当电话在android中响铃时，我想以编程方式获取电话号码

Question

我想要来电者的号码，因为手机在 Android 中响起。由于“TelephonyManager”的“EXTRA_INCOMING_NUMBER”常量现在已被弃用，我不知道如何获得相同的功能。我用谷歌搜索并了解了“通话记录”上下文，但它不能完成相同的工作，因为它可以让您访问通话记录中的号码，但我想要电话响铃时的号码。

Answer 1

对于 Android >= 29，您应该使用

CallScreeningService

代替。官方文档：

• 屏幕通话
• 呼叫筛选服务

以下是对我有用的步骤：

1. 声明

   MyCallScreeningService

   扩展

   CallScreeningService

class MyCallScreeningService : CallScreeningService() {
    override fun onScreenCall(callDetails: Call.Details) {
        // Check if call is incoming and get the phone number
        Log.d("MyCallScreeningService", "onScreenCall")
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            if (callDetails.callDirection == Call.Details.DIRECTION_INCOMING) {
                val incomingNumber = extractPhoneNumber(callDetails)
                Log.d("MyCallScreeningService", "Incoming Call = $incomingNumber")
                val callResponse = CallResponse.Builder()
                    .setDisallowCall(false)
                    .setDisallowCall(false)
                    .setRejectCall(false)
                    .setSkipCallLog(false)
                    .setSkipNotification(false)
                    .build()
                // call this to notify user immediately, otherwise there will be a delay
                respondToCall(callDetails, callResponse)
            }
        }
    }

    private fun extractPhoneNumber(callDetails: Call.Details): String? {
        val handle = callDetails.handle
        if (handle != null) {
            // Attempt to extract phone number from the handle
            return handle.schemeSpecificPart
        } else {
            // Handle is null, try other methods if available
            val gatewayInfo = callDetails.gatewayInfo
            if (gatewayInfo != null) {
                return gatewayInfo.originalAddress.schemeSpecificPart
            }
        }
        return null
    }

}

2. 将

   MyCallScreeningService

   添加到 AndroidManifest.xml

<service android:name=".MyCallScreeningService"
    android:exported="true"
    android:permission="android.permission.BIND_SCREENING_SERVICE">
    <intent-filter>
        <action android:name="android.telecom.CallScreeningService" />
    </intent-filter>
</service>

3. 在您的

   MainActivity

   或其他活动中请求角色并绑定服务：

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            val roleManager = getSystemService(ROLE_SERVICE) as RoleManager
            val intent = roleManager.createRequestRoleIntent(RoleManager.ROLE_CALL_SCREENING)
            val startForRequestRoleResult = registerForActivityResult(
                ActivityResultContracts.StartActivityForResult()
            ) { result: androidx.activity.result.ActivityResult ->
                if (result.resultCode == Activity.RESULT_OK) {
                    //  you will get result here in result.data
                    bindMyService()
                }
            }
            startForRequestRoleResult.launch(intent)
        }
    }

    private fun bindMyService(){
        Log.i("MainActivity", "binding my service")
        val mCallServiceIntent = Intent("android.telecom.CallScreeningService")
        mCallServiceIntent.setPackage(applicationContext.packageName)
        val mServiceConnection: ServiceConnection = object : ServiceConnection {
            override fun onServiceConnected(componentName: ComponentName, iBinder: IBinder) {
                // iBinder is an instance of CallScreeningService.CallScreenBinder
                // CallScreenBinder is an inner class present inside CallScreenService
            }
            override fun onServiceDisconnected(componentName: ComponentName) {}
            override fun onBindingDied(name: ComponentName) {}
        }
        bindService(mCallServiceIntent, mServiceConnection, BIND_AUTO_CREATE)
    }
}
