Make a public type face method in Android

Question

I am trying to apply a custom font in different Activities, right now I have the following code in the onCreate() in my MainActivity:

String fontTitle = "fonts/OpenSans-Bold.ttf";
Typeface titleFont = Typeface.createFromAsset(getAssets(), fontTitle);
page_title.setTypeface(titleFont);

I want to know if it is possible to make the Typeface public so I can access it in other activities.

I created a class called FontHelper:

public class FontHelper extends MainActivity {

    // path for the fonts
    String fontTitle = "fonts/OpenSans-Bold.ttf";

    Typeface titleFont = Typeface.createFromAsset(getAssets(), fontTitle);

}

but in other Activities when I use textView.setTypeface(FontHelper.titleFont) I get an error. How can I fix this error?

Answer 1

You can use a static factory method to create your Typeface instance for each Activity like this:

public class FontHelper {

    private static final String FONT_PATH = "fonts/OpenSans-Bold.ttf";

    public static Typeface getCustomTypeFace(Context context) {
        return Typeface.createFromAsset(context.getAssets(), FONT_PATH);
    }
}

You can use it like this:

public class ExampleActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        final Typeface typeface = FontHelper.getCustomTypeFace(this);
        ...
    }
}
