I am new from Oracle MAF. In my task flow 5 fields are there. The first one in Questionnaire page.
In this questionnaire page:
create Questionnaire
List Questionnaire
Search Questionnaire
Reports
these four fields are there. If I click any one of the field, I want to go that page. Like if I click create Questionnaire, I want to go to create Questionnaire page.
Please help anyone how can I do this. I am using the following code for taskflow:
<?xml version="1.0" encoding="windows-1252" ?>

Use an AMX component that has the action attribute.
Example:
<amx:commandLink id="commandLink1" text="create Questionnaire" action="create" />
Where action is the name of you control flow case in your task flow.

I used TouchableOpacity on icon and Gave Elevation to Touchable Opacity which is on image carousel, Its Not working. Please Help
I got the answer by experimenting myself; In Order To get Touchableopacity on icon over Image Carousel, we just need to use 'zIndex=3' Not 'elevation'.
For example I want the body element not to scroll
But one of its containing elements should be scrollable
I have used ScrollView and View element from react native but I don't get any scroll within my scroll view. I have switched off scroll on the body to isolate the scroll view to no effect.
You have to give flex:1 to the parent component of Scroll View .
For Ex:
<View style={{flex:1}}>
<ScrollView contentContainerStyle={{ flexGrow: 1 }}>
<View>
{whatever you want to scroll}
</View>
</ScrollView>
</View>
I've managed to load an image from the web into my app but have an issue...
I have some local data about food. each food item has a food title, and a url to a picture online.
This is the Image component that lives inside my foodComponent.
<Image style={styles.cardImg} source={{uri:image}} />
image is a string to a url that is passed as a prop to this foodComponent.
Again it works but my problem is that the image takes time to load.
How could I only render the foodItem component once it has received/loaded an image?
I know about promises but I don't see how I could use it in this scenario.
here is my entire foodItem component:
export default function FoodItemTouchable(props){
return(
<View style={styles.container}>
<View style={styles.card}>
<View style={styles.cardHeader}>
<Text style={styles.text}>{props.item.title}</Text>
</View>
<Break/>
<CardImage image={props.item.url}/>
</View>
</View>
)
}
function Break() {
return(
<View style={{alignItems:'center'}}>
<View style={styles.break}>
</View>
</View>
)
}
function CardImage({image}){
return(
<View style={{padding:10,width:'100%'}}>
<Image
style={styles.cardImg}
source={{uri:image}}
/>
</View>
)
}
CardImage is where the image gets rendered.
the rest of the Components render first but the CardImage is delayed because it's loading the image.
If I could somehow load the image into a variable in the main Component,
and then there do a check, is image===null ? return null
so that the component renders only when the image is ready.
Have you tried like this?
{
props.item.url
&&
<CardImage image={props.item.url}/>
}
I've been struggling on how to handle memory allocations on my Titanium app (built for android [9.4MB], ios[2.8MB] and MobileWeb[5.4MB].
I have created a widget which will be use to open views from a menu selection.
<Alloy>
<Window id="mainWindow">
<View id="menuView">
<View id="vTop">
<!-- Header goes here -->
<TableView id="menuTable" />
</View>
<!-- footer message goes here -->
</View>
<View id="contentView">
<View id="nav">
<Label id="winTitle"/>
<View id='leftButtonView'>
<Label id="icoLeftButton" />
</View>
<View id='backButtonTitleView'>
<Label id="icoBack" />
<Label id="backButtonTitle" />
</View>
<View id='rightButtonView'>
<Label id="icoRightButton" />
</View>
</View>
<View id="mainView" layout="composite" />
</View>
</Window>
</Alloy>
Sample usage of this widget:
I was able to reduce the memory allocations of views by following this solution. I've applied this every time I open another view from menu selection.
(controller of my widget)
var memPool = Ti.UI.createWindow();
memPool.open();
memPool.hide();
memPool.close();
// Open view from menu selection
function openView(e) {
var cbAdd = function() {
var ctrl = Alloy.createController(e["url"]);
if (ctrl != null) {
setWindowTitle(e["wTitle"]);
setRightIco(ctrl.getRightIco()); //setting right label icon (IcoMoon font)
$.setRightNavClick(ctrl.getRightNavCb());
//Have to passed navGroup to be able to open other views
ctrl.winMain.navGroup = $;
//Close splash screen after layout
ctrl.winMain.addEventListener("postlayout", postLayout);
$.mainView.add(ctrl.winMain);
ctrl.init();
ctrl = null;
}
};
var cbRemove = function() {
//Remove all children from mainView; fn [commonjs]
fn.removeChildren($.mainView, cbAdd);
};
if ($.mainView.children.length > 0) {
cleanUp($.mainView.children[0]);
cbRemove();
} else
cbAdd();
}
function cleanUp(obj, cb) {
memPool.open();
memPool.hide();
memPool.setZIndex(-1);
memPool.add(obj);
memPool.close();
obj = null;
if (cb != null) cb();
}
Checking the result on XCode Instruments:
TiUIView is always reduced everytime I open other views from menu but TiUIViewProxy doesn't.
Sample View to be open: (consist of widgets)
<Alloy>
<View id="winMain">
<ScrollView id="form" layout="vertical">
<Widget id="fperiod" src="ph.com.test.controls.period" top="10" />
<Widget id="ftermid" src="ph.com.test.controls.key" label="Terminal No." top="20" />
<Widget id="fofficeid" src="ph.com.test.controls.combobox" label="Branch" />
<View id="btnReset" width="100%" height="50" layout="horizontal" top="20" bottom="20" backgroundColor="#B40026">
<Label class="resetFilter" />
<Label class="lblReset" />
</View>
</ScrollView>
</View>
</Alloy>

