Transitioner provides easy, dynamic and adjustable animations between two views with nested children.

App design featurehere.

First you need to create a Transitioner object containing your original and ending views:

val transition=Transitioner(original_view, ending_view)

The view pairs must have matching "tag" attributes so that they can be bound together:

<ConstraintLayoutandroid:id="@+id/original_view"android:tag="constrView"        ...>        <TextViewandroid:id="@+id/text"android:tag="firstView"            .../></ConstraintLayout><ConstraintLayoutandroid:id="@+id/ending_view"android:tag="constrView"android:visibility="invisible"        ...>        <EditTextandroid:id="@+id/text3"android:tag="firstView"            .../> </ConstraintLayout>

I recommend you hide the second view layout, since it's only used as a placeholder for the end destination.The views can be of any type, you can mix and match them, the two layouts can have a different number of views and nested layouts are 100% supported. The only things to keep in mind are:

• all views which you would want to match together must have the same tag attribute in both layouts

• all unmatched views will remain at their original place inside the original layout

• the second layout is just a placeholder. It doesn't hold any logic, it only shows where the original layout should move to.

 transition.setProgress(0.5f)//or transition.setProgress(50)

transition.duration=500transition.interpolator=AccelerateDecelerateInterpolator()transition.animateTo(percent=0f)transition.onProgressChanged {//triggered on every progress change of the transition    seekBar.progress= (it*100).toInt()    }val progress:Float= transition.currentProgress

Here is a preview of a simple application made using this library

This effect can be reproduced by placing the "Transitioner.setProgress(Float)" function inside a onTouch or a onProgressChanged method.

The recommended way to download is to copythe single library class file and use it in your application.
