Duration of a Single-Tap and Long-Tap in Android

Question

I'm trying to drag overlays an a map and also display an infobox if the user taps on a pin. To do so I need to measure the time between MotionEvent.ACTION_DOWN and MotionEvent.ACTION_UP. To make it feel as natural as possible I would like to know what value Android uses for a Single-Tap (currently I'm using 180ms) and also for a Long-Tap.

Thanks!

Answer 1

Android source uses 125ms for a single tap and 500ms as the long press time:

private static final int PRESSED_STATE_DURATION = 125;

private static final int DEFAULT_LONG_PRESS_TIMEOUT = 500;

ViewConfiguration.java#PRESSED_STATE_DURATION

ViewConfiguration.java#DEFAULT_LONG_PRESS_TIMEOUT
