title: TextAppearance property of TextView in Android
body: <p>I am working on android application where I am using <code>TextView</code> to display the text on screens. </p>
  
  <p>I am using this property for the <code>TextView</code> to set the size of the text <code>android:textAppearance="?android:attr/textAppearanceMedium"</code>.</p>
  
  <p>Do I need to set the size of that text also or it does automatically manage by Android OS ?</p>
  
  <p>Thanks in advance.</p>
