ポップアップ画面に編集フィールドを追加する

Question

編集フィールドを追加しようとしている独自のカスタムポップアップ画面を作成しましたが、すべて問題はないようですが、編集フィールドに何も書き込めないという問題があります。

class sveetIt extends PopupScreen implements FieldChangeListener, DialogClosedListener { 

    Hashtable pitemData; 
    ButtonField sveetNowlabelField; 
    ButtonField sveetLaterlabelField; 
    WatingScreen watingScreen; 
    long scheduledTime; 
    Dialog updateDialog; 

    public sveetIt() { 
     super(new MyCustimGridFieldManager()); 
      LabelField messageLabelField = new LabelField("Enter your Sveet Message:",Field.FIELD_HCENTER) { 
      protected void paint(Graphics graphics) { 
       graphics.setColor(Color.YELLOWGREEN); 
       super.paint(graphics); 
      } 
     }; 
    EditField sveetTexteditField= new EditField(null, "Sveet Message", 50, EditField.FIELD_HCENTER 
        | EditField.FIELD_VCENTER 
        | EditField.NON_SPELLCHECKABLE | EditField.NO_NEWLINE); 
     VerticalFieldManager buttonVFManager = new VerticalFieldManager(VerticalFieldManager.FIELD_HCENTER); 
     HorizontalFieldManager hfManager = new HorizontalFieldManager(); 
     sveetNowlabelField = new ButtonField("Sveet Now"); 
     sveetLaterlabelField = new ButtonField("Sveet Later"); 
     sveetNowlabelField.setChangeListener(this); 
     sveetLaterlabelField.setChangeListener(this); 
     add(messageLabelField); 
     add(sveetTexteditField); 
     hfManager.add(sveetNowlabelField); 
     hfManager.add(sveetLaterlabelField); 
     buttonVFManager.add(hfManager); 
     add(buttonVFManager); 
    } 
    public boolean isEditable() { 
     return true; 
    } 

    protected boolean keyChar(char c, int status, int time) { 
     boolean retVal = false; 

     if (c == Characters.ESCAPE) { 
      Ui.getUiEngine().popScreen(this); 
      retVal = super.keyChar(c, status, time); 

     } 
     return retVal; 
    } 

    public void fieldChanged(Field field, int context) { 
     if (sveetNowlabelField == field) {   

      //Here directly starts uploading file 
      beginUpload(); 
     } else if (sveetLaterlabelField == field) { 
      // first picks up time when to upload 
      scheduledTime = getScheduleTime(); 
      if(scheduledTime!=1L) { 
       //now begins uploading file 
       beginUpload(); 
      } 
    }} 

    class SubscribingThread extends StoppableThread { 
     int network = 50; 

     public void run() { 

     } 
    } 

    public void beginUpload() { 
     try { 
      watingScreen = new WatingScreen("Uploading Sveet..."); 
      /* 
      * UiApplication.getUiApplication().invokeAndWait(new Runnable() { 
      * public void run() { Ui.getUiEngine().pushScreen(watingScreen); } 
      * }); 
      */ 
      BaseScreen.pushScreen(watingScreen); 
      Thread thread = new Thread(new Runnable() { 
       public void run() { 
        uploadToServer(); 
       } 
      }); 
      thread.start(); 
      // uploadToServer(); 
     } catch (Exception e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } finally { 

     } 
    } 

    private long getScheduleTime() { 
     scheduledTime = 0; 
     final DateTimePicker datePick = DateTimePicker.createInstance(); 
     UiApplication.getUiApplication().invokeAndWait(new Runnable() { 
      public void run() { 
       // TODO Auto-generated method stub 
       Calendar currentCalendar = datePick.getDateTime(); 
       datePick.setMinimumDate(currentCalendar); 
       datePick.doModal(); 
       Calendar cal = datePick.getDateTime(); 
       if (cal.after(currentCalendar)) { 
        Date date = cal.getTime(); 
        Dialog.alert("You selected " + date.toString()); 
        scheduledTime = date.getTime(); 
       } else { 
        Dialog.alert("Invalid date selection"); 
        scheduledTime = 1L; 
       } 
      } 
     }); 

     System.out.println("date in MilliSeconds is:" + scheduledTime); 
     return scheduledTime; 
    } 

public void uploadToServer() { 

    } public void dialogClosed(Dialog arg0, int arg1) { 

    } 
} 

class MyCustimGridFieldManager extends VerticalFieldManager { 

    public MyCustimGridFieldManager() { 
     super(VERTICAL_SCROLL | USE_ALL_WIDTH | FIELD_HCENTER); 
    } 

    protected void paint(Graphics gr) { 
     super.paint(gr); 
    } 

} 

Answer 1

はこれを試してみてください。

protected boolean keyChar(char c, int status, int time) { 


    if (c == Characters.ESCAPE) { 
     Ui.getUiEngine().popScreen(this);   

    } 

    return super.keyChar(c, status, time); 
} 

Answer 2

はEditFieldのために、あなたのスタイルにField.EDITABLEを追加してみてください。
