protected static void startTimer() {
isTimerRunning = true;
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
elapsedTime += 1; //increase every sec
mHandler.obtainMessage(1).sendToTarget();
}
}, 0, 1000);
}
public Handler mHandler = new Handler() {
public void handleMessage(Message msg) {
StopWatch.time.setText(formatIntoHHMMSS(elapsedTime)); //this is the textview
}
};
Above code will work…
Note: Handlers must be created in your main thread so that you can modify UI content.
