Question

我正在尝试使用BroadcastReceiver来接收来电。我希望在通话结束时注册通话。下面的代码使用相同的数字（不是过去调用的问题）给出了每个状态（空闲，响铃n摘机）不止一次。是因为在服务中调用了phonestatelistner。

 public class IncomingCallReceiver extends BroadcastReceiver {

 int stateString =0;
 int prevStat = 0;

    @Override
    public void onReceive(Context context, Intent intent) {
            Bundle bundle = intent.getExtras();

            if(null == bundle)
                    return;

            String state = bundle.getString(TelephonyManager.EXTRA_STATE);

            if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
            {
                    String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);

                   String info = "Detect Calls sample application\nIncoming number: " + phonenumber;

                    Toast.makeText(context, info, Toast.LENGTH_LONG).show();
            }

            TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
            //CustomPhoneStateListener customPhoneListener = new CustomPhoneStateListener();

            PhoneStateListener listener = new PhoneStateListener() {

            @Override
                public void onCallStateChanged(int state, String incomingNumber) {
                  String p = incomingNumber;
                  switch (state) {
                  case TelephonyManager.CALL_STATE_IDLE:
                    prevStat = stateString;
                    stateString = 1;
                    Log.i("ON CALL STATE CHANGED","IDLE");
                    break;
                  case TelephonyManager.CALL_STATE_OFFHOOK:
                    Log.i("ON CALL STATE CHANGED","OFFFHOOK");
                    prevStat = stateString;
                    stateString = 2;
                    break;
                  case TelephonyManager.CALL_STATE_RINGING:
                    prevStat = stateString;
                    stateString = 3;
                    Log.i("ON CALL STATE CHANGED","RINGING");
                    break;
                  }

                  if(prevStat == 2 && stateString == 1)
                  {
                           Log.i("REGISTER A CALLL","==" +p);
                  }

            }   
            };

               telephony.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
     }

  }

我也尝试使用phonestatelistener在一个单独的类中做同样的事情，但它没有被调用，即我的代码没有到达那里。在我的清单文件中，我已注册接收器，但没有phonestatelistener的声明。这是要注册吗？

我很抱歉，如果解决方案很明显，但对于android事物来说是新手。任何帮助表示赞赏:)

是，选择听众或收到，而不是两者

广播接收器和phonestatelistener
