Vector to ListField

• ListField (s) nested in VerticalFieldManager-> SWIPE/SCROLL with HorizontalFieldManager

  I have 2 ListField objects. Each within its own VerticalFieldManager object. 2 VFMs are inside a HorizontalFieldManager object. I am trying to allow the user to BLOW/scrolling of one ListField to another (LEFT/RIGHT). I did not have the TouchEvent portion this again (I guess I'll have to put in place something there).

  Here's what I have so far... However, only the first ListField shows with data (random numbers right now). The other is empty. I also want to allow the user to select individual lines in each ListField

  All the suggestions/help is appreciated.

  See you soon,.

  public final class MyScreen extends MainScreen {
  
      public MyScreen() {
          super(MyScreen.NO_VERTICAL_SCROLL);
          Random rand = new Random();
          HorizontalFieldManager hm = new HorizontalFieldManager(HorizontalFieldManager.HORIZONTAL_SCROLL);

                  g.drawText(text, 5, y, 0, w);
              }

              }
  
              public int indexOfList(ListField list, String p, int s) {
                  return _elements.indexOf(p, s);
              }
  
              public int getPreferredWidth(ListField list) {
                  return Display.getWidth();
              }
          }
  
          protected void sublayout(int width, int height) {
              super.sublayout(width, height);
  
              setExtent(width, height);
          }
  
          private void updateList() {
              _lf.setSize(_elements.size());
          }
  
      }
  }
  

  The two lists show up... However, the halves just in the same HM. My goal is to have everyone take full screen (visible at the time) only... then the user has to SWIPE (from EAST to WEST) to see the list of the other.

  So I changed the following line

  super.sublayout(Display.getWidth(), height);
  

  Thanks Peter

• Implementing custom listener for ListField

  I'm trying to implement a listener for a custom field I created that would launch a new screen when you click on the field. However, nothing happens when I click on the custom field. I use BlackBerry Java plug-in for Eclipse, JDK 1.3 and JRE 6.0. All my code is attached. MyScreen.java contains the code where I'm trying to implement a function fieldChanged.

          // RichTextField is focusable by default. Here we provide a style
          // parameter to make the field non-focusable.
          add(new RichTextField("This is the speed bump screen!", Field.NON_FOCUSABLE));
      }
  
  }
  

  In addition, there is nothing in the ListField that will actually generate an event.

  Here is a simple extension to the ListField which will make "clickable".  In your FieldChangeListener you can use getSelectedindex to determine which line has the focus.

  Please ask if this isn't clear:

  public class ClickableListField extends ListField {
  
      public ClickableListField(int numberOfRows) {
          super(numberOfRows);
      }
  
      protected boolean navigationClick(int status, int time) {
          this.fieldChangeNotify(2);
          return true;
      }
  
      protected boolean touchEvent(TouchEvent message) {
          int x = message.getX( 1 );
          int y = message.getY( 1 );
          if( x < 0 || y < 0 || x > getExtent().width || y > getExtent().height ) {
                  // Outside the field
                  return false;
          }
          // If click, process Field changed
          if ( message.getEvent() == TouchEvent.CLICK ) {
              this.fieldChangeNotify(2);
              return true;
          }
          return super.touchEvent(message);
      }
  
  }
  

• Unable to fill ListView with vector

  I'm using a sample I got on the internet to create a listfield

  that contains an image and the data contained in a vector.

  Data are obtained from a JSON array that is created from a script php accessing a mysql database.

  The problem is that the listfield poster not only any content, even if there are items in the table.

