How to set unit for Paint.setTextSize()

Question

Is it possible to change the unit for Paint.setTextSize()? As far as I know, it\'s pixel but I like to set the text size in DIP for multiple screen support.

Answer 1

If your Paint object is being used to draw text on a Canvas, you can let the Canvas handle scaling for you.

When calling Canvas.drawText() the text size is first determined by the passed in Paint object, which can be set via Paint.setTextSize(). The text size is automatically scaled by Canvas based on the canvas density, which can be found using Canvas.getDensity().

When setting the text size on a paint object that will be drawn on Canvas, work with a unit value of dp or sp and let Canvas handle the scaling for you.
