Code and examples for my talk "Composing Creatively with Custom Layouts".

Composing Creatively with Custom Layouts

This project contains example code from my Droidcon NYC talk. There are three launchers which can be independently launched to show working examples.

Note: this code is for presentation/example purposes so the more complex examples are not rigorously implemented but meant to show the relatively power of custom canvas and layout work.

Project Structure

This is a multi-module application project with:

1. An app module that contains the three example launches.
2. A build-logic module that contains convention plugins for various ecosystem and other Gradle plugins used. Convention plugin logic pulls heavily from https://github.com/android/nowinandroid but with several personal modifications.
3. Library code modules:

• imeji contains custom Compose canvas drawing example that has a faux image cropper
• custom-modifier contains a custom layout modifier by which custom logic can be reusably packaged as a modifier; this also helps to illustrate Compose Phases
• schedule contains a simple custom Compose layout example and contrasts using platform containers vs. customizing layout via a faux scheduling component

Launchers

To run the examples, create run configurations for the following activities:

1. app -> rt.compose.custom.ImejiActivity
2. app -> rt.compose.custom.PolarCoordinatesActivity
3. app -> rt.compose.custom.ScheduleActivity