  This is the code I use to get the JSON array data :

  JSONArray items_array=job.getJSONArray("items");
                      for(int i=0;i
  The code for the ListFieldCallback:
  class MyListModel implements ListFieldCallback
         {
  
             private ListField _view;
             private int _defaultRowHeight=32;
             private int _defaultRowWidth=_defaultRowHeight;
             private int _txtImagePadding=5;
             private Bitmap _bitmap;
              private Vector _data;
             public MyListModel(ListField list,Vector data)
                   {
                       _view=new ListField();
                      _data=new Vector();
                       _data=MyScreen.data_vec;
                       _view=list;
                       list.setCallback(this);
                      // _view.setSize(_data.size());
                       _view.setRowHeight(_defaultRowHeight);
                       _bitmap=null;
  
                       //list.setSize(_data.size());                     
  
                       }
  
             public void drawListRow(ListField list,Graphics g,int index,int y,int w)
             {
                 Items itemToDraw=(Items)this.get(list,index);
                 String name=itemToDraw.getName();
                 g.drawText(name,_defaultRowWidth+_txtImagePadding,y,DrawStyle.LEADING|DrawStyle.ELLIPSIS,w-_defaultRowWidth-_txtImagePadding);
  
                 g.drawBitmap(0,y,_bitmap.getWidth(),_bitmap.getHeight(),_bitmap,0,0);
  
                 }
  
  The code for the method of success which must now fill listview:
  public void success(final Vector listboys)
          { 
  
            UiApplication.getApplication().invokeLater(new Runnable()
            {public void run()
            {
               data_vec=new Vector();
            data_vec=listboys;
            Items it1=(Items)data_vec.elementAt(0);
            error("Vector Main Screen " +it1.getName());
                               final MyListField myListView=new MyListField();
        final  MyListModel myListModel=new MyListModel(myListView,data_vec);
       myListView.addToContextMenu(myListModel.getAddMenuItem(0,0));
      myListView.addToContextMenu(myListModel.getRemoveMenuItem(0,0));
      myListView.addToContextMenu(myListModel.getModifyMenuItem(0,0));
      myListView.addToContextMenu(myListModel.getEraseMenuItem(0,0));
  
      {
          Manager vfm=getMainManager();
          vfm.add(myListView);
          vfm.add(new SeparatorField(SeparatorField.LINE_HORIZONTAL));
          setTitle("List Demo Title");
  
          }
  
  The listview is always empty. I don't see where data is passed to display. Whenever I call:
  list.setSize(_data.size());
  
  I always get a null pointer exception. How can I get the listview to display the data contained in the vector itemsholder. Thank you
  			 
  using images in a listfield is not difficult, to improve that worked for you.
  You can use drawBitmap to draw the image in the listfield.

  Thanks in advance...

  Oky I solved the problem...

  using the...

  {if (g.isDrawingStyleSet (Graphics.DRAWSTYLE_FOCUS))}

  change the accent color
  g.setBackgroundColor (0xDCDCDC);
  g.Clear ();
  draw text
  g.setFont (Resize.getSecondFont ());
  g.setColor (Color.BLACK);
  g.drawText (item.toString (), 20, y, DrawStyle.ELLIPSIS |) DrawStyle.HCENTER);
  }

  inside the drawListRow...

  Thank you all...

          }
      };
  }
  

  and my problem is when I click on the button that show me ListField and context menu... and I do not know how to disable the context menu open...

  second problem is:
  in this list I generated 4 rows with unique name

  for(int in = 0; in < 4; in++)
  {
  Name = "Name" + in;
  
  String listTitle = Name;
  String listDesc = "Description: ";
  String listDesc2 = "Desc: ";
  
  info.addElement(new ListRander(displayPicture, listTitle, listDesc, listDesc2));
  }
  

  and I want to click on line, so I have to show for this specific line name...

  myListView = new CustomListField(info)
  {
      protected boolean trackwheelClick (int status, int time)
      {
         Dialog.alert(" Selected :" + Name);
         return super.trackwheelClick(status, time);
      }
  };
  

  and I have problem of course that shows me all name lines generated only modified (for example name03).

  can you help me please?

  Thank you

  Stepan

  (1) change

  btnSearch = new ButtonField ("Search");

  TO

  btnSearch = new ButtonField ("Search", ButtonField.CONSUME_CLICK);

  (2) I would have thought that you want something like

  protected boolean trackwheelClick (int status, int time)
  {
  ListRander selectedLine = (ListRander0 (this.getSekectedIndex ()) info.elementAt;

  String name = selectedLine.getName ();

  Dialog.Alert ("Selected:" + name);
  Return super.trackwheelClick (status, time);
  }

• Download the text of ListField

  After hours of sifting through forums and Googling I hope someone can help me.

