带白色背景的BlackBerry自动完成字段?

bb方法是在您想更改现有字段的样式(例如颜色)时扩展它们,因此下面是我的解决方案:

myauto.java:

package mypackage;

import net.rim.device.api.ui.*;
import net.rim.device.api.ui.component.*;
import net.rim.device.api.ui.container.*;
import net.rim.device.api.ui.decor.*;
import net.rim.device.api.system.*;
import net.rim.device.api.collection.util.*;

public class MyAuto extends UiApplication {
    public static void main(String[] args) {
        MyAuto myAuto = new MyAuto();
        myAuto.enterEventDispatcher();
    }

    public MyAuto () {
        pushScreen(new MyScreen());
    }    
}

class MyScreen extends MainScreen {
    public MyScreen() {
        BasicFilteredList filterList = new BasicFilteredList();
        String[] days = {"Monday","Tuesday","Wednesday",
                        "Thursday","Friday","Saturday","Sunday"};
        filterList.addDataSet(1,days,"days",BasicFilteredList.COMPARISON_IGNORE_CASE);
        Background myBG = BackgroundFactory.createSolidBackground(Color.YELLOW);
        Border myBorder = BorderFactory.createBitmapBorder( 
            new XYEdges( 20, 16, 27, 23 ), 
            Bitmap.getBitmapResource( "bubble_left.png" ) );
        AutoCompleteField autoCompleteField = new AutoCompleteField(filterList);
        autoCompleteField.setBorder(myBorder);
        autoCompleteField.getEditField().setBackground(myBG);
        add(autoCompleteField);
    }
}

这个 bubble_left.png 不是真的需要,我只是为了好玩才添加的:

顺便说一下,在我的模拟器(bb 9800)的背景是白色的默认。
