Android自定义来电秀实现总结-编程学习网

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

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" />
    <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">
                <action android:name="android.intent.action.DUAL_PHONE_STATE" />
            </intent-filter>
            <intent-filter android:priority="2147483647">
                <action android:name="android.intent.action.PHONE_STATE_2" />
            </intent-filter>
            <intent-filter android:priority="2147483647">
                <action android:name="com.cootek.smartdialer.action.PHONE_STATE" />
            </intent-filter>
            <intent-filter android:priority="2147483647">
                <action android:name="com.cootek.smartdialer.action.INCOMING_CALL" />
            </intent-filter>
        </receiver>

# PhoneStateReceiver.kt
class PhoneStateReceiver : BroadcastReceiver() {
    override fun onReceive(context: Context?, intent: Intent?) {
        context?.let {
            val action = intent?.action
            if (Intent.ACTION_NEW_OUTGOING_CALL == action || TelephonyManager.ACTION_PHONE_STATE_CHANGED == action) {
                try {
                    val manager = it.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
                    var state = manager.callState
                    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(state: 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_IMMERSIVE_STICKY 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：

# PhoneCallUtil.kt

    fun answer() {
        when {
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.P -> {
                val telecomManager = App.context.getSystemService(Context.TELECOM_SERVICE) as TelecomManager
                if (ActivityCompat.checkSelfPermission(App.context, Manifest.permission.ANSWER_PHONE_CALLS) != PackageManager.PERMISSION_GRANTED) {
                    return
                }
                telecomManager.acceptRingingCall()
            }
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP -> {
                finalAnswer()
            }
            else -> {
                try {
                    val method: Method = Class.forName("android.os.ServiceManager")
                            .getMethod("getService", String::class.java)
                    val binder = method.invoke(null, Context.TELEPHONY_SERVICE) as IBinder
                    val telephony = ITelephony.Stub.asInterface(binder)
                    telephony.answerRingingCall()
                } catch (e: Exception) {
                    finalAnswer()
                }
            }
        }
    }
    private fun finalAnswer() {
        try {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                val mediaSessionManager = App.context.getSystemService("media_session") as MediaSessionManager
                val activeSessions = mediaSessionManager.getActiveSessions(ComponentName(App.context, NotificationService::class.java)) as List<MediaController>
                if (activeSessions.isNotEmpty()) {
                    for (mediaController in activeSessions) {
                        if ("com.android.server.telecom" == mediaController.packageName) {
                            mediaController.dispatchMediaButtonEvent(KeyEvent(0, 79))
                            mediaController.dispatchMediaButtonEvent(KeyEvent(1, 79))
                            break
                        }
                    }
                }
            }
        } catch (e: Exception) {
            e.printStackTrace()
            answerPhoneAidl()
        }
    }
    private fun answerPhoneAidl() {
        try {
            val keyEvent = KeyEvent(0, 79)
            val keyEvent2 = KeyEvent(1, 79)
            if (Build.VERSION.SDK_INT >= 19) {
                @SuppressLint("WrongConstant") val audioManager = App.context.getSystemService("audio") as AudioManager
                audioManager.dispatchMediaKeyEvent(keyEvent)
                audioManager.dispatchMediaKeyEvent(keyEvent2)
            }
        } catch (ex: java.lang.Exception) {
            val intent = Intent("android.intent.action.MEDIA_BUTTON")
            intent.putExtra("android.intent.extra.KEY_EVENT", KeyEvent(0, 79) as Parcelable)
            App.context.sendOrderedBroadcast(intent, "android.permission.CALL_PRIVILEGED")
            val intent2 = Intent("android.intent.action.MEDIA_BUTTON")

            App.context.sendOrderedBroadcast(intent2, "android.permission.CALL_PRIVILEGED")
        }
    }
    
    fun disconnect() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            with(PhoneCallManager.instance) {
                if (!hasDefaultCall()) {
                    return@with
                }
                mainCallId?.let {
                    val result = disconnect(it)
                    if (result) {
                        return
                    }
                }
            }
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            val telecomManager = App.context.getSystemService(Context.TELECOM_SERVICE) as TelecomManager
            if (ActivityCompat.checkSelfPermission(App.context, Manifest.permission.ANSWER_PHONE_CALLS) != PackageManager.PERMISSION_GRANTED) {
                return
            }
            telecomManager.endCall()
        } else {
            try {
                val method: Method = Class.forName("android.os.ServiceManager")

                telephony.endCall()
            } catch (e: Exception) {
                e.printStackTrace()
            }
        }
    }

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 -->
        <service
            android:name=".phone.service.PhoneCallService"
            android:permission="android.permission.BIND_INCALL_SERVICE">
            <!-- name为自己的Service名字，per和 filter中的name为固定值 -->
            <intent-filter>
                <action android:name="android.telecom.InCallService" />
            </intent-filter>
            <meta-data
                android:name="android.telecom.IN_CALL_SERVICE_UI"
                android:value="true" />
        </service>

# PhoneCallService.kt 
@RequiresApi(Build.VERSION_CODES.M)
class PhoneCallService : InCallService() {
    companion object {
        const val ACTION_SPEAKER_ON = "action_speaker_on"
        const val ACTION_SPEAKER_OFF = "action_speaker_off"
        const val ACTION_MUTE_ON = "action_mute_on"
        const val ACTION_MUTE_OFF = "action_mute_off"
        fun startService(action: String?) {
            val intent = Intent(App.context, PhoneCallService::class.java).apply {
                this.action = action
            }
            App.context.startService(intent)
        }
    }
    // Call 添加 （Call对象需要判断是否有多个呼入的情况）
    override fun onCallAdded(call: Call?) {
        super.onCallAdded(call)
        call?.let {
            it.registerCallback(callback)
            PhoneCallManager.instance.addCall(it)
        }
    }
    // Call 移除 （可以理解为某一个通话的结束）
    override fun onCallRemoved(call: Call?) {
        super.onCallRemoved(call)
        call?.let {
            it.unregisterCallback(callback)
            PhoneCallManager.instance.removeCall(it)
        }
    }
    override fun onCanAddCallChanged(canAddCall: Boolean) {
        super.onCanAddCallChanged(canAddCall)
        PhoneCallManager.instance.onCanAddCallChanged(canAddCall)
    }
    // 将Call CallBack放在PhoneCallManager类中统一处理
    private val callback: Call.Callback = object : Call.Callback() {
        override fun onStateChanged(call: Call?, state: Int) {
            super.onStateChanged(call, state)
            PhoneCallManager.instance.onCallStateChanged(call, state)
        }
        override fun onCallDestroyed(call: Call) {
            call.hold()
            super.onCallDestroyed(call)
        }
    }
    // 设置扬声器
    override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
        when (intent?.action) {
            ACTION_SPEAKER_ON -> setAudioRoute(CallAudioState.ROUTE_SPEAKER)
            ACTION_SPEAKER_OFF -> setAudioRoute(CallAudioState.ROUTE_EARPIECE)
            ACTION_MUTE_ON -> setMuted(true)
            ACTION_MUTE_OFF -> setMuted(false)
            else -> {
            }
        }
        return super.onStartCommand(intent, flags, startId)
    }
}

以上为InCallService的代码。部分方法进行了说明。

# PhoneCallManager.kt

    @RequiresApi(Build.VERSION_CODES.M)
    fun answer(callId: String?) =
            getCallById(callId)?.let {
                it.answer(VideoProfile.STATE_AUDIO_ONLY)
                true
            } ?: false
    
    @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。
