Here i will demonstrate you that how to pick a contact no and name from a contact list on click or focus event,

Focus Event:-

     phoneNo.setOnFocusChangeListener(new OnFocusChangeListener()
      {   public void onFocusChange(View v, boolean hasFocus) 
          {
             Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
             startActivityForResult(intent,PICK_CONTACT );//PICK_CONTACT is private static final int, so declare in activity class
       } });

• A FUNCTION TO GET THE CONTACT NAME AND PHONE NO IS :

    public void onActivityResult(int reqCode, int resultCode, Intent data)
     {
       super.onActivityResult(reqCode, resultCode, data);
  
          switch(reqCode){
             case (PICK_CONTACT):
               if (resultCode == Activity.RESULT_OK)
               {
                   Uri contactData = data.getData();
                   Cursor c = managedQuery(contactData, null, null, null, null);
                if (c.moveToFirst()) {
                String id =   
                  c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
  
                String hasPhone =
                c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
  
                if (hasPhone.equalsIgnoreCase("1")) {
               Cursor phones = getContentResolver().query( 
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, 
                            null, null);
                  phones.moveToFirst();
                  String phn_no = phones.getString(phones.getColumnIndex("data1"));
                  String name = c.getString(c.getColumnIndex(StructuredPostal.DISPLAY_NAME));
                 Toast.makeText(this, "contact info : "+ phn_no+"\n"+name, Toast.LENGTH_LONG).show();
  
                }
                  }
               }
          }
