title: Add static text before or after a TextView
body: <p>I'm new to Android Dev and I try to figure a gently way to add static text before and after a dynamic part in a TextView, without having to add 2 other TextView or add these content each time I update the dynamic part of my TextView.</p>
  
  <p>Something just like ::after or ::before with content propertie in CSS.</p>
  
  <p>Something which could look like this :</p>
  
  <pre><code>&lt;TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="10"
    android:textAfter=" km/h" /&gt;
  </code></pre>
  
  <p>I digged Google up and down (went to 3rd page sometimes) but I couldn't find any way to do this trick which appear pretty basic to me.</p>
