围栅状态的感知API查询

Question

我正在尝试使用Awareness API获取fence状态。这是关于此的documentation。但是......使用时：

Awareness.FenceApi.queryFences

我可以看到它的deprecated，而是需要使用：

Awareness.getFenceClient

有谁能请举例说明如何使用getFenceClient获取围栏状态？

Answer 1

知道了：

Awareness.getFenceClient(context).queryFences(FenceQueryRequest.forFences(Arrays.asList(key)))
            .addOnSuccessListener(new OnSuccessListener<FenceQueryResponse>() {

                @Override
                public void onSuccess(FenceQueryResponse fenceQueryResponse) {

                    FenceStateMap map = fenceQueryResponse.getFenceStateMap();

                    for (String fenceKey : map.getFenceKeys()) {
                        FenceState fenceState = map.getFenceState(fenceKey);
                        Log.i(TAG, "Fence " + fenceKey + ": "
                                + fenceState.getCurrentState()
                                + ", was="
                                + fenceState.getPreviousState());
                    }
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {

                    Log.d(TAG, "Failed: " + e);
                }
            });
