Answer 1

It's all explained in the documentation of JsonDataAccess. You'll have to do something like this:
// Create a data model with sorting keys for title
GroupDataModel *model =
new GroupDataModel(QStringList() << "title");
// Load the JSON data
JsonDataAccess jda;
QVariant list = jda.load("yourfile.json")["result"].toVariantList();
// Add the data to the model
model->insertList(list.value<QVariantList>());
// Add your model to a ListView
listView->setDataModel(model);

Answer 2

This is the QML way of doing it, you don't have to touch any C++ code.
First you need to create a listview in a QML file.
ListView {
id: listData
dataModel: ArrayDataModel {
id: theDataModel
}
....
}
Now you will want to populate your listview with the data from a json file. Since you are making a call to the server, you will want to send a request.
function sendRequest() {
console.log("DEBUG: sending request");
var request = new XMLHttpRequest();
request.onreadystatechange = function() {
// Need to wait for the DONE state or you'll get errors
if (request.readyState === XMLHttpRequest.DONE) {
if (request.status === 200) {
// if response is JSON you can parse it
var response = JSON.parse(request.responseText);
theDataModel.append({
"offer_id": response.result.offer_id,
"member_id": response.result.member_id,
"offer_type": response.result.offer_type
});
}
} else {
// Error
console.log("DEBUG: Status: " + request.status + ", Status Text: " + request.statusText);
}
}
// POST/GET request
request.open("GET", "http://www.example.com/json.php", true);
request.setRequestHeader("Accept", "application/json");
request.send();
}
And to display the values, you can use StandardListItem:
StandardListItem {
title: ListItemData.offer_id
description: ListItemData.offer_type
status: ListItemData.member_id
}
