Android component Glide to achieve smooth scrolling effect of picture _android

Glide is an Android based image loading and image caching component that can read, decode, and display pictures and videos on Android devices with maximum performance. Glide can be remote pictures, video, animation pictures, such as slow presence of equipment local, easy to improve the user to browse the image of the fluent experience.

The core function of glide is to improve the performance of the scrolling picture list, and glide can also meet the performance requirements for reading, resizing, and displaying remote images.

How to use Glide

The simplest example code is as follows:

For a simple view:
@Override the 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 Imagev Iew 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;
}

Application of volley communication framework on glide

Volley is an optional glide that can support Http/https to read pictures.

With Gradle:

dependencies {
  compile ' com.github.bumptech.glide:volley-integration:1.0.+ '
  compile ' Com.mcxiaoke.volley: library:1.0.+ '
}

or use Maven:

<dependency>
  <groupId>com.github.bumptech.glide</groupId>
  <artifactId> volley-integration</artifactid>
  <version>1.0.1</version>
  <type>jar</type >
</dependency>
<dependency>
  <groupId>com.mcxiaoke.volley</groupId>
  <artifactId>library</artifactId>
  <version>1.0.5</version>
  <type> Aar</type>
</dependency>

Then register the volley add-in in the activity or application:

public void OnCreate () {
 glide.get (this). Register (Glideurl.class, Inputstream.class,
    new Volleyurlloader.factory (Yourrequestqueue));
 ...
}

So all the requests will be passed through the volley.

Application of okhttp communication framework in Glide

In addition to volley,glide you can use the Okhttp communication framework, Okhttp also supports Http/https to read pictures.

With Gradle:

dependencies {
  compile ' com.github.bumptech.glide:okhttp-integration:1.0.+ '
  compile ' com.squareup.okhttp : okhttp:2.0.+ '
}

or use Maven:

<dependency>
  <groupId>com.github.bumptech.glide</groupId>
  <artifactId> okhttp-integration</artifactid>
  <version>1.0.1</version>
  <type>jar</type >
</dependency>
<dependency>
  <groupId>com.squareup.okhttp</groupId>
  <artifactId>okhttp</artifactId>
  <version>2.0.0</version>
  <type> Jar</type>
</dependency>

Then register the Okhttp add-in in the activity or application:

public void OnCreate () {
 glide.get (this). Register (Glideurl.class, Inputstream.class,
    new Okhttpurlloader.factory (yourokhttpclient));
 ...
}

Summarize

If your Android application involves remote image processing, the glide component can help you optimize your application in image video.
