java - android-how can a button remain in "clicked appearance" even after realease? -

in holo theme, click on button gets blue , shines moment. want button remains @ appearance, , @ next click comes normal appearance. how that?

update: code:

public class homeactivity extends sherlockactivity { org.holoeverywhere.widget.button bt; boolean ispressed = false;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.home_layout);     bt = (org.holoeverywhere.widget.button) findviewbyid(android.r.id.button1);     bt.setontouchlistener(new ontouchlistener() {          @override         public boolean ontouch(view v, motionevent event) {             if (event.getaction() == motionevent.action_up) {                 if (!ispressed) {                     ispressed = true;                 } else {                     ispressed = false;                 }                 bt.setpressed(ispressed);             }              return true;         }     }); } } 

first of all, can default images used sdk(button, check box, whatever is) location ->

~\android-sdk\platforms\android-18\data\res\drawable-hdpi

here i'm looking api-18. use whatever version support holo theme.

from there, can find image btn_default_pressed_holo_dark.9.png .

copy-paste project drawable-hdpi folder. first step. now,

public class mainactivity extends activity {     button b;     drawable back;     int flag=0;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         b=(button) findviewbyid(r.id.button1);          back=b.getbackground();          b.setonclicklistener(new onclicklistener() {              @override             public void onclick(view v) {                    if(flag==0){                     b.setbackgroundresource(r.drawable.btn_default_pressed_holo_dark);                     flag=1;                     }                 else{                     flag=0;                     b.setbackground(back);                 }             }         });     }   } 

check :)
