I am building a Kendo UI Mobile + AngularJS application. I have a listview with a variable number of results, could be anything between 5 and 500.
The scrolling of the listview on Android is bad. It is choppy and feels like it doesn't respond to the speed I give with my finger. I could do a fast slide up and it would slowly scroll down instead of fast.
Is this a known problem? Could it be something I am doing wrong? How can I fix this? Are there any scroll properties I could change?
listview view :
<kendo-mobile-view id="result" ng-controller='resultController' k-reload="true">
<kendo-mobile-header>
<section kendo-mobile-nav-bar class="navbar">
<kendo-mobile-view-title>{{::resultsLength}} {{::'res_header_result' | translate }}</kendo-mobile-view-title>
<kendo-mobile-button k-align="'left'" k-icon="'back'" ng-click="back()"></kendo-mobile-button>
<kendo-mobile-button ng-click="collapse()" k-transition="'slide:left'" k-align="'right'" k-icon="'sort'" data-toggle="collapse" data-target="#sortmenu" aria-expanded="false" aria-controls="collapseExample" style="margin-right:1em;"></kendo-mobile-button>
<kendo-mobile-button k-transition="'slide:left'" k-align="'right'" k-icon="'filter'" href="#view/filter.html"></kendo-mobile-button>
</section>

listview controller function
function getData(link) {
$scope.source = new kendo.data.DataSource({
type: "json",
transport: {
read: {
url: link
}
},
requestEnd: function(e) {
var results = e.response._embedded.offers;
getLocalStorage.addObjectToLocalStorage(results, 'results');
kendo.mobile.application.hideLoading();
},
schema: {
total: function(response) {
$scope.resultsLength = response._embedded.offers.length;
return $scope.resultsLength;
},
data: "_embedded.offers"
},
serverPaging: true,
pageSize: 16
});
$("#resultList").data('kendoMobileListView').setDataSource($scope.source);
};
I had this problem too. To solve it I initialized the kendo application like so:
if (isChrome()) { window.kendoMobileApplication = new kendo.mobile.Application($(document.body), { useNativeScrolling: true }); }
In other words it seems that if you are targeting android browser you need native scrolling.
