Android菜鸟学习笔记（ImageLoader加载图片）

ImageLoader imageLoader = ImageLoader.getInstance();
imageLoader.init(ImageLoaderConfiguration.createDefault(getActivity()));

//3,参数配置

DisplayImageOptions displayImageOptions = new DisplayImageOptions.Builder()

.showStubImage(R.drawable.ic_launcher)

.showImageOnFail(R.drawable.ic_launcher)

.imageScaleType(ImageScaleType.EXACTLY)

.showImageForEmptyUri(R.drawable.ic_launcher)

.cacheInMemory(true)

.cacheOnDisc(true).displayer(new FadeInBitmapDisplayer(300))

.imageScaleType(ImageScaleType.EXACTLY).build();

String URI = mImageUrl;

//4，设置图片。

ImageLoader.displayImage(URI, mImageView, new SimpleImageLoadingListener() {});

其中URI从网上查到不同路劲的地址书写情况

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)
