I think it is possible by only overriding paint(..) of the Editfield. May be following steps can achieve the desired behaviour:
Store original text to a local variable.
Generate fake text depending on focus status, original text etc.
Call super.paint(..), it will paint the field with fake text.
Use setText(..) to set original text back.
Draft implementation:
class MyEditField extends EditField {
private final static String INIT_TEXT = "Enter Password";
protected void paint(Graphics graphics) {
String originalText = getText();
String fakeText = originalText;
if (originalText.equalsIgnoreCase("")) {
fakeText = isFocus() ? originalText : INIT_TEXT;
} else {
fakeText = "";
for (int i=0;i<originalText.length();i++) {
fakeText += '*';
}
}
setText(fakeText);
super.paint(graphics);
setText(originalText);
}
}
Above code doesn't paint a border.
We need to set a monochrome font for the problem you have mentioned in comment. Here is a sample code:
MyEditField me = new MyEditField();
try {
Font font = null;
FontFamily fontFamily[] = FontFamily.getFontFamilies();
for (int i=0;i<fontFamily.length; i++) {
if (fontFamily[i].getName().equalsIgnoreCase("Courier New")) {
font = fontFamily[i].getFont(FontFamily.SCALABLE_FONT,
Font.getDefault().getHeight());
me.setFont(font);
break;
}
}
} catch (Exception e) {
}

If I understand you correctly, you need to use a PasswordEditField.
Implement it just like any LabelField, and it will do what you need.
I see you wanted the background text too - I would use drawText() from within the paint() method to draw that. The other answer that shows a full implementation by using EditField is also good.
