title: R.java not generating R.id in Android
body: <p>Maybe my Googling skills aren't the greatest, but whenever I Google this problem, I only find solutions to when the whole R file isn't generated which isn't my problem.  Everything else is generating just fine, however, there is no ID within R, so I have no way of referencing the views in my XML.  I've already tried project->clean, and restarting the adb server and eclipse, neither to any avail.  All help is greatly appreciated.  Below is my code.</p>
  
  <pre><code>public class MainMenu extends Activity {
  
      /*
       * Class member variables
       */
      private Button mMicrophoneButton;
      private ListView mMessageList;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main_menu_layout);
          setWidgets();
      }
  
      private void setWidgets() {
          this.mMicrophoneButton = (Button) findViewById(R.id.bMicrophone);
      }
  
  }
  </code></pre>
  
  <p>Below is my XML, there's a lot of new stuff here that I don't recognize from previous projects I've done.  But I'm not finding any mistakes, which I know is usually the first cause of problems like this.:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

              android:layout_height="wrap_content"
              android:layout_width="wrap_content"
              android:text="test" /&gt;
  
      &lt;/ScrollView&gt;
  
      &lt;Button
