现在直播啊 网红这么火、好多互联网公司打直播的主意、好捞一点投资
有直播那么肯定离不开弹幕、现在时下最流行的第三方库是Bilibili
好东西要分享 上网址

但是这种弹幕适合免费全屏刷的那种弹幕、如果是需要图文修改挺麻烦 需要canvas来画、这个我也是实现了、有过想了解可以私信我
保证不丢失 不叠加、
此library只满足两种、要不就丢失不叠加 要不就不丢失 叠加、那么我就考虑使用动画
废话少说 上动态图
那么我们先说一下思路、
动画首先要有动画通道、那么通过自定义控件封装成通道、
通道关键是一个属性一个方法
isRunning;
startAnimation()
isRunning默认是false、在动画监听 start设置为true end设置为false
写一个一个danmuManager 管理类
通过mqtt或者是其他即时通讯的方法获取到弹幕、获取到弹幕后、
首先将danmuentity存放到Queque（队列）中
我们可以looperDanmu
循环所有的通道、判断通道有没有在执行动画、有过有一个没有那么 调用通道的startAnimation（）
然后queue.poll(); 移除这个danmuentity
如果这么写的话、是不能保证所有的弹幕都不丢失、因为如果我们有三个通道、瞬间来了六条弹幕、
那么循环完毕只会展示三条弹幕、剩下的三条还存放在queue中、那么我们的触发点在哪里呢、
有的人通过timerthread来每个几秒获取一个、但是是耗资源的、
那么我们可以在通道上打主意、如果动画执行完毕、主动去执行 looperDanmu、如果queue中还有
danmuentity那么继续startAnimation。。。 这样就保证了不丢失不叠加
好了上代码
定义弹幕动作接口

item_live_danmu 自己定义成所需的样式
view.measure(-1, -1); 重新绘制、获取高宽、以便动画 fromx tox
DanmakuEntity 自己定义即可、
好了 我们继续创建管理类
