Easily Implement Shared Transition on Images

You can easily implement shared element transition on images using this library known as Transitional ImageView.

Let’s show you how to.

Step 1 – Install the Library

First register jitpack as a repository in your app level build.gradle:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Then install the library:

implementation 'com.github.mostafaaryan:transitional-imageview:v0.2.2'
}

Step 2

Create Transitional ImageView in your layout by pasting the following code:

<com.mostafaaryan.transitionalimageview.TransitionalImageView
        android:id="@+id/transitional_image"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:scaleType="fitXY"
        android:adjustViewBounds="true"
        app:res_id="@drawable/sample_image" />

Step 3

Now build a TransitionImageObject and set it to the TransitionalImageView:

TransitionalImageView transitionalImageView = (TransitionalImageView) findViewById(R.id.transitional_image);
TransitionalImage transitionalImage = new TransitionalImage.Builder()
                                    .duration(500)
                                    .backgroundColor(ContextCompat.getColor(MainActivity.this, R.color.color))
                                    .image(R.drawable.sample_image)
                                    /* or */
                                    .image(bitmap)
                                    .create();
transitionalImageView.setTransitionalImage(transitionalImage);

Full Example

Here is a beautiful example for using this library.

(a). Shoe.java

The model class to define a single shoe.

public class Shoe {

    private String Title;
    private String imageUrl;

    public Shoe(String title, String imageUrl) {
        Title = title;
        this.imageUrl = imageUrl;
    }

    public String getTitle() {
        return Title;
    }

    public String getImageUrl() {
        return imageUrl;
    }

}

(b). ShoeAdapter.java

Then the recyclerview adapter.

import android.support.v4.content.ContextCompat;

Java Shared Transition with Fragments and FloatingActionButton

This is a simple one-class example to utilize a shared element transition within fragments in an android activity. The programming language is Java. While it is not written in androidx, you can easily update it to androidx fragments and it doesn’t utilize any third partt library.

shared

Transitions

These are written in XML.  Tyically you create a transition resource directory and place the XML.

(a). shared_enter_transition.xml

Here is the code:

<?xml version="1.0" encoding="utf-8"?>
<transitionSet xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@integer/default_anim_duration">

    <changeTransform/>
    <arcMotion
        android:minimumHorizontalAngle="0"
        android:minimumVerticalAngle="15"
        android:maximumAngle="90" />
    <changeBounds />

</transitionSet>
