Use this As you have to send values from different intents not from the single one

int pos =poltype.getSelectedItemPosition();
int q1=pos;
Intent myIntent = new Intent(context1, FifthPage.class);
myIntent.putExtra("Q1", q1);                      
startActivity(myintent);

Intent myintent2 = new Intent(context1, SecondPage.class);
startActivity(myintent2);

In FirstPage, use:

int pos =poltype.getSelectedItemPosition();
int q1=pos;
Intent myIntent = new Intent(context1, FifthPage.class);
myIntent.putExtra("Q1", (int)q1);
startActivity(myintent);

In FifthPage Activity, use this

Intent mIntent = getIntent();
Bundle bundle = mIntent.getExtras();

    if (bundle != null) {
        // getting Q1
        int q1 = bundle.getInt("Q1");

    }

Edit: If you don't want to start Fifthpage, you can save Q1 value to SharedPreference and access it from there.

SharedPreference Usage:

In FirstPage:

SharedPreference sp = getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor spe = sp.edit();
spe.putInt("Q1", (int)q1);
spe.commit();

In FifthPage:

SharedPreference sp = getPreferences(Context.MODE_PRIVATE);
int q1 = sp.getInt("Q1", 0);

You are setting some integer value instead string somewhere in your toast code, check this link- http://stackoverflow.com/questions/17388586/android-content-res-resourcesnotfoundexception-string-resource-id – Amrit Pal Singh May 19 '15 at 11:47

You need only one intent, not two and you have to start your new activitiy with the intent that have your integer (myIntent not myIntent2).

Intent intent = new Intent(CurrentClass.this, NewClass.class);
intent.putExtra("name", integerValue)
startActivity(intent);

Start the activity with the intent, in which is your extra added and then try with this one when you want to get your value:

int Q1 = Integer.parseInt(getIntent().getExtras().get("Q1").ToString());
