如何查找是否已在android

Question

中接聽電話我只想在撥出電話已接聽時啓動計時器。像Nexus 5中的默認電話應用程序一樣。

有沒有方法可以確定電話是否已被回答？

電話號碼被撥打後，我立即嘗試了電話聽衆，它得到CALL_STATE_OFFHOOK。所以這不是正確的方法？

有人能幫我弄清楚這個嗎？

謝謝！

可能這一個幫助你：

public class CallLogReceiver extends BroadcastReceiver { 

static boolean missedCall, incomingCall; 

@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO Auto-generated method stub 


    if (intent.getAction().equals("android.intent.action.PHONE_STATE")) { 
     String state = intent.getExtras().getString(
       TelephonyManager.EXTRA_STATE); 

     if ((state != null) 
       && (state.equals(TelephonyManager.EXTRA_STATE_RINGING))) { 
      CallLogReceiver.phoneNo = intent.getExtras().getString(
        "incoming_number"); 
      CallLogReceiver.missedCall = true; 
     } 

     if ((state != null) 
       && (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))) { 
      CallLogReceiver.incomingCall = true; 

     } 
     if (state != null 
       && !(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) 
       && !(state.equals(TelephonyManager.EXTRA_STATE_RINGING))) { 

      if (CallLogReceiver.missedCall && CallLogReceiver.incomingCall) { 
       //incoming call logic 
      } 

      else if (CallLogReceiver.missedCall 
        && !CallLogReceiver.incomingCall) { 
       // missed call logic 
      } 
      CallLogReceiver.missedCall = CallLogReceiver.incomingCall = false; 
     } 
     } 
    } 
}
