title: How to write a selector for an element with a Class that has a $ sign
body: <p>I'm working on mobile test automation. Basically I'm trying to select a new date in the android emulator using APPIUM with Eclipse (HELIOS) with JAVA. The class name for the time picker is:</p>
  
  <p><code>android.widget.RadialTimePickerView$RadialPickerTouchHelper</code></p>
  
  <p>As you can there is dollar sign($). If I use the following syntax.  </p>
  
  <pre><code>List timeButtons = driver.findElements(By.xpath("//android.widget.RadialTimePickerView$RadialPickerTouchHelper"));</code></pre>
  
  <p>I get an error message invalid XPATH/CSS selector.</p>
