Android PickerView
Android-PickerView is a custom view library for Android that provides a wheel-based scrolling interface for selecting dates, times, and custom data options. It functions as a selection component that can be used for specialized time and date picking or as a general wheel picker for custom data sets.
The library features cascading selection capabilities, allowing for linked data selectors where choosing an option in one column filters the available choices in subsequent columns. It also supports cyclic scrolling to create a continuous loop and can encapsulate the selector within a modal dialog overlay.
The component supports visual customization of layouts and text elements, along with dynamic range restrictions to limit selectable indices. It manages multi-column hierarchical options and provides interaction settings for the selector container.
