Glide - 一个专注于平滑滚动的 Android 图像加载和缓存库

Glide is a fast and efficient open source media management framework for Android that wraps media decoding, memory and disk caching, and resource pooling into a simple and easy to use interface.

Glide supports fetching, decoding, and displaying video stills, images, and animated GIFs. Glide includes a flexible api that allows developers to plug in to almost any network stack. By default Glide uses a custom HttpUrlConnection based stack, but also includes utility libraries plug in to Google's Volley project or Square's OkHttp library instead.

Glide's primary focus is on making scrolling any kind of a list of images as smooth and fast as possible, but Glide is also effective for almost any case where you need to fetch, resize, and display a remote image.

Download

You can download a jar from GitHub'sreleases page.

Or use Gradle:

repositories {   mavenCentral() }  dependencies {     compile 'com.github.bumptech.glide:glide:3.5.0'     compile 'com.android.support:support-v4:19.1.0' }

Or Maven:

<dependency>   <groupId>com.github.bumptech.glide</groupId>   <artifactId>glide</artifactId>   <version>3.5.0</version>   <type>aar</type> </dependency> <dependency>   <groupId>com.google.android</groupId>   <artifactId>support-v4</artifactId>   <version>r7</version> </dependency>

How do I use Glide?

Checkout theGitHub wiki for pages on a variety of topics, and see the javadocs .

Simple use cases will look something like this:

// For a simple view: @Override public void onCreate(Bundle savedInstanceState) {  ...  ImageView imageView = (ImageView) findViewById(R.id.my_image_view);  Glide.with(this).load("http://goo.gl/h8qOq7").into(imageView); } // For a list: @Override public View getView(int position, View recycled, ViewGroup container) {  final ImageView myImageView;  if (recycled == null) {   myImageView = (ImageView) inflater.inflate(R.layout.my_image_view,     container, false);  } else {   myImageView = (ImageView) recycled;  }  String url = myUrls.get(position);  Glide.with(myFragment)   .load(url)   .centerCrop()   .placeholder(R.drawable.loading_spinner)   .crossFade()   .into(myImageView);  return myImageView; } 

OkHttp and Volley

Support for OkHttp and Volley is provided by integration libraries you can optionally include as dependencies. The integration libraries are available via Maven or thereleases page.

For instructions on including either the OkHttp or the Volley integration libraries, see the Integration Libraries wiki page.

Android SDK Version

Glide requires a minimum sdk version of 10.

License

BSD, part MIT and Apache 2.0. See LICENSE file for details.

Version 3 is a stable public release used in multiple open source projects at Google including in the Android Camera app and in the 2014 Google IO app. Comments/bugs/questions/pull requests welcome!

Building Glide with gradle is fairly straight forward:

git clone git@github.com:bumptech/glide.git cd glide git submodule init && git submodule update ./gradlew jar 

Note: Make sure your Android SDK has the Android Support Repository installed, and that your $ANDROID_HOME environment variable is pointing at the SDK or add a local.properties file in the root project with a sdk.dir=... line.

Samples

Follow the steps in the 'Build' section to setup the project and then:

./gradlew :samples:flickr:run ./gradlew :samples:giphy:run ./gradlew :samples:svg:run 

Development

Follow the steps in the 'Build' section to setup the project and then edit the files however you wish. Intellij IDEA 14 cleanly imports both Glide's source and tests and is the recommended way to work with Glide.

To open the project in Intellij 14:

1. Go to File.
2. Click on 'Open...'
3. Navigate to Glide's root directory.
4. Select glide-parent.iml
