Theme style for custom view

Question

My app has several themes from which the user can chose (red, blue, green etc.) Every theme has a corresponding button style (RedTheme => RedButton). Now I have created a custom view which slightly extends "Button" and unfortunately this button does not get any style, except I use the "style" attribute in a layout.xml. I don’t use any additional attributes, I just want that my Button style is applied. I want to do something similar than:

 <item name="android:imageButtonStyle">@style/ImageButtonmyTimeRed</item>

I have already read many other posts like this one: How to: Define theme (style) item for custom widget but I’m not 100% sure if this solution fits for me since I don’t need any additional attributes.

What is unclear for you? -> I just want that my Theme Button Style is applied for my derived Button. I also described how I want to use it — stefan, Jul 19 '15 at 18:24
I just have 2 -> ClockButton(Context context, AttributeSet attrs) — stefan, Jul 19 '15 at 18:30
public ClockButton(Context context, AttributeSet attrs, int defStyleRes) is not called — stefan, Jul 19 '15 at 18:34
I placed breakpoints in all of the three constructors and the one with two parameter is called — stefan, Jul 19 '15 at 18:36
you should call it directly with your own custom defStyleAttr (last param of View(Context context, AttributeSet attrs, int defStyleAttr)) — pskink, Jul 19 '15 at 18:40
How should I call it directly? It is definded in a layout.xml — stefan, Jul 19 '15 at 18:40
It seems that I found a verry verry simple solution. I had a look at android.widget.Button and I used the second constructor in my custom Button -> super(context, attrs, R.attr.buttonStyle); I'm still testing but this seems to work — stefan, Jul 19 '15 at 18:46
but you want use several styles. not just R.attr.buttonStyle, right? — pskink, Jul 19 '15 at 18:48
R.attr.buttonStyle takes the styles for android.widget.Button which are defined in my custom Themes (not the default Android button styles). Thats exactly what I wanted! — stefan, Jul 19 '15 at 18:50

I'm using the three parameter super constructor and pass the button style resource id. This works for all my custom themes. Thanks @pskink for pointing me into right direction.

public ClockButton(Context context, AttributeSet attrs) {
    super(context, attrs, R.attr.buttonStyle);
    ...
}

My theme looks like this:

<style name="LilaTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="buttonStyle">@style/ButtonmyTimeLila</item>
</style>
