Wysiwyg component to use inside my Android app?

My Android app lets users write HTML fragme开发者_JAVA百科nts.

WYSIWYG would be nice, but is there a WYSIWYG widget available for the Android UI?

Or do you know a JavaScript-based WYSIWYG component that works in an Android WebView?

Preferably usable in an Open Source app. Ideally Open Source itself.

There's a very simple and native Wysiwyg editor in android.

You can find the source code in the Wordpress app for Android: https://android.trac.wordpress.org/browser/trunk/src/org/wordpress/android/editPost.java#L634
