在PickList AdaptiveTrackSelection中删除“无”选项

Question

如何从选择列表中删除“无”选项，任何提示将不胜感激！ 这是我的代码，用于从URL获取支持的比特率。

    MappingTrackSelector.MappedTrackInfo mappedTrackInfo = selector.getCurrentMappedTrackInfo();
    if (mappedTrackInfo != null) {
        int rendererIndex = 0;
        int rendererType = mappedTrackInfo.getRendererType(rendererIndex);
        boolean allowAdaptiveSelections =
                rendererType == C.TRACK_TYPE_VIDEO
                        || (rendererType == C.TRACK_TYPE_AUDIO
                        && mappedTrackInfo.getTypeSupport(C.TRACK_TYPE_VIDEO)
                        == MappingTrackSelector.MappedTrackInfo.RENDERER_SUPPORT_NO_TRACKS);
        Pair<AlertDialog, TrackSelectionView> dialogPair =
                TrackSelectionView.getDialog(VideoStream.this, "Available Quality", (DefaultTrackSelector) selector, rendererIndex);
        dialogPair.second.setShowDisableOption(true);
        dialogPair.second.setAllowAdaptiveSelections(allowAdaptiveSelections);
        dialogPair.first.show();
    }

可以通过删除以下行来完成。

dialogPair.second.setShowDisableOption（true）;
