刪除高達「N」中的Android

Question

水平片段我做了什麼

所有片段添加一個在另一個之上，並添加到後退堆棧也

MainActivity - - - >Fragment_1 - >Fragment_2 - >Fragment_3 - >Fragment_4 - >Fragment_5 ------這可以去，直到片段N-Numbers

我所試圖做的：

Asume我在Fragment_5，然後我按下一個按鈕，我應該能夠通過刪除片段一路穿越回Fragment_2高達該水平

如何實現這一點;

Answer 1

你可以試試這個方法： fragmentManager.popBackStack（「The fragment of the fragment」，0）;

的方法的描述：

/** 
* Pop the last fragment transition from the manager's fragment 
* back stack. If there is nothing to pop, false is returned. 
* This function is asynchronous -- it enqueues the 
* request to pop, but the action will not be performed until the application 
* returns to its event loop. 
* 
* @param name If non-null, this is the name of a previous back state 
* to look for; if found, all states up to that state will be popped. The 
* {@link #POP_BACK_STACK_INCLUSIVE} flag can be used to control whether 
* the named state itself is popped. If null, only the top state is popped. 
* @param flags Either 0 or {@link #POP_BACK_STACK_INCLUSIVE}.
