Answer 1

Please check below line in your ClassTwo.java :

 TextView text = (TextView) inflater.inflate(R.layout.ClassOne, null);

Here layout xml file ClassOne.xml has root as a ScrollView . So when you will inflate that layout, you need to cast it as ScrollView or View parent of all views.

It is good practice to cast every inflated layout as View and then get all different views using findViewById() .

So change your line as below:

 View rootView = inflater.inflate(R.layout.ClassOne, null);

Thanks

You can also use Intent to change text of a textView which is of another Activity from current Activity.

In current Activity:-

Intent intent= new Intent(CurrentActivity.this,CallingActivity.class);
                intent.putExtra("key","Review changed from a different activity");
                startActivity(intent);
                finish();

In onCreate() of your calling Activity:-

Intent mIntent=getIntent();
        if(mIntent!=null){
            String msg=mIntent.getStringExtra("key");
            textView.setText(msg);
        }
