解决方案

尝试添加 Field.EDITABLE 你的风格的EditField中。

I have created my own custom popup screen to which now I am trying to add a editfield , everything seems to be fine but the problem is that I am not able to write anything in the edit field

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); } }

解决方案

Try adding Field.EDITABLE to your style for the EditField.
