Android?自定義來(lái)電秀實(shí)現(xiàn)總結(jié)

更新時(shí)間：2023年01月18日 14:07:08 作者：小肥羊沖沖沖Android

這篇文章主要為大家介紹了Android?自定義來(lái)電秀實(shí)現(xiàn)總結(jié)示例詳解，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進(jìn)步，早日升職加薪

前言

該文章為對(duì)工作中部分業(yè)務(wù)實(shí)現(xiàn)的總結(jié)，閱讀時(shí)間：20分鐘，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處，還望評(píng)論批評(píng)，一起學(xué)習(xí)進(jìn)步。

要想實(shí)現(xiàn)自定義來(lái)電秀，首先我們先這樣再這樣，然后你這樣，最后你再這樣一下，就可以了，很好實(shí)現(xiàn)的，聽懂了么？-，-

效果圖

添加包活lib，提高App在設(shè)置成功后退居后臺(tái)，成功拉起的概率
項(xiàng)目中已經(jīng)包含lib_ijk的代碼，我們可以添加視頻來(lái)電展示，添加美女或者豪車等全屏視頻，效果更佳。
由于反編譯能力有限，對(duì)于多種機(jī)型權(quán)限的跳轉(zhuǎn)（后續(xù)可以開起無(wú)障礙服務(wù)，直接一步搞定多種需要用戶手動(dòng)設(shè)置操作）
該Demo中有一部分不完善的Rom 權(quán)限跳轉(zhuǎn)機(jī)制，后續(xù)還需要時(shí)間來(lái)完善。

參考文章來(lái)電秀實(shí)現(xiàn)

實(shí)現(xiàn)思想

通過(guò)監(jiān)聽手機(jī)Service 分辨來(lái)電狀態(tài)，然后彈出我們自定義的來(lái)電頁(yè)面，覆蓋系統(tǒng)來(lái)電頁(yè)面。
通過(guò)相關(guān)API （主要兩種：讀取來(lái)電系統(tǒng)的Notification信息和模擬耳機(jī)線控的方式進(jìn)行掛斷/接聽）實(shí)現(xiàn)接聽和掛斷功能。我這里會(huì)使用兩種（低版本使用電話狀態(tài)廣播監(jiān)聽，高版本使用InCallService）監(jiān)聽電話狀態(tài)的Service 及兩種界面展示來(lái)呈現(xiàn)來(lái)電信息，多個(gè)界面和多個(gè)Service的監(jiān)聽能夠增加高版本的容錯(cuò)率兼容性。
實(shí)現(xiàn)自定義的撥號(hào)界面或者直接使用系統(tǒng)的撥號(hào)界面。

注意：因?yàn)槠鶈?wèn)題，博客只會(huì)截取部分代碼，太長(zhǎng)讀者很難讀下去，Demo已經(jīng)調(diào)試通過(guò)，如果有想看源碼的可以移步到我的 GitHub項(xiàng)目地址

申請(qǐng)權(quán)限

靜態(tài)權(quán)限

電話應(yīng)用，會(huì)用到很多權(quán)限，我這里盡可能多的靜態(tài)注冊(cè)了一些權(quán)限，如果引入項(xiàng)目中，需要甄別下，代碼如下：

動(dòng)態(tài)權(quán)限

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

上述代碼，為自己測(cè)試使用的Demo，所以請(qǐng)求權(quán)限直接請(qǐng)求分組中的全部權(quán)限了，項(xiàng)目中根據(jù)需要?jiǎng)討B(tài)申請(qǐng)部分權(quán)限

雖然我們已經(jīng)申請(qǐng)了這么多權(quán)限，但是為了能夠替換系統(tǒng)電話界面成功，還有一部分權(quán)限是需要通過(guò)彈框來(lái)引導(dǎo)用戶去設(shè)置中開啟的。

