使用RecyclerView时如何去除底部的分割线

private void drawHorizontal(Canvas c, RecyclerView parent, State state) { int childCount = parent.getChildCount() - 1; int left = 0; int top = parent.getPaddingTop(); int right = 0; int bottom = parent.getHeight() - parent.getPaddingBottom(); for (int i = 0; i < childCount; i++) { View view = parent.getChildAt(i); RecyclerView.LayoutParams params = (LayoutParams) view.getLayoutParams(); //考虑，padding left = view.getRight(); right = left + divider.getIntrinsicHeight(); //我们在自定义drawable的是是，写死了高度，所以只能用高度 divider.setBounds(left, top, right, bottom); divider.draw(c); }}private void drawVertical(Canvas c, RecyclerView parent, State state) { int childCount = parent.getChildCount() - 1; int left = parent.getPaddingLeft(); int top = 0; int right = parent.getWidth() - parent.getPaddingRight(); //考虑右边的padding int bottom = 0; for (int i = 0; i < childCount; i++) { //不绘制最后一个条目的分割线 View view = parent.getChildAt(i); RecyclerView.LayoutParams params = (LayoutParams) view.getLayoutParams(); //考虑，padding top = view.getBottom() + params.topMargin; //就是当前view底部到顶部的距离 bottom = top + divider.getIntrinsicHeight() - params.bottomMargin; //就是top+divider高度 divider.setBounds(left, top, right, bottom); divider.draw(c); }}@Overridepublic void getItemOffsets(Rect outRect, View view, RecyclerView parent, State state) { int childAdapterPosition = parent.getChildAdapterPosition(view); int lastCount = parent.getAdapter().getItemCount() - 1; //如果当前条目与是最后一个条目，就不设置divider padding if (childAdapterPosition == lastCount) { outRect.set(0, 0, 0, 0); return; } Log.d("TAG", childAdapterPosition + "," + lastCount); if (orientation == LinearLayoutCompat.HORIZONTAL) { outRect.set(0, 0, divider.getIntrinsicHeight(), 0); //0,0,30,0，设置宽度 } else { outRect.set(0, 0, 0, divider.getIntrinsicHeight()); //0,0,0,30，设置高度 }}
