Step 1.依赖banner

Gradle

dependencies{

compile 'com.youth.banner:banner:2.1.0'

}

Step 2.添加权限到你的 AndroidManifest.xml

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();

有时候banner不显示  是因为height要设置一个固定值

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" />

1.简单的图片展示

public class IMGBean {

public IMGBean(int imageRes) {

this.imageRes = imageRes;

}

public int imageRes;

public int getImageRes() {

return imageRes;

}

public void setImageRes(int imageRes) {

this.imageRes = imageRes;

}

public static List getData() {

List list = new ArrayList<>();

list.add(new IMGBean(R.mipmap.fta_ad1));

list.add(new IMGBean(R.mipmap.fta_ad2));

return list;

}

}

private void initBanner() {

mBanner.setAdapter(new BannerImageAdapter(IMGBean.getData()) {

@Override

public void onBindView(BannerImageHolder holder, IMGBean data, int position, int size) {

//图片加载自己实现

RoundedCorners roundedCorners = new RoundedCorners(10);

RequestOptions options = RequestOptions.bitmapTransform(roundedCorners);

Glide.with(holder.itemView).load(data.imageRes).apply(options).into(holder.imageView);

}

})

.addBannerLifecycleObserver(this)//添加生命周期观察者

.setIndicator(new CircleIndicator(getActivity()));

//更多使用方法仔细阅读文档，或者查看demo

}

2.网络获取的List 数据结合使用  我这里用MMM.BBB代替JavaBean对象

~~1.定义Adapter

public class MyBannerAdapter extends BannerAdapter {

public MyBannerAdapter(List datas) {

super(datas);

}

@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

ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(

ViewGroup.LayoutParams.MATCH_PARENT,

ViewGroup.LayoutParams.MATCH_PARENT);

imageView.setLayoutParams(params);

imageView.setScaleType(ImageView.ScaleType.FIT_XY);

return new BannerViewHolder(imageView);

}

@Override

public void onBindView(BannerViewHolder holder, MMM.BBB data, int position, int size) {

RoundedCorners roundedCorners = new RoundedCorners(10);

RequestOptions options = RequestOptions.bitmapTransform(roundedCorners);

Glide.with(holder.itemView).load(data.getOguyEkaJ()).apply(options).into(holder.imageView);

// holder.imageView.setImageResource(data.getOguyEkaJ());

//设置点击事件

holder.imageView.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

Log.e("tttttttt",data.getXODHXxeB()+"");

}

});

}

class BannerViewHolder extends RecyclerView.ViewHolder {

ImageView imageView;

public BannerViewHolder(@NonNull ImageView view) {

super(view);

this.imageView = view;

}

}

}

2.设置

mBanner.setAdapter(new MyBannerAdapter(data))

.addBannerLifecycleObserver(this)//添加生命周期观察者

.setIndicator(new CircleIndicator(getActivity()));