// 暫時(shí)把重要代碼cv出來(lái)了一部分，建議下載Demo源碼 ，結(jié)合博客一起觀看

上述代碼主要羅列了需要引導(dǎo)用戶開啟部分設(shè)置權(quán)限的核心代碼和方法。

監(jiān)聽電話

對(duì)于監(jiān)聽電話這塊，會(huì)有很多兼容性的問(wèn)題，我們這里先使用廣播監(jiān)聽 action = android.intent.action.PHONE_STATE 的廣播，然后根據(jù)狀態(tài)調(diào)用起來(lái)懸浮窗。但是測(cè)試Android高版本手機(jī) 發(fā)現(xiàn) InCallService 會(huì)更好的獲取到電話狀態(tài)，所以我這里的處理方案是兩個(gè)方案都保存在了代碼中，最后通過(guò)調(diào)用不同的界面來(lái)區(qū)分。

BroadcastReceiver +懸浮窗顯示實(shí)現(xiàn)

                    val phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER)
                    if (Intent.ACTION_NEW_OUTGOING_CALL.equals(action, true)) {
                        state = 1000
                    }
                    dealWithCallAction(state, phoneNumber)

                PhoneStateActionImpl.instance.onCallOut(phoneNumber)
            }
        }
    }
}

獲取到廣播的信息后我們就可以著手懸浮窗的繪制和初始化工作

// 部分代碼省略

懸浮窗展示完成后，就要設(shè)置電話接通和掛斷的操作（注意：這里很多低版本手機(jī)存在兼容問(wèn)題，所以會(huì)有一些代碼比較奇怪）

# 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()
        }
    }

以上代碼為接口實(shí)現(xiàn)類，我們這里會(huì)跳轉(zhuǎn)到一個(gè)前臺(tái)Activity（一定程度上可以將App拉活），主要邏輯我們放在自己的前臺(tái)Service中操作。

# CallListenerService.kt
// Andorid新版本 啟動(dòng)服務(wù)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()
        }
    }

為保證我們的服務(wù)能夠正常吊起來(lái)，吊起前臺(tái)服務(wù)，并設(shè)置Service等級(jí)，代碼如下：

# AndroidManifest.xml
<!-- 電話狀態(tài)接收廣播 -->
        <service
            android:name=".phone.service.CallListenerService"
            android:enabled="true"

            <intent-filter android:priority="1000">
                <action android:name="com.maiya.call.phone.service.CallListenerService" />
            </intent-filter>
        </service>
<!-- 監(jiān)聽通知欄權(quán)限 必備 -->
<service
            android:name=".phone.service.NotificationService"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">

                <action android:name="android.service.notification.NotificationListenerService" />
            </intent-filter>
        </service>

低版本的接通和掛斷電話，因?yàn)樾枰嫒莶糠謾C(jī)型，所以我們會(huì)有比較多的判斷，代碼如下：

到這里中低版本的電話接通和掛斷，基本已經(jīng)完畢。下一步我們主要寫，用戶在同意設(shè)置應(yīng)用為默認(rèn)電話應(yīng)用后的更加簡(jiǎn)單方便的實(shí)現(xiàn)方式。

InCallService + Activity實(shí)現(xiàn)

在使用 InCallService 服務(wù)的同時(shí)，需要設(shè)置該應(yīng)用為默認(rèn)撥號(hào)應(yīng)用（這里只說(shuō)明技術(shù)的可能性，不對(duì)用戶行為分析）。

# AndroidManifest.xml

            App.context.startService(intent)
        }

            it.registerCallback(callback)
            PhoneCallManager.instance.addCall(it)
        }
    }

            }
        }
        return super.onStartCommand(intent, flags, startId)
    }
}

以上為InCallService的代碼。部分方法進(jìn)行了說(shuō)明。

# PhoneCallManager.kt

                true
            } ?: false
    /**

                it.disconnect()
                true
            } ?: false

由于篇幅問(wèn)題，PhoneCallManager中的代碼不全部展示，需要的小伙伴請(qǐng)移步Github，該類中主要進(jìn)行了一些默認(rèn)撥號(hào)應(yīng)用，呼叫Call是否保持等一些操作。
