我尝试了以下方法,但它不能完美地工作。如果设备保持正常,那么它也会触发抖动事件。
@Override
public void onSensorChanged(SensorEvent event) {
// TODO Auto-generated method stub
long curTime = System.currentTimeMillis();
// only allow one update every 200Ms.
if ((curTime - lastUpdate) > 200) {
lastUpdate = curTime;
x = event.values[SensorManager.DATA_X];
y = event.values[SensorManager.DATA_Y];
z = event.values[SensorManager.DATA_Z];
Vibrator vibrate = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
if (Round(y, 4) > 22) {
vibrate.vibrate(200);
Log.d("sensor", "==== Up Detected===");
} else if (Round(y, 4) < -20) {
vibrate.vibrate(200);
Log.d("sensor", "==== Down Detected=== ");
}
mLastX = x;
mLastY = y;
mLastZ = z;
}
}
public static float Round(float Rval, int Rpl) {
float p = (float) Math.pow(10, Rpl);
Rval = Rval * p;
float tmp = Math.round(Rval);
return (float) tmp / p;
}
请帮忙。
任何帮助将不胜感激..
谢谢
