Top Android ScrollView Libraries

Top Android ScrollView Libraries.

ScrollView is a fundamental UI component in Android that allows users to scroll through content that is larger than the screen size. While the default ScrollView provided by the Android SDK is functional, there are several third-party libraries available that add additional features and customization options.

In this tutorial, we will explore some of the top Android ScrollView libraries and learn how to install them in your project. We will also provide code examples to demonstrate their usage.

Let's get started!

1. Android-ObservableScrollView​

Android-ObservableScrollView is a library that provides a flexible ScrollView with various useful features. It allows you to easily create immersive scrolling effects, such as parallax scrolling or sticky headers, in your Android apps.

Installation​

To install Android-ObservableScrollView, add the following dependency to your app's build.gradle file:

implementation 'com.github.ksoichiro:android-observablescrollview:1.6.0'

Usage​

First, include the ObservableScrollView in your layout XML file:

<com.github.ksoichiro.android.observablescrollview.ObservableScrollView
    android:id="@+id/scroll_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <!-- Your content here -->
    
</com.github.ksoichiro.android.observablescrollview.ObservableScrollView>

Next, in your Java or Kotlin code, you can use the ObservableScrollView to achieve various scrolling effects. For example, to implement a parallax effect, you can use the ScrollUtils class provided by the library:

val scrollView = findViewById<ObservableScrollView>(R.id.scroll_view)
val imageView = findViewById<ImageView>(R.id.image_view)

val parallaxListener = object : ObservableScrollView.OnScrollChangedListener {
    override fun onScrollChanged(scrollY: Int, firstScroll: Boolean, dragging: Boolean) {
        val newScrollY = ScrollUtils.getFloat(scrollY, 0, 500)
        imageView.translationY = newScrollY * 0.5f
    }
}

scrollView.addScrollViewCallbacks(parallaxListener)

For more details on the available features and customization options, refer to the official documentation.

2. KenBurnsView​

KenBurnsView is a ScrollView library that adds a beautiful Ken Burns effect to your images during scrolling. It provides a smooth animation that zooms and pans the images, creating an engaging visual experience.

Installation​

To install KenBurnsView, add the following dependency to your app's build.gradle file:

implementation 'com.flaviofaria:kenburnsview:1.0.7'

Usage​

In your layout XML file, replace the default ScrollView with the KenBurnsView:

<com.flaviofaria.kenburnsview.KenBurnsView
    android:id="@+id/ken_burns_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <!-- Your content here -->
    
</com.flaviofaria.kenburnsview.KenBurnsView>

To start the Ken Burns animation, simply call the startKenBurnsAnimation() method on the KenBurnsView:

val kenBurnsView = findViewById<KenBurnsView>(R.id.ken_burns_view)
kenBurnsView.startKenBurnsAnimation()

For more advanced customization options, refer to the official documentation.

Additional Libraries​

Here are some additional Android ScrollView libraries that you might find useful:

  • DiscreteScrollView: A scrollable list of items with discrete scrolling.
  • FlexibleScrollView: A flexible ScrollView that supports pull-to-refresh and overscroll effects.
  • NestedScrollView: An official AndroidX library that provides a ScrollView with nested scrolling capabilities.
  • AKParallax-Android - AKParallax-Android is a Library Project that provides a parallax effect to an imageView in a ScrollView or a ListView..
  • AndroidPullMenu - An Android Library that allows users to pull down a menu and select different actions. It can be implemented inside ScrollView, GridView, ListView..
  • StickyScrollViewItems - A small android library for tagging views inside a ScrollView as "sticky" making them stick to the top of the scroll container until a new sticky view comes and takes it's place.
  • scrollviewlibrary - Android library to manage scroll view by horizontally or vertically..
  • ScalableScrollView - This library is modification of android.widget.ScrollView and allows user to resize TextView, placed into it, by two fingers..
  • FadingToolbar - FadingToolbar is an animation library which fades out your header view in a ScrollView/RecyclerView and fades in a toolbar (top app bar) title (analogue of the LargeTitle animation in iOS).

Feel free to explore these libraries and choose the one that best fits your needs.

That's it! You now have an overview of some of the top Android ScrollView libraries, along with installation instructions and code examples for their usage. Happy scrolling!
