片段寻呼机适配器和事务替换

Question

我有6个片段和一个主要活动。当我做Transaction .replace时我只能用4-6片段来做。如果我替换前3个片段（例如.replace(R.id.Frag3,fragmet)），当我进行交易时，我的游戏会崩溃。当我用片段3替换片段6时：

 @Override
 public Fragment getItem ( int arg0){
     switch (arg0) {
         case 0:
             return new Frag1();
         case 1:
             return new Frag2();
         case 2:
             return new Frag6();
         case 3:
             return new Frag4();
         case 4:
             return new Frag5();
         case 5:
             return new Frag3();
         default:
             break;
            }
     return null;
 }

Fragment 3 woks和Fragment 6崩溃所以它是第一个在.replace中崩溃游戏的case。 PLZ帮助！谢谢。

片段几乎相同。
