How do I get the data from the person who just logged in to my system?

Question

the previous question I wanted to know the validation and I already realized it , now I want to know how I took the data of the person who logged in and play to another screen and separate each data of the person for example name ai plays in a textview professional ai play in another textview ...

I’m trying a lot of different ways but none of them worked ?

import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {


    private Button cadastro; 
    private Button login;
    private EditText logar;
    private EditText senha;
     Intent it;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        login = (Button)findViewById(R.id.btnLogin);

        login.setOnClickListener(new View.OnClickListener() {





            @Override
            public void onClick(View arg0) {
                // como colocar o usuario e senha no lugar do null

                logar =(EditText)findViewById(R.id.login);
                String logarr=logar.getText().toString();
                senha=(EditText)findViewById(R.id.senha);
                String senhaa=senha.getText().toString();


                CriaBanco validar = new CriaBanco( MainActivity.this, MainActivity.this);

                validar.validar(logarr,senhaa);

            }
        });     



        cadastro = (Button)findViewById(R.id.btnCadastrar);

        cadastro.setOnClickListener(new View.OnClickListener() {
