Answer 1

In the adapter you can see the method: getView, you can see this method returns an ImageView, so now you want the getView method to return an imageview and textview…

U can do this in a few ways, here how you can do it with a LayoutInflater

View v = getLayoutInflater().inflate(R.layout.gallery_item, null);
((ImageView) v.findViewById(R.id.img)).setImageResource(imageIds[position]);
((TextView) v.findViewById(R.id.caption)).setText(captions[position]);

So in your res/layout folder you should have an ‘gallery_item’ layout that contains an ImageView (img) and a TextView (caption)

i.e.

gallery_item.xml

 <LinearLayout>
      <ImageView ... />
      <TextView ... />
 </LinearLayout>

Hope this was helpfull!

EDIT

so as the above example shows you would need two arrays, one of imageIds and one of textCaptions. To keep your Adapter nice and clean it’s screaming for you to make an object.

 public class GalleryItem {
       int imageId;
       String caption

       // Constructor

       // getters and setters

 }

You could then pass an Array or List of your GalleryItems to the Adapter (replacing the setAdapter method). i.e:

 GalleryItem[] items = new GalleryItem[];

Then in your getView method as outlined above you would extract each object:

 GalleryItem item = items[position];
 View v = getLayoutInflater().inflate(R.layout.gallery_item, null);

((ImageView) v.findViewById(R.id.img)).setImageResource(item.getImageId());
((TextView) v.findViewById(R.id.caption)).setText(item.getCaption());

Hope thats clear
