How to refresh the arraylist on MAF UI

Hello

I'm developing an application of MAF with Jdev 12.1.3.0.0.

I have a listView on my page of amx. This is value bound to an arraylist (ArrayList < String >) in the bean support. There is an event of action on the page, which adds items to the ArrayList instance.

My problem is, I'm not able to update the display of the list on my user interface.

Newspapers, I am able to see the event method called as well as a list of Board action is changed.

But that updated the arraylist reflects not on my user interface.

Here is my code snippets:

---------------------------

the amx page:

< amx:listView var = value ' row' = "#{TripsBacking.refreshtimelist}" showMoreStrategy = 'autoScroll' bufferStrategy "viewport" id = "listView1" = > "

< amx:listItem id = "SDp" showLinkIcon = "false" >

< amx:outputText value = "#{line}" id = "ot1" / >

< amx:actionListener id = binding = "#{TripsBacking.pullToRefresh"al1"}" type = "swipeDown" / > "

< / amx:listItem >

< / amx:listView >

---------------------------

Backing bean:

public class TripsBacking {}

ArrayList < String > refreshtimelist;

Transitional public PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport (this);

Transitional public ProviderChangeSupport providerChangeSupport = new ProviderChangeSupport (this);

{} public void setRefreshtimelist (ArrayList < String > refreshtimelist)

ArrayList < String > old_value = this.refreshtimelist;

This.refreshtimelist = refreshtimelist;

propertyChangeSupport.firePropertyChange (old_value, "refreshtimelist", refreshtimelist);

providerChangeSupport.fireProviderRefresh ("refreshtimelist");

}

public ArrayList < String > getRefreshtimelist() {}

Return refreshtimelist;

}

public TripsBacking() {}

refreshtimelist = new ArrayList < String > ();

refreshtimelist. Add (Calendar.GetInstance () .getTime (). ToString());

}

{} public void pullToRefresh (ActionEvent actionEvent)

Calendar c = Calendar.GetInstance ();

Date d = c.getTime ();

ArrayList < String > templist = getRefreshtimelist ();

System.out.println ("date:" + d);

templist. Add (d.ToString ());

setRefreshtimelist (templist);

}

{} public void addPropertyChangeListener (PropertyChangeListener l)

propertyChangeSupport.addPropertyChangeListener (l);

}

{} public void removePropertyChangeListener (PropertyChangeListener l)

propertyChangeSupport.removePropertyChangeListener (l);

}

}

------------------------------

I will surely provide more information if necessary.

Ask for your help to solve this problem. Thank you.

Thank you

Tejas desrousseaux

Hi Tejas,

you declare a variable of providerChangeSupport, but you need to add public methods to support:

    public void addProviderChangeListener(ProviderChangeListener l) {
        providerChangeSupport.addProviderChangeListener(l);
    }

    public void removeProviderChangeListener(ProviderChangeListener l) {
        providerChangeSupport.removeProviderChangeListener(l);
    }

You must move the providerChangeSupport.fireProviderRefresh ("refreshtimelist"); calling the method "pullToRefresh" (after the call to the set method).

If you trigger the refresh, the entire list is reloaded. If you want to refresh only new posts, you must use the method providerChangeSupport.fireProviderCreate (Oracle Fusion Middleware Java QAnywhere for Oracle Mobile Application Framework).

    Hello

    Please can someone tell me how to refresh the entire screen?

    Refresh here means clear all fields and show empty fields.

    Thank you

    Hey,.

    as I usually do, is to create a separate function that manually assigns to each field and property reverts to its original state. There is not a function that does it for you. You must create your own. hope that helps good luck!

  • How to refresh the contents of a SimpleList?

    Hello

    I want to refresh the contents of a SimpleList. Unfortunately there is no method of clearAll() and no size() method. So no idea on how to do it?

    OK, you use 6.0...

    Well, if you are using SimpleList, you only display string, right? So, you can use remove() to remove an item from your list. This code allows to clear your list:

    int row = 0;
    try {
      your_list.remove(index);
      index++;
    } catch (IllegalArgumentException ex) {
    }
    

    Or you can use the set() method to update an existing line...

    I'm having a jspx page where I want to display the value from a bean class Get accessor...

    the Get accessor returns a list Arrarylist

    and I want to display the list of table in its entirety on the jspx page when it is loaded.

    Thank you

    You can use or in an ADF Faces page to iterate over the items returned by the method getMyList() of the bean:

    
      
    
    

    If you want to browse the internal lists, then use a nested iterator:

    I want to get the screen like this: the screen has an EditField and ListField. After that I have enter a word editfield and click enter, then the listfield will be updated, refresh the screen. The code below:

    public class malls extends screen implements {FocusChangeListener}
    private CustomeManager cManager;
    private LabelField titalField;
    find the EditField private;
    Private TreeField neayby;

    cManager = (CustomeManager) getDelegate ();
    titalField = new LabelField ("SGMalls");
    find = new EditField("","Find:");
    find.setFocusListener (this);
    girdles you = new VerticalFieldManager (Manager.VERTICAL_SCROLL |) Manager.VERTICAL_SCROLLBAR);
    GIRD. Add (titalField);
    GIRD. Add (Find);
    treeCallback = new TreeCallback();
    neayby = new TreeField (treeCallback, TreeField.FOCUSABLE);
    int nod = neayby.addChildNode (0, "NeayBy");
    neayby.addChildNode (nod, "Northpoint");
    label is new LabelField ("list of shopping malls");.
    listCallback = new ListCallback();
    mallList = new ListField() {}
    protected boolean touchEvent (TouchEvent message)
    {

