recyclerview

private ArrayList<String> getdata(){
        ArrayList<String> s = new ArrayList<>();
        for (int i=0;i<50;i++){
            s.add(i+"temp");
        }
        return s;
    }

linearLayoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);

recyclerview侧滑删除（三方SwipeRecyclerView）
1、
侧滑菜单Item点击监听

SwipeMenuItemClickListener mMenuItemClickListener = new SwipeMenuItemClickListener() {
            @Override
            public void onItemClick(SwipeMenuBridge menuBridge) {
                // 任何操作必须先关闭菜单，否则可能出现Item菜单打开状态错乱。
                menuBridge.closeMenu();
                int direction = menuBridge.getDirection(); // 左侧还是右侧菜单。
                int adapterPosition = menuBridge.getAdapterPosition(); // RecyclerView的Item的position。
                Log.i("position",adapterPosition+"");
                strings.remove(adapterPosition);
                myAdapter.notifyItemRemoved(adapterPosition);
                int menuPosition = menuBridge.getPosition(); // 菜单在RecyclerView的Item中的Position。
            }
        };
        lv.setSwipeMenuItemClickListener(mMenuItemClickListener);

2、

//创建菜单
 SwipeMenuCreator menuCreator=new SwipeMenuCreator() {
            @Override
            public void onCreateMenu(SwipeMenu swipeLeftMenu, SwipeMenu swipeRightMenu, int viewType) {
                SwipeMenuItem deleteItem = new SwipeMenuItem(getApplicationContext())
                        .setText("删除")
                        .setTextColor(Color.BLACK)
                        .setWidth(RecyclerView.LayoutParams.MATCH_PARENT)
                        .setHeight(RecyclerView.LayoutParams.MATCH_PARENT)
                       .setBackgroundColor(Color.GREEN);
                swipeRightMenu.addMenuItem(deleteItem); // 在Item左侧添加一个菜单。
            }
        };
        lv.setSwipeMenuCreator(menuCreator);
