You solve your problem in Fragment Add method in adapter

 public Bitmap decodeImage(int gridViewImageId) {
    try {
        // Decode image size
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeResource(mContext.getResources(), gridViewImageId, o);
        // The new size we want to scale to
        final int REQUIRED_SIZE = 100; // you are free to modify size as your requirement

        // Find the correct scale value. It should be the power of 2.
        int scale = 1;
        while (o.outWidth / scale / 2 >= REQUIRED_SIZE && o.outHeight / scale / 2 >= REQUIRED_SIZE)
            scale *= 2;

        // Decode with inSampleSize
        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeResource(mContext.getResources(), gridViewImageId, o2);
    } catch (Throwable e) {
        e.printStackTrace();
    }
    return null;

}

and add this line

imageViewAndroid.setImageBitmap(decodeImage(gridViewImageId[i]));
