이 문제에 관해서는 백만 번 5 가지 질문이 있지만 그 중 모두를 통해 정렬을 시도 했으므로 제대로 작동하지 않습니다. 나는 AppWidgetProvider가 단지 BroadcastReceiver를 확장한다는 것을 안다. 내 AppWidgetProvider 내 모든 것을 다 할 수있다. ACTION_HEADSET_PLUG 인 텐트 필터가 Intent.FLAG_RECEIVER_REGISTERED_ONLY이고 다음과 같이 시도했음을 읽었습니다. Detecting whether a headset is plugged into an Android device or not. 코드에서 내 필터를 설정했지만 예쁜 mish-mash 였기 때문에 머리를 감쌀 수 없었습니다.헤드폰이 연결되어 있는지 확인하십시오. 플러그가 뽑혀 졌을 때 음악을 일시 중지하십시오.
필자의 onReceive 메소드에서 intent.getAction()을 토스트했으며, 헤드폰을 연결하거나 분리 할 때 아무것도 표시되지 않습니다. 버튼을 눌렀을 때, 나는 그들과 연관된 int 상수를 보았습니다. 등록 된 유일한 것에 의해 차단 되었기 때문에 이것이라고 가정합니다.
나는 또한 끈적 거리는 무엇인가에 대해 읽었고, 잠시 동안 그걸 포크로 썼다.

말 그대로 시간이 싸우는 봤는데 그것은 심지어 그 큰 아니기 때문에 정말 바보 같다 : 여기
