Styling all TextViews(or custom view) without adding the style attribute to every TextView

Question

Is there a way to format all TextViews, Buttons or whatever with a theme ? Like in CSS when i want to format all a-tags

a{ /some css here/ }

I want to do that in android via xml when I'm applying a theme to my application. Any ideas ?Thanks

Update 1.0: I want to create a theme that formats the text in all TextViews green and in all EditTexts red. So that i just apply the theme and I never have to worry about the style attribute!

Update 1.1: So I found some that piece of code and I think that's a good beginning

<item name="android:textViewStyle">@style/MyTextView</item>
<item name="android:buttonStyle">@style/MyButton</item>

I think thats the answer to my question. But I have another one. I want to write my own ActionBar and wanted to know how I can apply a default style or default attributes (again without adding the style attribute in the layout xml :P )

I have a class

public class ActionBar extends LinearLayout{ }

and I'm gonna use it like that in my application

<at.bartinger.uil.ActionBar>....</at.bartinger.uil.ActionBar>

The ActionBar should have some default attributes (like height and width) and then adding some custom style attributes which could change from app to app (like background)

Answer 1

yes you can you can apply a theme to the whole application and then all your textviews will have that style.

Inside the styles.xml file you have to define your CustomTheme

for example:

<style name="CustomTheme" parent="android:Theme.Light">
  <item name="android:windowBackground">@color/custom_theme_color</item>
  <item name="android:colorBackground">@color/custom_theme_color</item>
</style>

you add something like text "android:textStyle="myStyle" and specify the details in Mystyle
