Suggestion: Add callback when focus is locked #153

Closed siralam closed 6 years ago

siralam commented 6 years ago

Let's say I want to play a shutter animation when the focus is locked / just before taking a picture.

I don't want to play it together with pressing the capture button because the camera needs time to lock focus.

Hope this feature will be added in the future!

Hey! While there are no general callback when camera is focused, you can get callback when you are triggering focus manually:

        fotoapparat.focus().whenAvailable { result: FocusResult? -> 
            Log.d("callback test", "focus now in $result state")
        }

But that does not help when taking photos and i agree, callback could be very useful. (As a workaround you could manually focus, then take photo, while disabling auto focus which triggers by photo - but that too is not possible yet, see #149 )

Plan is to remove the focus routine just before taking a photo (#149). Then you will be able to use the code @Raenar4k perfectly suggested.

I assume this issue solved. Will continue with #149 about takePicture/focus relation
