以下是一个示例代码，展示如何为多个ViewPager创建一个ImageAdapter：

首先，创建一个名为ImageAdapter的自定义适配器类：

public class ImageAdapter extends PagerAdapter {
    private Context mContext;
    private int[] mImages;

    public ImageAdapter(Context context, int[] images) {
        mContext = context;
        mImages = images;
    }

    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        ImageView imageView = new ImageView(mContext);
        imageView.setImageResource(mImages[position]);
        container.addView(imageView);
        return imageView;
    }

    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
        container.removeView((ImageView) object);
    }

    @Override
    public int getCount() {
        return mImages.length;
    }

    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object object) {
        return view == object;
    }
}

然后，在你的Activity或Fragment中，创建两个ViewPager，并为每个ViewPager设置一个ImageAdapter：

public class MainActivity extends AppCompatActivity {
    private ViewPager mViewPager1, mViewPager2;
    private ImageAdapter mAdapter1, mAdapter2;

    private int[] mImages1 = {R.drawable.image1, R.drawable.image2, R.drawable.image3};
    private int[] mImages2 = {R.drawable.image4, R.drawable.image5, R.drawable.image6};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mViewPager1 = findViewById(R.id.viewPager1);
        mViewPager2 = findViewById(R.id.viewPager2);

        mAdapter1 = new ImageAdapter(this, mImages1);
        mAdapter2 = new ImageAdapter(this, mImages2);

        mViewPager1.setAdapter(mAdapter1);
        mViewPager2.setAdapter(mAdapter2);
    }
}

最后，在你的布局文件中添加两个ViewPager：

这样，你就可以在一个Activity或Fragment中为两个ViewPager创建两个不同的适配器了。
