 Hi all group members,

I am facing a problem any one can help me regarding this.

I have an  EditText and a list of contacts. I want to search a
contacts on maching with characters entered in EditText field. In my
activity I have implemented  "OnKeyListener" .

and in onCreat (){
  searchField = (EditText)findViewById(;
 and i have also implemented the method like this

public boolean onKey(View v, int keyCode, KeyEvent event) {

//Here i am getting text from my search field and comparing with
contacts and updating contacts list

When i pressed keys like (abc ---> xyz or 0 -->9 or any key) from my
computer key board or
keyboard which is displaying on right side of the emulator my code is
working fine. Currently I am using HTC Magic Emulator and Device also.

*******Its workin fine for me******
But now move to issue-->>>

when i touch EditText field  a software keyboard launched and when i
pressed any key from my screen keyboard
its not giving me the events in onKey() method in other words its not
calling onKey(){} method. but this method is called on specific keys
like (0 to 9 and Delete key).

I have also implement "keyListener" interface and its 4 to 5 methods
like keyUp(), keyDown(),etc  but when i implement "keyListener"
softkeyboard is not launching on touching my EditText field.

Any useful solution would be highly appriciated.
Thanks in advance.

 I find the same problem of it.
Finally, I found EditText.addTextChangedListener(new TextWatcher(){})
will let get the event.
Good luck.

 Hi Banny, Hassan,

Even i faced the same problem and added on text change listener
through text watcher. But in this case I am not able to catch the
events of keys like caps, shift, changing from abc to 123.
Any idea on this how to solve?

Thanks and Regards,

 here are no events for those things.  They are just internal state changes
in the IME. Some IMEs may not even have such changes -- for example a
handwriting one may allow you to write letters and numbers in the same area.
