I am developing an application that will be running in Kiosk Mode. In this application, if the user didn't do anything in the application within 5 minutes, the application will show a screen saver that is the logo of the application.
My question is, how can I code on detecting IDLE within 5 minutes?
A BETTER SOLUTION HERE...... VERY SIMPLE
I used countdown timer as bellow:
private long startTime = 15 * 60 * 1000; // 15 MINS IDLE TIME
private final long interval = 1 * 1000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
countDownTimer = new MyCountDownTimer(startTime, interval);
}
@Override
public void onUserInteraction(){
super.onUserInteraction();
//Reset the timer on user interaction...
countDownTimer.cancel();
countDownTimer.start();
}
public class MyCountDownTimer extends CountDownTimer {
public MyCountDownTimer(long startTime, long interval) {
super(startTime, interval);
}
@Override
public void onFinish() {
//DO WHATEVER YOU WANT HERE
}
@Override
public void onTick(long millisUntilFinished) {
}
}
CHEERS..........:)
You should try this, It will Notify with a toast on detecting IDLE 5 minutes.
Handler handler;
Runnable r;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
handler = new Handler();
r = new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "user Is Idle from last 5 minutes",
Toast.LENGTH_SHORT).show();
}
};
startHandler();
}
@Override
public void onUserInteraction() {
// TODO Auto-generated method stub
super.onUserInteraction();
stopHandler();//stop first and then start
startHandler();
}
public void stopHandler() {
handler.removeCallbacks(r);
}
public void startHandler() {
handler.postDelayed(r, 5*60*1000);
}
I think you could use http://developer.android.com/reference/android/app/Activity.html#dispatchTouchEvent(android.view.MotionEvent) and http://developer.android.com/reference/android/app/Activity.html#dispatchKeyEvent(android.view.KeyEvent) in your App to set a timestamp everytime a userinteraction takes place (simply override the methods and return false at the end so that the events will be propagated to underlying views) - then you can use some kind of timer which checks for the last timestamp of interaction recurringly and trigger your screen saver if your 5 minutes IDLE time are reached.
So in an Activity you simply override the before mentioned Methods like this:
@Override
public boolean dispatchTouchEvent (MotionEvent ev) {
timestamp = System.getCurrentTimeMilis();
return false; // return false to indicate that the event hasn't been handled yet
}
The dispatchKeyEvent and the other methods which you can override to determine user-activity should work fairly similar.
If you're using more than one Activity you may want to create a base class which extends Activity and Override all the dispatchXXXEvent you want to handle and which you than use as base class of all your Activities. But I guess the details of your implementation may be a little bit out of scope for the actual question :)
For the different possibilities of timers you may find useful info here: Scheduling recurring task in Android
try with:
private void startCount(int time) {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// Add here the code for showing the fullscreenlogo
}
}, time);
}
then, whenever you want to start the count you should add:
startCount(time); // Replace time with 60*5*1000 for 5 mins
if you want to start the count when the app got minimized, then use this:
@Override
public void onPause() {
super.onPause();
startCount(time);
}
