如何创建Blackberry Custom TAb栏

Question

我是黑莓开发的新手。我希望在我的项目中屏幕底部有一个自定义标签栏，用于黑莓应用程序，与下面给出的图像相同。我尝试了黑莓手机提供的示例代码。

但是现在我想使用自定义用户界面。我在Google上搜索过它，并且没有获得有关自定义字段的任何有效信息。请告诉我如何在黑莓手机上做到这一点。

以前是否有人这样做过？

请回复任何链接/代码/摘要。

Answer 1

试试这段代码 -

EncodedImage e2 = EncodedImage.getEncodedImageResource("map.png");
EncodedImage e3 = EncodedImage.getEncodedImageResource("members.png");
EncodedImage e4 = EncodedImage.getEncodedImageResource("message.png");
EncodedImage e5 = EncodedImage.getEncodedImageResource("settings.png");
EncodedImage e6 = EncodedImage.getEncodedImageResource("logout.png");

EyelidFieldManager manager = new EyelidFieldManager();
HorizontalFieldManager buttonPanel = new HorizontalFieldManager(Field.FIELD_TOP | Field.USE_ALL_WIDTH);

  VerticalFieldManager vfm=new VerticalFieldManager();
  vfm.add(new BitmapField(e2.getBitmap(),FOCUSABLE){
     protected boolean navigationClick(int status, int time){

        Dialog.alert("MAP");
        return true;
       }

  });
  buttonPanel.add(vfm);
  buttonPanel.add(new LabelField("  "));

  VerticalFieldManager vfm1=new VerticalFieldManager();
  vfm1.add(new BitmapField(e3.getBitmap(),FOCUSABLE){
     protected boolean navigationClick(int status, int time){

        Dialog.alert("Members");
        return true;
       }

  });
  buttonPanel.add(vfm1);

  VerticalFieldManager vfm2=new VerticalFieldManager();
  vfm2.add(new BitmapField(e4.getBitmap(),FOCUSABLE){
     protected boolean navigationClick(int status, int time){

        Dialog.alert("Message");
        return true;
       }

  });
  buttonPanel.add(vfm2);

  VerticalFieldManager vfm3=new VerticalFieldManager();
  vfm3.add(new BitmapField(e5.getBitmap(),FOCUSABLE){
     protected boolean navigationClick(int status, int time){

        Dialog.alert("Settings");
        return true;
       }

  });
  buttonPanel.add(vfm3);

  VerticalFieldManager vfm4=new VerticalFieldManager();
  vfm4.add(new BitmapField(e6.getBitmap(),FOCUSABLE){
     protected boolean navigationClick(int status, int time){

        Dialog.alert("Logout");
        return true;
       }

  });
  buttonPanel.add(vfm4);

  manager.add(buttonPanel);

  setTitle(manager);

你忘记了什么。在构造函数中创建新类，推送屏幕扩展主屏幕的另一个类

示例：

public class MyApp extends UiApplication{
public MyApp(){        
    pushScreen(new LoadingScreen());
}    }
