## 使用步骤
>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
#### Step 1.依赖banner
Gradle
```groovy
repositories {
maven { url "https://s01.oss.sonatype.org/content/groups/public" }
}
dependencies{
//2.1.0以前jcenter的依赖
//implementation 'com.youth.banner:banner:2.1.0'
//现在Maven Central
implementation 'io.github.youth5201314:banner:2.2.3'
}
```
#### Step 2.添加权限到你的 AndroidManifest.xml
```xml
<!-- if you want to load images from the internet -->
<uses-permission android:name="android.permission.INTERNET" />
```
#### Step 3.在布局文件中添加Banner，可以设置自定义属性
！！！此步骤可以省略，可以直接在Activity或者Fragment中new Banner();
```xml
<com.youth.banner.Banner
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/banner"
android:layout_width="match_parent"
android:layout_height="高度自己设置" />
```
#### 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）
！！！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。
```java
/**
* 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
*/
public class ImageAdapter extends BannerAdapter<DataBean, ImageAdapter.BannerViewHolder> {
public ImageAdapter(List<DataBean> mDatas) {
//设置数据，也可以调用banner提供的方法,或者自己在adapter中实现
super(mDatas);
}
//创建ViewHolder，可以用viewType这个字段来区分不同的ViewHolder
@Override
public BannerViewHolder onCreateHolder(ViewGroup parent, int viewType) {
ImageView imageView = new ImageView(parent.getContext());
//注意，必须设置为match_parent，这个是viewpager2强制要求的
imageView.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
return new BannerViewHolder(imageView);
}
@Override
public void onBindView(BannerViewHolder holder, DataBean data, int position, int size) {
holder.imageView.setImageResource(data.imageRes);
}
class BannerViewHolder extends RecyclerView.ViewHolder {
ImageView imageView;
public BannerViewHolder(@NonNull ImageView view) {
super(view);
this.imageView = view;
}
}
}
```
#### Step 5.Banner具体方法调用
```java
public class BannerActivity extends AppCompatActivity {
public void useBanner() {
//--------------------------简单使用-------------------------------
banner.addBannerLifecycleObserver(this)//添加生命周期观察者
.setAdapter(new BannerExampleAdapter(DataBean.getTestData()))
.setIndicator(new CircleIndicator(this));
//—————————————————————————如果你想偷懒，而又只是图片轮播————————————————————————
banner.setAdapter(new BannerImageAdapter<DataBean>(DataBean.getTestData3()) {
@Override
public void onBindView(BannerImageHolder holder, DataBean data, int position, int size) {
//图片加载自己实现
Glide.with(holder.itemView)
.load(data.imageUrl)
.apply(RequestOptions.bitmapTransform(new RoundedCorners(30)))
.into(holder.imageView);
}
})
.addBannerLifecycleObserver(this)//添加生命周期观察者
.setIndicator(new CircleIndicator(this));
//更多使用方法仔细阅读文档，或者查看demo
}
}
```
## Banner使用中优化体验
**如果你需要考虑更好的体验，可以看看下面的代码**
#### Step 1.（可选）生命周期改变时
```java
public class BannerActivity {
//方法一：自己控制banner的生命周期
@Override
protected void onStart() {
super.onStart();
//开始轮播
banner.start();
}
@Override
protected void onStop() {
super.onStop();
//停止轮播
banner.stop();
}
@Override
protected void onDestroy() {
super.onDestroy();
//销毁
banner.destroy();
}
//方法二：调用banner的addBannerLifecycleObserver()方法，让banner自己控制
protected void onCreate(Bundle savedInstanceState) {
//添加生命周期观察者
banner.addBannerLifecycleObserver(this);
}
}
```
## 常见问题（收录被反复询问的问题）
* 网络图片加载不出来？
`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，
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`
* 怎么实现视频轮播？
`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。
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`
* 我想指定轮播开始的位置？
`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`
* 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：
```
//banner也一定要用最新版哦！
android:focusable="true"
android:focusableInTouchMode="true"
```
* 怎么设置圆角？
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
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？
