Question

The problem is that I can’t access the userId variable value from inside the onCreate method. I’m accessing the activity from two different activities so I have to check from which one I’m coming from, I do that with the caller but the value returned by the getDetailsUserId method is 0 all the time even though userId is a class variable.

If I initialize userId with 5 for example that’s the value returned by the getDetailsUserId method… not the value from the onCreate method.

public class Details extends Activity {

    long userId;

    long getDetailsUserId(){
        return userId; //This is the variable value I can't get.
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_details);
        getActionBar().setDisplayHomeAsUpEnabled(true);

        final String caller;

        //Get previous activity name
        caller = getIntent().getStringExtra("com.mysite.myapp.Caller");

        //Get user id from "List"
        if(caller.equals("List")){
            List userListId = new List();
            userId = userListId.getUserListId();
        }

        //Get user id from "Profile Saved"
        else if(caller.equals("ProfileSaved")){
            ProfileSaved savedUserId = new ProfileSaved();
            userId = savedUserId.getSavedUserId();
        }

}

Sorry, changed my previous answer. Tried it and it worked for me.

Here it is

public static class Details extends Activity {

   static long userId;

    long getDetailsUserId(){
        return userId; //This is the variable value I can't get.
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.grid_layout);
        getActionBar().setDisplayHomeAsUpEnabled(true);

        final String caller;

        //Get previous activity name
        caller = getIntent().getStringExtra("com.mysite.myapp.Caller");

        //Get user id from "List"
        if(caller.equals("List")){
            List userListId = new List();
            userId = userListId.getUserListId();
        }

        //Get user id from "Profile Saved"
        else if(caller.equals("ProfileSaved")){
            ProfileSaved savedUserId = new ProfileSaved();
            this.userId = savedUserId.getSavedUserId();
        }

}

}
