Vibration

Vibrates the device.

Example

import React from "react";
import { Button, Platform, Text, Vibration, View, SafeAreaView, StyleSheet } from "react-native";

const Separator = () => {
  return <View style={Platform.OS === "android" ? styles.separator : null} />;
}

export default function App() {
  const ONE_SECOND_IN_MS = 1000;

  const PATTERN = [
    1 * ONE_SECOND_IN_MS,
    2 * ONE_SECOND_IN_MS,
    3 * ONE_SECOND_IN_MS
  ];

  const PATTERN_DESC =
    Platform.OS === "android"
      ? "wait 1s, vibrate 2s, wait 3s"
      : "wait 1s, vibrate, wait 2s, vibrate, wait 3s";

  return (
    <SafeAreaView style={styles.container}>
      <Text style={[styles.header, styles.paragraph]}>Vibration API</Text>
      <View>
        <Button title="Vibrate once" onPress={() => Vibration.vibrate()} />
      </View>
      <Separator />
      {Platform.OS == "android"
        ? [
            <View>
              <Button
                title="Vibrate for 10 seconds"
                onPress={() => Vibration.vibrate(10 * ONE_SECOND_IN_MS)}
              />
            </View>,
            <Separator />
          ]
        : null}
      <Text style={styles.paragraph}>Pattern: {PATTERN_DESC}</Text>
      <Button
        title="Vibrate with pattern"
        onPress={() => Vibration.vibrate(PATTERN)}
      />
      <Separator />
      <Button
        title="Vibrate with pattern until cancelled"
        onPress={() => Vibration.vibrate(PATTERN, true)}
      />
      <Separator />
      <Button
        title="Stop vibration pattern"
        onPress={() => Vibration.cancel()}
        color="#FF0000"
      />
    </SafeAreaView>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "center",
    paddingTop: 44,
    padding: 8
  },
  header: {
    fontSize: 18,
    fontWeight: "bold",
    textAlign: "center"
  },
  paragraph: {
    margin: 24,
    textAlign: "center"
  },
  separator: {
    marginVertical: 8,
    borderBottomColor: "#737373",
    borderBottomWidth: StyleSheet.hairlineWidth
  }
});

Android apps should request the android.permission.VIBRATE permission by adding <uses-permission android:name="android.permission.VIBRATE"/> to AndroidManifest.xml.

The Vibration API is implemented as a AudioServicesPlaySystemSound(kSystemSoundID_Vibrate) call on iOS.

Methods

`vibrate()`

Vibration.vibrate(?pattern: number | Array<number>, ?repeat: boolean)

Triggers a vibration with a fixed duration.

On Android, the vibration duration defaults to 400 milliseconds, and an arbitrary vibration duration can be specified by passing a number as the value for the pattern argument. On iOS, the vibration duration is fixed at roughly 400 milliseconds.

The vibrate() method can take a pattern argument with an array of numbers that represent time in milliseconds. You may set repeat to true to run through the vibration pattern in a loop until cancel() is called.

On Android, the odd indices of the pattern array represent the vibration duration, while the even ones represent the separation time. On iOS, the numbers in the pattern array represent the separation time, as the vibration duration is fixed.

Parameters:

Name	Type	Required	Description	Platform
pattern	number	No	Vibration duration in milliseconds. Defaults to 400 ms.	Android
pattern	Array of numbers	No	Vibration pattern as an array of numbers in milliseconds.	Android, iOS
repeat	boolean	No	Repeat vibration pattern until cancel(), default to false.	Android, iOS

`cancel()`

Vibration.cancel();

Call this to stop vibrating after having invoked vibrate() with repetition enabled.
