将RecyclerView项更改为高于所有其他项

您可以将carousel逻辑与recyclerview组合和snaphelper兼容类一起使用,如下所示:

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fadingEdge="horizontal"
    android:overScrollMode="never"
    android:requiresFadingEdge="horizontal" />

然后将recyclerview附加到snaphelper类:

LinearSnapHelper snapHelper = new LinearSnapHelper();
snapHelper.attachToRecyclerView(recyclerView);

并为当前选定的居中项提供逻辑:

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
        if (newState == RecyclerView.SCROLL_STATE_IDLE) {
            float pos = (float) recyclerView.computeHorizontalScrollOffset() / (float) itemHeight;
            int itemPos = (int) Math.floor(pos);
        }
        super.onScrollStateChanged(recyclerView, newState);
    }
});
