如何在android中删除Recyclerview项目之间的分隔符

我想删除RecyclerView项目之间的分隔符(空格)

因此,尝试设置background项目视图和RecyclerView到White,但它不工作怎么解决？

物品查看XML:

活动XML:

Activity 课程:

    rv_categories.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
    rv_categories.setItemAnimator(new DefaultItemAnimator());

首先定义您的RecyclerView:

RecyclerView recycle =(RecyclerView)findViewById(R.id.recyclerView);

并在您的活动中使用此方法:

recycle.addItemDecoration(new DividerItemDecoration(context, 0));

您可以使用DividerItemDecoration类并覆盖其onDraw方法,不执行任何操作:

mRecyclerView.addItemDecoration(new DividerItemDecoration(mContext, LinearLayoutManager.VERTICAL) {
        @Override
        public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
            // Do not draw the divider
        }
    });
