Android的加载动画AVLoadingIndicatorView
项目地址：
https://github.com/81813780/AVLoadingIndicatorView
首先，在 build.gradle.中添加；
dependencies { compile 'com.wang.avi:library:2.1.3' } 然后在xml中使用；
也可以通过代码显示或者隐藏；
void startAnim(){ avi.show(); // or avi.smoothToShow(); } void stopAnim(){ avi.hide(); // or avi.smoothToHide(); } QuantityView 类似购物车数量调节：
效果图：
