활동의 라이프 사이클 정보

Question

public class MyReceiver extends BroadcastReceiver { 
private static IReceiveMessage iReceiveMessage; 
@Override 
public void onReceive(Context context, Intent intent) { 
     iReceiveMessage.receiveMessage(intent.getStringExtra("message")); 
}  
public static void setReceiveMessage(IReceiveMessage iReceiveMessage1) { 
    iReceiveMessage = iReceiveMessage1; 
}} 

public interface IReceiveMessage { 
public void receiveMessage(String message); 
} 




public class MainActivity extends Activity implements IReceiveMessage{ 

    protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
       setContentView(R.layout.main); 
       MyReceiver.setReceiveMessage(this); 

} 
    @Override 
public void onReceiverMessage(String message) { 
Log.i("test", message); 

} 
} 

왜 Myactivity가 종료 된 후에도 Mainactivity는 여전히 메시지를 수신합니까?

Answer 1

당신들의 OnDestroy()에서 활동 등록을 취소 할 필요가

:

protected void onDestroy() { 
     super.onDestroy(); 
     MyReceiver.setReceiveMessage(null); 
}
