Can you Please tell me how to set these Value in Registers, then I will create Four Step Of Signup.

Answer 1

There are many way to pass value from one activity to another activity like shared preference, bundle,intent putextra, database.. for a beginner you can use the shared preference.. i hope this will help you..

1.Following tutorial may help you:

Simple example for shared preference with source code

Answer 2

Option 1: Just pass the data

if you want to just pass data from one activity to another than you can do like this

startActivity(new Intent(Context,Activity_name.class).putExtra("Key",Value));

and get in next Activity like

Intent intent = getIntent();
variable = = intent.getXXXExtra("Key");

Option 2 Save data in to SharedPreferences

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putXXX("Key", Value);
editor.commit();

and get data from it

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
Variable = getResources().getInteger("Key");

Answer 3

You can do this using one of the following methods

1. Use Shared Preferences to save your data and you can access it from anywhere in the application (recommended).
2. If you have more data to be stored, I recommend using database.
3. You can pass the values from one activity to another using intent.putExtra() method. But you will have to do this for all new Activities
4. Another simple method is to make your variables public static and access the data using static reference from any where in your project. (not recommended).

Hope this will help you. :)
