Android: I want to shake it Do I need to create a method and use an if statement to find if mAccel is greater than 0? package your.shake.namespace; import android.app.Activity; import android.content.Context; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.os.Bundle; import android.os.Vibrator;

问题 Apple annonced Shake API in iPhone SDK 3.0. I can not find any information regarding this new feature. Who knows about how to use it?

问题 i've found a shake effect in stackoverflow question (here) Code is like below; jQuery.fn.shake = function(intShakes, intDistance, intDuration) { this.each(function() { $(this).css("position","relative"); for (var x=1; x<=intShakes; x++) { $(this).animate({left:(intDistance*-1)}, (((intDuration/intShakes)/4))) .animate({left:intDistance}, ((intDuration/intShakes)/2)) .animate({left:0}, (((intDuration/intShakes)/4))); } }); return this; }; but i need a way to add a callback function (or any

问题 I have a layout (which extends a framelayout) with a gridview and an imageview. I scroll through the layout with an onTouchListener,.

问题 I try to detect a shake on my phone with the Shaken event from Accelerometer object. The accelerometer object is not null but when I shake the phone, it never go in the _accelerometer_Shaken event. public int shakeCount = 0; Accelerometer _accelerometer = Accelerometer.GetDefault(); public MainPage() { this.InitializeComponent(); if (_accelerometer != null) { _accelerometer.Shaken += _accelerometer_Shaken; } } async private void _accelerometer_Shaken(Accelerometer sender,

问题 I can get the phone to react to a shake, but what is the best way to tell that it has stopped shaking? 回答1: This example worked for me. At the very bottom of the page you'll see: if (!_shaking && CheckForShake(_lastReading, reading, ShakeThreshold) && _shakeCount >= 1) { //We are shaking _shaking = true; _shakeCount = 0; OnShakeDetected(); } else if (CheckForShake(_lastReading, reading, ShakeThreshold)) { _shakeCount++; } else if (!CheckForShake(_lastReading, reading, 0.2)) { _shakeCount = 0;
