Question

我正在android中构建一个应用程序，当我的手机中有任何电话时，它将执行一个动作。我用广播接收器和电话状态监听器试过这个。但它没有用。如果我使用活动，那么手机状态监听器工作得很好，但它不适用于广播接收器。我做错了什么？请任何身体帮助......

谢谢＆amp;问候

Answer 1

<receiver android:name="ClassName">
   <intent-filter>             
 <action android:name="android.intent.action.PHONE_STATE">/action>
  </intent-filter>
 </receiver>

它的工作!!

以下是a Chinese BBS的示例。

public class PhoneStatReceiver extends BroadcastReceiver{        

        private static final String TAG = "PhoneStatReceiver"; 

        private static boolean incomingFlag = false;

        private static String incoming_number = null;



        @Override

        public void onReceive(Context context, Intent intent) {

                //如果是拨打电话

                if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){                        

                        incomingFlag = false;

                        String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);        

                        Log.i(TAG, "call OUT:"+phoneNumber);                        

                }else{                        

                        //如果是来电

                        TelephonyManager tm = 

                            (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);                        



                        switch (tm.getCallState()) {

                        case TelephonyManager.CALL_STATE_RINGING:

                                incomingFlag = true;//标识当前是来电

                                incoming_number = intent.getStringExtra("incoming_number");

                                Log.i(TAG, "RINGING :"+ incoming_number);

                                break;

                                if(incomingFlag){

                                        Log.i(TAG, "incoming ACCEPT :"+ incoming_number);

                                }

                                break;



                        case TelephonyManager.CALL_STATE_IDLE:                                

                                if(incomingFlag){

                                }

                                break;

                        }

Answer 4

我在这里读过 https://gist.github.com/ftvs/e61ccb039f511eb288ee

对我来说很好。 Android版本5.0。

接下来是我的任务。

我的应用程序必须观察所有调用事件。并区分呼入，呼出电话。来电完成后，必须随时创建新的来电。设置号码中指定的电话号码。此电话号码是门禁控制器的号码。（https://www.pal-es.com/3g-eng）它为为用户打开自动门而不是在白名单中作弊。此应用程序可在独立的智能手机中使用，仅用于完成此任务。

一些功能也可以在这里找到。

Answer 6

我最初经历了同样的事情但后来我将以下权限添加到我的清单。

    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

当然，在我的代码中，当我接到电话时，我正在显示一个祝酒词。因此，您可能需要添加与您的要求相对应的其他权限。
