![Stickheaderlayout](https://raw.githubusercontent.com/yang747046912/Stickheaderlayout/master/image/pp.gif) 23 | ##原理 24 | Stickheaderlayout 继承 ViewGroup ，总体分为三块 25 | - 头部 26 | 可以放置上下不可滚动的view 27 | - 标题 28 | 可以放置上下不可滚动的view（不想出现标题则可以仅放一条横线） 29 | - 内容 30 | 可以放置GridView、ListView、RecyclerView、ScrollView、ViewPager并且兼容下拉刷新跟上拉自动加载更多 31 | 32 | 使用ViewDragHelper跟View事件的拦截相关的东西，ViewDragHelper不了解的可访问http://www.jianshu.com/p/bfe857e509c9 33 | 34 | ##IpmlScrollChangListener 介绍 35 | 包含四个方法 36 | - boolean isReadyForPull() 37 | 是否可以将head拉下来 38 | - void onStartScroll() 39 | 滚动开始 40 | - void onStopScroll() 41 | 滚动开始 42 | - void onScrollChange(int dy, int totallDy) 43 | 滚动距离的变化 dy:滚动的距离 totallDy:可滚动的最大距离 配合 setRetentionHeight(int )可以用于做渐变的titlebar （见viewPagerDemo效果图） 44 | 45 | ##StickHeaderLayout 方法介绍 46 | - setRetentionHeight(int retentionHeight) 47 | 设置向上滚动headView 保留的高度 48 | - setScroll(IpmlScrollChangListener scroll) 49 | 设置滚动回调 50 | 51 | ##ViewDragHelper初始化 52 | - 滚动状态监听 53 | ``` 54 | public void onViewDragStateChanged(int state) { 55 | super.onViewDragStateChanged(state); 56 | if (scroll != null) { 57 | if (state == ViewDragHelper.STATE_IDLE) { 58 | scroll.onStopScroll(); 59 | } 60 | if (state == ViewDragHelper.STATE_SETTLING) { 61 | scroll.onStartScroll(); 62 | } 63 | } 64 | } 65 | ``` 66 | - 判断ViewDragHelper是否触发滚动 头部、标题、内容都可以滑动 67 | ``` 68 | public boolean tryCaptureView(View child, int pointerId) { 69 | return true; 70 | } 71 | ``` 72 | - 手指按住contentView时滚动时，头部、标题、内容的位置变化,返回contentView是移动距离 73 | ``` 74 | public int clampViewPositionVertical(View child, int top, int dy) { 75 | if (child == headView) { 76 | int headViewTop = headView.getTop() + dy; 77 | if (headViewTop > 0) { 78 | headViewTop = 0; 79 | } else if (headViewTop < -headHeight + retentionHeight) { 80 | headViewTop = -headHeight + retentionHeight; 81 | } 82 | return headViewTop; 83 | } 84 | if (child == titleView) { 85 | int titleTop = titleView.getTop() + dy; 86 | if (titleTop > headHeight) { 87 | titleTop = headHeight; 88 | } else if (titleTop < retentionHeight) { 89 | titleTop = retentionHeight; 90 | } 91 | return titleTop; 92 | } 93 | int contentTop = contentView.getTop() + dy; 94 | if (contentTop > headHeight + titleHeight) { 95 | contentTop = headHeight + titleHeight; 96 | } else if (contentTop < titleHeight + retentionHeight) { 97 | contentTop = titleHeight + retentionHeight; 98 | } 99 | return contentTop; 100 | } 101 | ``` 102 | - 手指离开屏幕时，触发快速滚动 103 | ``` 104 | public void onViewReleased(View releasedChild, float xvel, float yvel) { 105 | super.onViewReleased(releasedChild, xvel, yvel); 106 | if (dragEdge == DragEdge.Bottom) { 107 | if (yvel < -mDragHelper.getMinVelocity()) { 108 | mDragHelper.smoothSlideViewTo(contentView, 0, titleHeight + retentionHeight); 109 | } else if (releasedChild == headView) { 110 | mDragHelper.smoothSlideViewTo(headView, 0, -headHeight + retentionHeight); 111 | } else { 112 | mDragHelper.smoothSlideViewTo(titleView, 0, retentionHeight); 113 | } 114 | } else if (dragEdge == DragEdge.Top) { 115 | if (releasedChild == contentView) { 116 | mDragHelper.smoothSlideViewTo(contentView, 0, titleHeight + headHeight); 117 | } else if (releasedChild == headView) { 118 | mDragHelper.smoothSlideViewTo(headView, 0, 0); 119 | } else { 120 | mDragHelper.smoothSlideViewTo(titleView, 0, headHeight); 121 | } 122 | } 123 | invalidate(); 124 | } 125 | ``` 126 | - 触发快速滚动后头部、标题、内容的位置变化 127 | ``` 128 | public void onViewPositionChanged(View changedView, int left, int top, int dx, int dy) { 129 | super.onViewPositionChanged(changedView, left, top, dx, dy); 130 |
