按任意按钮时如何振动设备。 我使用过此代码,但没有任何影响或振动
//click listener
imgNextBtn.setOnClickListener {
val vibe:Vibrator = activity?.getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vibe.vibrate(500)
Utilities.alertDialog(this,
activity!!,
mContent!!
}
}
或
//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!!
}
}
menifest:`
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />`

@ R2R给出的答案是完美的。但 API级别26 的vibrate()
类的Vibrator
方法已弃用。所以,我给你更新的代码:
您无需更改所有内容。只需在 MainActivity.kt 中更新振动的代码。
<强> MainActivity.kt:强>
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
}
}
}
}
}

使用kotlin工作样品进行振动试试这个
Manifest.xml
<uses-permission android:name="android.permission.VIBRATE" />
在kotlin:
val vibratorService = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
vibratorService.vibrate(500)
activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns: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"
>
<Button
android: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
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)
}
}
}

您可以创建fun
并从中使用(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)
}
}
在您的fragment
中:
vibratePhone()
最后在你manifest
中
<uses-permission android:name="android.permission.VIBRATE" />

简化它就像
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)
}
}
什么时候图案可能像
val pattern = longArrayOf(0, 200, 100, 300)
嗡嗡声和非嗡嗡声需要的元素->等待0毫秒,嗡嗡声200毫秒,等待100毫秒,嗡嗡声300毫秒
当然可以在清单中获得许可
<uses-permission android:name="android.permission.VIBRATE" />
希望,将来会对别人有帮助
