使用步骤\r\n>以下提供的是最简单的步骤，需要复杂的样式自己可以自定义\r\n\r\n#### Step 1.依赖banner\r\nGradle \r\n```groovy\r\n\r\nrepositories {\r\n maven { url \"https://s01.oss.sonatype.org/content/groups/public\" }\r\n}\r\n\r\ndependencies{\r\n //2.1.0以前jcenter的依赖\r\n //implementation 'com.youth.banner:banner:2.1.0'\r\n //现在Maven Central\r\n implementation 'io.github.youth5201314:banner:2.2.3'\r\n\r\n}\r\n```\r\n\r\n#### Step 2.添加权限到你的 AndroidManifest.xml\r\n```xml\r\n\r\n \r\n\r\n```\r\n\r\n#### Step 3.在布局文件中添加Banner，可以设置自定义属性\r\n！！！此步骤可以省略，可以直接在Activity或者Fragment中new Banner();\r\n```xml\r\n\r\n```\r\n\r\n#### Step 4.继承BannerAdapter，和RecyclerView的Adapter一样（如果你只是图片轮播也可以使用默认的）\r\n！！！此步骤可以省略，图片轮播提供有默认适配器，其他的没有提供是因为大家的可变性要求不确定，所以直接自定义的比较好。\r\n```java\r\n\r\n/**\r\n * 自定义布局，下面是常见的图片样式，更多实现可以看demo，可以自己随意发挥\r\n */\r\npublic class ImageAdapter extends BannerAdapter {\r\n\r\n public ImageAdapter(List mDatas) {\r\n //设置数据，也可以调用banner提供的方法,或者自己在adapter中实现\r\n super(mDatas);\r\n }\r\n\r\n //创建ViewHolder，可以用viewType这个字段来区分不同的ViewHolder\r\n @Override\r\n public BannerViewHolder onCreateHolder(ViewGroup parent, int viewType) {\r\n ImageView imageView = new ImageView(parent.getContext());\r\n //注意，必须设置为match_parent，这个是viewpager2强制要求的\r\n imageView.setLayoutParams(new ViewGroup.LayoutParams(\r\n ViewGroup.LayoutParams.MATCH_PARENT,\r\n ViewGroup.LayoutParams.MATCH_PARENT));\r\n imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);\r\n return new BannerViewHolder(imageView);\r\n }\r\n\r\n @Override\r\n public void onBindView(BannerViewHolder holder, DataBean data, int position, int size) {\r\n holder.imageView.setImageResource(data.imageRes);\r\n }\r\n\r\n class BannerViewHolder extends RecyclerView.ViewHolder {\r\n ImageView imageView;\r\n\r\n public BannerViewHolder(@NonNull ImageView view) {\r\n super(view);\r\n this.imageView = view;\r\n }\r\n }\r\n}\r\n\r\n```\r\n\r\n#### Step 5.Banner具体方法调用 \r\n\r\n```java\r\npublic class BannerActivity extends AppCompatActivity {\r\n public void useBanner() {\r\n //--------------------------简单使用-------------------------------\r\n banner.addBannerLifecycleObserver(this)//添加生命周期观察者\r\n .setAdapter(new BannerExampleAdapter(DataBean.getTestData()))\r\n .setIndicator(new CircleIndicator(this));\r\n \r\n //—————————————————————————如果你想偷懒，而又只是图片轮播————————————————————————\r\n