private void BottomLayout() 
    {
        Bitmap topBg = Bitmap.getBitmapResource(ImageName.topbar);
        final Bitmap topBg1 = cmn_fun.resizeBitmap(topBg, SCREEN_WIDTH, topBg.getHeight());
        HorizontalFieldManager hfmbottom = new HorizontalFieldManager(Field.USE_ALL_WIDTH)
        {
            protected void paintBackground(Graphics graphics) 
            {
                graphics.drawBitmap(0,0,SCREEN_WIDTH,topBg1.getHeight(), topBg1,0,0 );             
                super.paint(graphics);
            }
            protected void sublayout(int maxWidth, int maxHeight) {
                // TODO Auto-generated method stub
                super.sublayout(topBg1.getWidth(), topBg1.getHeight());
                setExtent(topBg1.getWidth(), topBg1.getHeight());
            }

        };

        Bitmap imgprv=Bitmap.getBitmapResource(ImageName.btn_prev);
        Bitmap imgprv_sel=Bitmap.getBitmapResource(ImageName.btn_prev_sel);     
        btn_prev=new CustomButtonField(0, "", imgprv_sel, imgprv, Field.FIELD_LEFT);
        hfmbottom.add(btn_prev);

        Bitmap imgnext=Bitmap.getBitmapResource(ImageName.btn_next);
        Bitmap imgnext_sel=Bitmap.getBitmapResource(ImageName.btn_next_sel);        
        btn_next=new CustomButtonField(0, "", imgnext_sel, imgnext, Field.FIELD_RIGHT);
        hfmbottom.add(btn_next);


        setStatus(hfmbottom);

    }

先谢谢了。

推荐答案

我张贴你只在状态栏面板。

I am posting you only the status bar panel.

其实在Horizo​​ntalFieldManager它创造的问题。

Actually in the HorizontalFieldManager it does create problem.

因此​​发现了下面的方式，它是工作。它确实增加了额外的code，但它的工作原理

Therefore found out the following way and it is working. It does add extra code but it works

import net.rim.device.api.system.Bitmap;
import net.rim.device.api.system.Display;
import net.rim.device.api.ui.DrawStyle;
import net.rim.device.api.ui.Graphics;
import net.rim.device.api.ui.Manager;
import net.rim.device.api.ui.component.ButtonField;
import net.rim.device.api.ui.container.GridFieldManager;
import net.rim.device.api.ui.container.HorizontalFieldManager;
import net.rim.device.api.ui.container.MainScreen;
import net.rim.device.api.ui.container.VerticalFieldManager;

class SampleBottomPanelScreen extends MainScreen {

private HorizontalFieldManager title_bar;

private VerticalFieldManager btn1_manager;
private ButtonField btn1;
private VerticalFieldManager btn2_manager;
private ButtonField btn2;
Bitmap bg_image;

public SampleBottomPanelScreen() {

    //bg_image = Bitmap.getBitmapResource("backgroundImage.png");

    btn1_manager = new VerticalFieldManager(VerticalFieldManager.FIELD_LEFT) {

         protected void sublayout(int maxWidth, int maxHeight)
         {
                int displayWidth = Display.getWidth() / 2;
                int displayHeight = Display.getHeight();

                super.sublayout( displayWidth, displayHeight);
                setExtent( displayWidth, displayHeight);
         }  
    };

    btn2_manager = new VerticalFieldManager(VerticalFieldManager.FIELD_RIGHT | VerticalFieldManager.USE_ALL_WIDTH) {

         protected void sublayout(int maxWidth, int maxHeight)
         {
                int displayWidth = Display.getWidth() / 2;
                int displayHeight = Display.getHeight();

                super.sublayout( displayWidth, displayHeight);
                setExtent( displayWidth, displayHeight);
         }  
    };

    title_bar = new HorizontalFieldManager(Manager.USE_ALL_WIDTH){

        public void paint(Graphics graphics) {
            graphics.setBackgroundColor(0x2bb1ff);
            graphics.clear();

            super.paint(graphics);
        }

        protected void sublayout(int maxWidth, int maxHeight)
        {
            int displayWidth = Display.getWidth();
            int displayHeight = Display.getHeight() / 8;

            super.sublayout( displayWidth, displayHeight);
            setExtent( displayWidth, displayHeight);
        }   
    };

    btn1 = new ButtonField("Submit", ButtonField.LEFT | ButtonField.FIELD_LEFT);
    btn2 = new ButtonField("Cancel", ButtonField.RIGHT| ButtonField.FIELD_RIGHT);

    btn1_manager.add(btn1);
    btn2_manager.add(btn2);

    title_bar.add(btn1_manager);
    title_bar.add(btn2_manager);

    this.add(title_bar);
}
 }
