Question

我已经在钛工作室中构建了一个应用程序，我已经在iphone模拟器和iphone设备上运行它，它运行得很好。但是当我尝试在Android模拟器或Android设备上运行它时会崩溃。

我收到以下错误：

有没有人知道什么是错的？我会发布一些代码，但是太长了，我不知道哪个部分会导致这个问题。

等待你的回答，谢谢！

Answer 1

// this sets the background color of the master UIView (when there are no windows/tab groups on it)


//Ti.include('Window1.js');
Titanium.UI.setBackgroundColor('#000');

// create tab group


var placeHolders = [{left:10, top:10, width:20, height:20, bgColor:"#FFF", bgAlpha:0.5, img:""},
                    {left:30, top:20, width:50, height:50, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""},
                    {left:60, top:60, width:20, height:20, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""},
                    {left:100, top:20, width:20, height:20, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""},
                    {left:50, top:100, width:20, height:20, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""}
                    ];


var tabGroup = Titanium.UI.createTabGroup();





var parentWindow = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundImage:"assets/background.png",
    backgroundColor:'#fff',
    navBarHidden:true,
    tabBarHidden:true
});
addPlaceHolders();

function addPlaceHolders()
{
    for(i = 0; i < placeHolders.length; i++)
    {
        var placeHolder = placeHolders[i];
        var placeHolderView = Titanium.UI.createView({
            top:placeHolder.top,
            left:placeHolder.left,
            height:placeHolder.height,
            width:placeHolder.width,
            backgroundColor:placeHolder.bgColor,
            opacity:placeHolder.bgAlpha

        });
        placeHolderView.name = i;
        parentWindow.add(placeHolderView);
        placeHolderView.addEventListener("click", onPlaceHolderClick);
    }
}


var main = Titanium.UI.createTab({  
    title:'Tab 1',
    window:parentWindow
});
//  add tabs
tabGroup.addTab(main);  

// open tab group
tabGroup.open();

function onPlaceHolderClick(e)
{
    //tell me wot to do here
    alert("tell me wo to do here");
}
