How do You Center a TextView in Layout?
- by Ken
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?
Here's the portion of my layout that does this:
<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">
<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"/>
<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" />
<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"/>
</LinearLayout>
