 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.

1. How do I import to eclipse projects that come with the android source?

I downloaded the sourcecode of the android platform, and when I try to build
the sourcecode of projects, say, packages/apps/AlarmClock
I selected creating an Android project using existing code in Eclipse, but I
encountered the following problem:

Invalid project description.
  /home/eshock/android/workspace/AlarmClock overlaps the location of another
project: 'AlarmClock'

Any suggestions?

2. is* packages used in Android?

android supports* packages
so I took a look at them to see if there are any use.
Then I thought most of them aren't used in android application
as there is a security mechanism already in android.

for example, securitymanager is not installed as default, wonder why
google supports it.
and I don't know where or how to use AccessController and Permission
even more, Allpermission class is supported nevertheless permission
list can't be changed once it is set while installation.

so I want to know whether the classes like above are used or not.
but there are no examples or articles on the web.

can anybody help me with this?
