BroadcastReceiver中的撥入和撥出電話

Question

有一項服務，處理的媒體播放器希望爲接收和撥出的呼叫服務停止的媒體播放器執行此操作，並在呼叫流程結束時繼續播放。 現在只設法停止傳入和傳出呼叫的回放，應該添加代碼來播放TelephonyManager.CALL_STATE_IDLE：然後在音樂開始一段時間後通話，如何解決它？

public class CallReceiver extends BroadcastReceiver{ 
TelephonyManager telManager; 
Context context; 
boolean startedCall = false; 

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


this.context=context; 


telManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 
telManager.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE); 

} 

private final PhoneStateListener phoneListener = new PhoneStateListener() { 
@Override 
public void onCallStateChanged(int state, String incomingNumber) { 
    super.onCallStateChanged(state, incomingNumber); 
    try { 
     switch (state) { 
     case TelephonyManager.CALL_STATE_RINGING: { 
      if(incomingNumber!=null) 
      { 
       //incoming call 
       MediaService.stopMP(); 
       startedCall = true; 
      } 

     break; 
     } 
     case TelephonyManager.CALL_STATE_OFFHOOK: { 
      if(incomingNumber!=null) 
      { 
       //outgoing call 
       MediaService.stopMP(); 
       startedCall = true; 
      } 

     break; 
     } 
     case TelephonyManager.CALL_STATE_IDLE: { 
      if(startedCall) 
      { 
       MainActivity.titleMusic.setVisibility(View.VISIBLE); 
       MainActivity.Play(); 
       MediaService.startMP(); 
       startedCall = false; 
      }     

     break; 
     } 
     default: { } 
     } 
     } catch (Exception ex) { 

     } 
    } 
}; 
}

每當前振鈴呼叫狀態應該是TelephonyManager.CALL_STATE_IDLE，之前獲得來電通話狀態應該是IDEL，所以，你必須設置一個標誌布爾值確定的狀態;

public class CallReceiver extends BroadcastReceiver{ 
    TelephonyManager telManager; 
    Context context; 

    @Override 
    public void onReceive(Context context, Intent intent) {  
     this.context=context;  
     private boolean startedCall = false; // New added boolean  
     telManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 
     telManager.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);  
    } 

    private final PhoneStateListener phoneListener = new PhoneStateListener() { 
    @Override 
    public void onCallStateChanged(int state, String incomingNumber) { 
    super.onCallStateChanged(state, incomingNumber); 
    try { 
     switch (state) { 
      case TelephonyManager.CALL_STATE_RINGING: { 
       if(incomingNumber!=null) { 
        //incoming call 
        MainActivity.stopMP() 
       }  
       break; 
      } 
      case TelephonyManager.CALL_STATE_OFFHOOK: {  
       startedCall = true; // Newly added code  
       if(incomingNumber!=null) { 
        //outgoing call 
        MainActivity.stopMP(); 
       } 
       break; 
      } 
      case TelephonyManager.CALL_STATE_IDLE: { 
       if(startedCall) { 
        MainActivity.titleMusic.setVisibility(View.VISIBLE); 
        MainActivity.Play(); 
        MediaService.startMP(); 
       }   
       break; 
      } 
      default: { } 
     } 
     } catch (Exception ex) { 

     } 
    } 
    }; 
}
