title: How to retrieve multiple values in Firebase Database?
body: <p>I'm a beginner in Firebase and I'm still learning so I made an login-signup app and I'm adding more functionality like Saving Data(which is done) and now I can't figure out how I will retrieve multiple data with different User UID's</p>
  
  <p>Heres a screenshot of my database

  <p>I would like to retrieve all of the data here in 3 different edittext in the layout basically when a person logs in, the program should read database and check if there is data in there then it will get data from the database otherwise it will show a toast saying that No data saved to retrieve... I would be really thankfull if anyone helps me out with this...</p>
