Achieve ViewPager-Like Horizontal Scroll with "DiscreteScrollView"

Introduction:

"DiscreteScrollView" is an open-source GitHub project designed for implementing a horizontal scroll list in Android applications similar to ViewPager. However, each item is displayed at the center of the screen and allows for swift scrolling. It is implemented using RecyclerView and is exceptionally simple to use.

Key Features:

  • Supports smooth scrolling.
  • Enables fast scrolling.
  • Offers various animation effects.
  • Supports custom scroll behavior.

How to Use:

Integrating "DiscreteScrollView" into your Android application is straightforward. Simply add the following dependency:

dependencies {
    implementation 'com.yarolegovich:discrete-scrollview:1.5.1'
}

Here's an example code snippet:

// Create a DiscreteScrollView
val scrollView = DiscreteScrollView(requireContext())

// Set the data source
val items = listOf("Item 1", "Item 2", "Item 3")
scrollView.adapter = DiscreteScrollViewAdapter(items) { item ->
    // Handle click events
    Toast.makeText(requireContext(), item, Toast.LENGTH_SHORT).show()
}

// Display the DiscreteScrollView
scrollView.show()

After running this example, you'll see a DiscreteScrollView containing three items. You can swipe left or right to view each item.

"DiscreteScrollView" also supports custom scroll behavior. You can set the scroll animation effect by modifying the snapHelper property.

Here are some example code snippets:

// Set the scroll animation effect to be elastic
scrollView.snapHelper = PagerSnapHelper()

// Set the scroll animation effect to fade in and out
scrollView.snapHelper = LinearSnapHelper()

Conclusion:

"DiscreteScrollView" is an exceptionally user-friendly horizontal scroll list library that allows you to quickly achieve ViewPager-like effects in your Android application.
