How To Vibrate Android Device On Button Click Using Vibrator Effects Using Kotlin?

How to vibrate an Android device coding with Kotlin when pressing any buttons? I have used this code below, but there aren't any effects or vibrations performed. //click listener

Solution 1:

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-permissionandroid:name="android.permission.VIBRATE" />

Solution 2:

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:

classMainActivity : AppCompatActivity() {

    overridefunonCreate(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 checkingif (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
                }
            }
        }
    }

}

Solution 3:

Vibration using kotlin working sample try this

Manifest.xml

<uses-permissionandroid: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.ConstraintLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"
><Buttonandroid:id="@+id/btn_vibrate"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="Vibrate"app:layout_constraintBottom_toBottomOf="parent"app:layout_constraintLeft_toLeftOf="parent"app:layout_constraintRight_toRightOf="parent"app:layout_constraintTop_toTopOf="parent" /></android.support.constraint.ConstraintLayout>

MainActivity.kt

classMainActivity : AppCompatActivity() {

    overridefunonCreate(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)

        }
    }
}

Solution 4:

Simplify it could be like

val buzzer = activity?.getSystemService<Vibrator>()

buzzer?.let {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                buzzer.vibrate(VibrationEffect.createWaveform(pattern, -1))
            } else {
                //deprecated in API 26
                buzzer.vibrate(pattern, -1)
            }
        }

When pattern could be like

valpattern= longArrayOf(0, 200, 100, 300)

Elements of buzzing and non-buzzing takes -> wait 0 ms, buzz 200ms, wait 100ms, buzz 300ms

Of course with permission in Manifest

<uses-permissionandroid:name="android.permission.VIBRATE" />

Hope, it will help somebody in future
