Answer 1

I have tried this one and found one way to solve this. Please try this also:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:gravity="center" xmlns:android="http://schemas.android.com/apk/res/android">
    <Gallery android:id="@+id/galleryid"
        android:layout_width="fill_parent" 
        android:layout_height="match_parent"/>      
</LinearLayout>

image_gallery_items.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"
    android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content" android:padding="3sp" android:orientation="vertical" android:gravity="center_horizontal"> 

    <ImageView android:id="@+id/image" android:src="@drawable/icon"
        android:layout_height="110dp" android:layout_width="130dp" android:layout_gravity="center"></ImageView>
    <TextView android:text="TextView" android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>

</LinearLayout>

GalleryExample.java

 public class GalleryExample extends Activity {
        private  Gallery galleryView;
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            galleryView = (Gallery)findViewById(R.id.galleryid);
            galleryView.setAdapter(new ImageAdapter(this));
        }
}

ImageAdapter.java

 public class ImageAdapter extends BaseAdapter {

        private Activity activity;
        private static LayoutInflater inflater=null;

        public ImageAdapter(Activity a) {
            activity = a;
            inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        }

        public int getCount() {
            return data.length;
        }

        public Object getItem(int position) {
            return position;
        }

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

        public static class ViewHolder{
            public TextView text;
            public ImageView image;
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            View vi=convertView;
            ViewHolder holder;
            if(convertView==null){
                vi = inflater.inflate(R.layout.image_gallery_items, null);
                holder=new ViewHolder();
                holder.text=(TextView)vi.findViewById(R.id.textView1);
                holder.image=(ImageView)vi.findViewById(R.id.image);
                vi.setTag(holder);
            }
            else
                holder=(ViewHolder)vi.getTag();
            holder.text.setText(name[position]);
            final int stub_id=data[position];
            holder.image.setImageResource(stub_id);
            return vi;
        }

        private int[] data = {
                R.drawable.imag1, R.drawable.imag2,
                R.drawable.imag3, R.drawable.imag4,
                R.drawable.imag5, R.drawable.imag6
        };
        private String[] name = {
                "Image1", "Image2",
                "Image3", "Image4",
                "Image5", "Image6"
        };
    }

And in the AndroidMAnifest.xml specify GalleryExample only.
