代码：

1、adapter：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@drawable/button_bg"android:gravity="center"android:orientation="vertical"android:padding="20dp"><ImageViewandroid:id="@+id/ivImg"android:layout_width="match_parent"android:layout_height="300dp"android:scaleType="centerCrop" /><TextViewandroid:id="@+id/tvName"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_horizontal"android:layout_marginTop="10dp"android:textSize="24dp"android:textStyle="bold" /></LinearLayout>

public class VpAdapter extends PagerAdapter {private Context mContext;private List<VpModel> mList;public VpAdapter(Context context, List<VpModel> list) {this.mContext = context;this.mList = list;}@Overridepublic int getCount() {return mList == null ? 0 : mList.size();}@Overridepublic boolean isViewFromObject(@NonNull View view, @NonNull Object object) {return view == object;}@Overridepublic void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {container.removeView((View) object);}@NonNull@Overridepublic Object instantiateItem(@NonNull ViewGroup container, int position) {View itemView = LayoutInflater.from(mContext).inflate(R.layout.item_vp, container, false);ImageView img = itemView.findViewById(R.id.ivImg);TextView name = itemView.findViewById(R.id.tvName);Glide.with(mContext).load(mList.get(position).getUrl()).into(img);name.setText(mList.get(position).getName());container.addView(itemView);return itemView;}
}

2、UI

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:clipChildren="false"android:orientation="vertical"><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_horizontal"android:layout_marginTop="50dp"android:text="VP Test"android:textSize="30dp" /><androidx.viewpager.widget.ViewPagerandroid:id="@+id/vp"android:layout_width="match_parent"android:layout_height="400dp"android:layout_marginLeft="30dp"android:layout_marginTop="20dp"android:layout_marginRight="30dp"android:clipChildren="false" /></LinearLayout>

public class VpActivity extends ComponentActivity {@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.vp_activity);List<VpModel> list = new ArrayList<>();list.add(new VpModel("https://st-gdx.dancf.com/gaodingx/1942/articles/0/20201117-160009-ff34.png","哦莫"));list.add(new VpModel("https://pic0.sucaisucai.com/11/50/11050520_2.jpg","伸手让世界闭嘴"));list.add(new VpModel("https://cdn.pixabay.com/photo/2015/03/18/11/02/sunset-679122_1280.jpg","街边的服务站"));ViewPager viewPager = findViewById(R.id.vp);viewPager.setOffscreenPageLimit(list.size());viewPager.setPageMargin(30);viewPager.setAdapter(new VpAdapter(this, list));}
}

3、数据类

public class VpModel {private String url;private String name;public VpModel(String url, String name) {this.url = url;this.name = name;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}public String getName() {return name;}public void setName(String name) {this.name = name;}
}
