it will help you

change the position of your

setContentView(R.layout.res2);

instead of your coding put these lines in the oncreate

     super.onCreate(savedInstanceState);
     setContentView(R.layout.res2);
     ans3=(TextView)findViewById(R.id.textView5);
     ans=(TextView)findViewById(R.id.textView2);
     ans2=(TextView)findViewById(R.id.textView4);
     ans4=(TextView)findViewById(R.id.textView6);

Change your oncreate() method

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.res2);
    ans3=(TextView)findViewById(R.id.textView5);
    ans=(TextView)findViewById(R.id.textView2);
    ans2=(TextView)findViewById(R.id.textView4);
    ans4=(TextView)findViewById(R.id.textView6);
}
