如何識別是否收到傳出呼叫的電話狀態或不

走出去通話開始，
的走出去，在接電話接收端和
的走出去電話掛斷

我能夠獲得來電通話事件，但不能撥打電話事件。

這是我的代碼，請找出我的問題並給出解決方案。

由於提前

@Override 
public void onReceive(Context context, Intent intent) { 

    // We listen to two intents. The new outgoing call only tells us of an 
    // outgoing call. We use it to get the number. 
    if (intent.getAction() 
      .equals("android.intent.action.NEW_OUTGOING_CALL")) { 
     savedNumber = intent.getExtras() 
       .getString("android.intent.extra.PHONE_NUMBER"); 
    } else { 
     String stateStr = intent.getExtras() 
       .getString(TelephonyManager.EXTRA_STATE); 
     String number = intent.getExtras() 
       .getString(TelephonyManager.EXTRA_INCOMING_NUMBER); 
     int state = 0; 
     if (stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE)) { 
      state = TelephonyManager.CALL_STATE_IDLE; 
     } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) { 
      state = TelephonyManager.CALL_STATE_OFFHOOK; 
     } else if (stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING)) { 
      state = TelephonyManager.CALL_STATE_RINGING; 
     } 

     onCallStateChanged(context, state, number); 
    } 
}

下面的代碼幫助你獲得的淨工作狀態代碼的onCreate

StateListener phoneStateListener = new StateListener(); 
TelephonyManager telephonyManager =(TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
telephonyManager.listen(phoneStateListener,PhoneStateListener.LISTEN_CALL_STATE);

聽電話的狀態來創建一個內部類。清單文件

class StateListener extends PhoneStateListener { 
@Override 
public void onCallStateChanged(int state, String incomingNumber) { 
super.onCallStateChanged(state, incomingNumber); 
switch (state) { 
    case TelephonyManager.CALL_STATE_RINGING: 
     break; 
    case TelephonyManager.CALL_STATE_OFFHOOK: 
     System.out.println("call Activity off hook"); 
     LockScreenActivity.this.finish(); 
     break; 
    case TelephonyManager.CALL_STATE_IDLE: 
     break; 
} 
} 
};

設置權限

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

1）走出去通話開始，

您可以識別是否呼出開始不使用下面的代碼

 case TelephonyManager.CALL_STATE_RINGING: 
      isIncoming = true; 
      callStartTime = new Date(); 
      savedNumber = number; 
      onIncomingCallReceived(context, number, callStartTime); 
      break; 
     case TelephonyManager.CALL_STATE_OFFHOOK: 
      //Transition of ringing->offhook are pickups of incoming calls. Nothing done on them 
      if (lastState != TelephonyManager.CALL_STATE_RINGING) { 
       isIncoming = false; 
       callStartTime = new Date(); 
       startRecording(context,"_Out_",number); 
       onOutgoingCallStarted(context, savedNumber, callStartTime); 
      } 
      else 
      { 
       isIncoming = true; 
       callStartTime = new Date(); 
       startRecording(context,"_In_",savedNumber); 
       onIncomingCallAnswered(context, number, callStartTime); 
      } 

      break;

2）走出去的呼叫在接收端和 3）收到走出去電話掛斷

但是你無法識別來電轉接至另一端拿起通過使用任何直接的API爲Android不提供任何直接的API來檢測。
