How can I build rich text editor in Android studio like Contenteditable in HTML/JS? I am interested at Text-Editing app, so I am trying to build my own in Android Studio using available native solutions, like contenteditable in HTML. What I want to get is: Having a full control over the text field, e.g ‘input’ event like in DOM APIs. The content is fully customizable. I don’t want to use library or any dependencies.
