从ArrayList的对象，而LOOP - ANDROID [英] Select object from ARRAYLIST WITHOUT LOOP - ANDROID

问题描述

我要寻找可从ArrayList中选择的对象，如SQL库，其中命令。

I am looking for a library which can select object from ArrayList like SQL "where" command.

我有巨大的ArrayList（2000和20000之间），在我的项目，我不想写了，while循环每次..

I have huge arraylists (between 2000 and 20000) in my project and i don't want to write for,while loops every time..

我发现lambdaj，它是Java。

I found lambdaj and it is for Java.

我试图用lambdaj在我的Andr​​oid项目，但我不能这样做。

I tried to use lambdaj inside my Android project but i couldn't do it.

例如当我写                                                                                           名单，其中，销售与GT; sortedSales =排序（销售，上（Sale.class）.getCost（））;
  这个例子code在我的项目，日食都看不到的命令排序，...

For example when i write List<Sale> sortedSales = sort(sales, on(Sale.class).getCost());
this example code in my project, eclipse couldn't see "sort", "on" commands..

有没有想lambdaj其他库或者谁能告诉我，我该如何使用lambdaj在我的Andr​​oid项目？

Is there another library like lambdaj or can anyone tell me how can i use lambdaj in my android project ?

谢谢..

推荐答案

在番石榴库要比lambdaj更受欢迎，而且确实让你的避免获取，而循环使用preficates和过滤器的方法。

The Guava library is much more popular than lambdaj, and does allow you to avoid for, while loops by using preficates and filter methods.
