onLongPress (and delayLongPress) triggers immediately

[yonatanmn]

For some reason (I have no clue why) onLongPress triggers immediately, and onPress doesn't.
tested on : android simulator with genymotion (galaxy5) and real galaxy3 device

After adding delayLongPress i figured out that it's "stealing" 1000ms from the delay, and I guess the default delay is 1000, so it's triggering immediately.

for example :

  <TouchableOpacity      
               delayLongPress={3800}
               onPress={()=>{
                  console.log(' onPress');  
                  console.log(Date.now())}}
               onPressIn ={()=>{
                  console.log('TouchableOpacity onPressIn'); 
                  console.log(Date.now())
                }}
               onLongPress ={(e)=>{
                  console.log(' onLongPress');
                  console.log(Date.now());
                  console.log(e.type); //undefined
               }}
           >

when I calculate : onLongPress time - onPressIn time , I get ~2800ms
without delayLongPress or with delayLongPress={1000} I get 10-20ms

Duplicate of this? #4088

[yonatanmn]

Looks like the same problem,
closed dev-tools (and added other display - not console.log) and it's working fine

[jozn]

+1 when i debugging in chrome i see this behavior.

[yonatanmn]

similar thing happens for ScrollView.onScroll- also blocking the scroll

[martincox]

I tried to investigate this problem but could not replicate the behaviour. I used the example code provided by @yonatanmn and the onPress and onLongPress fired as expected.

Is there more to this, or has it been fixed?

[christopherdro]

Confirming that this happens only with chrome debugger enabled.

[IjzerenHein]

Also confirming that this happens only with chrome debugger enabled.

[nicastelo]

Same. Confirming that this happens only with chrome debugger enabled.

[sharnik]

I've just tested that and it looks like it's reversed now ;)

Without debugging tools the longPress triggers after holding for ~500-600ms, but with Chrome debugging open you need to wait ~3400ms.

I don't know whether it's a bug or a feature, but it seems that the original problem (launching onLongPress instead of onPress) has been solved.

ExceptionsManager.js:71 Attempted to transition from state RESPONDER_INACTIVE_PRESS_IN to RESPONDER_ACTIVE_LONG_PRESS_IN, which is not supported. This is most likely due to Touchable.longPressDelayTimeout not being cancelled.reactConsoleErrorHandler @ ExceptionsManager.js:71console.error @ YellowBox.js:61_handleLongDelay @ Touchable.js:596proxiedMethod @ createPrototypeProxy.js:44(anonymous function) @ JSTimers.js:80callTimer @ JSTimersExecution.js:95callTimers @ JSTimersExecution.js:136__callFunction @ MessageQueue.js:236(anonymous function) @ MessageQueue.js:108guard @ MessageQueue.js:46callFunctionReturnFlushedQueue @ MessageQueue.js:107onmessage @ debuggerWorker.js:44

Hmm it randomly started happening, after testing on real device with RN Debugger. it was working fine, and suddenly stopped working, onLongPress is being called on quick single tap instead of onPress.

[battuashwik]

Im seeing this issue too.

[ThisIsMissEm]

@brentvatne @satya164 How can I help? (I'm seeing this, and it's causing me issues with my workflow, and also may be resulting in the app just randomly exiting).

[skhan02]

i am seeing this issue as well

[loune]

I've just encountered this issue as well when debugging on Android. React Native 0.43.4. I think this is due to #4470 The default press delay is 130ms and long press delay 470ms. This means that to be considered for a normal press, the release event needs to come before 600ms. If I log the Touchable events I see this:

1493638393648 RESPONDER_GRANT
1493638393694 DELAY
1493638393696 LONG_PRESS_DETECTED
1493638393716 RESPONDER_RELEASE

DELAY fires 46ms after press, not 130ms which what is supposed to happen. LONG_PRESS_DETECTED fires 48ms after press, not 600ms, then release comes 68ms.
This shows that there's something wrong with setTimeout, which is noted in #4470 - although it's marked as fixed, I'm not confident it is.

Also, notice that DELAY and LONG_PRESS_DETECTED is so close together - that's because the two setTimeout calls are made simultaneously but with different timeouts (130, 600). However, this bug makes them fire really close together, and sometimes flipped around, which causes bugs like #1693 which @zyxcambridge mentioned above

This is with no debugging, which is much more reasonable:

1493639762975 RESPONDER_GRANT
1493639763124 DELAY
1493639763492 LONG_PRESS_DETECTED
1493639764786 RESPONDER_RELEASE

Hi there! This issue is being closed because it has been inactive for a while. Maybe the issue has been fixed in a recent release, or perhaps it is not affecting a lot of people. Either way, we're automatically closing issues after a period of inactivity. Please do not take it personally!

[pocesar]

it's been inactive but still happening and should not be closed. it's even worse lately when using react-native-router-flux because it brings up a red box when transitioning between scenes with the error mentioned by @zyxcambridge

[foufee]

I started seeing this today too...using react native, and RNRF too.

[digitalmaster]

Confirmed.. this is still happening. Only when dev tools is connected tho.

[Athosone]

Yes still happening.. (i am on ios)
Was working fine yesterday and today bam...

[oakis]

The opposite happens to me. onLongPress takes around 2 seconds to fire, regardless of delayLongPress time. If I turn off remote debugging it is working as expected.

Edit: Actually in my case it was a firebase async call that caused the delay.

[themakerman]

+1 happening only with chrome debugger. I hope this doesn't happens in production.

[whylifes]

A competition

[whylifes]

hello,I am go away!

[whylifes]

forgive

[ricklove]

Ah, I thought I broke everything. Thankfully it's just because of Chrome debugger.

Works fine when I disable debugger. (Using Expo)

[gorvinsky]

Still having this issue and only happen when connected to Chrome debugger.

[ghost]

This breaks only when debug JS remotely is enabled. im using VSCode debugger.
this needs to be reopened

[james-lopez]

maybe a obvious mistake on my part but i was not passing onLongPress a function initially i was declaring a method instance which caused it to fire on load.

<TouchableWithoutFeedback onLongPress={this.someHandlerFunction}/>

whereas it should be

<TouchableWithoutFeedback onLongPress={() => this.someHandlerFunction}/>

[ricklove]

@apn-james both of those should be ok (what might be missing in the first is a bind function unless that is an arrow function instance).

Did you write the first call with parans maybe?

<TouchableWithoutFeedback onLongPress={this.someHandlerFunction()}/>

[james-lopez]

@ricklove true i did pass params and did not bind the first instance.

[Gennady77]

The same problem while remote debugging.

[PaulPourtout]

Still happening randomly (but at high frequency) on external device when remote debbuger is on. Tested it on Android devices only not sure if it happens on iOS.
