Votre question est "Comment faire vibrer un appareil Android pendant une longue durée (par exemple 2, 5, 10 minutes) ?" Personne n'a vraiment répondu à votre question, alors je vais essayer. J'ai écrit le code suivant pour faire vibrer le téléphone indéfiniment :
// get a handle on the device's vibrator
// should check if device has vibrator (omitted here)
Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
// create our pattern for vibrations
// note that the documentation states that the pattern is as follows:
// [time_to_wait_before_start_vibrate, time_to_vibrate, time_to_wait_before_start_vibrate, time_to_vibrate, ...]
// the following pattern waits 0 seconds to start vibrating and
// vibrates for one second
long vibratePattern[] = {0, 1000};
// the documentation states that the second parameter to the
// vibrate() method is the index of your pattern at which you
// would like to restart **AS IF IT WERE THE FIRST INDEX**
// note that these vibration patterns will index into my array,
// iterate through, and repeat until they are cancelled
// this will tell the vibrator to vibrate the device after
// waiting for vibratePattern[0] milliseconds and then
// vibrate the device for vibratePattern[1] milliseconds,
// then, since I have told the vibrate method to repeat starting
// at the 0th index, it will start over and wait vibratePattern[0] ms
// and then vibrate for vibratePattern[1] ms, and start over. It will
// continue doing this until Vibrate#cancel is called on your vibrator.
v.vibrate(pattern, 0);
Si vous voulez faire vibrer l'appareil pendant 2, 5 ou 10 minutes, vous pouvez utiliser ce code :
// 2 minutes
v.vibrate(2 * 60 * 1000);
// 5 minutes
v.vibrate(5 * 60 * 1000);
// 10 minutes
v.vibrate(10 * 60 * 1000);
Et enfin, si vous souhaitez n'écrire qu'une seule méthode pour faire cela (comme vous devriez le faire), vous pouvez écrire ce qui suit :
public void vibrateForNMinutes(Vibrator v, int numMinutesToVibrate) {
// variable constants explicitly set for clarity
// milliseconds per second
long millisPerSecond = 1000;
// seconds per minute
long secondsPerMinute = 60;
v.vibrate(numMinutesToVibrate * secondsPerMinute * millisPerSecond);
}
