How to change the font on the TextView?

Question

How to change the font in a TextView, as default it\'s shown up as Arial? How to change it to Helvetica?

Answer 1

Maybe something a bit simpler:

public class Fonts {
  public static HashSet fonts = new HashSet<>();

  public static Typeface get(Context context, String file) {
    if (! fonts.contains(file)) {
      synchronized (this) {
        Typeface typeface = Typeface.createFromAsset(context.getAssets(), name);
        fonts.put(name, typeface);
      }
    }
    return fonts.get(file);
  }
}

// Usage
Typeface myFont = Fonts.get("arial.ttf");

(Note this code is untested, but in general this approach should work well.)
