EditText to int using Integer.parseInt
<p>I'm new to programming and Android.  I'm making my best attempt at a simple app and I'm stuck!</p>

<p>I have two editTexts (set to accept numbers only) and a button.  The idea is to display the sum of the two user inputs when the button is pressed.  However, my app stops working and force closes when I click the button in the emulator.</p>

<p>Any help would be greatly appreciated.</p>

<pre><code>@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_prevailing_torque);
    Button calculatePrevailing = (Button) findViewById(R.id.button_calculatePrevailing);


    calculatePrevailing.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            TextView prevailingSetting = (TextView) findViewById(R.id.textViewSetting);
            EditText editTextPrevailing = (EditText) findViewById(R.id.editTextPrevailing);
            EditText editTextRecommended = (EditText) findViewById(R.id.editTextReccomended);

            int p = Integer.parseInt(editTextPrevailing.getText().toString());
            int r = Integer.parseInt(editTextRecommended.getText().toString());

            prevailingSetting.setText(r+p);
        }
    });
}
</code></pre>

<p>I've looked at several similar questions on here but I haven't been able to find anything that I can implement further than what I have already done.  But I am probably looking in the wrong places.
Thanks!</p>
