NativeHtml

Renders HTML to native Android components. Easily extensible with custom native elements.

The main use case for this library is rendering HTML-formatted text or (custom) components in cases where TextView HTML capabilities are too limited and WebView is too heavyweight or not suitable for other reasons.

Use Cases

• Formatted help pages with links directly into the application
• Rendering server-provided content with custom native elements
• Multiple components with HTML content in a single view where multiple WebView instances would be prohibitive in terms of resource consumption

Limitations

• CSS is mostly limited to CSS 2
• Floating elements are not supported
• Formatted text is rendering using built-in TextViews with spans, which means that justified text is not supported.

Extensibility

• To implement custom elements, extend AndroidPlatform and override createElement. Native Android views can be wrapped in AndroidWrapperElement
• Platform-independent and platform-specific parts of the code base are clearly separated, so it should be straightforward to port the code to any platform that supports Java and provides a component for formatted text.
• Layout managers are separated from containers. So while flexbox is currently not supported, it should be relatively straightforward to implement in a way similar to the existing BlockLayout and TableLayout classes.

Usage

For a simple example, please refer to the demo

Gradle

Jitpack for the win!

Step 1: Add jitpack to your root build.gradle at the end of repositories:

allprojects {
        repositories {
          ...
          maven { url 'https://jitpack.io' }
        }
    }

Step 2: Add the HtmlView2 dependency

dependencies {
    compile 'com.github.stefanhaustein.nativehtml:android:v1.0.6'
}
