debugging - Eclipse Android - Debugger doesn't stop at breakpoint on OnClick method -

i want debug onclick method in saveactivity:

public class saveactivity extends activity {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_save);      getactionbar().setdisplayhomeasupenabled(true); }  // button // (http://developer.android.com/training/implementing-navigation/ancestral.html) @override public boolean onoptionsitemselected(menuitem item) {     switch (item.getitemid()) {     case android.r.id.home:         // called when home (up) button pressed         // in action bar.         intent parentactivityintent = new intent(this, mainactivity.class);         parentactivityintent.addflags(intent.flag_activity_clear_top                 | intent.flag_activity_new_task);         startactivity(parentactivityintent);         finish();         return true;     }     return super.onoptionsitemselected(item); }  public void onclick(view view) {      switch (view.getid()) {   // <-- on line breakpoint     case r.id.location_save:          edittext formname = (edittext) findviewbyid(r.id.location_name);         string locationname = formname.gettext().tostring();         edittext formdesc = (edittext) findviewbyid(r.id.location_desc);         string locationdesc = formdesc.gettext().tostring();         // example new york         string locationlatitude = "40.714353";         string locationlongitude = "-74.005973";          databasehandler db = new databasehandler(this);         location newlocation = new location(locationname, locationdesc,                 locationlatitude, locationlongitude);         db.addlocation(newlocation);         intent myintent = new intent(saveactivity.this, detailactivity.class);         myintent.putextra("id", newlocation.getid());          saveactivity.this.startactivity(myintent);      } } 

}

now added breakpoint on switch-statemant in onclick method. click on button in activity_save.xml:

<button    android:id="@+id/location_save"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="@string/location_save" > </button> 

so should stop @ breakpoint, nothing happend.
did wrong?

add in button layout bind method onclick:

android:onclick="onclick"
