PopBackStack vs popBackStackImmediate

Fragment addToBackStack() and popBackStackImmediate() not

the reason why the popBackStack () and popBackStackImmediatly () is due to the fact that you didnt add that fragment (that you want to pop) to the backStack. In order to do this you have to make a call to addToBackStack () at the moment of making the transaction to add/replace your fragment The other type of tag is the BackStackRecord's name passed in to addToBackStack (). This name identifies a particular back stack record, which is a record of what occurred in a particular.. On a side note, popBackStack () has a popBackStackImmediate () counterpart, which performs similarly to commit () and commitNow (). The former is asynchronous, the latter is synchronous. Which one.. You can pass the fragment name as the parameter to addToBackStack(name) instead of Null. If you pass Null then you would not be able to use the method FragmentManager.popBackStackImmediate(String name, int flags); or popBackStack(String name, int flags); because the name was Null. So the popBackstack methods will not work

Managing the Fragment Back Stack

  1. popBackStack (String tag) pops transactions until the transaction with supplied 'tag'. popBackStack (String tag, int flag) pops till the transaction with mentioned 'tag' if flag is POP_BACK_STACK_INCLUSIVE, or else 0  can be used. popBackStack (int id, int flag) pops till the transaction with mentioned 'tag'
  2. FragmentManager, Like PopBackStack (), but performs the operation immediately inside of the call. PopBackStackImmediate (Int32, PopBackStackFlags) PopBackStackImmediate (popBackStackImmediate is slower than popBackStack in order to avoid performance issues use popBackStack where ever possible. - Faisal Naseer Apr 5 '18 at 7:47
  3. FragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE) is supposed to pop the entire back stack... I think the documentation for that is just wrong. != 0) { fragmentManager.popBackStackImmediate(); } } The above method loops over all the transactions in the backstack and removes them immediately one at a time. Note.

  5. Okay got it. so while moving to B -> C1 and B -> C2 don't add ' manager.popBackStack();' and also addToBackStack(null). @Kling Klang, well it does seem like a possible hack if I just remove C1 and C2 fragments from stack on back key. Even though this approach is non-intuitive and requires additional code for each case

PopBackStack (Int32, PopBackStackFlags) PopBackStack (Int32, PopBackStackFlags) Pop all back stack states up to the one with the given identifier. PopBackStack (String, PopBackStackFlags) PopBackStack (String, PopBackStackFlags) Pop the last fragment transition from the manager's fragment back stack difference between popBackStackImmediate vs popBackStack.

I still could not fix the issue through getBackStackEntryCount() and i solved my issue by making the main page a fragment too, so in the end i have an activity with a FrameLayout only; and all other fragments including the main page i inflate into that layout. This solved my issue Una manera es etiquetar el backstack y cuando se quiere borrar. mFragmentManager.popBackStack (myfancyname, FragmentManager.POP_BACK_STACK_INCLUSIVE); Donde el myfancyname debe coincidir con la cadena que utilizó con addToBackStack . P.ej popBackStack() will pop the back stack, but it won't perform the pop until slightly later - it posts a message to do it so you don't have to wait for a heavyweight operation to occur. popBackStackImmediate() does it right now, before the function returns. Its slower and can cause perf issues. Use the non-immediate version when possible. 0 as the second parameter means to use the default.

The many flavors of commit()

the reason why the popBackStack () and popBackStackImmediatly () is due to the fact that you didnt add that fragment (that you want to pop) to the backStack. In order to do this you have to make a call to addToBackStack () at the moment of making the transaction to add/replace your fragment. Share But you call popBackStack() on the getFragmentManager(). Then popBackStackImmediate can reverse the operation and it is working. I hope it solves the problem. I know it is an old post but I do encounter a similar problem and wish this update can help others. Below should be the correct order popBackStackImmediate() and its counterparts have variants that accept a back stack record name to pop the back stack to a particular state. Inclusive vs Exclusive

android - What is the meaning of addToBackStack with null

Transactions do not get added to back stack by default. An explicit call to addToBackStack (String tag) before committing it, would add it to BackStack. The 'tag' string would be an identifier of the transaction and can be used to refer back to it later. Reverse of this method is popBackStack () and its following variants On a side note, popBackStack() has a popBackStackImmediate() counterpart, which performs similarly to commit() and commitNow(). The former is asynchronous, the latter is synchronous. The former is. What documentation says for popBackStack(): Pop all back stack states up to the one with the given identifier. 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.. So after mFragmentManager.popBackStack(null, 0); your backstack is not empty until your event is completely processed

Popbackstackimmediate. difference between popBackStackImmediate vs popBackStack , popBackStackImmediate() will perform the popping commands immediately in the call. The results of which can be verified immediately after PopBackStackImmediate(Int32, PopBackStackFlags) PopBackStackImmediate(Int32, PopBackStackFlags) Like PopBackStack(Int32. 138. You can pop the fragment by name. While adding fragments to the back stack, just give them a name. fragmentTransaction.addToBackStack (fragB); fragmentTransaction.addToBackStack (fragC); Then in Fragment_C, pop the back stack using the name ie.. fragB and include POP_BACK_STACK_INCLUSIVE FragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE) is supposed to pop the entire back stack... I think the documentation for that is just wrong. != 0) { fragmentManager.popBackStackImmediate(); } } The above method loops over all the transactions in the backstack and removes them immediately one at a time. Note.

Step #2: Have D remove the fragments via FragmentManager. The hosting activity (D) is the one that knows what other fragments are in the activity (vs. being in other activities). Hence, in-fragment events that might affect the fragment mix should be propagated to the activity, which will make the appropriate orchestration moves

popBackStack() 和 popBackStackImmediate() 与 commit() 和 commitNow() 的情况是一样的。 最后来总结下该如何选择这些函数: 如果你需要同步提交 Fragment 并且无需添加到 堆栈 中,则使用 commitNow() popBackStack() popBackStackImmediate() popBackStack(int id/String name, int flags) popBackStackImmediate(int id/String name, int flags) PopBackStackState类 实现了 OpGenerator 接口,具体实现如下: 参数 records 用来存放出栈的 BackStackRecord; 参数 isRecordPop 用来存放相应 BackStackRecord 是否为出栈(显然为 true Teoría. Utilice el addToBackStack(tag:String):FragmentTransaction dentro de FragmentTransaction para marcar el punto al que desea regresar. Este método devuelve la instancia de FragmentTransaction para la habilidad de cadena.. A continuación, regrese con el popBackStackImmediate(tag:String,flag:int):void del FragmentManager.La etiqueta es lo que especificó antes popBackStack()是异步执行的,是丢到主线程的MessageQueue执行,popBackStackImmediate()是同步版本。 我们通过讲解Demo1来更清晰地了解回退栈的使用。功能如下:共有三个Fragment:F1, F2, F3,F1在初始化时就加入Activity,点击F1中的按钮跳转到F2,点击F2的按钮跳转到F3,点击F3. gerrit-git(pull vs checkout vs cherrypick)这是做什么用的? 版本控制-git是否忽略空文件夹? 版本控制-Git并在多个分支上工作; 我如何将git拉到特定分支? 取消跟踪并停止跟踪gi中的文件; 我将如何在Git中编写一个合并前的钩子? 如何获取匹配正则表达式的最后一个Git.
