Sencha Touch 2- Performance: profiles - list overscroll on Android and class number

[alexdran]

Hello All,
I have a sencha touch 2 app and I would like to stop overscroll on Android device for a better performance in list display

Now my question is: if I'm doing it by creating profiles android classes with blocked list and general classes with overscroll do I risk to double the number of classes loaded by the App hampering again performances?


thank you in advance for your advice in this
Alessandro!!!

You can disable the bounce affect (overscroll) via this on the list:

scrollable : {
    direction                : 'vertical',
    momentumEasing           : {
        momentum    : {
            acceleration : 30,
            friction     : 0.5
        },
        bounce      : {
            acceleration  : 0.0001,
            springTension : 0.9999
        },
        minVelocity : 5
    },
    outOfBoundRestrictFactor : 0
}

I know already the code from one of the previous forum post, thank you

my question is wether i need to create profiles (for android and non android devices) in order to keep the nice overscroll on iphone device and thus is

with profiles I risk to double the classes loaded by the framework at startup mining again performance from another side


thank you again for support

You don't really need to, you can set this variably in a list definition using the applyScrollable method.

But, by doing this would be method be applied also for iphone devices (preventing the nice overscroll effect so effective there and that users are used to)??

thank you again for clarification
