一、获得系统的Vibrator

        myVibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE);
        mContext = MainActivity.this;

二、判断并设置频率不同的震动器

 

abstract void cancel()：关闭或者停止振动器

abstract boolean hasVibrator()：判断硬件是否有振动器

void vibrate(long milliseconds)：控制手机振动为milliseconds毫秒

void vibrate(long[] pattern,int repeat):指定手机以pattern指定的模式振动

第一个参数：new int[200,400,600,800],在200,400,600,800这个时间交替启动与关闭振动器
第二个参数：重复次数,如果是-1的只振动一次,如果是0的话则一直振动

 public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_hasVibrator:
                Toast.makeText(mContext, myVibrator.hasVibrator() ? "当前设备有振动器" : "当前设备无振动器",
                        Toast.LENGTH_SHORT).show();
                break;
            case R.id.btn_short:
                myVibrator.cancel();
                myVibrator.vibrate(new long[]{100, 200, 100, 200}, 0);
                Toast.makeText(mContext, "短振动", Toast.LENGTH_SHORT).show();
                break;
            case R.id.btn_long:
                myVibrator.cancel();
                myVibrator.vibrate(new long[]{100, 100, 100, 1000}, 0);
                Toast.makeText(mContext, "长振动", Toast.LENGTH_SHORT).show();
                break;
            case R.id.btn_rhythm:
                myVibrator.cancel();
                myVibrator.vibrate(new long[]{500, 100, 500, 100, 500, 100}, 0);
                Toast.makeText(mContext, "节奏振动", Toast.LENGTH_SHORT).show();
                break;
            case R.id.btn_cancle:
                myVibrator.cancel();
                Toast.makeText(mContext, "取消振动", Toast.LENGTH_SHORT).show();
        }
    }

三、开启系统权限

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