AndroidSlidingUpPanel
AndroidSlidingUpPanel is an Android custom view component and sliding panel library used to create draggable overlays that slide up from the bottom of an application screen. It functions as a nested scrolling UI framework that coordinates touch events between a draggable panel and its internal scrollable content.
The library distinguishes itself through a parallax effect implementation that shifts background content at different speeds than the foreground panel. It supports the definition of intermediate anchor points to create partial-view states and allows for transition physics customization to produce bounce or overshoot effects during movement.
The component manages view-layering through content overlay or push modes and supports custom drag handles to restrict sliding triggers. It further handles nested scrolling management to ensure internal content scrolls only after the panel reaches full expansion.
Features
- Android UI Components - Provides a reusable Android UI component for creating draggable bottom-sliding panels.
- Custom View Rendering - Implements a custom view that overrides standard measurement and drawing for sliding panel transitions.
- Nested Scroll Coordination - Coordinates touch events to ensure internal content scrolls only after the sliding panel is fully expanded.
- Nested Scroll Event Frameworks - Functions as a framework for coordinating touch events between a draggable panel and its internal scrollable content.
- Android Nested Scrolling - Manages scrollable views inside the panel so that content scrolls only after full panel expansion.
- Slide-Out Panels - Provides a specialized sliding panel component for creating draggable overlays from the bottom of the screen.
- Nested Scroll Management - Integrates scrollable views so that content scrolls only after the panel reaches full expansion.
- Coordinate-to-Translation Mapping - Calculates real-time view offsets by mapping raw touch coordinates to vertical translation values.
- Android Layout Components - Implements custom drag handles and anchor points to control the interaction between the sliding panel and other Android views.
- Physics-Based Property Interpolators - Uses physics-based property interpolators to create fluid panel movement and overshoot effects.
- View Hierarchy Composition - Manages the z-axis relationship and view hierarchy between the sliding panel and the main content.
- Partial-View State Anchors - Establishes fixed midpoints where the panel stops during expansion to provide a partial-view state.
- Floating Overlays - Provides a floating overlay mode that allows the panel to slide over the main layout.
- Mobile Interaction Patterns - Implements custom physics and parallax effects to improve the tactile feel of the mobile interface.
- Parallax Effects - Provides a mechanism to shift main content at a different speed than the sliding panel to create depth.
- Parallax Backgrounds - Implements a parallax effect that shifts background content at a fractional rate relative to the panel movement.
- Transition Physics - Implements scroll interpolators to provide customizable bounce and overshoot physics during panel movement.
- Snap Points - Provides magnetic snap points that allow the sliding panel to lock at specific vertical coordinates during movement.
- Navigation Components - Draggable sliding panel implementation.
- Sliding Components - Adds a draggable sliding panel to layouts.
- UI Components - Draggable sliding panel for bottom-up UI interactions.
