android摇一摇实现(仿微信)

这个demo模仿的是微信的摇一摇,是一个完整的demo,下载地址在最下面.下面是demo截图:







步驟:

1.手机摇动监听,首先要实现传感器接口SensorEventListener.

/**开始重力传感器的检测*/
public void start() {
// 获得传感器管理器
SensorManager sensorManager = (SensorManager) mContext.getSystemService(Context.SENSOR_SERVICE);
if (sensorManager != null) {
// 获得重力传感器
sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
}
// 注册
if (sensor != null) {
sensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_GAME);
}
}

2.启动手掌开合动画,这个手掌其实是上下两部分组成的,分别开启一个上下垂直动画.

/** 摇一摇手掌上部分动画 */
public AnimationSet getUpAnim(Handler handler) {
AnimationSet animup = new AnimationSet(true);
TranslateAnimation mytranslateanimup0 = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF,
-0.8f);
mytranslateanimup0.setDuration(OPEN_TIME);
mytranslateanimup0.setAnimationListener(getLineVisibleListener(handler));

TranslateAnimation mytranslateanimup1 = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF,
+0.8f);
mytranslateanimup1.setDuration(CLOSE_TIME);
mytranslateanimup1.setStartOffset(OFFSET_TIME);
mytranslateanimup1.setInterpolator(new AccelerateInterpolator(1));
mytranslateanimup1.setAnimationListener(getLineGoneListener(handler));

animup.addAnimation(mytranslateanimup0);
animup.addAnimation(mytranslateanimup1);
return animup;
}

/** 摇一摇手掌下部分动画 */
public AnimationSet getDownAnim() {
AnimationSet animdn = new AnimationSet(true);
TranslateAnimation mytranslateanimdn0 = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF,
+0.8f);
mytranslateanimdn0.setDuration(OPEN_TIME);
TranslateAnimation mytranslateanimdn1 = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF,
-0.8f);
mytranslateanimdn1.setDuration(CLOSE_TIME);
mytranslateanimdn1.setStartOffset(OFFSET_TIME);
mytranslateanimdn1.setInterpolator(new AccelerateInterpolator(1));
animdn.addAnimation(mytranslateanimdn0);
animdn.addAnimation(mytranslateanimdn1);
return animdn;
}

3.结果页动画,重新摇一摇时,也会启动一个动画将结果页移动到最下方然后消失.就跟微信摇到了人以后,弹出的个人信息卡一样.
