最小化应用上产生的请求，我尽量减少应用程序和崩溃的应用程序中间的onSaveInstanceState

Question

后无法执行此操作

我正在与改造一个异步请求，...

我的日志错误：

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

这就是我所说的，如果请求返回成功的方法：

ActivityUtils.replaceFragmentToActivityWithBackStack(getFragmentManager(), IncompleteStatusFragment.newInstance(mLogin.getCustomerId(), mCustomer, prospect, mLogin), R.id.container_login); 

有人能帮助我吗？

这很明显，如果你最小化应用程序，那么你将无法替换片段，因为你的应用程序没有焦点& throw java.lang.IllegalStateException。如果该标志为真，则应该在您的活动的onResume中维护一个标志&，然后替换该片段。

像

@Override 
public void onPause() { 
    mIsActivityVisible = false; 
} 

@Override 
public void onResume() { 
    mIsActivityVisible = true; 
    if(mShouldReplaceFragmentOnResume) { 
     mShouldReplaceFragmentOnResume = false; 
     // replace fragment 
    } 
} 

// On Success response 
onSuccessOfYourCall() { 
    if(mIsActivityVisible) { 
     //replace fragment 
    } else { 
     mShouldReplaceFragmentOnResume = true; 
    } 
}
