这是从backstack得到的片段，再次拨打onCreateView（） [英] The fragment which is got from backstack, call onCreateView() again

问题描述

请帮我解决我的问题。

我 MainActivity 用的FrameLayout。我想更换一些碎片进入的FrameLayout。现在我encounering一个问题，它是：

I have MainActivity with a framelayout. I want to replace some fragments into the framelayout. Now I am encounering an issues, it's:

1）我创建并把片段A至的FrameLayout。片段一个名为 onCreateView ...等。

1) I created and put fragment A to framelayout. Fragment A called onCreateView...etc.

2）然后我创建并把B片段布局......片段A被提上backstack并呼吁的onPause（）（不叫 onDeattach（），的onDestroy ...）

2) Then I created and put fragment B to layout... Fragment A was put on backstack and it called onPause() (not called onDeattach(), onDestroy...)

3）I pressed后退按钮。片段A从backstack了，但它叫 onCreateView（）一次。这个动作让我的应用程序有一些其他的问题。

3) I pressed back button. Fragment A was got from backstack, but it called onCreateView() again. This action make my app has some another issues.

所以我的问题是如何在碎片中的存储backstack，它不重建视图。

So my question is how to store fragment A in backstack and it don't recreate view.

这是被用来改变片段的方法：

This's the method that was used to change fragment:

public static void setContent(FragmentManager managerFragment, Fragment detailFragment) {
    if (managerFragment != null) {
        if(lastFragment==null && detailFragment instanceof HomeVer3Fragment ||
                (lastFragment!=null && detailFragment instanceof HomeVer3Fragment && lastFragment instanceof HomeVer3Fragment)){
            return;
        }
        String tag=detailFragment.getClass().getName();
        managerFragment.popBackStackImmediate(tag, FragmentManager.POP_BACK_STACK_INCLUSIVE);
        FragmentTransaction ft = managerFragment.beginTransaction();
        ft.replace(R.id.content_frame, detailFragment);
        ft.addToBackStack(tag);
        ft.commit();
        lastFragment = detailFragment;
    }
}

感谢和抱歉，我不好的问题，我的英语不是很好。

Thank and sorry for my bad question, my english is not well.

至于你重装（我假设），那么你可以做一些下述事情的问题：

As far your problem of reloading ( I assume ) you can do some thing like undermentioned:

（1）启动一个布尔值，说

(1) Initiate a Boolean value say

boolean android_hacker = false;

（2）现在说ü需要获取数据，并使用列表视图的一些看法。现在，在这个阶段集中android_hacker = TRUE;你已经获取的所有数据后。

(2) Now say U need to fetch data and create some view using list view. Now at this stage set "android_hacker = true;" after you have fetched all data.

（3）现在U时再回来相同的片段说：碎裂，然后点击OnCreateView检查值提到的。

(3) Now when U again come back to same fragment say "FragmentA" then check value on OnCreateView as mentioned ..

if(android_hacker != true){
        new GoAsyncTask().execute();
        }else{
// Perform stuff U need
}

就是这样。希望它可以帮助一些一

That's it. Hope it helps some one
