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"/>
