61 | return imageView; 62 | } 63 | 64 | @Override 65 | public void updateUI(Context context, View view, int position, String data) { 66 | //在这里更新轮播图的UI 67 | //position 轮播图的第几个项 68 | //view 轮播图当前项的布局 它是createView方法的返回值 69 | //data 轮播图当前项对应的数据 70 | Glide.with(context).load(data).into((ImageView) view); 71 | } 72 | }, beans); 73 | ``` 74 | 轮播图的布局支持任何的布局，轮播图的数据类型也是支持任何的数据类型，这里只是用ImageView和String举例而已。 75 | #### 2）、其他方法的使用 76 | ```java 77 | //设置指示器类型，有普通指示器(ORDINARY)、数字指示器(NUMBER)和没有指示器(NONE)三种类型。 78 | //这个方法跟在布局中设置app:indicatorStyle是一样的 79 | mBanner.setIndicatorStyle(CustomBanner.IndicatorStyle.ORDINARY); 80 | 81 | //设置两个点图片作为翻页指示器，只有指示器为普通指示器(ORDINARY)时有用。 82 | //这个方法跟在布局中设置app:indicatorSelectRes、app:indicatorUnSelectRes是一样的。 83 | //第一个参数是指示器的选中的样式，第二个参数是指示器的未选中的样式。 84 | mBanner.setIndicatorRes(R.drawable.shape_point_select,R.drawable.shape_point_unselect)； 85 | mBanner.setIndicator(Drawable select, Drawable unSelect); 86 | 87 | //设置指示器的指示点间隔，只有指示器为普通指示器(ORDINARY)时有用。 88 | //这个方法跟在布局中设置app:indicatorInterval是一样的。 89 | mBanner.setIndicatorInterval(20) 90 | 91 | //设置指示器的方向。 92 | //这个方法跟在布局中设置app:indicatorGravity是一样的。 93 | mBanner.setIndicatorGravity(CustomBanner.IndicatorGravity.CENTER) 94 | 95 | //设置轮播图自动滚动轮播，参数是轮播图滚动的间隔时间 96 | //轮播图默认是不自动滚动的，如果不调用这个方法，轮播图将不会自动滚动。 97 | mBanner.startTurning(3600); 98 | 99 | //停止轮播图的自动滚动 100 | mBanner.stopTurning(); 101 | 102 | //设置轮播图的滚动速度 103 | mBanner.setScrollDuration(500); 104 | 105 | //设置轮播图的点击事件 106 | mBanner.setOnPageClickListener(new CustomBanner.OnPageClickListener() { 107 | @Override 108 | public void onPageClick(int position, String str) { 109 | //position 轮播图的第几个项 110 | //str 轮播图当前项对应的数据 111 | } 112 | }); 113 | ``` 114 | 以上是CustomBanner的主要常用方法，更多方法请查看源码。 115 | #### 3）、CustomBanner的很多方法都支持方法连缀，比如以下的方法可以这样调用。 116 | ```java 117 | mBanner.setPages(参数, 参数).setIndicatorRes(参数, 参数).setIndicatorGravity(参数).startTurning(参数); 118 | ``` 119 | ### 效果图 120 | ![](https://github.com/donkingliang/CustomBanner/blob/master/%E6%BC%94%E7%A4%BA.gif) 121 | 122 | 在我的博客中对该轮播图控件的实现和核心代码有详细的分析讲解，欢迎大家访问[我的博客](http://blog.csdn.net/u010177022) 123 | [Android轮播图控件的实现详解](http://blog.csdn.net/u010177022/article/details/61931488) 124 | -------------------------------------------------------------------------------- /app/src/main/java/com/donkingliang/bannerdemo/MainActivity.java: -------------------------------------------------------------------------------- 1 | package com.donkingliang.bannerdemo;