  I have a ListField filled with a vector of strings. The strings are the urls that the user can select to load a page. I'm trying to get the selected url, but when I click on one has no effect, it always loads the first element.

  It doesn't seem to be any code that loads the URL here.  It seems unlikely that this bug is in this code.

  When I did click ListFields I use

  . getSelectedIndex()

  to see how input from the user has selected in fact.

• Sort of a listfield

  Hello..

  I display a listfield of names in the address book...

  I use vector for holding data from address book...

  Vector objects contains the following data...

  Title

  First name

  Family name

  Contact No.

  I'm adding contacts to the listfield. but I want that they sorted according to the displayname property that contains the title, first name and family name...

  Please suggest...

  Thank you

  He provided no method of sorting a ListField.

  You can sort the vector yourself or use one of the classes that can be sorted.

  Generally, I sort myself, that you can then give your users the ability to change the type - for example, you might want to sort your vector by the first or last name.

  When sorting of the channels, I recommend that the String.compareTo (.) or StringUtilities.compareToIgnoreCase (.)

  as I think that changing your code and then answer me

• ListField line personalized with text and images

  Hello

  I use the example of complex files provided at this URL as a basis for my application. I want to do is get data feed from a Web site and post it in a ListField. Each row in the field has a picture and associated text.

  I made the following changes in my implementation of the application in the example

  1. create a normal ListField instead of a subclass of ListField

  2 getting data from the stream and fill a vector with the necessary information

  3. implementation of the ListFieldCallback.

  In the drawListRow of the callback method, I create a TableRowManager object and pass the data for that particular line. Using these data, I create fields and adding them to the TableRowManager. Then by the drawRow of the TableRowManager method, I call sublayout() and specifying the x, y, width, height for each field in the TableRowManager.

  Now, when you debug the application, I see that the drawListRow method is called whenever I move around the list or when the ListField is first added to its parent. But none of the fields or lines are displayed.

  DrawRow even is called whenever drawListRow. But the lines are never displayed. I just get a white screen. Tried to remove all fields and keep a single LabelField, but even that is not displayed.

  Here's the code, if this is useful

  Class TableRowManager

  private class TableRowManager extends Manager
      {
          int _index;
  
          TableRowManager(String myTxt, String msg, String imageUrl, int index)
          {
              super(0);
              BitmapField imgField = new WebBitmapField(imageUrl);
              add(imgField);
  
              LabelField personLabel = new LabelField(myTxt, DrawStyle.ELLIPSIS);

  the callback method drawListRow

  public void drawListRow(ListField list, Graphics g, int index, int y, int w)
      {
          String text = (String)listElements.elementAt(index);
          String str1 = text.substring(0,text.indexOf("-"));
          String str2 = text.substring(text.indexOf("-")+2);
          String imageName = image[index];
         String url = "http://myURL/"+imageName;
         TableRowManager rowManager = new TableRowManager(str1,str2,url, index);
          rowManager.drawRow(g, 0, y, w, list.getRowHeight());
      }
  

  Can someone please help me with this. The format of what I'm looking for is something like this

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

  | image |  LabelField1

  |           |  LabelField2

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

  Thank you.

  What I usually do with the listField is myself to draw the bitmap and text, something like the following:

  ' public void drawListRow (list ListField, Graphics g, int index, int y, int w)
  {
  String text = (String) listElements.elementAt (index);
  String str1 = text.substring (0, text.indexOf("-"));
  String str2 = text.substring (text.indexOf("-") + 2);
  String imageName = image [index];

  Z.i. bitmap = / * get the bitmap * / (better preparation before coming here, for performance)

  int xPos = LEFT_OFFSET;
  int ypos = TOP_OFFSET + y;
  int w = bitm.getWidth ();
  int h = bitm.getHeight ();
  fontHeight int = this.getFont () .getHeight ();

  g.drawBitmap (PosX, Posy, w, h, z.i., 0, 0);

  PosX = w + SOME_OFFSET

  graphics.drawText (str1, xpos, ypos);
  YPos += fontHeight;

  graphics.drawText (str2, xpos, ypos);

  }

  It worked for me all the time.

