title: How do You Center a TextView in Layout?
body: <p>I have a complex layout, part of which features a value centered over a label, with + and - buttons on either side of the value.  I want the value to center between the buttons, whether it is "1" or "99".  It looks fine when it's a 2-digit number like "99", but when it's a single digit the number is left-justified.  How do I properly center that value?</p>
  
  <p>Here's the portion of my layout that does this:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_above="@id/runway_label"
      android:layout_centerHorizontal="true"
      android:orientation="horizontal"&gt;
  
      &lt;ImageView
          android:id="@+id/dec_runway_button"
          android:src="@drawable/minus_button"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_gravity="center_vertical"/&gt;
  
      &lt;TextView
          android:id="@+id/runway_value"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:textColor="#FFFFFF"
          android:textStyle="bold"
          android:textSize="40.0sp"
          android:minWidth="50sp"
          android:layout_centerInParent="true"
          android:layout_gravity="center"
          android:shadowColor="#333333"
          android:shadowDx="2.0"
          android:shadowDy="2.0"
          android:shadowRadius="3.0" /&gt;
  
      &lt;ImageView
          android:id="@+id/inc_runway_button"
          android:src="@drawable/plus_button"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_gravity="center_vertical"/&gt;
  
  &lt;/LinearLayout&gt;
