问题描述
我已经为这样的项目设置了负边距:-
I have set the negative margin for items like this:-
ItemDecoration.java
public class ItemDecorator extends RecyclerView.ItemDecoration {
private final int mSpace;
public ItemDecorator(int space) {
this.mSpace = space;
}
@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
int position = parent.getChildAdapterPosition(view);
if (position != 0)
outRect.top = mSpace;
}
}
MainActivity.java
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.addItemDecoration(new ItemDecorator(-80));
这会导致顶部项目与顶部项目重叠后堆叠最低和下一个项目.我希望顶部项目与其下一个项目重叠,依此类推.
This causes top item to stack lowest and next item after the top item overlaps it. I want top item to overlap its next item and so on.
当前视图
必需的视图
推荐答案
试试这种方式,并以相反的方向渲染你的回收器视图.
Try this way and render your recycler view in reverse direction.
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setReverseLayout(true);
layoutManager.setStackFromEnd(true);
recyclerView.setLayoutManager(layoutManager);
