使用Eclipse变过Java的人肯定感觉Eclipse一点都不怎么智能,只有将一个类名完整的敲出来,然后加个点之后的方法属性才会出来。例如我们在Eclipse里面只有输入System,然后再加个点,n久之后才会显示出System类里面的属性及方法。

    其实这个我们可以自己设置的(本人使用的是英文版的3.3版本),过程为:先是选中菜单栏里的 windows->Preferences,然后选中 java节点 -> Editor->Content Assist  。如下图示:

找到Auto-Activation选项,在下面的Auto activation triggers for Java 右侧填冲框中默认为 . ,而且Eclipse默认为最多输入四个字母,这时候我们输入abcd,保存一下。

 

    下一步就是导出我们的偏好文件了,选择菜单栏的 File->Export->Gerneral->Preferences,选中Export all,点击 Browser 选择偏好文件的保存目录,要记住该目录,后面会用到。单击Finish,这时候我们便将偏好文件导出了,默认格式为 .epf。我们这样做的目的就是Eclipse限制了我们的修改,那么我们只能将设置偏好的文件先导出,然后手工修改以后再导入进来。

  

   Ps:留意到上图中的200了吗,其实那个就是智能框出现需要的延迟,单位是ms。当然你如果嫌200慢了,你可以将数值调小,当然快是有代价的,Eclipse当然会耗费系统更加多的资源了。设不设置都在于个人偏好啦。
