片段，onPause（）在onResume后调用（）

在我的应用程序中我有一个活动与一个容器布局的片段。在活动的片段，onPause（）在onResume后调用（）

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    Logger.enable(); 
    setContentView(R.layout.activity_main); 

    FragLobby fragLobby = (FragLobby)getSupportFragmentManager().findFragmentByTag(FragLobby.debugTag); 
    if(fragLobby==null) fragLobby = new FragLobby(); 
    FragmentHelper.replaceSupportFragment(this, fragLobby, R.id.llMain, false, FragLobby.debugTag); //helper method, replaces the fragment in a container, false = don't add to back stack 


    Logger.log(debugTag, "onCreate"); 
}

我添加碎片FragLobby到该容器布局。

在FragLobby的

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

    this.root = inflater.inflate(R.layout.frag_lobby, container, false); 

    FragPlayerInfo fragPlayerInfo = (FragPlayerInfo)this.getChildFragmentManager().findFragmentByTag(FragPlayerInfo.debugTag); 
    if(fragPlayerInfo==null) fragPlayerInfo= new FragPlayerInfo(); 
    FragmentHelper.replaceSupportFragmentInFragment(this, fragPlayerInfo, R.id.rlPlayerInfo, false, FragPlayerInfo.debugTag); 

    FragLobbyInfo fragLobbyInfo = (FragLobbyInfo)this.getChildFragmentManager().findFragmentByTag(FragLobbyInfo .debugTag); 
    if(fragLobbyInfo==null) fragLobbyInfo= new FragLobbyInfo(); 
    FragmentHelper.replaceSupportFragmentInFragment(this, fragLobbyInfo, R.id.rlLobbyInfo, false, FragLobbyInfo .debugTag); //uses childfragmentmanager 


    Logger.log(debugTag, "onCreateView"); 
    return this.root; 
}

辅助功能

public static void replaceSupportFragment(Context ctx, android.support.v4.app.Fragment newFragment, int root, boolean addToBackstack, String tag) { 

android.support.v4.app.FragmentManager fman = ((android.support.v4.app.FragmentActivity) ctx).getSupportFragmentManager(); 
android.support.v4.app.FragmentTransaction ftrans = fman.beginTransaction(); 
ftrans.setCustomAnimations(R.anim.fade_in, R.anim.fade_out,R.anim.fade_in, R.anim.fade_out); 
if(addToBackstack) ftrans.addToBackStack(tag); 
ftrans.replace(root,newFragment,tag); 
ftrans.commit(); 
} 

public static void replaceSupportFragmentInFragment(android.support.v4.app.Fragment currentFragment, android.support.v4.app.Fragment newFragment, int root, boolean addToBackstack, String tag) { 

android.support.v4.app.FragmentManager fman = currentFragment.getChildFragmentManager(); 
android.support.v4.app.FragmentTransaction ftrans = fman.beginTransaction(); 
ftrans.setCustomAnimations(R.anim.fade_in, R.anim.fade_out,R.anim.fade_in, R.anim.fade_out); 
if(addToBackstack) ftrans.addToBackStack(tag); 
ftrans.replace(root,newFragment,tag); 
ftrans.commit(); 
}

我其他两个片段添加到我的FragLobby，使用getChildFragmentManager（）。当我运行该程序，我会在启动时以下的生命周期...

它重新开始，只是被立即销毁。为什么会这样，以及可以做些什么呢？

谢谢:)

请打电话给'FragmentManager.enableDebugLogging（true）;'看看日志，你会看到所有的交易。请粘贴在这里。我们还需要帮助函数的代码，有些东西可能在那里。 – Delyan

@Delyan我添加了一些日志，甚至更多的辅助功能的代码，谢谢你的阅读:) – ElDuderino

嗯......是的......我修好了。 – ElDuderino

我其实只是通过创建一个新的项目，并与之前完全相同千方百计解决这个问题。现在日志输出如下：
