How can images be added to a listview?

The images in the ListView can be added using an Adapter. The specific steps are as follows:

1. Create a custom Adapter that extends either BaseAdapter or ArrayAdapter, depending on your needs.
2. In the getView method of Adapter, load the layout of the list item using LayoutInflater and find the ImageView control using findViewById.
3. Set an image for an ImageView using methods like setImageResource, setImageBitmap, or setImageDrawable.

The example code is provided below:

public class MyAdapter extends BaseAdapter {
    private Context mContext;
    private List<Integer> mImageList;

    public MyAdapter(Context context, List<Integer> imageList) {
        mContext = context;
        mImageList = imageList;
    }

    @Override
    public int getCount() {
        return mImageList.size();
    }

    @Override
    public Object getItem(int position) {
        return mImageList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.list_item_layout, parent, false);
        ImageView imageView = view.findViewById(R.id.image_view);
        imageView.setImageResource(mImageList.get(position));
        return view;
    }
}

Next, in the Activity or Fragment, create a ListView and set the Adapter.

ListView listView = findViewById(R.id.list_view);
List<Integer> imageList = new ArrayList<>();
imageList.add(R.drawable.image1);
imageList.add(R.drawable.image2);
imageList.add(R.drawable.image3);
MyAdapter adapter = new MyAdapter(this, imageList);
listView.setAdapter(adapter);

The code example above assumes that a list_item_layout layout file has already been defined, which includes an ImageView control with the id of image_view.

Note: In actual use, feel free to make appropriate modifications and optimizations based on your own needs.
