Android的碎片回到preSS [英] android fragment backpress

问题描述

我有4个片段，即A B C D。 现在，当我更多的从A到B，我添加了一个向后堆栈。 比我谨从B到C，而不增加回堆栈。 比我谨从C到D无添加备份堆栈。 现在回到preSS我重定向到一个。

I am having 4 fragments namely A B C D. Now When i more from A to B, I add A to back stack. than I move from B to C without adding to back stack. than I move from C to D without adding to back stack. now on back press I am redirected to A.

我再次重复，直到D和现在，当我回到preSS，它显示片段A和再次重定向我片段D和再次返回preSS，它退出应用程序。

Again I repeat till D and now when I back press, It displays fragment A and again redirects me to fragment D and on Back press again, it exits app.

我希望它像从D背面preSS它应该总是让我去A

I want it to be like On back press from D It should always get me to A

谁能帮助？

推荐答案

只是删除​​ super.onBack pressed（）; 从codeS

Just remove super.onBackPressed(); from your codes
