I've crated Log in screen, and if user mistake 3 times i want to show timer of 2 min. I want that timer to be visually shown on the screen. I'll try this code and it's work, but I don't know how to display timer on screen.
Handler handler = new Handler();
long waitingTime = 2 * 60 * 1000; // 2 min
handler.postDelayed(new Runnable() {
@Override
public void run()
{
//Do something after 2 min
}
}, waitingTime);
You need to have Handler
called every second and update the UI during every pass. When you reach 2 mins you can cancel the handler.
Code should be like this:
final Handler handler = new Handler();
//class variable
count = 0;
handler.post(new Runnable() {
@Override
public void run() {
updateCounter(count++);
if(count < 120) {
handler.postDelayed(this, 1000);
}
}
});
And function to update counter:
private void updateCounter(final int count) {
runOnUiThread(new Runnable() {
@Override
public void run() {
// you have the seconds passed
// do what ever you want
}
});
}
