Question

Hai iam刚开始使用广播接收器进行Android开发...我的应用程序有一个广播接收器和一个类（ MyPhoneStateListener.java ），它扩展了 PhoneStateListener 通知来电的电话号码。这里的问题是我在MyPhoneStateListener.java中有一个Log.d（“no”，msg）语句来查看logcat中的传入呼叫号码。当我第一次启动我的应用程序并进行测试时，电话号码会显示一次就好了，当我第二次测试时，电话号码显示三次（语句或类别可能会被执行3次），当我再次测试时，电话号码会显示5次等等...我在下面发布了我的代码，请检查并帮我解决。

BroadReceiver.java

package com.vibrator;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
//import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
//import android.widget.Toast;

public class BroadReceiver extends BroadcastReceiver{



        public void onReceive(Context context, Intent intent) {

        try {
                   // TELEPHONY MANAGER class object to register one listner
                    TelephonyManager tmgr = (TelephonyManager) context
                            .getSystemService(Context.TELEPHONY_SERVICE);

                    //Create Listner
                    MyPhoneStateListener PhoneListener = new MyPhoneStateListener();

                    // Register listener for LISTEN_CALL_STATE
                    tmgr.listen(PhoneListener, PhoneStateListener.LISTEN_CALL_STATE);

            } catch (Exception e) {
                Log.e("Phone Receive Error", " " + e);
            }
        }

MyPhoneStateListener.java

package com.vibrator;
import android.telephony.PhoneStateListener;
import android.util.Log;

    public class MyPhoneStateListener extends PhoneStateListener {

            public void onCallStateChanged(int state, String incomingNumber) {

               // Log.d("MyPhoneListener",state+"   incoming no:"+incomingNumber);
               //if the call state is ringing(i.e state=1) then if statements executes
                if (state == 1) {

                    String msg = "New Phone Call Event. Incomming Number : "+incomingNumber;
                    Log.d("no", msg);

                }
            }
        }


    }

logcat的：
