Appending a TextView
<p>I have an app which at current will on the press of a button eg. the number 1 button change a text view to have the number 1 in it. What i need to do is append the view so that say when the number 3 is pressed the text view will say 13 instea of just 3. Here is the switch statement i'm using to handle the button presses.</p>

<pre><code>@Override
public void onClick(View c) {

    switch (c.getId()) 
    {
        case R.id.keypad_1:
            TextView prs1 = (TextView) findViewById(R.id.diff);
            prs1.setText("1");

    }

}
</code></pre>
