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" programmatically?

I have looked at the Android developer style documentation already, but it did not answer my question. Any ideas?

you can refer to this answer on stack overflow https://mcmap.net/q/102750/-set-the-layout-weight-of-a-textview-programmatically – Vouge

Is this supported now ? – Alkali

Answer 1

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

what class i have to use for that? – Gammon

You just put style="@style/test" in the definition for your TextView in the layout xml file. – Alexia

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

setTypeface(Typeface.DEFAULT_BOLD, Typeface.BOLD_ITALIC);

It works for me
