Question

我在Titanium的屏幕上工作，它有几个输入文本字段和标签以及一个继续按钮。在继续按钮单击我删除我的变量'容器'并添加一个不同的容器与不同的文本字段等。这是非常基本的，但在我的继续按钮单击事件，我得到随机崩溃，可能是60-70％的它崩溃的时间。它报告的错误就是那条消息，“不幸的是＆lt;＆gt;已关闭'。任何想法可能是什么？继续下面的按钮事件监听器，当我在调试模式下运行时，我正在进行崩溃3。日志似乎表明我有权拒绝，但实际上我所做的只是用不同的视图替换视图。我很难过：

var self = Ti.UI.createWindow({
        title:title,
        backgroundColor:'#33336F'
    });
var Container=Ti.UI.createView({
        top:'40dp',
        width:'100%' 
    });

    var Container2=Ti.UI.createView({
        top:'40dp',
        width:'100%' 
    });

Continue_btn.addEventListener('click', function (e){

    console.log('--------------------- '+ self);
    console.log('--------------------- Title_textfield val is '+Title_textField.value);
    console.log('--------------------- Trade_picker val is '+Trade_picker.getSelectedRow(0).title);
    console.log('--------------------- Urgent_image val is '+Urgent_image.image);

    Post_array.push({
        Title:Title_textField.value,
        Trade:Trade_picker.getSelectedRow(0).title,
        Urgency:(Urgent_image.image == "urgentChecked1.png")?"0":"1",
        ClientID:8
    });

    console.log("--------------- Post_array is " + Post_array[0].Title+' - '+ Post_array[0].Trade + ' - ' + Post_array[0].Urgent);
    console.log('-------- crash 1');
    Continue_btn.setBackgroundImage('/images/continue2.png');
    console.log('-------- crash 2');
    console.log("Is self val undefined ------ "+ self.value + " or is Container val undefined ----- "+ Container.value + " or is container 2 val unndefined ------ "+ Container2.value);
    console.log("Is self typeof undefined ------ "+ typeof self + " or is Container typeof undefined ----- "+ typeof Container + " or is container 2 typeof unndefined ------ "+ typeof Container2);
    self.remove(Container);
    console.log('-------- crash 3');
    self.add(Container2);
    console.log('-------- crash 4');
    Navbar.add(BackArrow_btn);
    console.log('-------- crash 5');

});

编辑更新了事件监听器和日志信息。我没有太多其他代码可以包含，只是标签，文本字段和选择器的声明被添加到容器视图和container2视图

你检查了“自我”的价值吗？您是否尝试通过变量名称而不是自我来删除容器并将其添加到主视图中？

//in Alloy
$.viewMain.remove( ... );
$.viewMain.add( ... );
//or JS
var viewMain = Ti.UI.createView(...);
viewMain.remove( ... );

删除导致应用程序崩溃的视图
