Here is my code

main.qml

import bb.cascades 1.0

Page {
    content: Container {
        id: mainContainer
        objectName: "container"
        // property alias selectedText: selectedTextField.text
        //property alias deselectedText: deselectedTextField.text
        ListView {
            objectName: "listView"
            dataModel: XmlDataModel {
                source: "models/items.xml"
                id: model
            }
            listItemComponents: [
                ListItemComponent {
                    type: "item"
                    StandardListItem {
                        title: ListItemData.title
                    }

            ]
        }
        TextField {
            id: selectedTextField
            objectName: "selectedTextField"
            text: ""
        }
        TextField {
            id: deselectedTextField
            objectName: "deselectedTextField"
            text: ""
        }
    }
}

 app.cpp

#include "app.hpp"

#include <bb/cascades/Application>
#include <bb/cascades/QmlDocument>
#include <bb/cascades/AbstractPane>
#include <QDebug>

using namespace std;

using namespace bb::cascades;
QObject *textFieldSelected ;
QObject *textFieldNotSelected;
QObject *list;
App::App() {
	QmlDocument *qml = QmlDocument::create("main.qml");
	AbstractPane *root = qml->createRootNode<AbstractPane>();
	list = root->findChild<QObject*>("listView");
	textFieldNotSelected = root->findChild<QObject*>("deselectedTextField");
	textFieldSelected = root->findChild<QObject*>("selectedTextField");
	QObject::connect(list,SIGNAL(selectionChanged (QVariantList, bool)),this,SLOT(changeText(QVariantList, bool)));
	Application::setScene(root);
}

void App::changeText(QVariantList indexPath,bool selected) {
	

}

 app.hpp

#ifndef APP_H
#define APP_H

#include <QObject>
#include <bb/cascades/DataModel>
#include <bb/cascades/ListView>

/*!
 * @brief Application GUI object

class App : public QObject
{
    Q_OBJECT
public:
    App();
public slots:
void changeText(QVariantList ,bool );

};

#endif // ifndef APP_H

Try this.

void App::changeText(QVariantList indexPath,bool selected) {
    XmlDataModel *model = (XmlDataModel *)list->dataModel();
    QVariantMap map = model->data(indexPath).toMap();
    // map is your data in QVariant
    qDebug() << map["title"].toString();
}

hi,

It is working fine.Thank u verymuch.

[Pallam_Madhukar]

you can also try this,

listview->dataModel().data(indexPath).toMap()["title"].toString();
