具有 1k 对象列表的优化列表视图 [英] Optimized List view with 1k object list

问题描述

我想知道是否有任何优化的方法来创建一个包含超过 1k 个对象的适配器.我尝试了以下方法，但结果仍然不尽如人意.

I was wondering if there is any optimized way to create an adapter that holds more than 1k object in it. I have tried the following but still the results were not promising .

A.View holder pattern-它有帮助，但是当对象大小增加时它开始出现问题

A.View holder pattern-It helped but when the object size increased it started have issues

B.注意:我可以使用一个分页的 api 来传递定义数量的对象，但我没有在我的场景中对 Api 进行分页.

B.Note: I could have used a paginated api which passes a defined number of objects but I annot have paginated Api in my scenerio.

C.我的列表中确实有图片，但我已经处理好了.现在不是问题.

C.My list do have images in it but I have taken care of that.Its not a problem now.

让我知道实现适配器的任何新方法，该适配器可以在其中包含大量对象列表而不会出现任何问题.

Let me know of any new ways to achieve a adapter that can have a large number of object list in it without any issues.

推荐答案

据我所知，我使用了下面的一些结构

As far as I know, I use some structure below

• 使用 ViewHolder
• 不使用时不要创建新对象
• 优化布局层次结构

• 防止过度绘制

https://developer.android.com/tools/performance/debug-gpu-overdraw/index.html

• 在 ListView 中加载 ImageView:我正在使用通用图像加载器"并启用模式:滚动时停止加载图像

• Load ImageView in ListView: I am using "Universal Image Loader" and enable mode: stop load image when scrolling

优化ListView的getView(...)函数中的代码Adapter:尽量让代码清晰简洁，限制使用if{}其他{}

Optimize code in the getView(...) function of ListView Adapter: Try to make the code clear and short, restrictive use if{}else{}
