ParallaxImageView

跟随重力感应的视差3D效果ImageView，效果图如下：

引入

步骤一：

root目录中的 build.gradle 加入 jitpack repositories:

allprojects {
  repositories {
    ...
      maven { url 'https://jitpack.io' }
  }
}

步骤二：

添加 dependency，最新版本

dependencies {
  implementation 'com.github.shenguojun:ParallaxImageView:$latestVersion'
}

使用

步骤一：

在XML或代码中创建GravityImageView，由于我们需要预留一些空间来进行左右晃动，其中scale参数表示图片放大的倍数。图片将按照这个比例进行放大，并且在上下左右晃动的时候展示出放大后被遮挡的部分。

<com.shengj.parallaximageview.GravityImageView
    android:id="@+id/image1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:scale="1.25"/>

步骤二：

在使用的Activity或者Fragment中注册GravitySensor并设置回调，GravitySensor将根据页面生命周期对传感器进行暂停。

// 注册声明周期以及传感器回调
lifecycle.addObserver(GravitySensor(this).also {
    it.listener = this
})

步骤三：

将传感器的回调直接设置给GravityImageView，其中x, y是表示跟重力方向一致，-x, -y表示跟重力方向相反

override fun onGravityChange(x: Float, y: Float) {
    binding.image1.onGravityChange(x, y)
    binding.image3.onGravityChange(-x, -y)
}

就这样我们就完成了一个随着重力作用而晃动的视差图了！
