# Vibration
# Getting Started with Vibration
Grant Vibration Permission
before you start implement code, you have to add permission in android manifest :
<uses-permission android:name="android.permission.VIBRATE"/>
Import Vibration Library
import android.os.Vibrator;
Get instance of Vibrator from Context
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
Check device has vibrator
void boolean isHaveVibrate(){
if (vibrator.hasVibrator()) {
return true;
}
return false;
}
# Vibrate Indefinitely
using the vibrate(long[] pattern, int repeat)
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
// Start time delay
// Vibrate for 500 milliseconds
// Sleep for 1000 milliseconds
long[] pattern = {0, 500, 1000};
// 0 meaning is repeat indefinitely
vibrator.vibrate(pattern, 0);
# Vibration Patterns
You can create vibration patterns by passing in an array of longs, each of which represents a duration in milliseconds. The first number is start time delay. Each array entry then alternates between vibrate, sleep, vibrate, sleep, etc.
The following example demonstrates this pattern:
- vibrate 100 milliseconds and sleep 1000 milliseconds
- vibrate 200 milliseconds and sleep 2000 milliseconds
long[] pattern = {0, 100, 1000, 200, 2000};
To cause the pattern to repeat, pass in the index into the pattern array at which to start the repeat, or -1
to disable repeating.
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(pattern, -1); // does not repeat
vibrator.vibrate(pattern, 0); // repeats forever
# Stop Vibrate
If you want stop vibrate please call :
vibrator.cancel();
# Vibrate for one time
using the vibrate(long milliseconds)
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(500);
