On pinch zoom end event?

Answered

I am using a PinchZoomModifier with my chart and I would like to execute some code when the user stops the zooming action (stops touching the screen). Is it possible to do? Are there any listeners I could attach to the PinchZoomModifier? I couldn’t find any in the docs.

Hi Miha,

Well there is no callback but you can extend PinchZoomModifier and override its onScaleEnd() method:

class CustomPinchZoomModifier extends PinchZoomModifier {
@Override
public void onScaleEnd(ScaleGestureDetector detector) {
    super.onScaleEnd(detector);

    //TODO
}
}

Is this suitable for your needs?

Best regards,
Yura

Yes that works, thank you. Is there anything similar for ZoomPanModifier, to know when the panning has ended?

Well you can override onUp() method which is called when touch gesture is ended

That would work on everything but the fling I guess?
