Answer 1

use this code to pick contact:

 Button button = (Button)findViewById(R.id.pickcontact);

    button.setOnClickListener(new OnClickListener() 
        {
            @Override
            public void onClick(View v) 
            {
                 Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                 startActivityForResult(intent, PICK_CONTACT);
             }
         });



    @Override 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 cNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
           // Toast.makeText(getApplicationContext(), cNumber, Toast.LENGTH_SHORT).show();
            setCn(cNumber);
          }
         }
       }
    }
   }
