Theme attributes for specific component types

Question

Can I define attributes in a theme that will apply only on specific components, such as an EditText, like what can be done in CSS with, e.g, .table? I know I can define a style and set it on all the components, but I'm looking for a more efficient way.

Answer 1

In your theme, add <item name="android:editTextStyle">@style/<your substyle name>:

<style name="My.Mega.Theme" >
    <item name="android:editTextStyle">@style/My.Mega.Theme.EditText</item>
</style>

<style name="My.Mega.Theme.EditText" parent="My.Mega.Theme">
    <item name="android:textSize">14sp</item>
</style>

Replace editTextStyle with buttonStyle for buttons, and so on.

You can even have analogs of css classes for controls of the same class, like:

(styles file):

<attr name="note" format="reference" />

<style name="My.Mega.Theme" >
    <item name="note">@style/My.Mega.Theme.SmallText</item>
</style>

(layout file):

<TextView style="?note"/>
