我已经把你的代码复制到我的项目里面了,toolbar我只需要部分的功能 所以能简单就简单 不需要的功能我都给删了 现在试着改改 有问题 问你哈

大神 我的recyclerview item有aretextview 但是当图片多的时候 滑动就会卡顿 请问对于图片的加载有没有优化的方法啊
from android-rich-text-editor.
贴Adapter代码来看看

查看下最新的AreTextView.java 或者 下面的代码。
使用 fromHtmlWithCache
代替 fromHtml
, 不过在你的Activity退出或其他合适的时机,需要调用 clearCache

现在不卡了,不过感觉这个只是一时的解决 不算是根本解决 因为是存到内存中 所以不能太多对象 。
from android-rich-text-editor.
你说的对。根本解决我也没有好的想法,我能想到的顶多是换成弱引用的缓存,毕竟图像要显示的话 他一定得占内存,用在list中更是如此,只要出了内存再往内存里加载,这个过程肯定就会慢。
上面的代码主要是缓存了 Spanned, 省去的是解析过程。
图片压缩性能方面没有太多研究,欢迎前来增强。

大神 我测试了下 我把 imageGetter里面的 Util.scaleBitmapToFitWidth(bitmap, Constants.SCREEN_WIDTH) 这段缩放的代码注释 然后滑动就没有卡顿了

👍 忽然很想看看把AreTextView放到RecyclerView里面是啥样。
from android-rich-text-editor.
最新版本已经解耦。欢迎查看,谢谢。
