Android实现微信摇一摇功能

本文实例为大家分享了Android实现微信摇一摇功能的具体代码，供大家参考，具体内容如下

1、初始化界面

设置摇一摇界面的背景图片和摇动时的上下两半张图片

<?xml version='1.0' encoding='utf-8'?><RelativeLayout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:tools='http://schemas.android.com/tools' android: android:layout_width='match_parent' android:layout_height='match_parent' tools:context='com.example.yyy.MainActivity' android:background='@mipmap/shakehideimg_man2' > <LinearLayout android:layout_width='match_parent' android:layout_height='match_parent' android:orientation='vertical' > <ImageView android: android:layout_width='match_parent' android:layout_height='0dp' android:layout_weight='1' android:background='@mipmap/shake_logo_up' /> <ImageView android: android:layout_width='match_parent' android:layout_height='0dp' android:layout_weight='1' android:background='@mipmap/shake_logo_down' /> </LinearLayout></RelativeLayout>

2、Mainactivity - onCreate()

private ImageView imgDown; private ImageView imgUp; private SensorManager sensorManager; private SensorEventListener sensorEventListener; private Sensor accSensor; private AnimationSet upAnimationSet; private AnimationSet downAnimationSet; private SoundPool soundPool; private int soundId; private Vibrator vibrator; private boolean isYYY = false; /*1.初始化页面 2.初始化数据 * 3.监听加速度变化(触发条件) * 1.图片执行动画 * ***2.到服务器查询同一时间摇一摇的异性用户 * 2.播放音乐 * 3.振动 * **4.当你正在摇的时候(不能再摇动) * */ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); initData(); initEvent(); //注册监听 sensorManager.registerListener(sensorEventListener,accSensor,SENSOR_DELAY_NORMAL);}

3、初始化数据

private void initData() { //先获得传感器管理器 sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); //获得加速度传感器 accSensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); //获得振动器 vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); //初始化声音池 soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0); //初始化声音资源 soundId = soundPool.load(this,R.raw.awe,1); //初始化动画 upAnimationSet = new AnimationSet(true); TranslateAnimation upUpAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, -0.5f); upUpAnimation.setDuration(500); TranslateAnimation upDownAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, -0.5f, Animation.RELATIVE_TO_SELF, 0); upDownAnimation.setDuration(500); //down动画在up动画之后执行 upUpAnimation.setStartOffset(500); upAnimationSet.addAnimation(upUpAnimation); upAnimationSet.addAnimation(upDownAnimation); upAnimationSet.setDuration(1000); upAnimationSet.setStartOffset(200); //初始化动画 downAnimationSet = new AnimationSet(true); TranslateAnimation downUpAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0); downUpAnimation.setDuration(500); TranslateAnimation downDownAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0.5f); downDownAnimation.setDuration(500); //down动画在up动画之后执行 downDownAnimation.setStartOffset(500); downAnimationSet.addAnimation(downDownAnimation); downAnimationSet.addAnimation(downUpAnimation); downAnimationSet.setDuration(1000); downAnimationSet.setStartOffset(200); }

4、初始化事件 - 摇一摇

给加速度感应器设置监听① 设置摇一摇的触发条件② 播放动画③ 播放音乐④ 开启震动

private void initEvent() { sensorEventListener = new SensorEventListener() { /* * 当传感器的值发生变化时的回调 * */ @Override public void onSensorChanged(SensorEvent event) { //Log.i('AAA', 'onSensorChanged: '); //设置触发摇一摇的条件 //获得x,y,z方向的变化 float[] values = event.values; float valueX = values[0]; //空间中X的变化 float valueY = values[1]; //空间中Y的变化 float valueZ = values[2]; //空间中Z的变化 if(valueX > 15 || valueY > 15 || valueZ >15){//触发条件 if(!isYYY){ imgUp.startAnimation(upAnimationSet); imgDown.startAnimation(downAnimationSet); //播放音乐 soundPool.play(soundId,1,1,1,0,1); //振动 vibrator.vibrate(new long[]{200,400,200,400,200,400,200,400},-1); } } } /* *当传感器精度发生变化的回调 * */ @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { } }; upAnimationSet.setAnimationListener(new Animation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { isYYY = true; } @Override public void onAnimationEnd(Animation animation) { isYYY = false; } @Override public void onAnimationRepeat(Animation animation) { } });}

5、添加权限

<uses-permission android:name='android.permission.VIBRATE'></uses-permission>
