FrameAnimation

FrameAnimation是一个简洁流畅的高性能帧动画控件。 结合使用了TextureView和BlobCache，逐帧解析与绘制，避免了多帧的情况下使用Android原生AnimationDrawable带来的OOM和卡顿问题。

详细介绍文章：OOM？高性能帧动画FrameAnimation-TextureView和BlobCache

BlobCache算法可以查看：

  1. BlobCache算法详解
  2. BlobCache与DiskLruCache的读写对比

示例

添加配置

dependencies {
    ...
    implementation 'com.hewuzhao.frameanimation:frameanimation:1.0.1'
    ...
}

使用方法

动画资源图片，在/res/drawable下建立xxx.xml文件：

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:oneshot="false"
    app:maxBytes="524288000"
    app:maxEntries="100"
    app:version="1">

    <item
        android:drawable="@drawable/big_00"
        android:duration="60" />
    <item
        android:drawable="@drawable/big_01"
        android:duration="60" />
    <item
        android:drawable="@drawable/big_02"
        android:duration="60" />
    <item
        android:drawable="@drawable/big_03"
        android:duration="60" />
    <item
        android:drawable="@drawable/big_04"
        android:duration="60" />
    <item
        android:drawable="@drawable/big_05"
        android:duration="60" />
    <item
        android:drawable="@drawable/big_06"
        android:duration="60" />
    ....

</animation-list>
Attributes format describe
maxBytes integer BlobCache缓存的最大容量，单位：字节
maxEntries integer BlobCache缓存的资源个数
version integer BlobCache版本号

在你的xml布局文件中使用：

<com.hewuzhao.frameanimation.frameview.FrameTextureView
        android:id="@+id/frame_view"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:src="@drawable/big_animation_drawable"
        app:useCache="true" />
Attributes format describe
src reference res/drawable下的资源列表
useCache boolean 开关：是否使用BlobCache缓存

启动帧动画：

FrameTextureView.startWithFrameSrc(R.drawable.xxx);
