setBottomSheetCallback已被弃用。

在使用 ML Kit Firebase 开发对象检测应用程序时，我实现了底部工作表，但它不起作用，因此相机仍然集中在对象上而没有任何结果。代码：

private void setUpBottomSheet() {
    bottomSheetBehavior = BottomSheetBehavior.from(findViewById(R.id.bottom_sheet));
    bottomSheetBehavior.setBottomSheetCallback(
            new BottomSheetBehavior.BottomSheetCallback() {
                @Override
                public void onStateChanged(@NonNull View bottomSheet, int newState) {
                    Log.d(TAG, "Bottom sheet new state: " + newState);
                    bottomSheetScrimView.setVisibility(
                            newState == BottomSheetBehavior.STATE_HIDDEN ? View.GONE : View.VISIBLE);
                    graphicOverlay.clear();

                    switch (newState) {
                        case BottomSheetBehavior.STATE_HIDDEN:
                            workflowModel.setWorkflowState(WorkflowState.DETECTING);
                            break;
                        case BottomSheetBehavior.STATE_COLLAPSED:
                        case BottomSheetBehavior.STATE_EXPANDED:
                        case BottomSheetBehavior.STATE_HALF_EXPANDED:
                            slidingSheetUpFromHiddenState = false;
                            break;
                        case BottomSheetBehavior.STATE_DRAGGING:
                        case BottomSheetBehavior.STATE_SETTLING:
                        default:
                            break;
                    }
                }

                @Override
                public void onSlide(@NonNull View bottomSheet, float slideOffset) {
                    SearchedObject searchedObject = workflowModel.searchedObject.getValue();
                    if (searchedObject == null || Float.isNaN(slideOffset)) {
                        return;
                    }

                    int collapsedStateHeight =
                            Math.min(bottomSheetBehavior.getPeekHeight(), bottomSheet.getHeight());
                    if (slidingSheetUpFromHiddenState) {
                        RectF thumbnailSrcRect =
                                graphicOverlay.translateRect(searchedObject.getBoundingBox());
                        bottomSheetScrimView.updateWithThumbnailTranslateAndScale(
                                objectThumbnailForBottomSheet,
                                collapsedStateHeight,
                                slideOffset,
                                thumbnailSrcRect);

                    } else {
                        bottomSheetScrimView.updateWithThumbnailTranslate(
                                objectThumbnailForBottomSheet, collapsedStateHeight, slideOffset, bottomSheet);
                    }
                }
            });

请使用addBottomSheetCallback和removeBottomSheetCallback代替。
请查看Android文档。
来自文档：

setBottomSheetCallback

此方法已过时。请改用addBottomSheetCallback（BottomSheetCallback）和removeBottomSheetCallback（BottomSheetCallback）。
