Android -- [SelfView] 多动画效果图片播放器

效果（录制的有点卡）

1. 引用：

xml 复制代码

    <com.nepalese.virgolib.widget.image.BaseImageView
        android:id="@+id/base_image"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

2. 接口：

java 复制代码

private BaseImageView baseImageView;
//绑定
baseImageView = findViewById(R.id.base_image);
//设置动画类型
baseImageView.setAnimType(type);
//设置图片资源
baseImageView.setImageResource(path);
