Question

我有一个用于振动功能的utils类，它在某些apis中工作但在另一个工作中没有工作

api 17正在运作

api 24无效

任何人都可以指导我为什么这段代码不起作用注意我采取了正确的许可

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

我的班级

public class VibrateUtils {


    public static void VibrateMethod(Context mContext , String PassedValue) {

        // Get instance of Vibrator from current Context
        Vibrator v = (Vibrator) mContext.getSystemService(Context.VIBRATOR_SERVICE);

        // Start without a delay
        // Vibrate for 500 milliseconds
        // Sleep for 1000 milliseconds
        long[] pattern = {0, 500, 1000};

        switch (PassedValue){

            case "1":
                // Start without a delay
                // Vibrate for 500 milliseconds   --> First time
                // Sleep for 1000 milliseconds
                pattern = new long[]{0, 500, 1000};
                break;

            case "2":
                // Start without a delay
                // Vibrate for 500 milliseconds  --> First time
                // Sleep for 1000 milliseconds
                // Vibrate for 500 milliseconds   --> Second time
                // Sleep for 1000 milliseconds
                pattern = new long[]{0, 500, 500 , 500 , 500 };
                break;

            case "3":
                // Start without a delay
                // Vibrate for 500 milliseconds  --> First time
                // Sleep for 1000 milliseconds
                // Vibrate for 500 milliseconds   --> Second time
                // Sleep for 1000 milliseconds
                // Vibrate for 500 milliseconds   --> Third time
                // Sleep for 1000 milliseconds
                pattern = new long[]{0, 500, 1000 , 500 , 1000  , 500 , 1000};
                break;

            case "4":
                // Start without a delay
                // Vibrate for 500 milliseconds  --> First time
                // Sleep for 1000 milliseconds
                // Vibrate for 500 milliseconds   --> Second time
                // Sleep for 1000 milliseconds
                // Vibrate for 500 milliseconds   --> Third time
                // Sleep for 1000 milliseconds
                // Vibrate for 500 milliseconds   --> Fourth time
                // Sleep for 1000 milliseconds
                pattern = new long[]{0, 500, 1000 , 500 , 1000  , 500 , 1000 , 500 , 1000};
                break;

        }



        // The '0' here means to repeat indefinitely
        // '0' is actually the index at which the pattern keeps repeating from (the start)
        // To repeat the pattern from any other point, you could increase the index, e.g. '1'
        if(Build.VERSION.SDK_INT >= 26){
            v.vibrate(VibrationEffect.createWaveform(pattern, VibrationEffect.DEFAULT_AMPLITUDE));
        }else{
            v.vibrate(pattern, -1);
        }

    }
}
