Question

I would like all the buttons of my android application use the same background image, that’s all buttons have attribute:

android:background="@drawable/my_btn_bg"

Is there any way to define this in one place and take effect in the whole application’s buttons? (instead of define the background on each button component)

I think define inside theme.xml could be a solution, but I do not know how to do it ? Could some one give me some hints?

Answer 1

For Android styles, you reference the preset attributes of R.attr. Here, you want to to reference android:buttonStyle. You can try this :

<style name="ApplicationStyle" parent="android:Theme">
<item name="android:buttonStyle">@style/yourButton</item>
</style>
