主要看这行：this.renderListRef[i].current.measure // undefined

我不会用ref去测量，用起来不可靠，还是每个都去onLayout最可靠

也没看懂你这个组件是要干什么，你可以参考我用reanimated做滚动组件，我猜你大概也是要写类似的东西？

事情大概是这样的，为了实现图文混排，并且需要换行，最常见的场景就是商品前加一个 「特惠」的标志或者双十一的标签，这可能是一个View组件或者是Image，后面跟着Text文本，然后设定超出显示 ...。我想做的就是把text每一个字符拆成独立的text，父元素flex-wrap: warp换行，最后利用onLayout计算超出的文字，然后将超出之前的最后三个字符转换为...
