Text Styling

These samples shows how to style text on Android using spans, in Java and in Kotlin.

Introduction

The difference between TextStyling-Java and TextStyling-Kotlin is only in the language. They have the same set of features, same class names and similar ways of testing the functionality.

Features

Parse some hardcoded text and do the following:

• Paragraphs starting with ?> ? are transformed into quotes.
• Text enclosed in ?```? will be transformed into inline code block.
• Lines starting with ?+ ? or ?* ? will be transformed into bullet points. To update the text, modify the value of R.string.display_text. This project is not meant to fully cover the markdown capabilities and has several limitations; for example, quotes do not support nesting other elements.

Implementation

The text is parsed in the Parser.parse method and the spans are created in the MarkdownBuilder.markdownToSpans method. To see how to apply a span, check out MarkdownBuilder.buildCodeBlockSpan. To see how to apply multiple spans on the same string, see MarkdownBuilder.buildQuoteSpan. For examples of creating custom spans, see BulletPointSpan, CodeBlockSpan or FontSpan.

Testing

Text parsing is tested with JUnit tests in ParserTest. Span building is tested via Android JUnit tests, in MarkdownBuilderTest.

Getting Started

Clone this repository, enter the top level directory and run ./gradlew tasks to get an overview of all the tasks available for this project.

Some important tasks are:

mbleDebug - Assembles all Debug builds.
allDebug - Installs the Debug build.
ectedAndroidTest - Installs and runs the tests for Debug build on connected
ces.
 - Run all unit tests.
