每日总结-android Vibrator

• 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! 比如:pattern为new int[200,400,600,800],就是让他在200,400,600,800这个时间交替启动与关闭振动器! 而第二个则是重复次数,如果是-1的只振动一次,如果是0的话则一直振动 还有其他两个方法用得不多~ 对了，使用振动器还需要在AndroidManifest.xml中添加下述权限： <uses-permission android:name="android.permission.VIBRATE"/>

• public class MainActivity extends AppCompatActivity implements View.OnClickListener {
