Hi amir

Just want to clarify, please correct me if I’m wrong
You want to retrieve user from the server by userName value and then get userPhone value, right?

yes the userName came from string inside the edtitext in my app and i want to ask the server the phone number of that user , i know it could be multiple user name but i want to see the way it can be accomplished

Hi Amir,

You need to search for users in your Users table with a where clause. In a callback you can extract required property for every object from the returned list of Backendless users. It can be done in the following way:

DataQueryBuilder queryBuilder = DataQueryBuilder.create();
queryBuilder.setWhereClause( whereClauseFromEditText );
Backendless.Data.of( BackendlessUser.class ).find( queryBuilder, new AsyncCallback<List<BackendlessUser>>()
{
  @Override
  public void handleResponse( List<BackendlessUser> backendlessUserList )
  {
    backendlessUserList.forEach( backendlessUser -> backendlessUser.getProperty( "phoneNumber" ) );
  }


  @Override
  public void handleFault( BackendlessFault backendlessFault )
  {
    System.out.println("Error: " + backendlessFault.getDetail());
  }
} );

Regards,
Anton
