MaterialTheme colors in HtmlText

To use colors like MaterialTheme.colors.primary in HtmlText, map simple colors.

HtmlText(
    textId = R.string.hello_world,
    colorMapping = mapOf(Color.Red to MaterialTheme.colors.primary)
)
<resources>
    <string name="hello_world">"Hello <span style="color: red">World</span>"</string>
</resources>

String arguments in HtmlText

To use string arguments with HtmlText, use CDATA

HtmlText(
    text = stringResource(R.string.hello_world, "Hello")
)
<resources>
    <string name="hello_world"><![CDATA[%1$s World]]></string>
</resources>

Combine MaterialTheme colors and string arguments in HtmlText

You can combine colorMapping with string arguments (CDATA) and all other HTML tags. If you use CDATA, you have to escape double quotes.

<resources>
    <string name="hello_world"><![CDATA[Hello <span style=\"color: red\">World</span>]]></string>
</resources>

Add to your project

Add actual HtmlText library:

dependencies {
    implementation 'de.charlex.compose.material:material-html-text:2.0.0-beta01'
}

or

dependencies {
    implementation 'de.charlex.compose.material3:material3-html-text:2.0.0-beta01'
}

How does it work?

Use it like a normal Text composable

HtmlText(textId = R.string.hello_world)
<resources>
    <string name="hello_world">Hello <b>World</b>. This <i><strike>text</strike>sentence</i> is form<b>att<u>ed</u></b> in simple html. <a href="https://github.com/ch4rl3x/HtmlText">HtmlText</a></string>
</resources>
