I have a Basiceditfield with initial text. Following is the code: 

searchField = new EditField("","",1024,EditField.FILTER_DEFAULT|EditField.NO_NEWLINE)
{
protected void onFocus(int direction)
{
setLabel("");
this.invalidate();
};
protected void onUnfocus()
{
setLabel("Search");
this.invalidate();
};
};
searchField.setLabel("Search");

Initialy text in searchfield is"Search". Onfocus its set to "". I type something in searchfield ,suppose  "ab".When focus is removed from searchfield label is set to "Searchab". whereas i want it as "Search". Please help.

in onUnfocus, first clear the text before setting the label.

setText("");

setLabel("Search");

I want following things to be done:
1.When i do not type anything in searchfield and if i focus and unfocus searchfield, then Initially text should be "Search". Onfocus text should be blank. Onunfocus text should be "Search".
2.When i type text in searchfield, and remove focus then text in editfield should be typed text only.
3.After condition 2 ,when i focus editfield and deleted all the text which i have type and remove the focus then text should b set to "Search". And searching should not get start with "Search".
Please help me out.

on focus, use getText, check if it is "Search", setText to ""
on onfocus, use getText, check if it is "", set it to "Search".
on keyChar, use getText, check if is "Search, use setText to "", then return super.

You may try to override paint method as per your need (see sample below). 

protected void paint(Graphics graphics) {
super.paint(graphics);
if (!hasFocus) {
if (editField.getText() == null	|| editField.getText().equals("")
|| editField.getText().trim().length() == 0) {
editField.setText("");
// if EditField is Empty Then it will show initial String
graphics.setColor(Color.GRAY);
int y = (height - editField.getFont().getHeight()) / 2;
graphics.drawText(initial, 10, y + 1);
graphics.setColor(Color.BLACK);
	                                      }
			}

simon hain:
I did the changes as per your suggestion:

searchField = new EditField("","",1024,EditField.FILTER_DEFAULT|EditField.NO_NEWLINE)
{
protected void onFocus(int direction)
{
if(getText() == "Search")
setText("");
this.invalidate();
};
protected void onUnfocus()
{
if(getText() == "")
setText("Search");
this.invalidate();
};
protected boolean keyChar(char key, int status, int time)
{
if(this.getText().equals("Search"))
this.setText("");
return super.keyChar(key, status, time);
}
};
searchField.setText("Search");

I am facing following problems:

a.Unable to set text to "" on focus.

b.Unable to do thing specified in condition 3 as i mentioned above.

c.When i click on searchfield it is not set to "".

OHH my mistake.....condition should be getText().equals("Search")
and not getText() == "Search". Thanx simon. working fine.
