演示 13 | ![image](https://github.com/jeasonlzy0216/PullZoomView/blob/master/screenshots/demo1.png)![image](https://github.com/jeasonlzy0216/PullZoomView/blob/master/screenshots/demo2.png)![image](https://github.com/jeasonlzy0216/PullZoomView/blob/master/screenshots/demo3.png)![image](https://github.com/jeasonlzy0216/PullZoomView/blob/master/screenshots/demo4.gif)![image](https://github.com/jeasonlzy0216/PullZoomView/blob/master/screenshots/demo5.gif)![image](https://github.com/jeasonlzy0216/PullZoomView/blob/master/screenshots/demo6.gif) 14 | 15 | ## 1.温馨提示 16 | 该项目和我github上其他的view相关的项目已经一起打包上传到jCenter仓库中（源码地址 [https://github.com/jeasonlzy0216/ViewCore](https://github.com/jeasonlzy0216/ViewCore) ），使用的时候可以直接使用compile依赖，用法如下 17 | ```java 18 | compile 'com.lzy.widget:view-core:0.2.2' 19 | ``` 20 | 或者使用 21 | ```java 22 | compile project(':pullzoom') 23 | ``` 24 | 25 | 26 | ## 2.实现原理 27 | PullZoomView 继承至 ScrollView，通过布局设置 Tag 和 重写滑动事件，达到 PullZoomView 与 其他子View嵌套使用，同时增加了外部监听器。 28 | 29 | ## 3.自定义属性 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 |
自定义属性名字参数含义
pzv_sensitive图片放大效果相对于手指滑动距离的敏感度，越小越敏感，默认值 1.5
pzv_isZoomEnable是否允许下拉时头部放大效果，默认 true，即为允许
pzv_isParallax滑动时，是否头部具有视差动画，默认 true， 即为有
pzv_zoomTime松手时，缩放头部还原到原始大小的时间，单位毫秒，默认 500毫秒
56 | 57 | ## 4.使用注意事项 58 | * `PullZoomView` 使用时，需要三个Tag同时设置才能正常工作，否者会抛出异常，即在xml布局中对应的View中，加入如下tag，详细请参看Demo。 59 | ```java 60 | android:tag="header" 61 | android:tag="zoom" 62 | android:tag="content" 63 | ``` 64 | * 与ListView嵌套使用时，ListView需要使用本库中提供的 `ExpandListView` 65 | * 与GridView嵌套使用时，GridView需要使用本库中提供的 `ExpandGridView` 66 | * 与RecyclerView嵌套使用时，RecyclerView使用v7包中原生的即可，但是LayoutManager需要使用本库中提供的三个管理者，分别是 `ExpandLinearLayoutManager`, `ExpandGridLayoutManager`, `ExpandStaggeredGridLayoutManager` 67 | * 其他例如 ScrollView，WebView，View子类，ViewGroup子类均使用原生类即可，不用做任何改动。 68 | 69 | ## 5.代码参考 70 | 对外提供了滑动监听器`PullZoomView.OnScrollListener`，其中有三个方法 71 | 72 | * `onScroll(int l, int t, int oldl, int oldt)`: 表示`PullZoomView`滑动全程的监听 73 | * `onHeaderScroll(int currentY, int maxY)`: 表示头部从完全展现，到完全滑出的监听过程 74 | * `onContentScroll(int l, int t, int oldl, int oldt)`： 表示除了头部外，内容布局从最顶部滑动到最底部的监听过程 75 | 76 | 同时提供了下拉放大的监听器`PullZoomView.OnPullZoomListener`,其中有两个方法 77 | * `onPullZoom(int originHeight, int currentHeight)`:表示下拉头部时,头部的的当前大小,单位px 78 | * `onZoomFinish()`:表示头部恢复原始大小,即放大结束后的回调 79 | 80 | 此外允许通过代码对滑动行为动态控制 81 | ```java 82 | pzv.setIsParallax(true); //允许视差动画 83 | pzv.setIsZoomEnable(true); //允许头部放大 84 | pzv.setSensitive(1.5f); //敏感度1.5 85 | pzv.setZoomTime(500); //头部缩放时间500毫秒 86 | ``` 87 | 以上四个方法不是必须设置的，根据需要，可以使用自定义属性设置，也可以使用以上代码动态设置。 88 | 89 | 完整代码参考如下： 90 | ```java 91 | PullZoomView pzv = (PullZoomView) findViewById(R.id.pzv); 92 | pzv.setIsParallax(true); //允许视差动画 93 | pzv.setIsZoomEnable(true); //允许头部放大 94 | pzv.setSensitive(1.5f); //敏感度1.5 95 | pzv.setZoomTime(500); //头部缩放时间500毫秒 96 | pzv.setOnScrollListener(new PullZoomView.OnScrollListener() { 97 | @Override 98 | public void onScroll(int l, int t, int oldl, int oldt) { 99 | System.out.println("onScroll t:" + t + " oldt:" + oldt); 100 | } 101 | 102 | @Override 103 | public void onHeaderScroll(int currentY, int maxY) { 104 | System.out.println("onHeaderScroll currentY:" + currentY + " maxY:" + maxY); 105 | } 106 | 107 | @Override 108 | public void onContentScroll(int l, int t, int oldl, int oldt) { 109 | System.out.println("onContentScroll t:" + t + " oldt:" + oldt); 110 | } 111 | }); 112 | pzv.setOnPullZoomListener(new PullZoomView.OnPullZoomListener() { 113 | @Override 114 | public void onPullZoom(int originHeight, int currentHeight) { 115 | System.out.println("onPullZoom originHeight:" + originHeight + " currentHeight:" + currentHeight); 116 | } 117 | 118 | @Override 119 | public void onZoomFinish() { 120 | System.out.println("onZoomFinish"); 121 | } 122 | }); 123 | ``` 124 | -------------------------------------------------------------------------------- /app/.gitignore:
