Primeira Aba:

package com.example.androidtablayout;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

public class PhotosActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.photos_layout);

        final EditText nome = (EditText) findViewById(R.id.edtNome);

        Button Salvar = (Button) findViewById(R.id.btnSalvar);

        MySingleton mDados = MySingleton.getInstance ();

        mDados.setMyInt(100);

        mDados.setMyString("Testando classe");

//        String s = nome.getText().toString();

//        mDados.setMyString(s);

        Salvar.setOnClickListener(new View.OnClickListener() {

                  public void onClick(View v) {

                        String valor = nome.getText().toString();                 

                        Toast.makeText(getBaseContext(), valor, Toast.LENGTH_LONG).show();

                  }

            });

Segunda Aba:

package com.example.androidtablayout;

        final EditText Nome = (EditText) findViewById(R.id.edtNome);

        Button Salvar = (Button) findViewById(R.id.btnSalvar);

        Salvar.setOnClickListener(new View.OnClickListener() {

                  public void onClick(View v) {

                        // TODO Auto-generated method stub

                        String nome = Nome.getText().toString();            

                        Toast.makeText(getBaseContext(), nome, Toast.LENGTH_LONG).show();

                  }

            });

    }

}

Terceira Aba:

package com.example.androidtablayout;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

        Button Salvar = (Button) findViewById(R.id.btnSalvar);

        Salvar.setOnClickListener(new View.OnClickListener() {

                  public void onClick(View v) {

                  //    String nome = Nome.getText().toString();            

                  //    Toast.makeText(getBaseContext(), "teste", Toast.LENGTH_LONG).show();

                        MySingleton mDados = MySingleton.getInstance ();

                        int i = mDados.getMyInt();

                        String s = mDados.getMyString();

                    Toast.makeText(getBaseContext(), s, Toast.LENGTH_LONG).show();

                  }
