RecyclerView 条目布局宽度设置match_parent无效果的问题解决
这里为了解决recycleview不能撑满全屏的问题，这里layoutManager不管你布局里是否设置，都不准确，所以需要在代码里重新设置MATCH_PARENT

LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity()) {
            @Override
            public RecyclerView.LayoutParams generateDefaultLayoutParams() {
                return new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                        ViewGroup.LayoutParams.WRAP_CONTENT);
            }
        };

recyclerView.setLayoutManager(layoutManager);
