How to set events on EditTextPreference dialog like longpress

Spent a lot on working on the preferences settings in android google also couldn't help me at last I could do some experiement and made it work.

Goal : Open the Contacts and fill the phone number in one of the inputs for Preferences.

e.g You want to set the Number only Edit text

public class SettingsFragment extends PreferenceFragment {

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        addPreferencesFromResource(R.xml.preferences_activity);

        

        Preference preference = findPreference("EMERGENCY_PH_NO") ;

        EditTextPreference editTextPreference = (EditTextPreference) preference;

    }

}

now its easy just grab the handle and set the longpress event

All the code is given below

public class SettingsFragment extends PreferenceFragment {

EditText m_emergency_number = null;

final int EMERGENCY_CONTACT_PICK = 1337;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        addPreferencesFromResource(R.xml.preferences_activity);

        

        Preference preference = findPreference("EMERGENCY_PH_NO") ;

        EditTextPreference editTextPreference = (EditTextPreference) preference;

        //TextView TextView = (TextView) editTextPreference.getEditText();

        m_emergency_number = (EditText) editTextPreference.getEditText();    

        m_emergency_number.setOnLongClickListener(new OnLongClickListener() {

@Override

public boolean onLongClick(View v) {

// TODO Auto-generated method stub

openContact(EMERGENCY_CONTACT_PICK);

return true;

}

});

    }    

    

    void openContact(int who)

{

Intent intent = new Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);

intent.setType(Phone.CONTENT_TYPE); // Show user only contacts w/ phone numbers

        startActivityForResult(intent, who);

}

    

    @Override

    public void onActivityResult(int requestCode, int resultCode, Intent aData) {

    // TODO Auto-generated method stub

    if (resultCode == Activity.RESULT_OK) 

    {

       Uri contactUri = aData.getData();

       //Intent intent = new Intent(Intent.ACTION_GET_CONTENT,contactData);

           //startActivityForResult(intent, 1336);

       String[] projection = {Phone.NUMBER};

       

       Cursor cursor = getActivity().getContentResolver().query(contactUri, projection, null, null, null);

            cursor.moveToFirst();

               // Retrieve the phone number from the NUMBER column

               int column = cursor.getColumnIndex(Phone.NUMBER);

               String number = cursor.getString(column);

               if(EMERGENCY_CONTACT_PICK == requestCode)

               {

                m_emergency_number.setText(number);

               }

    }

    }

}
