I am trying to set the textsize at a global level and cannot figure or find a way to do it.
For example I have something like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id = "@+id/Table"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:shrinkColumns="*"
android:stretchColumns="*">
</TableLayout>
</ScrollView>
The TableRows and TextViews themselves are generated dynamically depending on user input.
The problem is I would like to set the base textSize globally based on a resource file without having to go and touch a bunch of code. Is there a way to tell the app, "hey app, use this as your base textSize for all the textViews?"
Or phrased another way, in HTML I can set the font size at the body, div, and table levels. Is there something analogous I can do at one the layout (LinearLayout, TableLayout, ScrollView, etc.) levels?
You should think of this as the normal font size, and basically everything else a variation on it. For instance, while 14sp is the default text size when the text can be quite long, when there's only a small modal with a bit of text, it's 16sp! Notice that it's a bit lighter to make up for this size boost.
To set the global styling for all TextView
s, set the android:textViewStyle
attribute in a custom theme and apply the theme to your application or individual activities.
Pseudocode:
<style name="MyTheme" parent="android:Theme">
<item name="android:textViewStyle">@style/MyTextView</item>
</style>
<style name="MyTextView" parent="android:Widget.TextView">
<item name="android:textSize">14sp</item>
</style>
...
<activity android:theme="@style/MyTheme">