  Of course, I don't want to say that do you it this way, but I'm just give another alternative that works.

• The remote XML parsing and ListField implementation

  I use Blackberry 9800 Simulator, JRE 6.0.0

  Hello

  I have a remote XML I want to analyze, but for some reason, my ListField shows only 1 row. I tried debugging and saw the number of attributes my vector, which is significantly greater than 1.

  Here is my code: http://pastebin.com/zRDW2xfn

  I'm doing something wrong?

  In addition, in the ListFieldCallback, the drawListRow index does not increment...

  Hey there,

  I found the problem, if you print the exception, you will see what is wrong. Basically, you dodnt have access to the UI within this thread.

  I changed the class connectionthread for you below.

  private class Connection extends Thread{
  
          public String title;
          public int i=0;
  
          public Connection(){
              super();
          }
  
          public void run(){
              // define variables later used for parsing
              Document doc;
              StreamConnection conn;
              try{
                  conn = (StreamConnection)Connector.open("http://tpae.me/events.xml;deviceside=true");
                  DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
                  DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
                  docBuilder.isValidating();
                  doc = docBuilder.parse(conn.openInputStream());
                  doc.getDocumentElement().normalize();
                  NodeList list = doc.getElementsByTagName("Event");
  
                  for (i=0;i
  Note: the fix is not optimal, but his show you how it should be done.
  Please let me know if you still have problems or questions.
  		   

• Weird behavior of ListField on touch devices

  Hello!

  I have a custom ListField, who has a weird behavoid on palpable devices like the torch and storm. I try to move it with my fingers but it does weird things. If it happened to someone else?

  My code is:

  As far as I KNOW, the mechanism of scrolling, you talk about work out of the box with a standard ListField.  Have you tried to use a ListField standard to see if you can make it work?
  I suspect that your code passes very slowly, because of the significant workload in the painting of each line.  I think that if you've tried this code on a trackpad device, you would have problems scrolling too, have you actually tried on another device?
  With regard to obtaining click events working on a ListField, you can find the following useful code.  Using this, you can add a FieldChangeListener to the ListField and it will go through standard fieldChanged code when it is selected.
  /**
  * Simple extension of the ListField designed to
  FieldChangeListener disk on "click here".
  *
  To examine the methods of field substituted here for more information.
  */
  Import net.rim.device.api.ui.component.ListField;
  Import net.rim.device.api.ui.TouchEvent;
  SerializableAttribute public class ClickableListField extends {ListField
  public ClickableListField (int numberOfRows) {}
  Super (numberOfRows);
  }
  protected boolean navigationClick (int status, int time) {}
  this.fieldChangeNotify (2);
  Returns true;

  If (message.getEvent () == TouchEvent.CLICK) {}

• How to udpate listfield lines specially

  This app, I have developed is a reader of history. It has a screen which contained a listfield. I hope that I can update the listfield.

  Maybe just change a line of the listfield with special index.

  But I do not know how to implement it.

  Now I just use the method as follows:

  for (int i = 0; i)<>

  {

  ListField.Delete (0);

  listfieldcallback. Remove (0);

  }

  for (int i = 0; i = Vecotr.Size (); i ++)

  {

  ListField.Insert (i);

  listfieldcallback. Insert (Object, i);

  }

  then call this Manager listfield: listfieldmanager.invalidate ();

  I think that there should be better elsewhere update lines specially listfield

  In your ListFieldCall back when you insert the new element, he might just added to the vector, just give a look at the methods you use.  You may need to use Vector.insertElementAt ()...

• Java Blackberry ListField

  I developed an Rss Application for Blackberry (java) and I've posted titles successfully (list of Radio stations must play online) from code Rss File.i already developed to play these list of Radio channels, but my requirement is to play the first channel (the first list) when my list initially displayed (list of strings) , can someone help me where I can write my logic (the first string of default playback) to run after my displayed immediately channels?
