GLES20Canvas.nDrawDisplayList 很慢
我有一个正在尝试显示的自定义视图，但是我看到它上面有一堆抖动。 一切都滚动缓慢，并且响应速度不及应有的水平。
我使用了 Traceview 并发现
GLES20Canvas.nDrawDisplayList
似乎需要花费大量时间来执行。
有什么帮助吗？
I have a custom view that I am trying to display, however I am seeing a bunch of jitter on it.
Everything scrolls slow and it isn't as responsive as it should be.
I used traceview and saw that
GLES20Canvas.nDrawDisplayList
seems responsible for taking a lot of time to execute.
Any help please?

如果您绘制很多，尤其是非常大的视图，则 GLES20Canvas.nDrawDisplayList 预计会占用很大一部分时间。
如果您在跟踪视图中看到这一点，答案是“减少绘制”
在我的特定问题中，我在大视图上绘制了一个大的 alpha 图层。

GLES20Canvas.nDrawDisplayList is expected to have a large portion of the time if you are drawing a lot, especially very big views.
If you are seeing this all over your traceview the answer is "DRAW LESS"
In my specific issue I was drawing a large alpha layer over large views.
