public View getView(int position, View convertView, ViewGroup parent) {
  Log.d(TAG, "convertView = " + convertView + " position = " + position);
  ImageView imageview = new ImageView(mContext);
  //给ImageView设置资源

  imageview.setImageResource(mImageIds[position % mImageIds.length]); //循环显示
  imageview.setScaleType(ImageView.ScaleType.FIT_CENTER);

  if(selectItem==position){
   //Animation animation = AnimationUtils.loadAnimation(mContext, R.anim.hyperspace_out);


   //ScaleAnimation animation = new ScaleAnimation(0, 2, 0, 2,
   //  ScaleAnimation.RELATIVE_TO_SELF, 0, ScaleAnimation.RELATIVE_TO_SELF, 0);
   //animation.setDuration(2000);
   //imageview.startAnimation(animation);
   imageview.setLayoutParams(new Gallery.LayoutParams(150,150));
  }
  else{

imageview.setLayoutParams(new Gallery.LayoutParams(120,120));
}

  return imageview;
}

public void setSelectItem(int selectItem) {

  if (this.selectItem != selectItem) {
   this.selectItem = selectItem;
   notifyDataSetChanged();
  }
}
