拋出：IllegalArgumentException：未找到ID視圖 - 應用上重啓

Question

我的應用程序是使用片段和V4支持片段經理建。該應用程序運行良好，從啓動和實際上我不能自己重新創建這個錯誤，所以原則上我的XML的結構是好的。然而，我的崩潰報告顯示，很多用戶在返回到應用程序時發生崩潰，在暫停後恢復。我得到：

IllegalArgumentException: No view found for id 0x7f06002d 

請參閱我的XML在下面。報告爲未找到的ID可能會有所不同，它可以是任何嵌套的RelativeLayouts。爲什麼這些觀點隨機消失/未找到？

Answer 1

// try this way 
1. when you gave other layout reference like android:layout_above="@+id/bottomFragmentLayout" so here "+" sign removed from reference "+" is for new id declaration so we not declare new id but just gave already define id reference. 
2. in your xml define bottom layout at last and try using this layout id before bottom layout declaration that y it's not finding such kind of layout so you have decalre first layout then gave reference as another layouyt which i correct in my ans.
