title: How to zoom in a TextView?
body: <p>I have declared the following xml code:</p>
  
  <pre><code>&lt;ScrollView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"&gt;
  
      &lt;HorizontalScrollView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"&gt;
  
              &lt;TextView
                  android:id="@+id/text"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"/&gt;
  
      &lt;/HorizontalScrollView&gt;
  
  &lt;/ScrollView&gt;
  </code></pre>
  
  <p>So, as you can I see, in the above <code>TextView</code> I set a huge amount of <strong>immutable</strong> text. I can slide both vertically and horizontally.</p>
  
  <p>But, how I cant modify any of these elements to "pinch" the device to <strong>zoom in and out</strong> accordingly? Is there any library that can help me out?</p>
