        前言

        该文章为对工作中部分业务实现的总结,阅读时间:20分钟,版本:android 6.0 - 9.0 update time 2021年02月03日11:48:55 文章可能存在不足之处,还望评论批评,一起学习进步。

        要想实现自定义 来电秀,首先我们先这样 再这样,然后你这样,最后你再这样一下,就可以了,很好实现的,听懂了么?-,-

        效果图

        Android 自定义来电秀实现总结

        TODO

        • 添加包活lib,提高App在设置成功后 退居后台,成功拉起的概率
        • 项目中已经包含lib_ijk的代码,我们可以添加视频来电展示,添加美女或者豪车等全屏视频,效果更佳。
        • 由于反编译能力有限,对于多种机型权限的跳转(后续可以开起 无障碍服务,直接一步搞定多种需要用户手动设置操作)
        • 该Demo中有一部分不完善的Rom 权限跳转机制,后续还需要时间来完善。

        来电秀实现

        实现思想

        • 通过监听手机Service 分辨来电状态,然后弹出我们自定义的来电页面,覆盖系统来电页面。
        • 通过相关API (主要两种:读取来电系统的Notification信息 和 模拟耳机线控的方式进行挂断/接听)实现接听和挂断功能。我这里会使用两种(低版本 使用电话状态广播监听,高版本使用InCallService) 监听电话状态的Service 及两种界面展示 来呈现来电信息,多个界面和多个Service的监听 能够增加高版本的容错率兼容性。
        • 实现自定义的拨号界面 或者 直接使用系统的拨号界面。

        注意:因为篇幅问题,博客只会截取部分代码,太长读者很难读下去,Demo已经调试通过,如果有想看源码的可以移步到我的 github项目地址

        申请权限

        静态权限

          电话应用,会用到很多权限,我这里尽可能多的静态注册了一些权限,如果引入项目中,需要甄别下,代码如下:

            <uses-permission android:name="android.permission.INTERNET" />
            <uses-permission android:name="android.permission.Access_NETWORK_STATE" />
            <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
            <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
            <uses-permission android:name="android.permission.READ_PHONE_STATE" />
            <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"开发者_JAV培训 />
            <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
            <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
            <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
            <uses-permission android:name="android.permission.WRITE_SETTINGS" />
            <!-- 读取联系人权限 -->
            <uses-permission android:name="android.permission.READ_CONTACTS" />
            <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
            <uses-permission android:name="android.permission.WAKE_LOCK" />
            <uses-permission android:name="android.permission.DEVICE_POWER" />
            <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
            <uses-permission android:name="android.permission.CALL_PHONE" />
            <uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
            <uses-permission android:name="android.permission.PACKAGE_USAGE_STATS" />
            <uses-permission android:name="android.permission.ANSWER_PHONE_CALLS" />
            <!-- 读写 联系信息 显示联系人名称 -->
            <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /> 
            <uses-permission android:name="android.permission.READ_CALL_LOG" />
            <uses-permission android:name="android.permission.WRITE_CALL_LOG" />
            <uses-permission android:name="android.permission.READ_LOGS" />
            <uses-permission android:name="android.permission.RECORD_AUDIO" />
            <uses-permission android:name="android.permission.VIBRATE" />
            <uses-permission android:name="android.permission.GET_TASKS" />
            <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
            <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
            <uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />
            <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
            <uses-permission android:name="android.permission.BROADCAST_PACKAGE_ADDED" />
            <uses-permission android:name="android.permission.BROADCAST_PACKAGE_CHANGED" />
            <uses-permission android:name="android.permission.BROADCAST_PACKAGE_INSTALL" />
            <uses-permission android:name="android.permission.BROADCAST_PACKAGE_REPLACED" />
            <uses-permission android:name="android.permission.RESTART_PACKAGES" />
            <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
            <!--android 9.0上使用前台服务,需要添加权限-->
            <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
            <permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" />
        

        动态权限

          AndPermission.with(this)
                        .runtime()
                        .permission(
                                Permission.Group.PHONE,
                                Permission.Group.LOCATION,
                                Permission.Group.CALL_LOG
                        )
                        .onGranted {
                            Toast.makeText(applicationContext, "权限同意", Toast.LENGTH_SHORT).show()
                        }.onDenied {
                            Toast.makeText(applicationContext, "权限拒绝", Toast.LENGTH_SHORT).show()
                        }.start()
        

