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:id="@+id/activity_main"
 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:id="@+id/img_up"
 android:layout_width="match_parent"
 android:layout_height="0dp"
 android:layout_weight="1"
 android:background="@mipmap/shake_logo_up"
 />
 <ImageView
 android:id="@+id/img_down"
 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>
