how to set the Style Attribute Programmatically in Android?

Question

I have to set the style for a TextView which is created programmatically.

How do I implement style=\"@style/test\" programmaticall

Answer 1

setTypeface(Typeface.DEFAULT_BOLD, Typeface.BOLD_ITALIC);

It works for me

Answer 2

You can pass the style to view's constructor. This can be done in 2 ways:

1. Use ContextThemeWrapper and 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.

2. 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

Answer 3

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