add onclicklistener start.setonclicklistener(startcounter)
or can way
bstart.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { startcounter(v); } }); edit
let's make change on code see if it's code or not.
first of delete line of code :
android:onclick="startcounter" then on pushup_counter class change header :
public class pushup_counter extends activity implements sensoreventlistener, onclicklistener { you have add on oncreate() line of code :
start.setonclicklistener(this); then have add method onclick() looks :
@override public void onclick(view v) { // getid() returns view's identifier. switch(v.getid()){ case r.id.bstart; // todo auto-generated method stub smgr=(sensormanager)getsystemservice(sensor_service); sensor=smgr.getdefaultsensor(sensor.type_proximity); smgr.registerlistener(this, sensor,sensormanager.sensor_delay_normal); stop.setenabled(true); break; } } comment rest of code if gives error, try button , let me know if works.
