How to vibrate Android device on button click using vibrator effects using Kotlin?
You can create a fun
and use from it (Kotlin
):
fun Fragment.vibratePhone() {
val vibrator = context?.getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
if (Build.VERSION.SDK_INT >= 26) {
vibrator.vibrate(VibrationEffect.createOneShot(200, VibrationEffect.DEFAULT_AMPLITUDE))
} else {
vibrator.vibrate(200)
}
}
And in your fragment
:
vibratePhone()
Finally in you manifest
:
<uses-permission android:name="android.permission.VIBRATE" />
Answer given by @R2R is perfect. But vibrate()
method of Vibrator
class is deprecated from API Level 26. So, I am giving you the updated code:
You don't have to change everything. Just update the code for vibration in MainActivity.kt.
MainActivity.kt:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main);
val btn_click_me = findViewById(R.id.btn_vibrate) as Button
btn_click_me.setOnClickListener {
val vibrator = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
if (vibrator.hasVibrator()) { // Vibrator availability checking
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
vibrator.vibrate(VibrationEffect.createOneShot(500, VibrationEffect.DEFAULT_AMPLITUDE)) // New vibrate method for API Level 26 or higher
} else {
vibrator.vibrate(500) // Vibrate method for below API Level 26
}
}
}
}
}
Vibration using kotlin working sample try this
Manifest.xml
<uses-permission android:name="android.permission.VIBRATE" />
In kotlin:
val vibratorService = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vibratorService.vibrate(500)
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

<Button
android:id="@+id/btn_vibrate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main);
val btn_click_me = findViewById(R.id.btn_vibrate) as Button
btn_click_me.setOnClickListener {
val vibratorService = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vibratorService.vibrate(500)
}
}
}
