How to get and set style attribute in code?

Suppose the following code:

          <MyCustomComponent
            style="@style/Base.TextAppearance.AppCompat.Headline"
            android:padding="@dimen/padding_default"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

In the custom component I have an EditText which I need to set its style attribute to @style/Base.TextAppearance.AppCompat.Headline in java code, according to the style attribute in the layout. How can I do that?

I am creating a custom component therefore I also need to know which style has been selected in layout by user of my component. Is it available through AttributeSet? If yes please let me know how?

For styling TextViews programmatically, you must have a style inheriting a TextAppearance style, and you can apply it using the following code:

if (Build.VERSION.SDK_INT < 23) { textView.setTextAppearance(context,android.R.style.TextAppearance_Small); } else { textView.setTextAppearance(android.R.style.TextAppearance_Small); }

Define a custom style in style.xml like this:

<style name="MyHeadlineTextAppearance" parent="Base.TextAppearance.AppCompat.Headline"/>

Then set it to your TextView as below:

textView.setTextAppearance(context, R.style.MyHeadlineTextAppearance);
