1 Text Styling
2 ============
3 These samples shows how to style text on Android using spans, in [Java](https://github.com/googlesamples/android-text/tree/master/TextStyling-Java) and in [Kotlin](https://github.com/googlesamples/android-text/tree/master/TextStyling-Kotlin).

6 Introduction
7 ------------
8 The difference between [TextStyling-Java](https://github.com/googlesamples/android-text/tree/master/TextStyling-Java) and [TextStyling-Kotlin](https://github.com/googlesamples/android-text/tree/master/TextStyling-Kotlin) is only in the language. They have the same set of features, same class names and similar ways of testing the functionality.
9 ## Features
10 Parse some hardcoded text and do the following:
11 * Paragraphs starting with > are transformed into quotes.
12 * Text enclosed in ``` will be transformed into inline code block.
13 * Lines starting with + or * will be transformed into bullet points.
14 To update the text, modify the value of `R.string.display_text`.
15 This project is not meant to fully cover the markdown capabilities and has several limitations; for example, quotes do not support nesting other elements.
16
17 ## Implementation
18 The text is parsed in the `Parser.parse` method and the spans are created in the `MarkdownBuilder.markdownToSpans` method.
19 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`.
20
21 ## Testing
22 Text parsing is tested with JUnit tests in `ParserTest`. Span building is tested via Android JUnit tests, in `MarkdownBuilderTest`.
