title: Implement onClick only for a TextView compound drawable
body: <p>I need to have some text with a drawable on the left and I want to execute some code when the user clicks/touches the image (only the image, not the text), so I used a <em>LinearLayout</em> with a <em>TextView</em> and an <em>ImageView</em> which is clickable and launches an onClick event. The XML parser suggests me to replace this with a <em>TextView</em> with a <em>compound drawable</em>, which would draw the same thing with far less lines of <em>XML</em>.. My question is "can I specify I want to handle an onClick event only on the drawable of the <em>TextView</em> and not on the <em>TextView</em> itself? I've seen some solutions which involves writing your own extension of <em>TextView</em>, but I'm only interested in being able to do it within the layout resource, if possible, otherwise I'll keep the following <em>XML</em> code:</p>
  
  <pre><code>&lt;LinearLayout
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:gravity="center"
          android:orientation="horizontal" &gt;
  
          &lt;TextView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:gravity="bottom"
              android:paddingTop="10dp"
              android:paddingLeft="10dp"
              android:paddingRight="10dp"
              android:text="@string/home_feedback_title"
              android:textColor="@android:color/primary_text_dark"
              android:textStyle="bold" 
              android:paddingBottom="4dp"/&gt;
  
  
          &lt;ImageView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:src="@drawable/action_feedback" 
              android:clickable="true"
              android:onClick="onClickFeedback"
              android:contentDescription="@string/action_feedback_description"/&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