          上述代码,为自己测试使用的Demo,所以请求权限直接请求分组中的全部权限了,项目中根据需要动态申请部分权限

          虽然我们已经申请了这么多权限,但是为了能够替换系统电话界面成功,还有一部分权限是需要通过弹框来引导用户去 设置中开启的。

        // 暂时把重要代码cv出来了一部分,建议下载Demo源码 ,结合博客一起观看
        

          上述代码 主要罗列了需要引导用户开启部分设置权限的核心代码和方法。

        监听电话

          对于监听电话这块,会有很多兼容性的问题,我们这里先使用广播监听 action = android.intent.action.PHONE_STATE 的广播,然后根据状态调用起来悬浮窗。但是测试Android高版本手机 发现 InCallService 会更好的获取到电话状态,所以我这里的处理方案是 两个方案都保存在了代码中,最后通过调用不同的界面来区分。

        BroadcastReceiver +悬浮窗显示实现

        # AndroidManifest.XML
        // 监听电话状态广播 注册
        <receiver android:name=".phone.receiver.PhoneStateReceiver">
                    <intent-filter android:priority="2147483647">
                        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
                        <category android:name="android.intent.category.DEFAULT" />
                    </intent-filter>
                    <intent-filter android:priority="2147483647">
                        <action android:name="android.intent.action.PHONE_STATE" />
                    </intent-filter>
                    <intent-filter android:priority="2147483647">

                            val phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER)
                            if (Intent.ACTION_NEW_OUTGOING_CALL.equals(action, true)) {
                                state = 1000
                            }
                            dealWithCallAction(state, phoneNumber)
                        } catch (e: Exception) {
                        }
                    }
                }
            }
            //来去电的几个状态
            private fun dealWithCallAction(stahttp://www.devze.comte: Int?, phoneNumber: String?) {
                when (state) {
                    // 来电状态 - 显示悬浮窗
                    TelephonyManager.CALL_STATE_RINGING -> {
                        PhoneStateActionImpl.instance.onRinging(phoneNumber)
                    }
                    // 空闲状态(挂断) - 关闭悬浮窗
                    TelephonyManager.CALL_STATE_IDLE -> {
                        PhoneStateActionImpl.instance.onHandUp()
                    }
                    // 摘机状态(接听) - 保持不作操作
                    TelephonyManager.CALL_STATE_OFFHOOK -> {
                        PhoneStateActionImpl.instance.onPickUp(phoneNumber)
                    }
                    1000 -> {   //拨打电话广播状态  - 显示悬浮窗
                        PhoneStateActionImpl.instance.onCallOut(phoneNumber)
                    }
                }
            }
        }
        

        获取到广播的信息后 我们就可以着手 悬浮窗的绘制和 初始化工作

        # FloatingWindow.kt
        private fun initView() {
                windowManager = mContext?.getSystemService(Context.WINDOW_SERVICE) as WindowManager
                params = WindowManager.LayoutParams()
                //高版本适配 全面/刘海屏
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
                    params.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
                }
                params.gravity = Gravity.CENTER
                params.width = WindowManager.LayoutParams.MATCH_PARENT
                params.height = WindowManager.LayoutParams.MATCH_PARENT
                params.screenOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
                params.format = PixelFormat.TRANSLUCENT
                // 设置 Window flag 为系统级弹框 | 覆盖表层
                params.type = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
                    WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY
                else
                    WindowManager.LayoutParams.TYPE_PHONE
                // 去掉FLAG_NOT_FOCUSABLE隐藏输入 全面屏隐藏虚拟物理按钮办法
                params.flags = WindowManager.LayoutParams.FLAG_FULLSCREEN or
                        WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS or
                        WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION or
                        WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
                params.systemUiVisibility =
                        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or

                                View.SYSTEM_UI_FLAG_FULLSCREEN
                val interceptorLayout: FrameLayout = object : FrameLayout(mContext!!) {
                    override fun dispatchKeyEvent(event: KeyEvent): Boolean {
                        if (event.action == KeyEvent.ACTION_DOWN) {
                            if (event.keyCode == KeyEvent.KEYCODE_BACK) {
                                return true
                            }
                        }
                        return super.dispatchKeyEvent(event)
                    }
                }
                phoneCallView = LayoutInflater.from(mContext).inflate(R.layout.view_phone_call, interceptorLayout)
                tvCallNumber = phoneCallView.findViewById(R.id.tv_call_number)
                tvPhoneHangUp = phoneCallView.findViewById(R.id.tv_phone_hang_up)
                tvPhonePickUp = phoneCallView.findViewById(R.id.tv_phone_pick_up)
                tvCallingTime = phoneCallView.findViewById(R.id.tv_phone_calling_time)
                tvCallRemark = phoneCallView.findViewById(R.id.tv_call_remark)
            }
        ... 
        // 部分代码省略
        

          悬浮窗展示完成后,就要设置电话接通和挂断的操作(注意:这里很多低版本手机存在兼容问题,所以会有一些代码比较奇怪)

