廣播接收器和phonestatelistener

我想使用BroadcastReceiver來接收來電。我想在通話結束時註冊通話。下面的代碼給出了每個狀態（空閒，振鈴和摘機）不止一次與相同的號碼（它不是過去的呼叫問題）。是否因爲phonestatelistner在服務中被調用？廣播接收器和phonestatelistener

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); 
    } 

    }

我也試圖與phonestatelistener同樣的事情在一個單獨的類，但它不會被調用，即我的代碼沒有達到那裏。在我的清單文件中，我已經註冊了接收者，但是沒有phonestatelistener的聲明。那是要註冊嗎？

如果解決方案非常明顯，但對於Android的新東西，我很抱歉。任何幫助表示讚賞:)

確保你打開你的應用程序在您安裝它之後。在用戶明確打開應用程序之前，應用程序處於停止狀態。請參閱：http://stackoverflow.com/a/9955247/786462 這可以使它看起來像你的BroadcastReceiver沒有被調用。 – DataDino

是，選擇收聽或接收，不是他們兩個
