设置间隔

package com.gochequan.hzlc.widget;

import android.graphics.Rect;
import android.support.v7.widget.RecyclerView;
import android.view.View;

/**
*
* 自定义RecyclerView的item之间的间距
*/

public class RecyclerViewSpaceItemDecoration extends RecyclerView.ItemDecoration {
private int space;

public RecyclerViewSpaceItemDecoration(int space) {
    this.space = space;
}

@Override
public void getItemOffsets(Rect outRect, View view,
                           RecyclerView parent, RecyclerView.State state) {
    outRect.right = space;
    outRect.bottom = space;

}
}

  mRecyclerView.addItemDecoration(new RecyclerViewSpaceItemDecoration(0));

设置不要上滑效果

android:overScrollMode="never"

设置禁止滑动

 recyclerview.setnestedscrollingenabled(false);//禁止rcyc嵌套滑动
