    <BackgroundView>        
    <ForegroundView>

    adapter.onItemSwiped(viewHolder);
}

@Override
public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder,
                        float dX, float dY, int actionState, boolean isCurrentlyActive) {

    View foregroundView = ((myViewHolder)viewHolder).getForegroundView();
    getDefaultUIUtil().onDraw(c, recyclerView, foregroundView, dX, dY, actionState, isCurrentlyActive);

    //getSwipeLimit() used below returns the width of the delete icon
    float translationX = Math.min(-dX, ((myViewHolder) viewHolder).getSwipeLimit());
    foregroundView.setTranslationX(-translationX);
}

我在BindViewHolder我的适配器类中为backgroundview设置了一个单击侦听器.

@Override
public void onBindViewHolder(WhiteListViewHolder holder, Cursor cursor) {
    //get name …
