Vibrator振动器是Android给我们提供的用于机身震动的一个服务,例如当收到推送消息的时候我们可以设置震动提醒,也可以运用到游戏当中增强玩家互动性

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"/>
