Question

I want to use Roboto font for All views in my android application ,how can I do that?

Answer 1

Create custom view such as TextView, EditText, etc.. Then you set in the constructors the setTypeface example below:

public class RobotoTextView extends TextView {

    public RobotoTextView(Context context) {
        super(context);
        setTypeface(Typeface
                .createFromAsset(context.getAssets(), "fontname.ttf"));

    }
}

And then just use this in you’re layout, instead of using the standard TextView use your custom class example below:

<packagename.RobotoTextView
            style="@style/usecustomstyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/yourid"/>
