Android Software Back Button Not Returning To Previous View
<p>I've been looking for over a month and I cannot get this resolved anywhere. Whenever I hit the back button my app closes. I've searched for <code>finish()</code> I've overridden the <code>onBackPressed()</code>, I just cannot seem to solve this issue.</p>

<pre><code>public class Toasty extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_toasty);

    Button button = (Button) findViewById(R.id.button1);

    button.setOnClickListener(new OnClickListener() {

          public void onClick(View arg0) {
             Toast.makeText(getApplicationContext(),
                     "Here's your toast!", Toast.LENGTH_LONG).show();
             setContentView(R.layout.activity_show_toast);
          }
    });
  }
}
</code></pre>

<p>This is pretty much all I do. It pops up on the next screen with a text view and a Toast pops up. Then I press that back button and the app exits when all I want to do is reset so that the button can be pressed again.</p>
