Question

I have made an application in titanium framework for Google Maps. I have multiple locations on the map and which are shown as annotaion/pinpoints. I have taken click event of the annotation as well. Annotaions will show data in tableview in the next screen.when I am coming back to the Google Maps screen, I have to click back button twice rather than once.

Queries :

1) can any body help me out how to handle the back event which should come back by 1 click only instead of 2 clicks and which should not render the data 2 times on 2 clicks of back button.Here same screen appears 2 times for data on back button event.

2) If i have many annotations on the map, then how to get the information of the same/particular pinpoint/annotation , when it does the click event and should show data of pinpoint as tableview in the next screen.(i.e. if i have FOR LOOP and from that loop when it shows us the multiple annotation/pinpoint, all the annotation should get all the details and should shown its own data to the next screen tableview.)

Any useful code or link will be appreciated…!!!

I have given code snippet below :

mapview.addEventListener('click', function(evt) {
    var annotation = evt.annotation;
    var title = evt.title;
    var clickSource = evt.clicksource;
    // alert(annotation + 'tit'+title+'clickSource'+clickSource);
    // alert("Btn Pressed");

    if(evt.clicksource == 'rightButton') {
        Titanium.App.Properties.setString("latitude",latitude.item(0).text);
        Titanium.App.Properties.setString("longitude",longitude.item(0).text);
        Titanium.App.Properties.setString("city",city.item(0).text);
        Titanium.App.Properties.setString("address",address.item(0).text);
        Titanium.App.Properties.setString("OwnerInstitution",OwnerInstitution.item(0).text);
        Titanium.App.Properties.setString("TerminalDesc",TerminalDesc.item(0).text);
        Titanium.App.Properties.setString("State",state.item(0).text);
        Titanium.App.Properties.setString("Zip",Zip.item(0).text);
        Titanium.App.Properties.setString("Charge",Charge.item(0).text);

    var tab = Titanium.UI.currentTab;
        var win1 = Titanium.UI.createWindow({
            url:'ATMDetails.js',
            title:'ATM Details',
            // latitude:win1.latitude
        });
        tab.open(win1, {
            animated:true
        });
    }
});

For Issue 1 I am not getting your point correctly.

For Issue 2- As i understand, you want to show the detail of particular annotaion where the user clicked.
Solution:
The function where you load all the information using for loop define an array which should store the data of specific anotaion. like

annotations = []; //updated
for (i=0; i < yourfeedsData.length; i++) {

      var detailData= [];

        //Your data
         var latitude =   latitude.item(0).text;
         // all list of your data .......


        // creating annotaions 
        var annotaion = Titanium.Map.createAnnotation( { 
                 title:'Your title',
                animate:true
            });  

      // pushing the data to array ..... all your values like,
      detailData.push({lat:latitude,...... });

      // setting data to your annotaion object
      annotaion.detailData=detailData; 

      // creating annotation array
          annotations[i] = annotaion ; //updated
     }

    your_mapView.addAnnotations(annotations); // updated

and in your click event, get the annotation data and pass it to detail your window. And use that detail data to show in list.

 // get the detail data
    var detailData = evt.annotation.detailData;
 if(evt.clicksource == 'rightButton') {

                var tab = Titanium.UI.currentTab;
                var win1 = Titanium.UI.createWindow({
                    url:'ATMDetails.js',
                    title:'ATM Details',
                    //latitude:win1.latitude
                });
               // PASS THE DATA TO YOUR WINDOW  
               win1 .detailData = detailData;

                tab.open(win1, {
                    animated:true
                });

}
