펜스 상태 쿼리
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
펜스의 현재 상태를 쿼리하려면 FenceClient.queryFences()
를 호출하고 쿼리할 펜스의 펜스 키를 전달합니다.
다음 예에서는 FenceClient.queryFences()
를 호출하여 FenceStateMap
를 가져온 다음 FenceStateMap
를 사용하여 FenceState
값을 반환하여 현재 상태, 이전 상태, 울타리가 마지막으로 업데이트된 시간을 표시합니다.
protected void queryFence(final String fenceKey) {
Awareness.getFenceClient(this)
.queryFences(FenceQueryRequest.forFences(Arrays.asList(fenceKey)))
.addOnSuccessListener(new OnSuccessListener<FenceQueryResponse>() {
@Override
public void onSuccess(FenceQueryResponse response) {
FenceStateMap map = response.getFenceStateMap();
for (String fenceKey : map.getFenceKeys()) {
FenceState fenceState = map.getFenceState(fenceKey);
Log.i(TAG, "Fence " + fenceKey + ": "
+ fenceState.getCurrentState()
+ ", was="
+ fenceState.getPreviousState()
+ ", lastUpdateTime="
+ DATE_FORMAT.format(
new Date(fenceState.getLastFenceUpdateTimeMillis())));
}
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.e(TAG, "Could not query fence: " + fenceKey);
return;
}
});
}
