我很郁闷...IndexForm ,MainList 这两个界面都正常的,但到了第三级界面
PersonList,AddForm的按钮就不行了.
下面是RMSMain的代码.
package personList;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
public class RMSMain extends MIDlet implements CommandListener{
IndexForm indexform;
MainList mainlist;
PersonList personlist;
AddForm addform;
DetailForm detailform;
PersonAction personaction;
Display display;
public RMSMain() {
indexform = new IndexForm( "电话簿,欢迎您 ");
mainlist = new MainList();
personlist = new PersonList();
addform = new AddForm( "添加联系人 ");
detailform = new DetailForm( "联系人信息 ");
personaction = new PersonAction();
indexform.setCommandListener(this);
mainlist.setCommandListener(this);
personlist.setCommandListener(this);
addform.setCommandListener(this);
detailform.setCommandListener(this);
}
protected void destroyApp(boolean b) throws MIDletStateChangeException {
}
protected void pauseApp() {
}
protected void startApp() throws MIDletStateChangeException {
display = Display.getDisplay(this);
display.setCurrent(indexform);
}
public void commandAction(Command c, Displayable d) {
if (c == indexform.cmdOk) {
display.setCurrent(mainlist);
} else if ( d instanceof MainList) {
if ( c == mainlist.cmdOk) {
int i = mainlist.getSelectedIndex();
System.out.print(i);
switch(i) {
case 0:
System.out.println( "0 ");
personlist = personaction.readAll();
display.setCurrent(personlist);
break;
case 1:
System.out.print( "1 ");
display.setCurrent(addform);
break;
case 2:
break;
}
} else if ( c == mainlist.cmdBack) {
display.setCurrent(indexform);
}
} else if (d instanceof PersonList) {
if (c == personlist.cmdOk) {
System.out.print( "personlist.cmdOk ");
int i = personlist.getSelectedIndex();
detailform = detailform.ShowDetailPerson(i, personaction.getVector());
display.setCurrent(detailform);
} else if (c == personlist.cmdBack) {
display.setCurrent(mainlist);
}
} else if (d instanceof AddForm) {
if (c == addform.cmdOk) {
