  import android.widget.Button;
  import android.widget.TextView;
  
  
  public class MoneyActivity extends ActionBarActivity {
  
  private TextView txtMoney;
  private Button btnWork;
  private Button btnBuyClothes;
  int workMoney = 15;
  int buyClothesMoney = 20;
  int currentMoney;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_money);
  
      txtMoney = (TextView)findViewById(R.id.txtMoney);
  
      btnWork = (Button)findViewById(R.id.btnWork);
      btnWork.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              currentMoney = currentMoney + workMoney;
              txtMoney.setText(String.valueOf(currentMoney));
          }
      });
  
      btnBuyClothes = (Button)findViewById(R.id.btnBuyClothes);
      btnBuyClothes.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              currentMoney = currentMoney - buyClothesMoney;
              txtMoney.setText(String.valueOf(currentMoney));
