hi In blackberry i have created a horizontal field managar and added some buttons of small size to it to display toolbar at the bottom of the screen.But my problem is there is too much space between the 2 buttons.I have to reduce this space between 2 buttons so that i can manage to place atleast 6 buttons at the bottom of the screen.I am using the BFmsg.setMargin(305,0,0,40) statement. can anyone please help me on this.

以下是我的code：

BFcontacts = new ButtonField("Cnt")
    { 
      protected void paint(Graphics graphics) 
         {
        //Bitmap contactsbitmap = Bitmap.getBitmapResource("contacts.jpg");
             //graphics.drawBitmap(0, 0, contactsbitmap.getWidth(), contactsbitmap.getHeight(), contactsbitmap, 0, 0);
             graphics.setColor(Color.WHITE);
             graphics.drawText("Cnt",0,0);
         }
    };


    BFcontacts.setMargin(305,0,0,10);//vertical pos,0,0,horizontal pos
    HFM.add(BFcontacts);

    BFmsg = new ButtonField("Msgs")
    { 
      protected void paint(Graphics graphics) 
         {
        //Bitmap msgsbitmap = Bitmap.getBitmapResource("messages.jpg");
             //graphics.drawBitmap(0, 0, msgsbitmap.getWidth(), msgsbitmap.getHeight(), msgsbitmap, 0, 0);
             graphics.setColor(Color.WHITE);
             graphics.drawText("Msgs",0,0);
         }
    };


    BFmsg.setMargin(305,0,0,40);//vertical pos,0,0,horizontal pos : original
    HFM.add(BFmsg);

   add(HFM)

在此先感谢

具有u使用自定义的经理试图ü可以将内容根据乌拉圭回合的选择这样的

have u tried using custom manager u can place the contents as per ur choice like this

创建该类的对象，并添加项目

Create object of this class and add items to it

class BottomManager extends Manager
     {
         BottomManager()
         {
             super(Manager.NO_VERTICAL_SCROLL);
         }
         protected void sublayout(int width, int height) 
         {
             Field field = getField(0);
             layoutChild(field,Display.getWidth(), Display.getHeight());
             setPositionChild(field,0,0);

             field = getField(1);
             layoutChild(field,Display.getWidth(), Display.getHeight());
             setPositionChild(field,10+getField(0).getWidth(),0);

             field = getField(2);
             layoutChild(field,Display.getWidth(), Display.getHeight());
             setPositionChild(field,10+getField(1).getWidth(),0);

             field = getField(3);
             layoutChild(field,Display.getWidth(), Display.getHeight());
             setPositionChild(field,getField(2).getWidth()+10,0);

             setExtent(Display.getWidth(), 40);
         }
     }