    If (message.getEvent () == TouchEvent.Click & message.getEvent ()! = TouchEvent.Down)
    {
    String mallName = listCallback.get (mallList, getSelectedIndex()) m:System.NET.SocketAddress.ToString ();
    UiApplication.getUiApplication () .pushScreen (new MallContent (mallName));
    }
    Return super.touchEvent (message);
    }
    };
    mallList.setCallback (listCallback);
    VerticalFieldManager gridmanager = new VerticalFieldManager (Manager.VERTICAL_SCROLL |) Manager.VERTICAL_SCROLLBAR);
    for (int i = 0; i)<>
    {mallList.insert (i);
    Mall of chain = "Mall" + i;
    listCallback.Insert (mall, i);
    }
    GridManager.Add (mallList);
    cManager.setfirstField (gird);
    cManager.setsecondField (neayby);
    cManager.setthirdField (label);

    storeItem private MenuItem = new MenuItem ("Search Store", 100, 10)
    {public void run() {}
    UiApplication.getUiApplication () .pushScreen (new store());
    onClose();
    }
    };
    protected void makeMenu (menu Menu, for example int)
    {
    menu. Add (storeItem);
    }

    I hope the focusChanged method can get to the screen
    ' Public Sub focusChanged (field field, int eventType)
    {V VirtualKeyboard = getVirtualKeyboard();}
    Field f = getFieldWithFocus ();
    if(f==Find)
    {
    v.setVisibility (VirtualKeyboard.SHOW);
    String text = find.getText ();
    If (text.length > 0 () & text.charAt (text.length () - 1) == '\n') {}
    listCallback.erase ();
    mallList.insert (5);
    listCallback.Insert ("New", 5);
         
    cManager.invalidate ();
    }
    }
    else {}
    v.setVisibility (VirtualKeyboard.HIDE);
    }
    }
    }

    Instead of using FocusChangeListener, you can use FieldChangeListener or manage the click on the trackball by substituting invokeAction()

  • How to refresh the listview that is in another function

    Hi all,
    I have a problem with a refreshing of the listview.

    I have 3 features in the application, let's say 'feature A' 'feature B' and 'C'.

    I also have 2 tables and sqlite db (local) .and 1 view their names are 'A table', 'table B' and 'see C.

    View C is like this:

    create view C as

    Select a.oneColumn

    Table has a

    Union

    Select b.oneColumn

    Table B b;

    Each function has the main amx.page and each of them has listview values from the (local) sqlite DB.


    According to A, I can add new row to the database (line update or delete) and the list is updated with the help of the "ProviderChangeSupport".

    Same thing happens in the function (B) everything is ok so far. But according to C, there also listview. When I delete operation or update functionality or B.

    the listview in C function is not updated.


    I hope you all can easily understand the problem and help me with the solution. Oracle Mobile Application Framework.

    Hello

    you need to reset a feature - navigating it--you want to ensure the functionality and so refreshes the view. The change of supplier support works in the ClassLoader (feature film) it is issued to. You can use a listener to refresh the controls collection of data used by a list, but it does not work automatically.

  • How to refresh the result iterator to uncommitted changes

    Hello

    JDev 11.1.2.4

    I have a VO with a VC. In my AM I exposed 2 VO:

    VO1 = VO without the VC

    VO2 = VO with the VC

    I have in my user interface:

    VO1-based array in which I can add, update, or delete rows.

    a button that shows a popup that contains a table based on VO2

    Scenario: update

    I make a modification on an existing line. The change is made on automatic transmission of true - field.

    I click on the button

    The table on the shortcut menu shows the changed value

    Ok

    Scenario 1: create

    I have create a new line. Fields to create the new line are all send auto = true

    I click on the button

    The table on the shortcut menu does not show the new line. It shows only the last State (original + changed lines lines)

    KO

    Scenario 1: remove

    I delete an existing line.

    I click on the button

    The table on the shortcut menu does not show the deleted row. It shows only the last State (original + changed lines lines)

    KO

    Q: what can I do, for the table on the shortcut menu shows the current status (non-validated data). I tried to refresh the iterator after a creation or deletion, but I still get the old data?

    DCIteratorBinding myIterator = ADFUtils.findIterator (iterator);
    myIterator.executeQuery ();
    myIterator.refresh (DCIteratorBinding.RANGESIZE_UNLIMITED);

    Thank you

    It depends on the vo and the Victoria Cross. The two vo must rest on the same area of occurrence. The Victoria Cross should have mode query so (memory and db) and the Victoria Cross on the second vo should be in a way that the new line would be part of the result set if given th could be read from db.

    The selected channels do not lead to the necessary result. New record in the table is displayed. But it is not displayed in the list on the screen.
    Moreover, the regeneration of the page through a browser control also does not lead to the appearance of the record added in the list.

    Hello

    Re-run the iterator, which depends on the list of selectOneChoice. You can do so after completing the update. The reason why you don't see a change in your current implementation is that you do not change the collection of the iterator that fills the list

  • How to refresh the playlist on Android app

    There is a setting in iTunes/Windows to update the library to the cloud, it sends recent changes, but how do update you the library on the Android app so it pulls down the updates pending in the cloud? I saw him run updates from time to time, but it seems to do it randomly.

    Android app 0.9.9 version (245)

    LG V10 performer Marshmallow 6.0

    I noticed most sync of things more in a few minutes, but things like play counts can take about 24 hours to synchronize with devices.

    Also in the music of Apple on Android, when you're in the high level view of playlists you can drag and pull down to refresh.
