问题描述
我创建自己的自定义弹出窗口，以现在我想添加一个EditField中，似乎一切都很好，但问题是，我不能写在编辑栏任何
类sveetIt扩展PopupScreen实现FieldChangeListener，DialogClosedListener { 哈希表pitemData;
ButtonField字段sveetNowlabelField;
ButtonField字段sveetLaterlabelField;

超级（新MyCustimGridFieldManager（））;
messageLabelField的LabelField =新的LabelField（请输入您的Sveet消息：Field.FIELD_HCENTER）{
保护无效漆（图形图像）{
graphics.setColor（Color.YELLOWGREEN）;
super.paint（图形）;
}
};
EditField中sveetTexteditField =新EditField中（NULL，Sveet消息，50，EditField.FIELD_HCENTER
| EditField.FIELD_VCENTER
| EditField.NON_SPELLCHECKABLE | EditField.NO_NEWLINE）;
VerticalFieldManager buttonVFManager =新VerticalFieldManager（VerticalFieldManager.FIELD_HCENTER）;
HorizontalFieldManager hfManager =新HorizontalFieldManager（）;
sveetNowlabelField =新ButtonField字段（现在Sveet）;
sveetLaterlabelField =新ButtonField字段（Sveet后来）;
sveetNowlabelField.setChangeListener（本）;
sveetLaterlabelField.setChangeListener（本）;
加（messageLabelField）;
加（sveetTexteditField）;
hfManager.add（sveetNowlabelField）;
hfManager.add（sveetLaterlabelField）;
buttonVFManager.add（hfManager）;
加（buttonVFManager）;
}

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);
}
}
