要想实现自定义复电秀，首先咱们先这样再这样，而后你这样，最初你再这样一下，就能够了，很好实现的，听懂了么？

增加包活 lib，进步 App 在设置胜利后退居后盾，胜利拉起的概率
我的项目中曾经蕴含 lib_ijk 的代码，咱们能够增加视频复电展现，增加美女或者豪车等全屏视频，成果更佳。
因为反编译能力无限，对于多种机型权限的跳转（后续能够开起 无障碍服务，间接一步搞定多种须要用户手动设置操作）
该 Demo 中有一部分不欠缺的 Rom 权限跳转机制，后续还须要工夫来欠缺。

通过监听手机 Service 分辨复电状态，而后弹出咱们自定义的复电页面，笼罩零碎复电页面。
通过相干 API（次要两种：读取复电零碎的 Notification 信息 和 模仿耳机线控的形式进行挂断 / 接听）实现接听和挂断性能。我这里会应用两种（低版本应用电话状态播送监听，高版本应用 InCallService）监听电话状态的 Service 及两种界面展现来出现复电信息，多个界面和多个 Service 的监听可能减少高版本的容错率兼容性。
实现自定义的拨号界面或者间接应用零碎的拨号界面。

电话利用，会用到很多权限，我这里尽可能多的动态注册了一些权限，如果引入我的项目中，须要甄别下，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.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 分割信息 显示联系人名称 -->

    <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 上应用前台服务，须要增加权限 -->
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" />

  AndPermission.with(this)
                .runtime()
                .permission(
                        Permission.Group.PHONE,
                        Permission.Group.LOCATION,
                        Permission.Group.CALL_LOG
                )
                .onGranted {Toast.makeText(applicationContext, "权限批准", Toast.LENGTH_SHORT).show()}.onDenied {Toast.makeText(applicationContext, "权限回绝", Toast.LENGTH_SHORT).show()}.start()
复制代码

上述代码，为本人测试应用的 Demo，所以申请权限间接申请分组中的全副权限了，我的项目中依据须要动静申请局部权限

尽管咱们曾经申请了这么多权限，然而为了可能替换零碎电话界面胜利，还有一部分权限是须要通过弹框来疏导用户去设置中开启的。

上述代码次要列举了须要疏导用户开启局部设置权限的外围代码和办法。

对于监听电话这块，会有很多兼容性的问题，咱们这里先应用播送监听 action = android.intent.action.PHONE_STATE 的播送，而后依据状态调用起来悬浮窗。然而测试 Android 高版本手机发现 InCallService 会更好的获取到电话状态，所以我这里的解决计划是两个计划都保留在了代码中，最初通过调用不同的界面来辨别。

# AndroidManifest.xml

// 监听电话状态播送 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>
复制代码
# 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) {
            // 复电状态 - 显示悬浮窗
            TelephonyManager.CALL_STATE_RINGING -> {PhoneStateActionImpl.instance.onRinging(phoneNumber)
            }
            // 闲暇状态(挂断) - 敞开悬浮窗
            TelephonyManager.CALL_STATE_IDLE -> {PhoneStateActionImpl.instance.onHandUp()
            }
            // 摘机状态(接听) - 放弃不作操作
            TelephonyManager.CALL_STATE_OFFHOOK -> {PhoneStateActionImpl.instance.onPickUp(phoneNumber)
            }
            1000 -> {   // 拨打电话播送状态  - 显示悬浮窗
                PhoneStateActionImpl.instance.onCallOut(phoneNumber)
            }
        }
    }


}
复制代码

获取到播送的信息后咱们就能够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 为零碎级弹框 | 笼罩表层
        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 暗藏输出 全面屏暗藏虚构物理按钮方法
        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)
    }

... 
// 局部代码省略
复制代码

悬浮窗展现实现后，就要设置电话接通和挂断的操作（留神：这里很多低版本手机存在兼容问题，所以会有一些代码比拟奇怪）

# 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()}

    }
复制代码

以上代码为接口实现类，咱们这里会跳转到一个前台 Activity（肯定水平上能够将 App 拉活），次要逻辑咱们放在本人的前台 Service 中操作。

# CallListenerService.kt

// Andorid 新版本 启动服务的形式
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()
        }
    }
复制代码

为保障咱们的服务可能失常吊起来，吊起前台服务，并设置 Service 等级，代码如下：

# AndroidManifest.xml

<!-- 电话状态接管播送 -->
        <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>
<!-- 监听告诉栏权限 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>
复制代码

低版本的接通和挂断电话，因为须要兼容局部机型，所以咱们会有比拟多的判断，代码如下：

# PhoneCallUtil.kt

到这里中低版本的电话接通和挂断，根本曾经结束。下一步咱们次要写，用户在批准设置利用为默认电话利用后的更加简略不便的实现形式。

在应用 InCallService 服务的同时，须要设置该利用为默认拨号利用（这里只阐明技术的可能性，不对用户行为剖析）。

# AndroidManifest.xml

<!-- 电话 service -->
        <service
            android:name=".phone.service.PhoneCallService"
            android:permission="android.permission.BIND_INCALL_SERVICE">
            <!-- name 为本人的 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>
复制代码
# 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 增加（Call 对象须要判断是否有多个呼入的状况）override fun onCallAdded(call: Call?) {super.onCallAdded(call)
        call?.let {it.registerCallback(callback)
            PhoneCallManager.instance.addCall(it)
        }
    }

    // Call 移除（能够了解为某一个通话的完结）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 类中对立解决
    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)
    }
}
复制代码

以上为 InCallService 的代码。局部办法进行了阐明。

# 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，包含复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
复制代码

因为篇幅问题，PhoneCallManager 中的代码不全副展现，须要的小伙伴请移步 Github，该类中次要进行了一些默认拨号利用，呼叫 Call 是否放弃等一些操作。

到这里这篇文章根本曾经写得差不多了，在本人编写 Demo 的时候也观看了很多其余的自定义复电秀博客，并且反编译了一些市面上不错的复电秀 App，如果有哪里侵权的中央，私信沟通，我会进行批改。感激大家可能观看我的开发笔记总结。
