Setting textSize programmatically

Question

textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, getResources().getDimension(R.dimen.result_font));

The following code works, but the R.dimen

Answer 1

You have to change it to TypedValue.COMPLEX_UNIT_PX because getDimension(id) returns a dimen value from resources and implicitly converted to px.

Java:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, 
                     getResources().getDimension(R.dimen.result_font));

Kotlin:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, 
                     resources.getDimension(R.dimen.result_font))
