如何使用振动器效果在按钮点击时振动设备？使用Kotlin

Question

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!!
    }
}

要么

 //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" />`

Answer 1

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)
    }
}

而在你的fragment：

vibratePhone()

最后在你manifest：

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

@ R2R给出的答案是完美的.但是从API级别26 推荐vibrate()了Vibrator类的方法.所以,我给你更新的代码:

你不必改变一切.刚更新的代码振动的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
                }
            }
        }
    }

}

API 31 及更高版本已弃用 Vibrator 服务。要以正确的方式执行此操作，请按照此问题中的说明执行以下操作：

 fun vibrate(){
    val vib = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
        val vibratorManager =
            getSystemService(Context.VIBRATOR_MANAGER_SERVICE) as VibratorManager
        vibratorManager.defaultVibrator
    } else {
        @Suppress("DEPRECATION")
        getSystemService(VIBRATOR_SERVICE) as Vibrator
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        vib.vibrate(VibrationEffect.createOneShot(300, VibrationEffect.DEFAULT_AMPLITUDE) )
    }else{
        @Suppress("DEPRECATION")
        vib.vibrate(300)
    }
}

Answer 4

使用 kotlin 工作示例的振动试试这个

清单.xml

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

在科特林中：

 val vibratorService = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
        vibratorService.vibrate(500)

活动主文件

<?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)

        }
    }
}
