通过省略短信验证码校验步骤，直接登录并获取服务器数据。适用于快速原型开发或内部测试环境。

LoginActivity.kt登录界面省去短信的校验，直接登录获取服务器数据

package com.example.takeout.ui.activity

class LoginActivity : AppCompatActivity() {

    //监听每一次提交验证码操作
    val eh = object : EventHandler() {
        override fun afterEvent(event: Int, result: Int, data: Any) {
            if (result == SMSSDK.RESULT_COMPLETE) {

                } else if (event == SMSSDK.EVENT_GET_VERIFICATION_CODE) {
                    //获取验证码成功
                    Log.d("LoginActivity", "获取验证码成功")
                } else if (event == SMSSDK.EVENT_GET_SUPPORTED_COUNTRIES) {
                    //返回支持发送验证码的国家列表
                }

    lateinit var loginActivityPresenter: LoginActivityPresenter

        loginActivityPresenter = LoginActivityPresenter(this)
        initListener()
        MobSDK.submitPolicyGrantResult(true, null);

        //注册短信回调
        SMSSDK.registerEventHandler(eh)

    }

    private fun initListener() {
        iv_user_back.setOnClickListener { finish() }
        //获取验证码
        tv_user_code.setOnClickListener {

            val phone = et_user_phone.text.toString().trim()
            //验证手机号码
            if (SMSUtil.judgePhoneNums(this, phone)) {
                // 请求验证码，其中country表示国家代码，如“86”；phone表示手机号码，如“13800138000”
                SMSSDK.getVerificationCode("86", phone)
                //开启倒计时
                tv_user_code.isEnabled = false
                Thread(CutDownTask()).start()

            }
        }
        iv_login.setOnClickListener {
            //提交验证码
            val phone = et_user_phone.text.toString().trim()
            val code = et_user_code.text.toString().trim()
            //下面是短信验证码的校验，先屏蔽
//            if (SMSUtil.judgePhoneNums(this, phone) && !TextUtils.isEmpty(code)) {
//                // 提交验证码，其中的code表示验证码，如“1357”
//                SMSSDK.submitVerificationCode("86", phone, code)
//            }
            //直接登录登录外卖服务器，省去短信验证码验证阶段
            loginActivityPresenter.loginByPhone(phone)
        }
    }

    companion object {
        val TIME_MINUS = -1 //剩余时间的消息
        val TIME_IS_OUT = 0 //60s超时
    }
    //创建一个handler来刷新UI
    val handler = @SuppressLint("HandlerLeak")
    object : Handler(){
        override fun handleMessage(msg: Message?) {
            super.handleMessage(msg)
            when(msg!!.what){
                TIME_MINUS -> tv_user_code.text = "剩余时间(${time})秒"
                TIME_IS_OUT -> {
                    tv_user_code.isEnabled = true
                    tv_user_code.text = "点击重发"
                    time = 60
                }
            }

        }
    }

    //倒计时的实现60s
    var time = 60
    inner class CutDownTask: Runnable {
        override fun run() {
            //倒计时循环
            while (time>0){
                //刷新剩余时间，当前子线程，使用handler
                handler.sendEmptyMessage(TIME_MINUS)
                SystemClock.sleep(999)
                time --
            }
            handler.sendEmptyMessage(TIME_IS_OUT)
        }
    }

    // 使用完EventHandler需注销，否则可能出现内存泄漏
    override fun onDestroy() {
        super.onDestroy()
        SMSSDK.unregisterEventHandler(eh)
    }

    fun onLoginSuccess() {
        finish()
        toast("登录成功")
    }

    fun onLoginFailed(){
        toast("登录失败")
    }
}

LoginActivityPresenter.kt登录的网络请求逻辑

package com.example.takeout.presenter

import com.example.takeout.beans.User
import com.example.takeout.ui.activity.LoginActivity
import com.example.takeout.utils.TakeoutApp
import com.google.gson.Gson

//继承NetPresenter
class LoginActivityPresenter(val loginActivity: LoginActivity) : NetPresenter(){

    //使用手机号码登录的业务
    fun loginByPhone(phone:String) {
        val homeCall = takeoutService.loginByPhone()
        homeCall.enqueue(callback)
    }

    override fun parserJson(json: String) {
        val user = Gson().fromJson(json, User::class.java)

        if (user != null) {
            //缓存到内存中
            TakeoutApp.sUser = user
            loginActivity.onLoginSuccess()
        } else{
            loginActivity.onLoginFailed()
        }
    }
}

UserFragment.kt登录成功以后用户展示界面的刷新

package com.example.takeout.ui.fragment

import android.app.Fragment
import android.content.Intent
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ImageView
import android.widget.LinearLayout
import com.example.takeout.R
import com.example.takeout.ui.activity.LoginActivity
import com.example.takeout.utils.TakeoutApp
import kotlinx.android.synthetic.main.fragment_user.*
import org.jetbrains.anko.find

class UserFragment : Fragment() {

    lateinit var ll_userinfo: LinearLayout
    lateinit var ivLogin:ImageView
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val userview = View.inflate(activity, R.layout.fragment_user, null)
        ll_userinfo = userview.find<LinearLayout>(R.id.ll_userinfo)
        ivLogin = userview.find<ImageView>(R.id.login)
        ivLogin.setOnClickListener {
            val intent = Intent(activity, LoginActivity::class.java)
            activity.startActivity(intent)
        }
        return userview
    }

    override fun onStart() {
        super.onStart()
        //展示登录成功后的ui效果
        val user = TakeoutApp.sUser
        if (user.id == -1) {
            //未登录
            ll_userinfo.visibility = View.GONE
            ivLogin.visibility = View.VISIBLE
        } else {
            ivLogin.visibility = View.GONE
            ll_userinfo.visibility = View.VISIBLE
            username.text = "欢迎您，${user.name}"
            phone.text = user.phone
        }
    }
}

TakeoutApp.kt保存登录的数据

package com.example.takeout.utils

import android.app.Application
import com.example.takeout.beans.User

class TakeoutApp : Application() {

    companion object {
        var sUser: User = User()
        lateinit var sInstance: TakeoutApp
    }

    //应用程序的入口
    override fun onCreate() {
        super.onCreate()
        sInstance = this
        sUser.id = -1 //未登录用户id=-1
    }

}

User.kt用户的bean数据，对bean的数据进行初始化

package com.example.takeout.beans

import java.io.Serializable


data class User(
    var id: Int = 0,
    var name: String? = null,
    var balance: Float = 0.toFloat(),
    var discount: Int = 0,
    var integral: Int = 0,
    var phone: String? = null
) : Serializable {

//    var id: Long = 0
//    var pic: String? = null
//    var name: String? = null
//
//    var score: String? = null
//    var sale: String? = null
//    var ensure: String? = null
//
//    var invoice: String? = null
//    var sendPrice: String? = null
//    var deliveryFee: String? = null
//
//    var recentVisit: String? = null
//    var distance: String? = null
//    var time: String? = null
//
//    var icon: String? = null
//
//    var activityList: ArrayList<ActivityInfo>? = null

}

登录成功以后的展示界面如下：
