android中的ImageGallery和ImageGrid

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


    g.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView parent, View v, int position, long id) {

    ImageView imageView = new ImageView(PhotoGallery.this);
    imageView.setLayoutParams(new GridView.LayoutParams(45, 45));
    imageView.setAdjustViewBounds(false);
    imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
    imageView.setPadding(8, 8, 8, 8);
    imageView.setImageResource(mImageIds[position]);

    mGrid.addView(imageView);
   }

我用上面的代码在网格视图中添加了图像,这是有效的代码吗?我的意思是这个代码会产生内存不足的错误吗
