gallery每屏仅显示一幅图片

 

   public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView = new ImageView(context);
        Bitmap bitmap = this.images.get(position);
        imageView.setImageBitmap(bitmap);
        //设置样式 ：填充整个屏幕
        imageView.setLayoutParams(new Gallery.LayoutParams(Gallery.LayoutParams.FILL_PARENT,
                Gallery.LayoutParams.FILL_PARENT));
        //设置缩放比例：保持原样
        imageView.setScaleType(ImageView.ScaleType.CENTER);
        return imageView;
    }
