I have to set the style for a TextView which is created programmatically.
How do I implement style="@style/test" programmatically?
I have looked at the Android developer style documentation already, but it did not answer my question. Any ideas?

Dynamic style change is not currently supported. You must set the style before the view is create (in xml).

You just put style="@style/test" in the definition for your TextView in the layout xml file.
You can pass the style to view's constructor. This can be done in 2 ways:
Use
ContextThemeWrapperand setup your style as a Theme for it:ContextThemeWrapper wrappedContext = new ContextThemeWrapper(yourContext, R.style.test); TextView testView = new TextView(wrappedContext, null, 0);
And important note here - to properly set the style with ContextThemeWrapper we have to use three-argument constructor and set defStyleAttr parameter to 0. Otherwise the default button style will be applied to the view.
Starting from API 21 we can use constructor with 4 parameters:
View (Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes)
Where defStyleRes is your style ID
With the same remark - defStyleAttr should be 0
Comments
setTypeface(Typeface.DEFAULT_BOLD, Typeface.BOLD_ITALIC);
It works for me
