Java ME-lwuit单选按钮

为ResourceEdit#GUI上的

RadioButton

提供组名（对每个

RadioButton

使用相同的名称）。使用以下方法返回

单选按钮

。所以使用这个方法

public class StateMachine extends StateMachineBase implements ActionListener {
  Resources resources;
 RadioButton Verifi=new RadioButton("Verification") ;
   RadioButton Enroll=new RadioButton("Enrollment");
StateMachineBase cl=new StateMachineBase()
        {};
ButtonGroup bg=new ButtonGroup();
static Form fo,f;
public StateMachine(String resFile) {
        super(resFile);
    }
  StateMachine()
    {

try{
    resources = Resources.open("/NEW AADHAR.res");
}
catch(java.io.IOException err)
{ err.printStackTrace(); }
cl.setHomeForm("Welcome");
 //fo = (Form)cl.startApp(resources,null,true);
fo=Display.getInstance().getCurrent();
f=cl.findWelcome(fo);
Verifi=cl.findVerification(f);
Enroll=cl.findEnrollment(f);
bg.add(Enroll);
bg.add(Verifi);
//f.addCommandListener(this);
Verifi.addActionListener(listener);Enroll.addActionListener(listener);
}
  protected  void initVars() {
    }

public void actionPerformed(ActionEvent ae) {

    throw new UnsupportedOperationException("Not supported yet.");
}       

ActionListener listener=new ActionListener(){
     protected void onWelcome_ButtonAction(Component c, ActionEvent event)
        {
Verifi.addActionListener(listener);
if(Verifi.hasFocus())
    {
    showForm("Login",null);

    }
    else if (Enroll.hasFocus())
    {
    showForm("Authentication",null);

   }
    else
        Dialog.show("INFORMATION","Select","OK","Cancel");

     }

        public void actionPerformed(ActionEvent ae) {
            throw new UnsupportedOperationException("Not supported yet.");
        }

};
}

更新1:

使用此代码从生成的类获取表单

public com.sun.lwuit.RadioButton findRadioButton(Container root) {
   return (com.sun.lwuit.RadioButton)findByName("RadioButton", root);
        //root - Pass the RadioButton added Component.
}

GeneratedClass

-使用您的类。

资源

-使用您的资源编辑

将该表单传递给

findRadioButton（…）


更新2:

您提供了2个名为“验证和注册”的单选按钮。
所以使用下面的代码

GeneratedClass genClass = new GeneratedClass() { };
final Form form = (Form) genClass.startApp(resources, null, true);

并检查ResourceEdit#GUI上的
单选按钮组
名称。并为两个
单选按钮提供相同的名称


更新3:

在
mainMidlet.java
类中调用
StateMachine（）

 GeneratedClass genClass = new GeneratedClass() { };
 Form form = (Form) genClass.startApp(resources, null, true);
 RadioButton rbVerification = genClass.findVerification(form);
 RadioButton rbEnrollment = genClass.findEnrollment(form);

高拉夫：你为什么要感谢这个新话题？如果答案是确定的，则表示开始接受答案。好的，但我对您的StateMachine类中的上述问题感到困惑，您在该类中初始化
注册、验证和bg
？公共类StateMachine扩展StateMachineBase实现ActionListener{Resources Resources；StateMachineBase cl=new StateMachineBase（）{}；RadioButton bgVerification；RadioButton bgEnrollment；ButtonGroup bg=new ButtonGroup（）；；在statemachine类及以上的构造函数库中，Bharath。我明白你的意思。请告诉我必须调用FindAdioButton（）方法或findByName（）方法和根目录中，我必须传递我已添加单选按钮的表单名称？如果您想获得
单选按钮
意味着使用
findRadioButton（）
，并且在哪里添加
单选按钮
？我已在formhey Bharath上添加了我的单选按钮。您在方法最终表单=（表单）中的资源是什么意思genClass.startApp（参考资料，null，true）
public class StateMachine extends StateMachineBase implements ActionListener {

    Resources resources;
    RadioButton Verification;
    RadioButton Enrollment;

    public StateMachine(String resFile) {
        super(resFile);
    }

    /**
     * this method should be used to initialize variables instead of
     * the constructor/class scope to avoid race conditions
     */
    StateMachine() {
    }

    protected void initVars() {
    }

    /**
     * @param c
     * @param event
     */
    public void actionPerformed(ActionEvent ae) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

    protected boolean onWelcomeEXIT() {
        boolean val = super.onWelcomeEXIT();
        return val;
    }

    protected void onWelcome_ButtonAction(Component c, ActionEvent event) {

        super.onSampleRB_RadioButtonAction(c, event);
        Verification = (RadioButton) c;  // initialize here
        if (Verification.hasFocus()) {
           showForm("Login",null);
        } else {
           Dialog.show("INFORMATION", "Please select option", "OK", "Cancel");
        }
    }
