 列表展示是开发过程中经常用到的功能，通常通过 ListView 或者 RecyclerView 控件来实现。在列表显示的过程中可能会碰到这样的需求：需要对列表进行分组，每个分组都有标题 item view 和内容 item view 而且希望列表在滑动的过程中每个分组的标题 item view 可以一直固定的列表的顶部。之前的博客我们已经通过ListView实现了这一功能，有兴趣的可以参考链接[Android分组悬浮列表实现](http://blog.csdn.net/wuyuxing24/article/details/70477566)。but这一次我们通过 RecyclerView 来实现这一需求。实现过程比 ListView 的实现过程要更加简单。 2 | 3 |        在讲怎么实现之前先献上通过RecyclerView实现的效果图 4 | 5 | >LinearLayoutManager实现的效果 6 | 7 | ![LinearLayoutManager实现效果](http://img.blog.csdn.net/20171229093308200?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvd3V5dXhpbmcyNA==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast) 8 | 9 | >GridLayoutManager实现的效果，要固定在顶部的 item要占据整个一行 10 | 11 | ![GridLayoutManager实现效果](http://img.blog.csdn.net/20171229094035994?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvd3V5dXhpbmcyNA==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast) 12 | 13 |        接下来就是实现过程了 14 | 15 |        我们知道 RecyclerView 给提供了一个RecyclerView.ItemDecoration 来给我们使用，这可是好东西呀。RecyclerView.ItemDecoration 从字面上来看是用来给 RecyclerView 里面每个 item 添加装饰用的(当然也可以给RecyclerView的整体添加装饰)。例如，你可以通过 RecyclerView.ItemDecoration 来给 RecyclerView 的每个 item 添加分割线、给每个 item 添加 padding 等等。这里我们通过 RecyclerView.ItemDecoration 来实现 RecyclerView 分组悬浮列表的功能。 16 | 17 |        我们先简单的看下RecyclerView.ItemDecoration里面几个函数： 18 | 19 | ``` 20 | /** 21 | * 可以通过重写这个函数给RecyclerView绘制任意合适的decorations(装饰) 22 | * 会在RecyclerView item绘制之前绘制。可以认为是绘制在RecyclerView的下面 23 | * 会在RecyclerView类的onDraw()里面调用 24 | */ 25 | public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) { 26 | onDraw(c, parent); 27 | } 28 | 29 | /** 30 | * deprecated掉的函数我们不管，忽视掉，不建议使用了 31 | */ 32 | @Deprecated 33 | public void onDraw(Canvas c, RecyclerView parent) { 34 | } 35 | 36 | /** 37 | * 可以通过重写这个函数给RecyclerView绘制任意合适的decorations(装饰) 38 | * 会在RecyclerView item绘制之后绘制。可以认为是绘制在RecyclerView的上面(在上面在盖一层) 39 | * 会在RecyclerView类的super.draw()之后调用, 40 | */ 41 | public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) { 42 | onDrawOver(c, parent); 43 | } 44 | 45 | /** 46 | * deprecated掉的函数不建议使用了，忽视掉 47 | */ 48 | @Deprecated 49 | public void onDrawOver(Canvas c, RecyclerView parent) { 50 | } 51 | 52 | 53 | /** 54 | * deprecated掉的函数不建议使用了，忽视掉 55 | */ 56 | @Deprecated 57 | public void getItemOffsets(Rect outRect, int itemPosition, RecyclerView parent) { 58 | outRect.set(0, 0, 0, 0); 59 | } 60 | 61 | /** 62 | * 给RecyclerView　item对应的每个view增加一些offsets(你可以这么认为item对应的view外面还有一层布局，给这个布局增加padding) 63 | */ 64 | public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) { 65 | getItemOffsets(outRect, ((RecyclerView.LayoutParams) view.getLayoutParams()).getViewLayoutPosition(), parent); 66 | } 67 | ``` 68 | >看到 ItemDecoration 提供到我们的就三个函数了：onDraw()、onDrawOver()、getItemOffsets()。getItemOffsets()函数会在 RecyclerView 里面每个子 view 测量的时候调用，可以用来给每个子 view 添加offset(间距)。onDraw()会在RecyclerView的onDraw()方法里面调用。