Vibrator public class MainActivity extends Activity { private Vibrator vibrator; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE); } public void click(View view) { // vibrator.vibrate(2000);//震动2s vibrator.vibrate(new long[] { 3000, 100, 100, 1000 }, -1); } } 代码详解 取得震动服务的句柄 vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE); 或者 vibrator = (Vibrator)getApplication().getSystemService(Service.VIBRATOR_SERVICE); 开始震动有两个接口 vibrator.vibrate(2000);/

Android振动器 android.os.Vibrator 1.Java层 frameworks/base/core/java/android/os/Vibrator.java Vibrator类的实力可以通过 getSystemService(VIBRATOR_SERVICE)获得实例。 两个方法：public abstract void vibrate(long milliseconds);/public abstract void vibrate(long[] pattern, int repeat); public abstract void cancel(); 查找路径：Activity.java-->ContextThemeWrapper.java-->ContextWrapper.java-->Context.java,getSystemService是Context.java类的抽象方法。其实现的类是ContextImpl.java，其中有段静态代码，注册所有context下能使用到的service。 registerService(VIBRATOR_SERVICE, new ServiceFetcher() { public Object createService(ContextImpl ctx) { return new SystemVibrator();
