Not able to align images and Titles horizontally.

Hii,

i have created array of Images and Array of Labels to show in one image and one Title in one line horizontally.but i am getting all my images and Title in a single horizontalManager.i am not understanding how to align them now so that i can see One Image and one Title at each line in a list.this is my code snippet.

hr1 = new HorizontalFieldManager(HORIZONTAL_SCROLL|HORIZONTAL_SCROLLBAR){
				protected void onFocus(int direction) {
    		        invalidate();
    		        super.onFocus(direction);
    		    }

   		    protected void onUnfocus() {
    		        invalidate();
    		        super.onUnfocus();
    		    }

    		    public void paint(Graphics graphics) {
    		        if (isFocus()) {
   		        	    graphics.setBackgroundColor(Color.WHITE);
   		                graphics.clear();
    		        }
   		        super.paint(graphics);
    		    }
			};

	System.out.println("after arg++++++++++");
		                                                  for(int j = 0; j< ResponseHandler_Review.vectrImgUrl.size(); j++){
		            	arg = new String[ResponseHandler_Review.vectrImgUrl.size()];
		            	System.out.println("arg values......... = " +arg);
		           	 arg[j] = String.valueOf(ResponseHandler_Review.vectrImgUrl.elementAt(j));
		           	 System.out.println("Array of arg "+j+" = " +arg[j]);
		           	 bit = new Bitmap[ResponseHandler_Review.vectrImgUrl.size()];
			            scaleBit = new Bitmap[ResponseHandler_Review.vectrImgUrl.size()];
			            System.out.println("after bit array+++++++ = " +scaleBit.length);
                          
		           	 System.out.println("Vector element is "+j+" = "+arg[j]);
					 bit[j] = response.getImage(arg[j]);
					 
					scaleBit[j] = new Bitmap(162, 122);
					bit[j].scaleInto(scaleBit[j], Bitmap.FILTER_LANCZOS);
					hr1.add(new BitmapField(scaleBit[j]));
					System.out.println("vectrImgUrl size =  " + ResponseHandler_Review.vectrImgUrl.size());
		            }

			for(int i=0;i<ResponseHandler_Review.vectrTitle.size();i++){
label[i] = new LabelField(ResponseHandler_Review.vectrTitle.elementAt(i), Field.FIELD_VCENTER|Field.FOCUSABLE)
					{
						public int getPreferredWidth() 
						{
							return Display.getWidth()-150;
						}
						protected boolean navigationClick(int status, int time) {
							fieldChangeNotify(0);

							return true;
							
						}
						
					};			
					label[i].setFont(font);
					label[i].setChangeListener(this);
					label[i].setPadding(5, 5, 0, 5);
					
		             System.out.println("print all the labels++++++++++++"+label[i]);
					
					hr1.add(label[i]);	
					
					

			}
			ver.add(hr1);			
			ver.add(new SeparatorField());
			vertical.add(ver);
			add(vertical);

Re: Not able to align images and Titles horizontally.

try to insert image and label in VerticalFieldManager for each image-label pair, then insert these VerticalFieldManagers in your HorizontalFieldManager

 

but I'm not sure if I understood right what you were trying to say, thoughSmiley Happy

Re: Not able to align images and Titles horizontally.

Have you looked at using another Manager, like TableLayoutManager or GridFieldManager?

 

If these are new to you, search the forum for more information on them.

Re: Not able to align images and Titles horizontally.

Not really.  But using multiple VFMs and HFMs is not particularly efficient, especially with adding and removing Fields and there are quirks with each that might make alignment more difficult. And there is the normal scrolling problem to, when you scrol up form a Field and end up somewhere unexpected. 

 

I would recommend TableLayoutManager as the code is quite useful as an example of a Maanger implementation.
