About Me wasabeef @wasabeef_jp
About Fresco • Image Manager • Streaming • Animations •
Drawing • Loading
Quick Start
Adding Fresco to your Project dependencies { // your app's
other dependencies compile 'com.facebook.fresco:fresco:0.2.0+' }
Adding Fresco to your Project public class MainApplication extends Application
{ ! @Override public void onCreate() { super.onCreate(); Fresco.initialize(this); } }
Adding Fresco to your Project <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> !
<com.facebook.drawee.view.SimpleDraweeView android:id="@+id/image" android:layout_width="300dp" android:layout_height="300dp"/> ! </RelativeLayout>
Adding Fresco to your Project public class MainActivity extends ActionBarActivity
{ ! @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ! SimpleDraweeView drawee = (SimpleDraweeView) findViewById(R.id.image); ! Uri uri = Uri.parse(“http://bit.ly/1PDoTv2"); drawee.setImageURI(uri); } }
Supported URIs 5ZQF 4DIFNF 'FUDINFUIPEVTFE 'JMFPOOFUXPSL http://, https:// HttpURLConnection or
network layer 'JMFPOEFWJDF pMF 'JMF*OQVU4USFBN $POUFOUQSPWJEFS DPOUFOU $POUFOU3FTPMWFS "TTFUJOBQQ BTTFU "TTFU.BOBHFS 3FTPVSDFJOBQQ SFT 3FTPVSDFTPQFO3BX3FTPVSDF
Concepts • DraweeView • DraweeHierarchy • DraweeController • The Image
Pipeline
Drawee Guide
Using Drawees in XML <com.facebook.drawee.view.SimpleDraweeView android:id="@+id/my_image_view" android:layout_width="20dp" android:layout_height="20dp" fresco:fadeDuration="300" fresco:actualImageScaleType="focusCrop"
fresco:placeholderImage="@color/wait_color" fresco:placeholderImageScaleType="fitCenter" fresco:failureImage="@drawable/error" fresco:failureImageScaleType="centerInside" fresco:retryImage="@drawable/retrying" fresco:retryImageScaleType="centerCrop" fresco:progressBarImage="@drawable/progress_bar" fresco:progressBarImageScaleType="centerInside" fresco:progressBarAutoRotateInterval="1000" fresco:backgroundImage="@color/blue" fresco:overlayImage="@drawable/watermark" fresco:pressedStateOverlayImage="@color/red" fresco:roundAsCircle="false" fresco:roundedCornerRadius="1dp" fresco:roundTopLeft="true" fresco:roundTopRight="false" fresco:roundBottomLeft="false" fresco:roundBottomRight="true" fresco:roundWithOverlayColor="@color/corner_color" fresco:roundingBorderWidth="2dp" fresco:roundingBorderColor=“@color/border_color"/>
Animated Images • Fresco supports animated GIF and WebP images.
• Control of animation
Resizing and Rotating public class ResizeOptions { public final int
width; public final int height; ! public ResizeOptions(int width, int height) { /** **/ } }
Listening to Download Events public interface ControllerListener<INFO> { void onSubmit(String
var1, Object var2); ! void onFinalImageSet(String var1, INFO var2, Animatable var3); ! void onIntermediateImageSet(String var1, INFO var2); ! void onIntermediateImageFailed(String var1, Throwable var2); ! void onFailure(String var1, Throwable var2); ! void onRelease(String var1); }
Modifying the Image public interface Postprocessor { void process(Bitmap var1);
! String getName(); } public interface Postprocessor { ! void process(Bitmap var1); ! String getName(); }
Image Pipeline Guide
Modifying the Image public interface Postprocessor { void process(Bitmap var1);
! String getName(); }
Configuring the Image Pipeline • Progressive JPEGs • Configuring the
disk cache • Keeping cache stats
Third Party Libraries
Using Other Network Layers public interface Postprocessor { void process(Bitmap
var1); ! String getName(); } dependencies { // your app's other dependencies compile ‘com.facebook.fresco:fresco:0.2.0+’ compile ‘com.facebook.fresco:imagepipeline-okhttp:0.2.0+' }
Using Other Image Loaders public interface Postprocessor { void process(Bitmap
var1); ! String getName(); } dependencies { // your app's other dependencies compile ‘com.facebook.fresco:fresco:0.2.0+’ compile ‘com.facebook.fresco:drawee-volley:0.2.0+' }
Thanks.
