Touch event too hard to trigger on Android

[wvengen]

Thanks for adding proper Android support! It works quite well, but for one thing: a touch event requires holding the finger very still.

Consider the following components:

<Swipeout right={{component: 'MyButton', onPress: this._onMyButtonPress}} close={true}>
  <View>
    <TouchableHighlight onPress={this._onRowPress}>
      <... />
    </TouchableHighlight>
  </View>
</Swipeout>

On iOS this works fine, but on Android triggering the TouchableHighlight is very hard: only a slight movement of the finger during the press triggers the swipeout action, which makes _onRowPress hard to trigger.

trippcr@ce2b048 on 2.0.9 still works.

@dancormier: would it make sense to add an onPress to the Swipeout component?

The Swipeout onOpen function appears to be *** super *** sensitive on Android.

Is there any configuration for sensitivity?

I have to press a ListView row 4 or 5 times. I have to press very deliberate and straight and perpendicular to the tablet.

See:
#78

Using:
Android 6.0
Nexus 7 tablet
"react": "15.0.2",
"react-native": "^0.26.2",
react-native-swipeout@2.0.12

Using adb logacat, I can see that the _handlePanResponderGrant function gets called almost every time the ListView row is touched. Unless you press straight and quick ( not very easy ).

This seems to prevent the ListView row's onPress method being called. I assume until the gesture has ended?

https://github.com/dancormier/react-native-swipeout/blob/master/index.js

  _handlePanResponderGrant: function(e: Object, gestureState: Object) {
    console.log('_handlePanResponderGrant:', gestureState);
    if(this.props.onOpen){
      this.props.onOpen(this.props.sectionID, this.props.rowID);
    }
    this.refs.swipeoutContent.measure((ox, oy, width, height) => {
      this.setState({
        btnWidth: (width/5),
        btnsLeftWidth: this.props.left ? (width/5)*this.props.left.length : 0,
        btnsRightWidth: this.props.right ? (width/5)*this.props.right.length : 0,
        swiping: true,
        timeStart: (new Date()).getTime(),
      });
    });
  },

Perhaps there is someway to de-bounce or de-sensitive PanResponder to make it not detect a PAN gesture so easily? Set a deltaX or deltaY threshold?

I cannot find anything in the react-native PanResponder documentation.

set sensitivity to 1, it works for me

[esutton]

@chkchk Thank you!

I searched this repo for "sensitivity".

I see it being used but not referenced. How can sensitivity be doing anything?

I will give it a try anyway.

thanks @chkchk works for me too

[philographer]

It works for me too nicely! Thanks

Hi, I've tried setting sensitivity to 1 but it's not working for me on an android device. The touch event is incredibly difficult to trigger and requires me to press the list item a few times quickly to work.
It works perfectly on an iOS device.

The following is my renderRow code:

<Swipeout
    scroll={event => this._allowScroll(event)}
    sensitivity={1}
    autoClose={true}
    right={swipeoutButtons}>
    <TouchableOpacity
       style={styles.transaction}
       key={rowData.id}
       onPress={() => { this._goToScreen(rowData) }}>
         <View style={styles.listItemContainer}
            {...}
          </View>
     </TouchableOpacity>
 </Swipeout>

react-native 0.40.0
Samsung Galaxy S6
Android 6.0.1

Anyone knows what I might have done wrong?

Still hard to trigger onPress event of TouchableOpacity after set sensitivity to 1.
react-native 0.43.3
iPhone 6s

I just published extension of Swipeout to make it works like Android behavior on Android.
Try this.
