How to use SketchEditor Freehand v100.1

FrancisGagne

I tried to use the new SketchEditor. There's not much info on it beside the API doc, so here's my code:

if (viewerModel.getMapView().getSketchEditor() == null) {

SketchEditor sketch = new SketchEditor();
viewerModel.getMapView().setSketchEditor(sketch);
sketch.start(SketchCreationMode.FREEHAND_LINE);

} else {
viewerModel.getMapView().getSketchEditor().stop();
viewerModel.getMapView().setSketchEditor(null);
}

When I start the freehand sketch, the map pan with my movement so the line created is barely moving. I tried to overide the map onTouchListener onScroll , but it seems the SketchEditor is already doing that. There's probably another step I need to make I guess?

Can you help?

If I override the onTouch listener with nothing, the map won't do much...

The problem is, when I draw freehand on the map, the paning should be desactivated.

The SketchEditor.start() overwrites the touch listeners since it needs to know where the user draw. The problem in the SDK is probably just because super.onScroll() is called in the overriding.

I was referring to the onTouch, not the onScroll. When you override that, do you see the behavior you wish?

FrancisGagne

Yes, I already tried that.

mapView.setOnTouchListener(new DefaultMapViewOnTouchListener(viewerModel.getContext(), mapView) {
@Override
public boolean onScroll(MotionEvent from, MotionEvent to, float distanceX, float distanceY) {
    System.out.println("test");
    return true;
}
});

When I set it before the .start(), I have the same behavior and there's no log. The drawing is showing but it's just a mess of line below my finger since the map is paning.
When I set it after, no drawing is showing, the test log is shown and the pan is desactivated.

Have you tried overriding

public boolean onTouch (View view, MotionEvent event)

https://developers.arcgis.com/android/latest/api-reference/reference/com/esri/arcgisruntime/mapping/view/DefaultMapViewOnTouchListener.html#onTouch(android.view.View, android.view.MotionEvent)

I have not had to get a chance to test this out as I was out the last two weeks or so. Additionally, this week may be tough as it is UC week (hopefully I will have a chance to review it soon)
