Create Custom Font which one is faster and best way?

I am new in android and I want use my custom font for my app. I wrote 2
ways creating custom font. Could you tell me guys which one is better and
faster. first way is using singleton class second way is create my own
textview.
with singleton
public class FontFactory {
private static FontFactory instance;
private HashMap<String, Typeface> fontMap = new HashMap<String,
Typeface>();
private FontFactory() {
}
public static FontFactory getInstance() {
if (instance == null){
instance = new FontFactory();
}
return instance;
}
public Typeface getFont(DefaultActivity pActivity,String font) {
Typeface typeface = fontMap.get(font);
if (typeface == null) {
typeface =
Typeface.createFromAsset(pActivity.getResources().getAssets(),
"fonts/" + font);
fontMap.put(font, typeface);
}
return typeface;
}
}
with own textview
public class MyTextView extends TextView {
public MyTextView(Context context) {
super(context);
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setFonts(context,attrs);
}
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setFonts(context,attrs);
}
private void setFonts(Context context, AttributeSet attrs){
TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.MyTextView_customFont);
String ttfName =
a.getString(R.styleable.MyTextView_customFont_ttf_name);
setCustomTypeFace(context, ttfName);
}
public void setCustomTypeFace(Context context, String ttfName) {
Typeface font = Typeface.createFromAsset(context.getAssets(),
"fonts/MuseoSansCyrl_"+ttfName+".otf");
setTypeface(font);
}
@Override
public void setTypeface(Typeface tf) {
super.setTypeface(tf);
}
}
