CanEffect
android效果库，阴影效果、水纹效果、波纹效果、圆形显示过渡效果等。
##添加依赖
compile 'com.canyinghao:caneffect:1.0.3'
使用方式
1. 实现方法
CanEffect是一个效果库，兼容至sdk11。很多效果都是继承FrameLayout，通过重写draw方法，画图绘制的。圆形显示过渡的效果，在sdk21及以上可使用系统自带的效果，以下是通过drawChild绘制的，但包装成了与系统相似的方法，用法一致。
public final class ViewAnimationUtils {
public static Animator createCircularReveal(View view, int centerX, int centerY, float startRadius, float endRadius) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
return android.view.ViewAnimationUtils
.createCircularReveal(view, centerX, centerY, startRadius, endRadius);
} else {
return CanCircularRevealLayout.Builder.on(view)
.centerX(centerX)
.centerY(centerY)
.startRadius(startRadius)
.endRadius(endRadius)
.create();
}
}
}
2. 使用方法
其它的阴影效果、水纹效果、波纹效果，使用方法如出一辙。
一些使用中的坑：
1.不要给CanRippleLayout、CanWaterWaveLayout添加点击或长按事件，不然它的子view接受不到事件。
2.如果使用了CanAdapter库，并且使用的是CanRVAdapter类，不要将CanRippleLayout、CanWaterWaveLayout放在item的最外层，CanRVAdapter的item的最外层view默认给了一个点击一个长按事件。
