Created a sign up form using Android Studio.
This application creates 4 TextViews which specify the parameter (i.e Name, Email, etc.)
and 4 EditText widgets that allow the user to input their information. Once the submit
button is clicked, all the getText() method is called for each of the EditText widgets.
If any have an empty string (i.e the user didn't input anything), the ToastMessage is created
asking the user to enter all fields. If all the fields have been filled out, but the passwords
do not match, this will alert the user that the passwords do not match. If the user correctly
filled out all forms properly, the Toast message "Welcome " will display.
