万能imageLoader加载图片的包装，直接用

ImageLoader 是android一款牛逼的开源项目，为了大家能更方便的使用，我在这里分别对

1：加载网络图片

2：加载drwable目录图片

3：加载assert目录的图片

4：加载相册图片

等模块进行了封装：

import android.widget.ImageView;

import com.nostra13.universalimageloader.core.DisplayImageOptions;
import com.nostra13.universalimageloader.core.ImageLoader;
import com.nostra13.universalimageloader.core.assist.ImageLoadingListener;

/**
* @ClassName ImageLoaderUtils.java
* @Description universalimageloader
*              封装加载网络和本地的图片(相册,assert目录,drawable目录,不包括.9.png图片)
*              String imageUri= "http://site.com/image.png"; // from Web
*              String imageUri ="file:///mnt/sdcard/image.png"; // from SD card
*              String imageUri= "content://media/external/audio/albumart/13"; // from content provider
*              String imageUri = "assets://image.png"; // from assets
*              String imageUri = "drawable://" + R.drawable.image; // from drawables (only images, non-9patch)

加载相册图片: ImageLoaderUtils.displayImage(ImageLoaderUtils.FilePrefix.FILE, mPhotoPath, iv_head_img);

加载Asset目录图片: ImageLoaderUtils.displayImage(FilePrefix.ASSETS, "ic_pulish_channel.png", ivLoadingFlash,ishouApplication.loadingOptionsPublishChinal);

加载drawable图片:ImageLoaderUtils.displayImage(FilePrefix.DRAWABLE, ""+R.drawable.ic_launch, ivLoadingFlash,ishouApplication.loadingOptions);
