Android 分享一个流量显示界面

波形效果有几种不同的呈现形式，比如从中间向四周散开的波形，也就是熟知的水涟漪；还有上下波动的曲线，像五线谱等。英文中可以称作Wave或者Ripple，所以暂且叫它们WaveView、WaveLayout、RippleView、RippleLayout，接下来开始实现这些效果。 首先看一下Solo 火爆足球动态壁纸， Android 分享一个流量显示界面_第1张图片
下面中间的按钮就是一个波形按钮，它会不断地向四周辐射，由于是静态图，如果想体验真实效果可以另行下载。这种效果的实现思路是不断绘制圆形，当然半径也要不断变化，透明度也是一样。代码如下： [html] view plain copy
