You can customizes the grid view with your own adapter class derived from BaseAdapter. Please use the following code:
Adapter Class:
public class ImageAdapter extends BaseAdapter { private Context mContext;
public Drawable[] images;
public ImageAdapter(Context c,Drawable[] d){
mContext = c;
images=d;
}
public int getCount() {
return images.length;
}
public Object getItem(int position) {
return images[position];
}
public long getItemId(int position) {
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(mContext);
imageView.setImageDrawable(images[position]);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setLayoutParams(new GridView.LayoutParams(70, 70));
return imageView;
}
}
Assign this adapter to your grid view as gridView.setAdapter(new ImageAdapter(GridImages.this,images));

I need to add the images to the grid view from a folder in my sd card. How can it be acheived?? Please help me out..

Please load the images from sdcard using Bitmap Factory as follows Bitmap gridImage = BitmapFactory.decodeFile(new File(Environment.getExternalStorageDirectory(), "file_name"); and please change the adapter constructor parameter Drawable[] to Bitmap[].
You might use also the TableLayout and set android:layout_width="match_parent" and android:layout_height="match_parent"to image to fill the cell and after manage your cells and rows as you want.
