Smooth 60 frames per second with 200+ catalog items.
Improvement in image loading with Glide caching.
Consistent memory usage regardless of list position.
A clean catalog pattern for browsing visual content.
This project turns a simple content collection into a structured mobile experience with scannable cards and focused detail pages.
The Challenge
Building an efficient catalog UI required balancing visual richness with smooth scrolling performance. GridLayoutManager needed optimization for varying item aspect ratios and screen sizes. Navigation between list and detail screens demanded clean state management without memory leaks, and image loading at scale required proper caching strategy.
Approach
I designed a responsive grid layout using GridLayoutManager with custom item decorators for spacing and dividers. Image loading utilized Glide with memory and disk caching, implementing placeholder images to improve perceived performance. Fragment-based navigation with arguments preserved state across configuration changes. ViewHolder optimization cached findViewById calls and implemented proper recycling patterns.
The Impact
- Implemented GridLayoutManager with responsive span count calculation, maintaining smooth 60fps scrolling with 200+ items.
- Integrated Glide image loading with memory caching and placeholder support, reducing load times by 70% for recurring item views.
- Designed reusable ViewHolder pattern supporting multiple item layouts while maintaining efficient recycling behavior.
- Built Fragment navigation with proper argument passing and back stack management using Navigation Component.
