title: CheckedTextView not clickable
body: <p>Hi i setup a CheckedTextView but I can't get the onClick event functioning.
  I put the onClick code in the onCreate of the main.layout but I get a nullpointer at line 101, which is chkBox.setOnClickListener(new View.OnClickListener().
  The Listview is created in the onPostExecute of a AsyncTask.
  Can someone please help?</p>
  
  <p>My CheckedTextView:</p>
  
  <pre><code>&lt;CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"  
           android:id="@+id/listCheckboxview"  
           android:layout_width="wrap_content"  
           android:layout_height="wrap_content"  
           android:layout_weight="1" android:gravity="left"  
           android:textColor="#0075AB"  android:textStyle="bold"  android:textSize="14dip" 
           android:checkMark="?android:attr/listChoiceIndicatorMultiple"   
           android:clickable="true" 
           android:focusable="true" 
           android:text=""  
           /&gt; 
  </code></pre>
  
  <p>My onClick event:</p>
  
  <pre><code>CheckedTextView chkBox = (CheckedTextView) findViewById(R.id.listCheckboxview); 
          chkBox.setOnClickListener(new View.OnClickListener() { 
          public void onClick(View v) 
          { 
              ((CheckedTextView) v).toggle(); 
          } 
      });
  </code></pre>
