서비스를 통해 생성하는보기를 추가하려고합니다. 사용중인 코드는 앱 상태에 관계없이 항상 표시되는 Facebook Chatheads을 기반으로합니다. 그들은 또한 너무 다른 것 위에 표시됩니다 :항상 보이는 채팅 헤드의 LayoutParams가 항상 표시되지는 않습니다.
내가 지금 활성 응용 프로그램에 채팅 헤드를 제한하고 싶습니다. 특히 Window.LayoutParams를 TYPE_PHONE에서 TYPE_DRAWN_APPLICATION으로 변경할 때마다 Bad Token Exception을 처리하고 있습니다.
MY QUESTION : 올바른 창 토큰을 LayoutParams에 전달해야하지만이 작업을 올바르게 수행하는 방법을 찾을 수없는 것으로 알고 있습니다. 모든 조언을 높이 평가 될 것입니다. 여기
내 코드입니다 :// 주요 활동
private void addNewBubble() {
BubbleLayout bubbleView = (BubbleLayout)LayoutInflater.from(MainActivity.this).inflate(R.layout.bubble_layout, null);
bubblesManager.addBubble(bubbleView, 60, 20);
}
// initializes Bubbles Manager
private void initializeBubblesManager() {
bubblesManager = new BubblesManager.Builder(this)
.setTrashLayout(R.layout.task_bubble_trash_layout)
.setInitializationCallback(new OnInitializedCallback() {
@Override
public void onInitialized() {
addNewBubble(); // Called when addNewBubble is initialized and the bubble data is loaded. When used on devices running API 18 or below, this function is always called.
}
})
.build();
bubblesManager.initialize();
}

I 앱이 일시 정지에 때 화면에 남아있는없이 응용 프로그램 창에 채팅 헤드를 제한 할 수 방법에 대한 조언을받는 건가요?

왜 '서비스'를 연장하겠습니까? –
좋은 질문입니다. 서비스를 확장하면 BubblesService를 우리가 창에 바인딩 할 수있는 서비스로 실행할 수 있다고 생각하십니까? – Z101
좋은 추측. 이를 위해'BubblesService'를 시작하고'addBubble'에 액세스하기 전에 UI 컴포넌트를 바인딩해야합니다. –
