1.android-gif-drawable 的介绍

Views and Drawable for displaying animated GIFs on Android
官方地址

2.1 配置

Setup
Gradle (Android Studio)
Insert the following dependency to build.gradle
file of your project.

dependencies { 
        compile 'pl.droidsonroids.gif:android-gif-drawable:1.1.17'
}

Note that Maven central repository should be defined eg. in top-level build.gradle
like this:

buildscript { 
      repositories { 
              mavenCentral() 
      }
}

allprojects { 
      repositories { 
              mavenCentral() 
      }
}

2. 配置和简单实例

2.1 XML模式

直接将View部分的代码嵌入Layout文件中，添加Gif源，便可以正常工作：

<pl.droidsonroids.gif.GifImageView 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:src="@drawable/src_anim" 
       android:background="@drawable/bg_anim" 
/>

2.2 代码模式

• 编写XML：

<pl.droidsonroids.gif.GifImageButton    
android:id="@+id/gifImageButton"    
android:layout_width="match_parent"    
android:layout_height="match_parent"   
 />

• code:

  gifImageButton =(GifImageButton) findViewById(R.id.gifImageButton);
  gifImageButton.setImageResource(R.drawable.gif1);
  final MediaController mc = new MediaController(this);
  mc.setMediaPlayer( ( GifDrawable ) gifImageButton.getDrawable() );
  mc.setAnchorView( gifImageButton );
  gifImageButton.setOnClickListener( new View.OnClickListener(){    
        @Override    
        public void onClick ( View v )    {        
              mc.show();    
        }  
  }
 );

当然方法不是只有这一种，官方还有更多的方法，有时间再慢慢添加

GifImageView, GifImageButton and GifTextView
have also hooks for setters implemented. So animated GIFs can be set by calling setImageResource(int resId)
and setBackgroundResource(int resId)
GifDrawable
can be constructed directly from various sources:

动画的控制接口：

Animation control
![Uploading GIF-demo_024092.gif . . .]
GifDrawable
implements an Animatable
and MediaPlayerControl
so you can use its methods and more:
stop()

• stops the animation, can be called from any thread
  start()
• starts the animation, can be called from any thread
  isRunning()
• returns whether animation is currently running or not
  reset()
• rewinds the animation, does not restart stopped one
  setSpeed(float factor)
• sets new animation speed factor, eg. passing 2.0f will double the animation speed
  seekTo(int position)
• seeks animation (within current loop) to given position
  (in milliseconds)
  getDuration()
• returns duration of one loop of the animation
  getCurrentPosition()
• returns elapsed time from the beginning of a current loop of animation
