Java Development

I want to create a toolbar like the one we see in twitter application. 

I have created one like this. Have used custom manager,  to distribute image evenly the whole length

Manager Class is as following

Manager customManager = new Manager(0)
{
protected void sublayout(int width, int height) {
setPositionChild(
getField(0), 
0, 
0);
layoutChild(
getField(0), 
getField(0).getPreferredWidth(), 
getField(0).getPreferredHeight());
setPositionChild(
getField(1), 
Graphics.getScreenWidth()/2 - getField(1).getPreferredWidth()/2, 
0);
layoutChild(
getField(1), 
getField(1).getPreferredWidth(), 
getField(1).getPreferredHeight());
setPositionChild(
getField(2), 
Graphics.getScreenWidth() - getField(2).getPreferredWidth(), 
0);
layoutChild(
getField(2), 
getField(2).getPreferredWidth(), 
getField(2).getPreferredHeight());
setExtent(width, 30);
} 
};

I add images in the manager as following

DesignToolBar(customManager);

	private void DesignToolBar(Manager hfm) {
         
		Bitmap imgInbox = Bitmap.getBitmapResource("inbox-32.png");
		fldInbox = new BitmapField(imgInbox){
			protected boolean navigationClick(int status, int time) {
				Dialog.alert("Inbox"); 
				// KeypadListener.STATUS_FOUR_WAY or KeypadListener.STATUS_TRACKWHEEL
				return true; //this says you handled the event
			}
		};
		//fldInbox.setChangeListener(customListener);
		
		Bitmap imgOutbox = Bitmap.getBitmapResource("outbox-32.png");
		fldOutbox = new BitmapField(imgOutbox){
			protected boolean navigationClick(int status, int time) {
				Dialog.alert("Outbox");  
				// KeypadListener.STATUS_FOUR_WAY or KeypadListener.STATUS_TRACKWHEEL
				return true; //this says you handled the event
			}
		};
		//fldOutbox.setChangeListener(customListener);
		
		Bitmap imgSearch = Bitmap.getBitmapResource("search-32.png");
		search = new BitmapField(imgSearch){
			protected boolean navigationClick(int status, int time) {
				Dialog.alert("Search"); 
				return true; //this says you handled the event
			}
		};
		//search.setChangeListener(customListener);
		
		hfm.add(fldInbox);
		hfm.add(fldOutbox);
		hfm.add(search);
		hfm
		.setBackground(BackgroundFactory.createLinearGradientBackground(Color.WHITESMOKE,Color.WHITESMOKE,Color.DARKGRAY,Color.DARKGRAY));
		
	}

The images display fine. But when I click them nothing happens. Am I missing something ?

Changed the code to following

fldInbox = new BitmapField(imgInbox, Field.FOCUSABLE|Field.HIGHLIGHT_FOCUS){
			protected boolean navigationClick(int status, int time) {
				Dialog.alert("Inbox"); 
				// KeypadListener.STATUS_FOUR_WAY or KeypadListener.STATUS_TRACKWHEEL
				return true; //this says you handled the event
			}
		};

Even then, Alert is not displaying !