        # IPhoneCallListenerImpl.kt
        override fun onAnswer() {
                val mContext = App.context
                try {
                    val intent = Intent(mContext, ForegroundActivity::class.java)
                    intent.action = CallListenerService.ACTION_PHONE_CALL
                    intent.putExtra(CallListenerService.PHONE_CALL_ANSWER, "0")
                    intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
                    mContext.startActivity(intent)
                } catch (e: Exception) {
                    Log.e("ymc","startForegroundActivity exception>>$e")
                    PhoneCallUtil.answer()
                }
            }
            override fun onOpenSpeaker() {
                PhoneCallUtil.openSpeaker()
            }
            override fun onDisconnect() {
                Log.e("ymc"," onDisconnect")
                val mContext = App.context
                try {
                    val intent = Intent(mContext, ForegroundActivity::class.java)
                    intent.action = CallListenerService.ACTION_PHONE_CALL
                    intent.putExtra(CallListenerService.PHONE_CALL_DISCONNECT, "0")
                    intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
                    mContext.startActivity(intent)
                } catch (e: Exception) {
                    Log.e("ymc","startForegroundActivity exception>>$e")
                    PhoneCallUtil.disconnect()
                }
            }
        

          以上代码为接口实现类,我们这里会跳转到 一个前台Activity(一定程度上可以将App拉活),主要逻辑我们放在自己的前台Service中操作。

        # CallListenerService.kt
        // Andorid新版本 启动服务的方式
        fun forceForeground(intent: Intent) {
                try {
                    ContextCompat.startForegroundService(App.context, intent)
                    notification = CustomNotifyManager.instance?.getNotifyNotification(App.context)
                    if (notification != null) {
                        startForeground(CustomNotifyManager.STEP_COUNT_NOTIFY_ID, notification)
                    } else {
                        startForeground(CustomNotifyManager.STEP_COUNT_NOTIFY_ID,
                                CustomNotifyManager.instance?.getDefaultNotification(NotificationCompat.Builder(App.context)))
                    }
                } catch (e: Exception) {
                }
            }
            override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
                if (intent == null) {
                    return START_STICKY
                }
                val action = intent.action ?: return START_STICKY
                when (action) {
                    ACTION_PHONE_CALL -> {
                        dispatchAction(intent)
                    }
                }
                return START_STICKY
            }
        private fun dispatchAction(intent: Intent) {
                if (intent.hasExtra(PHONE_CALL_DISCONNECT)) {
                    PhoneCallUtil.disconnect()
                    return
                }
                if (intent.hasExtra(PHONE_CALL_ANSWER)) {
                    PhoneCallUtil.answer()
                }
            }
        

          为保证我们的服务能够正常吊起来,吊起前台服务,并设置Service等级,代码如下:

        # AndroidManifest.xml
        <!-- 电话状态接收广播 -->
                <service
                    android:name=".phone.service.CallListenerService"
                    android:enabled="true"
                    android:exported="false">
                    <intent-filter android:priority="1000">
                        <action android:name="com.maiya.call.phone.service.CallListenerService" />
                    </intent-filter>
                </service>
        <!-- 监听通知栏权限 必备 -->
        <service
                    android:name=".phone.service.NotificationService"
                    android:label="@string/app_name"
                    android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
                    <intent-filter>
                        <action android:name="android.service.notification.NotificationListenerService" />
                    </intent-filter>
                </service>
        

           低版本的接通和挂断电话,因为需要兼容部分机型,所以我们会有比较多的判断,代码如下:

          到这里中低版本的电话接通和挂断,基本已经完毕。下一步 我们主要写,用户在同意设置应用为默认电话应用后的 更加简单方便的实现方式。

        InCallService + Activity实现

        在使用 InCallService 服务的同时,需要设置该应用为默认拨号应用 (这里只说明技术的可能性,不对用户行为分析)。

        # AndroidManifest.xml
        <!-- 电话service -->

          以上为InCallService的代码。部分方法进行了说明。

        # PhoneCallManager.kt
        /**
             * 接听电话
             */
            @RequiresApi(Build.VERSION_CODES.M)
            fun answer(callId: String?) =
                    getCallById(callId)?.let {
                        it.answer(VideoProfile.STATE_AUDIO_ONLY)
                        true
                    } ?: false
            /**
             * 断开电话,包括来电时的拒接以及接听后的挂断
             */
            @RequiresApi(Build.VERSION_CODES.M)
            fun disconnect(callId: String?) =
                    getCallById(callId)?.let {
                        it.disconnect()
                        true
                    } ?: false
        

        由于篇幅问题,PhoneCallManager中的代码不全部展示,需要的小伙伴请移步Github,该类中主要进行了一些默认拨号应用,呼叫Call是否保持等一些操作。
