not displaying calculation in textview from editview

I am trying to allow people to input hypothetical new loan information in to editText fields. Upon clicking on button "Calculator" I want it to calculate the monthly payment.

Below is the code on the calculator.java page I have.

public class AddDebt extends Activity implements OnClickListener {
Button Home;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_new_debt);


}

This part is for my Menu to switch between my pages (Activities):

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.default_menu, menu);

    MenuItem newDebt = menu.findItem(R.id.newDebt);
    Intent intent1 = new Intent(this, AddDebt.class);
    newDebt.setIntent(intent1);

    MenuItem About = menu.findItem(R.id.about);
    Intent intent2 = new Intent(this, About.class);
    About.setIntent(intent2);

    MenuItem Calcu = menu.findItem(R.id.Calcu);
    Intent intent3 = new Intent(this, Calculator.class);
    Calcu.setIntent(intent3);

    MenuItem Manu = menu.findItem(R.id.manu);
    Intent intent4 = new Intent(this, ManuPage.class);
    Manu.setIntent(intent4);
    return true;
}

I have "android:onClick="ButtonOnClick"" declared in my .xml on the Calculator button:

    public void ButtonOnClick(View v) {
    // TODO Auto-generated method stub
        switch (v.getId()) {
        case R.id.calculate:
            EditText myEdit = (EditText) findViewById(R.id.editBalance);
            String myEditValue = myEdit.getText().toString();
            int myEditBal = Integer.parseInt(myEditValue);

            EditText myEdit2 = (EditText) findViewById(R.id.editRate);
            String myEditValue2 = myEdit2.getText().toString();
            int myEditRate = Integer.parseInt(myEditValue2);

            EditText myEdit3 = (EditText) findViewById(R.id.editTerm);
            String myEditValue3 = myEdit3.getText().toString();
            int myEditTerm = Integer.parseInt(myEditValue3);

Also FYI: I know this is not a valid loan calculation, I'm using it to ensure I get a valid number:

            int editMnthlypmt = myEditBal + myEditRate + myEditTerm;

            TextView textMnthlypmt = new TextView(this);
            textMnthlypmt.setText("" + String.valueOf(editMnthlypmt));

        break;
    }
}

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

    }
}

I can input the data; however, it does not populate the answer in to my TextView field "textMnthlypmt". Any ideas?

You have created an instance of TextView but you haven't added to parentView...

try like this..

TextView textMnthlypmt = new TextView(this);
textMnthlypmt.setText("" + String.valueOf(editMnthlypmt));
parentView.addView(textMnthlypmt);//where parentView is parent layout defined in layout.activity_new_debt

Hope this helps..

check out you xml once again and

use a already declared text view

TextView textMnthlypmt = new TextView(this);

with this code you are creating a new text view but not putting it on activity.
