fresco-parallax-drawee-view

It is hard to use parallax effect in your app when you are using fresco image loader library.

But if you use this library, you can use parallax effect while using fresco.


Parallax Sample1 Parallax Sample2

Include your project

add build.gradle

allprojects {
 repositories {
  ...
  maven { url "https://jitpack.io" }
 }
}
dependencies {
    compile 'com.github.bigstark:fresco-parallax-drawee-view:1.2.1'
}

Concept

  • It supports only vertical parallax effect.
  • It cannot support image crop.
  • Actual Image's ratio must be larger than DraweeView ratio.
  • Scroll offset is between 0 and 1 float value.

Usage

<com.bigstark.fresco.parallax.library.ParallaxDraweeView
    xmlns:fresco="http://schemas.android.com/apk/res-auto"
    android:id="@+id/pdv_sample"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    fresco:viewAspectRatio="1"
    fresco:fadeDuration="300"
    fresco:actualImageScaleType="fitCenter"
    />
ParallaxDraweeView pdvSample = (ParallaxDraweeView) findViewById(R.id.pdv_sample);
pdvSample.setImageURI(IMAGE_URI);

float offset = 0.5f;
pdvSample.setOffset(offset); // It could be run after image loaded.
