1.) Push all files from location one time in an array (if u change the folder, clear the array and push again ;))

2.) define are variable like currentImagePosition = 0

3.) If u open a random picture iterate the array until the image what you show is the same like in your array and store the position into currentImagePosition

4.) with currentImagePosition-1 and currentImagePosition+1 u get know always the previous and next item

5.) Dont forget to add special behaviours for no presuccessor and no successor.

Hi,

seems you want to implement a Carousel style image view, like the bootstrap Carousel. I think you can find many sample code on internet and porting it to tizen web app platform.

regarding how to get the images on device, you can use the filesystem api to get the images.

Hello,

try to use the following code to get the images from device. 

// Retrieve the ContentManager interface instance using the tizen global object
var manager = tizen.content;

// Let's try to retrieve the list.
var contentType = "IMAGE";
var filter = new tizen.AttributeFilter("type", "EXACTLY", contentType);
manager.find(mediaItemArray, onError, null, filter);

function onError(response) {
    console.log( "The following error occurred: " + response.name);
}

function mediaItemArray (contents) {
    var itemsList = document.getElementById('list');
    console.log("Successfully retrieved the list of Image items");

    for (var i=0; i < contents.length; i++) {
        console.log(i + ":" + contents[i].type + ":" + contents[i].title + ":" +contents[i].mimeType);

        var listItem = document.createElement("li");
        listItem.innerHTML = contents[i].title;

        itemsList.appendChild(listItem);
    }
}

Hi,

probably CompositeFilter can solve this problem. Try something like this:

var contentType = "IMAGE";
var imageFilter = new tizen.AttributeFilter("type", "EXACTLY", contentType);
var folderFilter = new tizen.AttributeFilter("contentURI", "CONTAINS", "Camera");
var filter = new tizen.CompositeFilter("INTERSECTION", [imageFilter, folderFilter]);
manager.find(mediaItemArray, onError, null, filter);

more info could be found here: https://developer.tizen.org/dev-guide/2.3.1/org.tizen.web.apireference/html/device_api/mobile/tizen/tizen.html#CompositeFilter

 

or you can just add if statement, like:

for (var i=0; i < contents.length; i++) {
    if (contents[i].contentURI.indexOf("Camera") != -1) {
        console.log(i + ":" + contents[i].type + ":" + contents[i].title + ":" +contents[i].mimeType);

        var listItem = document.createElement("li");
        listItem.innerHTML = contents[i].title;
        itemsList.appendChild(listItem);
    }
}

Where "Camera" is required folder name

Hello,

You do not need to implement additional functionality to your application. You can use ready-made solutions - Gallery (image viewer). For this purpose you can use App Control functionality.

Palitsyna

Hello,

As AVSukhov said, you can use Application Control functionality. Here you can find the useful link about App Control:

Developer Guide: https://developer.tizen.org/development/guides/web-application/tizen-features/application/application

I think he wants to open the image directly in the app. Also u have on appControl no functionally of swipe to see the previous or next image in of the folder ;) As far I understand.

So my solution is the right why... But I didnt submit any code, because the "kumars" should able to write it by yourself.

AVSukhov

Hello,

Ok =), f.e. tomorrow the user wants to image can be zoomed and/or removed from view state and further more slideshow and details view... 

and the developer will overload application this functionality (which is often non-trivial task).  Why do all that when developer can use already prepared solution (Gallery app).

imho =)

Marco Buettner

Yeah ... I know what you mean ... Maybe some developer think they can it do better =D
