問題:

RecyclerView去除底部分割線

解決方式：

參照DividerItemDecoration重寫一個類，重寫方法：

public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        if (this.mDivider == null) {
            outRect.set(0, 0, 0, 0);
        } else {
            if (this.mOrientation == 1) {
                int lastPosition = state.getItemCount() - 1;
                int position = parent.getChildAdapterPosition(view);
                if (position < lastPosition) {
                    outRect.set(0, 0, 0, mDivider.getIntrinsicHeight());
                } else {
                    outRect.set(0, 0, 0, 0);
                }
            } else {
                int lastPosition = state.getItemCount() - 1;
                int position = parent.getChildAdapterPosition(view);
                if (position < lastPosition) {
                    outRect.set(0, 0, mDivider.getIntrinsicWidth(), 0);
                } else {
                    outRect.set(0, 0, 0, 0);
                }
            }
        }
    }
