android - Add custom font to all LinearLayout textviews -

i add linear layout , multiple textviews programmatically , set custom font texts,

i did in bellow way , works .

mainactivity 1:

 public class mainactivity extends activity {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main);       linearlayout ll = (linearlayout)findviewbyid(r.id.linearlayout);          textview tv = new textview(this);         tv.setgravity(gravity.right);         tv.settextcolor(color.green);         tv.settextsize(40);             ll.addview(tv);         typeface face4=typeface.createfromasset(getassets(),"bfantezy.ttf");              tv.settypeface(face4);         tv.settext(html.fromhtml(getstring(r.string.trip)));              imageview divider = new imageview(this);         linearlayout.layoutparams lp =           new linearlayout.layoutparams(layoutparams.match_parent, 5);         lp.setmargins(10, 10, 10, 10);         divider.setlayoutparams(lp);         divider.setbackgroundcolor(color.blue);         ll.addview(divider);          textview tv1 = new textview(this);               tv1.setgravity(gravity.right);         tv1.settextsize(40);         ll.addview(tv1);         typeface face1=typeface.createfromasset(getassets(),"bfantezy.ttf");              tv1.settypeface(face1);         tv1.settext(html.fromhtml(getstring(r.string.trip1)));          imageview divider1 = new imageview(this);         linearlayout.layoutparams lp1 =           new linearlayout.layoutparams(layoutparams.match_parent, 5);         lp1.setmargins(10, 10, 10, 10);         divider1.setlayoutparams(lp1);         divider1.setbackgroundcolor(color.blue);         ll.addview(divider1);          textview tv2 = new textview(this);         tv2.setgravity(gravity.right);         tv2.settextsize(40);         ll.addview(tv2);         typeface face2=typeface.createfromasset(getassets(),"bfantezy.ttf");              tv2.settypeface(face2);         tv2.settext(html.fromhtml(getstring(r.string.trip2)));          imageview divider3 = new imageview(this);         linearlayout.layoutparams lp3 =           new linearlayout.layoutparams(layoutparams.match_parent, 5);         lp3.setmargins(10, 10, 10, 10);         divider3.setlayoutparams(lp3);         divider3.setbackgroundcolor(color.blue);         ll.addview(divider3);                                 }                   } 

but recall

typeface.createfromasset(getassets() 

with each text ,its heavy way apply custom font , try make custom view bellow doesn't set custom font texts:

mainactivity:

  public class mainactivity extends activity {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main);      linearlayout ll = (linearlayout)findviewbyid(r.id.linearlayout);      // add text view     textview tv = new textview(this);     tv.setgravity(gravity.right);     tv.settextcolor(color.green);     tv.settextsize(40);         ll.addview(tv);     tv.settext(html.fromhtml(getstring(r.string.trip)));          imageview divider = new imageview(this);     linearlayout.layoutparams lp =       new linearlayout.layoutparams(layoutparams.match_parent, 5);     lp.setmargins(10, 10, 10, 10);     divider.setlayoutparams(lp);     divider.setbackgroundcolor(color.blue);     ll.addview(divider);       textview tv1 = new textview(this);           tv1.setgravity(gravity.right);     tv1.settextsize(40);     ll.addview(tv1);     tv1.settext(html.fromhtml(getstring(r.string.trip1)));      imageview divider1 = new imageview(this);     linearlayout.layoutparams lp1 =       new linearlayout.layoutparams(layoutparams.match_parent, 5);     lp1.setmargins(10, 10, 10, 10);     divider1.setlayoutparams(lp1);     divider1.setbackgroundcolor(color.blue);     ll.addview(divider1);       textview tv2 = new textview(this);     tv2.setgravity(gravity.right);     tv2.settextsize(40);     ll.addview(tv2);     tv2.settext(html.fromhtml(getstring(r.string.trip2)));      imageview divider3 = new imageview(this);     linearlayout.layoutparams lp3 =       new linearlayout.layoutparams(layoutparams.match_parent, 5);     lp3.setmargins(10, 10, 10, 10);     divider3.setlayoutparams(lp3);     divider3.setbackgroundcolor(color.blue);     ll.addview(divider3); }} 

customtextview:

    public class customtextview extends textview {      public customtextview(context context, attributeset attrs, int defstyle) {         super(context, attrs, defstyle);         init();     }      public customtextview(context context, attributeset attrs) {         //call constructor has complete definition         this(context, attrs, 0);         init();     }      public customtextview(context context) {         super(context);         init();     }      private void init() {              typeface tf = typeface.createfromasset(getcontext().getassets(), "bfantezy.ttf");             settypeface(tf);         }     } 

any appreciated , thanks.

instead of creating font assets every time, create "fontfactory" , reuse same one.

public class fontfactory {  private static typeface t1;  public static typeface getbfantezy(context c) {     if (t1 == null) {         t1 = typeface.createfromasset(c.getassets(), "bfantezy.ttf");     }     return t1; }   private static typeface t2;  public static typeface getotherfont(context c) {     if (t2 == null) {         t2 = typeface.createfromasset(c.getassets(), "otherfont.ttf");     }     return t2; } } 

then use in code :

tv1.settypeface(fontfactory.getbfantezy(getcontext()); 

you no longer have worry creating typeface. if needs it, factory create it. can add similar methods handle other typefaces wish use.
