关于android:自定义来电秀怎么实现Android-来电秀源码分析

jiezi

前言

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？

效果图

TODO

  1. 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
  2. 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。
  3. 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）
  4. 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。

实现思维

  1. 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。
  2. 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。
  3. 实现自定义的拨号界面 或者 间接应用零碎的拨号界面。

申请权限

动态权限

  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.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 分割信息 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" />

动静权限

  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。

监听电话

  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。

BroadcastReceiver + 悬浮窗显示实现

# 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：

            android:name=".phone.service.CallListenerService"

            </intent-filter>
        </service>
<!-- 监听告诉栏权限 必备 -->

   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

/**

     */
    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()
                }
            }
        }
    }

                }
            }
        } 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")

            App.context.sendOrderedBroadcast(intent2, "android.permission.CALL_PRIVILEGED")
        }
    }

    /**
     * 断开电话，包含复电时的拒接以及接听后的挂断
     */
    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}
                }

            }
        }

    }

  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。

InCallService + Activity 实现

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。

最初

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。