onDrawOver()函数会在RecyclerView的draw()函数里面调用。关于onDraw()、onDrawOver()两个函数的区分咱们可以简单的认为onDraw()是在RecyclerView绘制内容的时候调用。onDrawOver()是在RecyclerView绘制完内容之后再调用，相当于可以在RecyclerView之上在绘制一层内容。 69 | 70 |        通过对 RecyclerView.ItemDecoration 类的简单分析，再结合我们分组固定标题 View 的需求，我们是要把每个分组的标题 View 固定在顶部，恩，那肯定是在要绘制在RecyclerView层之上的吧，和RecyclerView.ItemDecoration里面的onDrawOver()函数正好对应上了。 71 | 72 |        接下来的事情就好办了 73 | 74 |        首先，既然有些标题是要固定的，那咱们一定要明确的知道哪些position位置对应的view是标题吧，只能通过adapter做文章了，所有我们就有了一个基础的PinnedHeaderAdapter，代码如下： 75 | ``` 76 | public abstract class PinnedHeaderAdapter extends RecyclerView.Adapter { 77 | 78 | /** 79 | * 判断该position对应的位置是要固定 80 | * 81 | * @param position adapter position 82 | * @return true or false 83 | */ 84 | public abstract boolean isPinnedPosition(int position); 85 | 86 | } 87 | ``` 88 |        接下来，RecyclerView.ItemDecoration里面的onDrawOver()函数里面我们做好三件事情就好了:第一，找到当前界面要一直固定在顶部的 View、第二，把找到固定在顶部的 View 画在 RecyclerView 的顶部、第三，当将要到达顶部的标题 View 和已经画在顶部的 View 相遇的时候顶部 view 上移的问题。这三个问题实现起来也不复杂，所以这里我们就直接贴代码了，毕竟代码才是王道吗。 89 | 90 | ``` 91 | /** 92 | * 把要固定的View绘制在上层 93 | */ 94 | @Override 95 | public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) { 96 | super.onDrawOver(c, parent, state); 97 | //确保是PinnedHeaderAdapter的adapter,确保有View 98 | if (parent.getAdapter() instanceof PinnedHeaderAdapter && parent.getChildCount() > 0) { 99 | PinnedHeaderAdapter adapter = (PinnedHeaderAdapter) parent.getAdapter(); 100 | //找到要固定的pin view 101 | View firstView = parent.getChildAt(0); 102 | int firstAdapterPosition = parent.getChildAdapterPosition(firstView); 103 | int pinnedHeaderPosition = getPinnedHeaderViewPosition(firstAdapterPosition, adapter); 104 | if (pinnedHeaderPosition != -1) { 105 | RecyclerView.ViewHolder pinnedHeaderViewHolder = adapter.onCreateViewHolder(parent, adapter.getItemViewType(pinnedHeaderPosition)); 106 | adapter.onBindViewHolder(pinnedHeaderViewHolder, pinnedHeaderPosition); 107 | //要固定的view 108 | View pinnedHeaderView = pinnedHeaderViewHolder.itemView; 109 | ensurePinnedHeaderViewLayout(pinnedHeaderView, parent); 110 | int sectionPinOffset = 0; 111 | for (int index = 0; index < parent.getChildCount(); index++) { 112 | if (adapter.isPinnedPosition(parent.getChildAdapterPosition(parent.getChildAt(index)))) { 113 | View sectionView = parent.getChildAt(index); 114 | int sectionTop = sectionView.getTop(); 115 | int pinViewHeight = pinnedHeaderView.getHeight(); 116 | if (sectionTop < pinViewHeight && sectionTop > 0) { 117 | sectionPinOffset = sectionTop - pinViewHeight; 118 | } 119 | } 120 | } 121 | int saveCount = c.save(); 122 | c.translate(0, sectionPinOffset); 123 | c.clipRect(0, 0, parent.getWidth(), pinnedHeaderView.getMeasuredHeight()); 124 | pinnedHeaderView.draw(c); 125 | c.restoreToCount(saveCount); 126 | } 127 | 128 | } 129 | } 130 | ``` 131 | 132 |        整个功能到这就结束了，是不是很简单 133 |
