UI Controls

Regardless of the Editor implementation that you are using, you might want to display UI controls to the user, in order to control the editor behavior. Similar to what happens with other VideoKit SDKs, we offer a default UI implementation called

With fragments

If you are using EditorFragment, a EditorControls view will be automatically added to the hierarchy and it is managed by the fragment itself, so there's nothing you should do.

When creating the fragment, you also have the option to pass a more generic layout resource that contains your overlays. If the view contains a EditorControls instance anywhere in the hierarchy, the recorder will find it and set it up.

val options = {
overlay(R.layout.editor_overlays) // customize overlays
overlay(null) // disable default controls

By default, the overlay() layout contains a single EditorControls view. Your overlays can contain a richer hierarchy or you can leverage a layout file to customize controls with the XML attributes listed below. You can also pass null to disable the default controls.

With other Editor implementations

When using other Editor implementations, the controls can be added to your view hierarchy as an overlay to the editor. For example, in case of EditorView, you can simply using a frame layout:

<!-- Part of your UI... -->

<!-- Add EditorView here: -->

<!-- Then add controls: -->


At runtime, the controls should be bound to the recorder using EditorControls.setEditor(). Once this is done, the controls class will start listening to the editor events and update the interface accordingly.

val editorView: EditorView = findViewById(
val editorControls: EditorControls = findViewById(

Customizing controls

The EditorControls class offers many APIs to control the controls appearance, both through XML attributes and programmatically.
