如何使用 Kotlin 使用振动器效果在单击按钮时振动 Android 设备?
How to vibrate Android device on button click using vibrator effects using Kotlin?
如何在按下任何按钮时使用 Kotlin 振动 Android 设备编码?我在下面使用了这段代码,但没有执行任何效果或振动。
//click listener
imgNextBtn.setOnClickListener {
val vibe:Vibrator = activity?.getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vibe.vibrate(500)
Utilities.alertDialog(this,
activity!!,
mContent!!
}
}
或者
//click listener
imgNextBtn.setOnClickListener {
val vibe:Vibrator = activity?.getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
var effect:VibrationEffect = VibrationEffect.createOneShot(1000, VibrationEffect.DEFAULT_AMPLITUDE);
vibe.vibrate(effect)
Utilities.alertDialog(this,
activity!!,
mContent!!
}
}
Android 清单:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
使用 kotlin 工作示例的振动试试这个
Manifest.xml
<uses-permission android:name="android.permission.VIBRATE" />
在科特林中:
val vibratorService = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator

@R2R 的回答很完美。但是 Vibrator
class 的 vibrate()
方法已从 API 级别 26 弃用 。所以,我给你更新的代码:
您不必更改所有内容。只需在 MainActivity.kt.
中更新 vibration 的代码
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
}
}
}
}
}
您可以创建一个 fun
并使用它 (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)
}
}
在你的 fragment
中:
vibratePhone()
终于在你身边manifest
:
<uses-permission android:name="android.permission.VIBRATE" />
简化它可能像
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)
}
}
什么时候模式可以像
val pattern = longArrayOf(0, 200, 100, 300)
嗡嗡声和非嗡嗡声的元素 -> 等待 0 毫秒,嗡嗡声 200 毫秒,等待 100 毫秒,嗡嗡声 300 毫秒
当然要在 Manifest 中获得许可
<uses-permission android:name="android.permission.VIBRATE" />
希望对以后的人有所帮助
