解决方式:减少布局嵌套层数,特别是用到类似tabHost,ViewPager的控件时,要考虑到最底层的 activity 的

contentView的布局,尽量简化,多用RelativeLayout替代LinearLayout

同样再优化列表滑动效率的时候,简化item布局也能带来巨大的体验提升


二,函数调用层级太多导致的 java.lang.StackOverflowError,如死循环,递归等

StackOverflowError是由于当前线程的栈满了  ,也就是函数调用层级过多导致。

比如死递归。

如:

  public String homePage(){
  this.findAllNews();
   return "shouye";
 }

 

public String findAllNews(){
   List newslist= hotnewsService.findAll();
   HotnewsDto  hotnews= (HotnewsDto) newslist.get(0);//得到第一条新闻
   String content=hotnews.getContent();
   String subcontent=content.substring(0, 80);//截取这条新闻信息内容在首页部分显示
   super.setRequestAttribute("hotnews", hotnews);
   super.setRequestAttribute("newslist", newslist);
   super.setRequestAttribute("subcontent", subcontent);
   return homePage;

   }

  如红色标记处,这样子调用的方法,相当于一个无限循环了!

解决办法:

  我习惯将 findAllNews方法的返回值设为 void 即可
