Change font in android -

i know question has been asked many times still not getting right.so please me.i want change font of textviews.i find code on google , end doing this

code

public class sliderfont extends textview {     public sliderfont(context context, attributeset attrs) {         super(context, attrs);          typeface typeface = typeface.createfromasset(context.getassets(), "fonts/redhead.ttf");         settypeface(typeface);     } } 

and used in xml

<pocketdocs.indiehustlers.com.pocketdocsv2.utils.sliderfont     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_gravity="center"     android:layout_marginleft="5dp"     android:text="awaited approval"     android:textcolor="#fff"     android:textsize="@dimen/edit_text_size" /> 

but still not getting desired font.

i have created assets folder

instead :

typeface typeface = typeface.createfromasset(context.getassets(), "fonts/redhead.ttf");         settypeface(typeface); 

try use :

typeface typeface = typeface.createfromasset(getresources().getassets(), "fonts/redhead.ttf");             yourtv.settypeface(typeface);
