SwipeRefreshLayout + RecyclerView 实现的下拉刷新,上拉加载更多

#SwipeRecyclerView SwipeRefreshLayout + RecyclerView 实现的下拉刷新,上拉加载更多

#ScreenShot(效果图是循环播放的,所以感觉有点诡异)

#导航

###1. 支持自动下拉刷新

      设置自动下拉刷新,切记要在recyclerView.setOnLoadListener()之后调用
      因为在没有设置监听接口的情况下,setRefreshing(true),调用不到OnLoadListener
      mSwipeRecyclerView.setRefreshing(true);

###2. 支持emptyView

      mSwipeRecyclerView.setEmptyView(View emptyView);

###3. 支持禁止上拉加载更多/下拉刷新

      //禁止下拉刷新
    mSwipeRecyclerView.setRefreshEnable(false);

    //禁止加载更多
    mSwipeRecyclerView.setLoadMoreEnable(false);

###4.支持自定义footer view

   //设置footerView
   //但是自定义的footerView必须继承BaseFooterView
   mSwipeRecyclerView.setFooterView(new SimpleFooterView(this));

###5.支持GridLayoutManager的SpanSizeLookup

     //由于SwipeRecyclerView中对GridLayoutManager的SpanSizeLookup做了处理,因此对于使用了
    //GridLayoutManager又要使用SpanSizeLookup的情况,可以这样使用!
    mSwipeRecyclerView.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
        @Override
        public int getSpanSize(int position) {
            return 3;
        }
    });

###6.关于footerView的分割线 获取childCount - 1 不包含footerView即可

     //设置去除footerView 的分割线
    mSwipeRecyclerView.getRecyclerView().addItemDecoration(new RecyclerView.ItemDecoration() {
        @Override
        public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
            super.onDraw(c, parent, state);
            Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
            paint.setColor(0xFFEECCCC);

            Rect rect = new Rect();
            int left = parent.getPaddingLeft();
            int right = parent.getWidth() - parent.getPaddingRight();
            final int childCount = parent.getChildCount() - 1;
            for (int i = 0; i < childCount; i++) {
                final View child = parent.getChildAt(i);

                //获得child的布局信息
                final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
                final int top = child.getBottom() + params.bottomMargin;
                final int itemDividerHeight = 1;//px
                rect.set(left + 50, top, right - 50, top + itemDividerHeight);
                c.drawRect(rect, paint);
            }
        }
    });

###7.需要对SwipeRefreshLayout或RecyclerView做其他的设置

      mSwipeRecyclerView.getSwipeRefreshLayout()
      mSwipeRecyclerView.getRecyclerView()

###8.可能存在的问题

    由于Recycler.Adapter中关于数据集更新的方法全是final的,无法重写,并且自定义的DataObserver也没法实现的方法 如:notifyItemMoved方法 因此使用除SwipeRecyclerView中DataObserver的方法之外的更新数据集的方法,可能会有问题所以更新数据集建议采用DataObserver中有的方法。

#Usage

由于并没有放到jCenter

   所以如果需要使用:请自行把layout目录下layout_swipe_recyclerview, layout_footer_view copy跟正常一样控件使用,没有自定义属性

<deadline.swiperecyclerview.SwipeRecyclerView
    android:id="@+id/swipeRecyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
    
mSwipeRecyclerView = (SwipeRecyclerView) findViewById(R.id.swipeRecyclerView);