How to reduce the memory allocations of TiUIViewProxy? Do I have to also cleanup the views of widgets from its controller?
I have tried to cleanup the views of my widgets from its controller. Then, the TiUIViewProxy is somewhat reduced as per checking it on XCode Instruments but my problem is that my app suddenly crashes. I don't know why. Or I'm not just doing it right. Sample clean up function from my widget:
$.cview.remove($.formItemLabel);
$.cview.remove($.lblValue);
$.mView.remove($.cview);
//nulling controller variables goes here
mData = null;
animateLeft = null;
...
This is a really great article on memory management, I follow these guidelines for my own development purposes and highly recommend you read through this.
Memory Management
http://www.tidev.io/2014/03/27/memory-management/
I am using the Alloy MVC framework over Titanium and want to make a slideshow between views. When I swipe on the screen, I want to display the next/previous view with a slide effect from right to left or left to right.
I am using this code:
A tab in my index.xml:
<Tab title="Bilan" icon="KS_nav_ui.png">
<Window title="Bilan" id="bilanTab" onSwipe="doBilanSwipe">
</Window>
</Tab>
The question view dynamically added and filled inside bilanTab:
<Alloy>
<Collection src="ReponsePossible">
<View id="questionContainer" class="container">
<Label id="questionText" />
<Button id="buttonNextQuestion">Question suivante</Button>
</View>
</Alloy>
and my two functions (3 with prevQuestion not printed here) inside index.js controller:
var previousQuestion;
var nextQuestion;
function doBilanSwipe(e){
if (e.direction == 'left'){
nextQuestion();
}
else if (e.direction == 'right'){
prevQuestion();
}
}
function nextQuestion(){
if (questionsCurrentIndex < questions.length-1){
questionsCurrentIndex++;
$.previous = previousQuestion;
$.next = Alloy.createController('question', questions.at(questionsCurrentIndex));
nextQuestion = $.next;
$.next.questionContainer.left = 320;
$.bilanTab.add($.next.questionContainer);
$.next.questionContainer.animate({left:0, duration:200});
$.previous.questionContainer.animate({left:-320, duration:200},function(){
$.previous = previousQuestion;
$.next = nextQuestion;
$.bilanTab.remove($.previous.questionContainer);
previousQuestion = $.next;
$.previous.destroy();
});
}
}
My problem is that first animation (first view moving to the left) is ok but after that, the next view just appear without any animation.
Could someone help? Thanks!
There is already the Titanium.UI.ScrollableView that does this exact thing, for all platforms.
Use it in Alloy like this:
<Alloy>
<Window id="win">
<ScrollableView id="scrollableView" showPagingControl="true">
<View id="view1" backgroundColor="#123" />
<View id="view2" backgroundColor="#246" />
<View id="view3" backgroundColor="#48b" />
</ScrollableView>
</Window>
</Alloy>
You can dynamically add views to it inside the controller like this:
$.scrollableView.addView(Ti.UI.createView({ // your custom attributes here});
