youcan try:

public class TestGallery extends Activity {
/** Called when the activity is first created. */
private Integer[] mImageIds = { R.drawable.sample_1, R.drawable.sample_2, R.drawable.sample_3, R.drawable.sample_4 }; 

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Gallery g = (Gallery) findViewById(R.id.gallery); 
    g.setAdapter(new ImageAdapter(this)); 

    g.setOnItemClickListener(new OnItemClickListener() { 
        public void onItemClick(AdapterView parent, View v, int position, long id) { 
            if (position >= mImageIds.length) { 
                position = position % mImageIds.length; 
            } 
            Toast.makeText(TestGallery.this, "" + position, Toast.LENGTH_SHORT).show(); 
        } 
    }); 

}

public class ImageAdapter extends BaseAdapter { 
    int mGalleryItemBackground; 
    private Context mContext; 

    public ImageAdapter(Context c) { 
        mContext = c; 
        TypedArray a = obtainStyledAttributes(R.styleable.Gallery1); 
        mGalleryItemBackground = a.getResourceId(R.styleable.Gallery1_android_galleryItemBackground, 0); 

        a.recycle(); 
    } 

    public int getCount() { 
        return Integer.MAX_VALUE; 
    } 

    public Object getItem(int position) { 
        if (position >= mImageIds.length) { 
            position = position % mImageIds.length; 
        } 
        return position; 
    } 

    public long getItemId(int position) { 
        if (position >= mImageIds.length) { 
            position = position % mImageIds.length; 
        } 
        return position; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
        ImageView i = new ImageView(mContext); 
        if (position >= mImageIds.length) { 
            position = position % mImageIds.length; 
        } 
        i.setImageResource(mImageIds[position]); 
        i.setLayoutParams(new Gallery.LayoutParams(80, 80)); 
        i.setScaleType(ImageView.ScaleType.FIT_XY); 
        i.setBackgroundResource(mGalleryItemBackground); 
        return i; 
    } 

    public int checkPosition(int position) { 
        if (position >= mImageIds.length) { 
            position = position % mImageIds.length; 
        } 
        return position; 
    } 
}}
