最开始是想上传以前基于viewpager更新好的版本，但是看着viewpager2正式版已经出来了，就上新的吧，viewpager2确实比viewpager性能好很多。 22 | 23 | - [x] 使用了ViewPager2为基础控件 ViewPager2介绍 24 | - [x] 支持了androidx兼容包 25 | - [x] 方便了UI、Indicator自定义 26 | - [x] 支持画廊效果、魅族效果 27 | - [x] 兼容了水平和垂直轮播，也可以实现类似淘宝头条的效果 28 | - [x] 依赖包目前只需要导入了ViewPager2 29 | 30 | 31 | 32 | ### 效果图 33 | 更多效果运行demo查看 34 | 35 | ![默认](images/banner_example.gif) 36 | 37 |

139 | 140 | #### Step 1.依赖banner 141 | Gradle 142 | ```groovy 143 | 144 | repositories { 145 | maven { url "https://s01.oss.sonatype.org/content/groups/public" } 146 | } 147 | 148 | dependencies{ 149 | //2.1.0以前jcenter的依赖 150 | //implementation 'com.youth.banner:banner:2.1.0' 151 | //现在Maven Central 152 | implementation 'io.github.youth5201314:banner:2.2.3' 153 | 154 | } 155 | ``` 156 | 157 | #### Step 2.添加权限到你的 AndroidManifest.xml 158 | ```xml 159 | 160 | 161 | 162 | ``` 163 | 164 | #### Step 3.在布局文件中添加Banner，可以设置自定义属性 165 | ！！！此步骤可以省略，可以直接在Activity或者Fragment中new Banner(); 166 | ```xml 167 | 172 | ``` 173 | 174 | #### 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） 175 | ！！！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。 176 | ```java 177 | 178 | /** 179 | * 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 180 | */ 181 | public class ImageAdapter extends BannerAdapter { 182 | 183 | public ImageAdapter(List mDatas) { 184 | //设置数据，也可以调用banner提供的方法,或者自己在adapter中实现 185 | super(mDatas); 186 | } 187 | 188 | //创建ViewHolder，可以用viewType这个字段来区分不同的ViewHolder 189 | @Override 190 | public BannerViewHolder onCreateHolder(ViewGroup parent, int viewType) { 191 | ImageView imageView = new ImageView(parent.getContext()); 192 | //注意，必须设置为match_parent，这个是viewpager2强制要求的 193 | imageView.setLayoutParams(new ViewGroup.LayoutParams( 194 | ViewGroup.LayoutParams.MATCH_PARENT, 195 | ViewGroup.LayoutParams.MATCH_PARENT)); 196 | imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 197 | return new BannerViewHolder(imageView); 198 | } 199 | 200 | @Override 201 | public void onBindView(BannerViewHolder holder, DataBean data, int position, int size) { 202 | holder.imageView.setImageResource(data.imageRes); 203 | } 204 | 205 | class BannerViewHolder extends RecyclerView.ViewHolder { 206 | ImageView imageView; 207 | 208 | public BannerViewHolder(@NonNull ImageView view) { 209 | super(view); 210 | this.imageView = view; 211 | } 212 | } 213 | } 214 | 215 | ``` 216 | 217 | #### Step 5.Banner具体方法调用 218 | 219 | ```java 220 | public class BannerActivity extends AppCompatActivity { 221 | public void useBanner() { 222 | //--------------------------简单使用------------------------------- 223 | banner.addBannerLifecycleObserver(this)//添加生命周期观察者 224 | .setAdapter(new BannerExampleAdapter(DataBean.getTestData())) 225 | .setIndicator(new CircleIndicator(this)); 226 | 227 | //—————————————————————————如果你想偷懒，而又只是图片轮播———————————————————————— 228 | banner.setAdapter(new BannerImageAdapter(DataBean.getTestData3()) { 229 | @Override 230 | public void onBindView(BannerImageHolder holder, DataBean data, int position, int size) { 231 | //图片加载自己实现 232 | Glide.with(holder.itemView) 233 | .load(data.imageUrl) 234 | .apply(RequestOptions.bitmapTransform(new RoundedCorners(30))) 235 | .into(holder.imageView); 236 | } 237 | }) 238 | .addBannerLifecycleObserver(this)//添加生命周期观察者 239 | .setIndicator(new CircleIndicator(this)); 240 | //更多使用方法仔细阅读文档，或者查看demo 241 | } 242 | } 243 | ``` 244 | 245 | ## Banner使用中优化体验 246 | **如果你需要考虑更好的体验，可以看看下面的代码** 247 | #### Step 1.（可选）生命周期改变时 248 | ```java 249 | public class BannerActivity { 250 | 251 | //方法一：自己控制banner的生命周期 252 | 253 | @Override 254 | protected void onStart() { 255 | super.onStart(); 256 | //开始轮播 257 | banner.start(); 258 | } 259 | 260 | @Override 261 | protected void onStop() { 262 | super.onStop(); 263 | //停止轮播 264 | banner.stop(); 265 | } 266 | 267 | @Override 268 | protected void onDestroy() { 269 | super.onDestroy(); 270 | //销毁 271 | banner.destroy(); 272 | } 273 | 274 | //方法二：调用banner的addBannerLifecycleObserver()方法，让banner自己控制 275 | 276 | protected void onCreate(Bundle savedInstanceState) { 277 | //添加生命周期观察者 278 | banner.addBannerLifecycleObserver(this); 279 | } 280 | } 281 | ``` 282 | 283 | 284 | ## 常见问题（收录被反复询问的问题） 285 | 286 | * 网络图片加载不出来？ 287 | 288 | `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， 289 | 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` 290 | 291 | * 怎么实现视频轮播？ 292 | 293 | `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。 294 | 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` 295 | 296 | * 我想指定轮播开始的位置？ 297 | 298 | `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` 299 | 300 | * 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： 301 | 302 | ``` 303 | //banner也一定要用最新版哦！ 304 | android:focusable="true" 305 | android:focusableInTouchMode="true" 306 | ``` 307 | * 怎么设置圆角？ 308 | 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 309 | 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？ 310 | 311 | 312 | ## Thanks 313 | 314 | -
