Gradle

implementation 'com.yydcdut:markdown-processor:0.1.3'
implementation 'com.yydcdut:rxmarkdown-wrapper:0.1.3'

Or if you don't want to use RxJava, you can simply refer to markdown-processor :

implementation 'com.yydcdut:markdown-processor:0.1.3'

Support Syntax

RxMarkdown now provides 2 factories to parse markdown, TextFactory and EditFactory .

TextFactory : Supports most of the markdown syntax,but it will destroy the integrity of the content. So, it applies to render in TextView .

EditFactory : Supports some syntax,and it won't destroy the integrity of the content, the parsing speed is faster than TextFactory , So, it applies to real-time preview in EditText .

Code HighLight Theme

The lib supports some themes, ThemeDefault, ThemeDesert, ThemeSonsOfObsidian and ThemeSunburst.

ThemeDefaultThemeDesertThemeSonsOfObsidianThemeSunburst
ThemeDefaultThemeDesertThemeSonsOfObsidianThemeSunburst

You can implement the interface Theme to realize your own theme.

public class CodeHighLightTheme implements Theme {

    @Override
    public int getBackgroundColor() {//background color
        return 0xffcccccc;
    }

    @Override
    public int getTypeColor() {//color for type
        return 0xff660066;
    }

    @Override
    public int getKeyWordColor() {//color for keyword
        return 0xff000088;
    }

    @Override
    public int getLiteralColor() {//color for literal
        return 0xff006666;
    }

    @Override
    public int getCommentColor() {//color for comment
        return 0xff880000;
    }

    @Override
    public int getStringColor() {//color for string
        return 0xff008800;
    }

    @Override
    public int getPunctuationColor() {//color for punctuation
        return 0xff666600;

        return 0xff000000;
    }

    @Override
    public int getDecimalColor() {//color for a markup declaration such as a DOCTYPE
