在Android片段中未调用OnCreateView

Question

I have a listView on the left, and a nested fragment with checkBoxes on the right.

The checkBoxes are in an Arraylist declared globally. The ArrayList is created dynamically in the onCreateView method of the nestedFragment.

In the onPause method i save the checkboxes state.

The onclick listener of the listView, replaces the Fragments is this way:

 CheckNodesFragment checkNodesFragment = new CheckNodesFragment();

 FragmentTransaction fragmentTransaction = getChildFragmentManager().beginTransaction();


 fragmentTransaction.replace(R.id.child_fragmentB, checkNodesFragment);
 fragmentTransaction.commit();

Problem: When i click the Icarus or whatever listview item double times, the app crashes in the onPause() , since the onCreateView method making all initializations is not be called, but only onPause is called.

However, when i add and not replace the fragment all the lifecycles methods are called, and onCreateView() too, but when i add the fragment the screen's text becomes more bold with each add:

我发现了问题，发现替换片段时，第一个生命周期片段的调用是onPause方法，然后是onStop，onDestroyView等，考虑到这一点，我解决了我的问题。
