首先：一切工作完全按照預期的iOS中。鈦的Android應用程序崩潰，在更新ScrollableView
我相信這個問題是一些由鈦生成的Java對象沒有得到一個參數來更新可滾動視圖的大小。

當直接設置可滾動視圖的.views屬性或使用.setViews時（）碰撞發生的情況。
相關代碼：
//on scrolling of the Years view fill the makes and model views
function populateMake(e){
$.makeScrollableView.scrollToView(0);
removeAllChildren($.makeScrollableView);
//Generating URL
var selectedYear = $.yearScrollableView.currentPage; //selected index
var carYearViews = $.yearScrollableView.getViews(); //array of views
var children = carYearViews[selectedYear].getChildren(); //children of the selected year (aka the label w/ the year in it)
var makeYear = children[0].getText();
var url = "www.example.com";
var makeViews = [];
var client = Ti.Network.createHTTPClient({
onload : function(e){
var yearMakes = [];
yearMakes = parseMakes(this.responseText); //returns an array of strings
for(var i = 0; i < yearMakes.length; i++){
var yearLabel = Ti.UI.createLabel({
title: "year",
text: yearMakes[i]
});
var view = Ti.UI.createView({
backgroundColor: 'blue'
});
view.add(yearLabel);
makeViews.push(view);
}
$.makeScrollableView.setViews(makeViews); //<--- crashes here when scrolling $.yearScrollableView
populateModel();
},
onerror : function (e){
Ti.API.error("HTTP Error populating makes");
}
});
client.open("GET", url);
client.send();
}
和：
//populate model when year/make is changed
function populateModel(e){
$.modelScrollableView.scrollToView(0);
removeAllChildren($.modelScrollableView);
var selectedYear = $.yearScrollableView.currentPage; //selected index
var carYearViews = $.yearScrollableView.getViews(); //array of views
var childrenYear = carYearViews[selectedYear].getChildren(); //children of the selected year (aka the label w/ the year in it)
var carYear = childrenYear[0].getText();
var url = "www.totallyafakewebsite.net";
Ti.API.info(url);
var modelViews = [];
var client = Ti.Network.createHTTPClient({
onload : function(e){
var carModels = [];
carModels = parseModels(this.responseText); //array of strings
for(var i = 0; i < carModels.length; i++){
var modelLabel = Ti.UI.createLabel({
title: "model",
text: carModels[i]
});
var view = Ti.UI.createView({
backgroundColor: 'blue'
});
view.add(modelLabel);
modelViews.push(view);
}
$.modelScrollableView.setViews(modelViews); //<--- this is the crash when scrolling $.makeScrollableView
//$.modelScrollableView.views = modelViews; //doesn't work either
},
onerror : function (e){
Ti.API.error("HTTP Error populating models: " + e.error);
}
});
client.open("GET", url);
client.send();
}
當相應的滾動視圖滾動這些事件被觸發。
每個可滾動視圖都是在xml視圖中創建的。