banner.setAdapter(new BannerImageAdapter(DataBean.getTestData3()) {\r\n @Override\r\n public void onBindView(BannerImageHolder holder, DataBean data, int position, int size) {\r\n //图片加载自己实现\r\n Glide.with(holder.itemView)\r\n .load(data.imageUrl)\r\n .apply(RequestOptions.bitmapTransform(new RoundedCorners(30)))\r\n .into(holder.imageView);\r\n }\r\n })\r\n .addBannerLifecycleObserver(this)//添加生命周期观察者\r\n .setIndicator(new CircleIndicator(this));\r\n //更多使用方法仔细阅读文档，或者查看demo\r\n }\r\n}\r\n```\r\n\r\n## Banner使用中优化体验\r\n**如果你需要考虑更好的体验，可以看看下面的代码**\r\n#### Step 1.（可选）生命周期改变时\r\n```java\r\npublic class BannerActivity {\r\n \r\n //方法一：自己控制banner的生命周期\r\n \r\n @Override\r\n protected void onStart() {\r\n super.onStart();\r\n //开始轮播\r\n banner.start();\r\n }\r\n \r\n @Override\r\n protected void onStop() {\r\n super.onStop();\r\n //停止轮播\r\n banner.stop();\r\n }\r\n \r\n @Override\r\n protected void onDestroy() {\r\n super.onDestroy();\r\n //销毁\r\n banner.destroy();\r\n }\r\n \r\n //方法二：调用banner的addBannerLifecycleObserver()方法，让banner自己控制\r\n \r\n protected void onCreate(Bundle savedInstanceState) {\r\n //添加生命周期观察者\r\n banner.addBannerLifecycleObserver(this);\r\n }\r\n}\r\n```\r\n\r\n\r\n## 常见问题（收录被反复询问的问题）\r\n\r\n* 网络图片加载不出来？\r\n\r\n `banner本身不提供图片加载功能，首先确认banner本身使用是否正确，具体参考demo，\r\n 然后请检查你的图片加载框架或者网络请求框架，服务端也可能加了https安全认证，是看下是否报有证书相关错误`\r\n \r\n* 怎么实现视频轮播？\r\n\r\n `demo中有实现类似淘宝商品详情的效果，第一个放视频，后面的放的是图片，并且可以设置首尾不能滑动。\r\n 因为大家使用的播放器不一样业务环境也不同，具体情况自己把握，demo就是给一个思路哈！可以参考和修改`\r\n\r\n* 我想指定轮播开始的位置？\r\n\r\n `现在提供了setStartPosition()方法，在sheAdapter和setDatas直接调用一次就行了，当然setAdapter后通过setCurrentItem设置也行`\r\n\r\n* 父控件滑动时，banner切换会获取焦点，然后自动全部显示。不想让banner获取焦点可以给父控件加上：\r\n\r\n ```\r\n //banner也一定要用最新版哦！\r\n android:focusable=\"true\"\r\n android:focusableInTouchMode=\"true\"\r\n ```\r\n* 怎么设置圆角？\r\n 1、调用提供的方法或者自定义属性进行设置，这里设置的是banner本身的圆角，不是轮播内view的圆角\r\n 2、在adapter中对自定义的view进行自己实现，就拿图片举例：可以自己定义一个圆角的ImageView控件，或者使用glide渲染都行。请举一反三，view都自定义了还有什么不能改的？\r\n \r\n \r\n## Thanks\r\n\r\n- [MZBannerView](https://github.com/pinguo-zhouwei/MZBannerView)\r\n-

banner 去掉泛型返回\n * demo 添加更新数据注释\n * 更新viewpager2到beta2\n\n#### v2.2.1-2.2.2\n * 对kotlin使用的兼容支持\n * 对kotlin使用demo进行了修改\n * 新版本都将迁移至MavenCentral\n * 更新viewpager2到1.1.0-alpha01\n * 修改bug\n \n#### v2.2.0\n * 自定义属性中增加可选择设置banner圆角的具体方向\n * 增加DrawableIndicator指示器,支持直接设置图片了，可以通过构造方法或者自定义属性设置\n * 合并ZakAnun朋友提交的优化监听器的设置以及减少 onPageScrolled 回调\n * 对demo进行了修改\n * 新的版本迁移将至jitpack仓库\n\n#### v2.1.0\n * 修改banner圆角锯齿\n * 修改画廊支持左右不同的大小\n * 内置增加了默认的图片适配器，方便偷懒的人，但是其他类型的没有内置是因为可变性太高了，大家自定义就好\n * 自定义参数全部修改成banner_开头了，避免和其他库冲突。麻烦使用的大家修改下！\n\n#### v2.0.12\n * 修改了new banner时无默认参数的问题\n * 自带的指示器支持选中和默认的宽度\n * setAdapter支持设置是否无限循环\n \n#### v2.0.11\n * 合并了lvshaojun朋友提交的代码\n \n#### v2.0.9\n * 增加了addBannerLifecycleObserver()方法，给banner添加生命周期观察者，将生命周期交给banner自己处理，\n 你也可以不使用这种方式自己象以前的方式自己控制，具体可以参考文档和demo\n * 修改了DepthPageTransformer效果，现在使用这种效果返回的位置应该没有问题了\n * 其他优化\n\n#### v2.0.8\n * 修复bug\n * 增加混淆配置\n\n#### v2.0.7\n * 修复画廊问题\n * 增加了多种PageTransformer\n * 增加滑动距离方法\n * demo中提供了adapter数据操作示例\n *

增加了view的添加和分离回调时，分别暂停和开始轮播，主要解决滑动嵌套时不可见轮播。这个也可以自己监听实现哈\n \n#### v2.0.3-2.0.4\n banner 修复了几个紧急bug，圆角绘制引起的残影和焦点问题，替换layoutmanager为null的异常\n \n#### v2.0.2\n banner bug修复\n * 有朋友想要在引导页使用banner，所以增加了is_infinite_loop属性来控制是否能无限循环\n * 增加了设置开始轮播位置的方法\n * 修复圆角裁剪和首次设置开始位置不对的bug\n * demo中增加了类似淘宝详情banner的案例，第一个放视频，不能无限循环\n * 设置指示器方法调整，demo增加自定义数字指示器案例\n * 对ProxyLayoutManger进行的优化\n\n#### v2.0.1\n banner bug修改\n * 解决一系列嵌套banner的事件冲突和解决方案\n （如果我没有考虑到的场景，大家再反馈或者提交方案）\n\n#### v2.0.0\n banner 正式版发布\n * 改变banner圆角实现方式，兼容低版本\n * 新增两种指示器效果，基本能满足大部分需求了\n\n#### v2.0.0-beta\n banner 测试版发布\n * 修改banner内部轮播逻辑\n * 增加设置画廊效果方法\n * 内置有2种官方Transformer效果，更多效果你可以自定义\n * 优化切换事件和点击事件,去掉onBannerChanged方法\n * 新增轮播滑动时间控制，感谢zguop，这里的具体实现方法来自zguop的项目\n * 支持多PageTransformer组合设置\n\n#### v2.0.0-alpha03\n banner 预览版使用中的问题优化。\n 这里要感谢BoldFruit朋友修复了一个bug；我爷爷得了癌症住院了需要照顾，公司事情也多，所以更新频率会慢很多。希望大家理解！\n 不过我更希望大家要是发现bug，亦可以自己修复提交，有什么想法新增的功能也可以提交过来。可以提供一个良好的开源环境哈！\n 还有不要一直夺命连环催，大家都有自己的事情，多多理解！\n \n * 增加支持布局文件中使用自定义指示器了（自己发挥）\n * 增加支持Android5.0以上的设置banner圆角方法\n * 其他问题修复（有些实在是不好复现加上有点忙，只修改了部分bug）\n\n#### v2.0.0-alpha02\n banner 预览版使用中的问题优化\n * #666 修改orientation自定义属性与其他库冲突问题：改成banner_orientation\n * 增加RecyclerView嵌套banner和ConstraintLayout中使用banner测试demo\n * #669 RecyclerView嵌套banner 轮播优化代码建议，demo中可以查看\n * 其他问题修复\n\n#### v2.0.0-alpha\n banner 2.0全新基础升级，目前是预览版，使用中的问题慢慢迭代\n * 使用了ViewPager2为基础控件 \n * 支持了androidx兼容包\n * 方便了UI、Indicator自定义（现在还是基础版本，后面再提升）\n * 依赖包目前只需要导入了ViewPager2\n" }, { "path": "usekotlin/.gitignore", "content": "/build\n" },
