片段显示和活动生命周期

Question

I thought that when I call

fragment.show(getSupportFragmentManager(), tag);

the activity were to PAUSED state by the calling of the onPause() method. But debugging the project I discovered that no lifecycle method is called. I was planning the flow to use the onPause() and onResume() methods when I call and dismiss a fragment, but it is confusing me. Can someone help me please?

Some observations regarding the show() method:

• It belongs to a DialogFragment ( link );

• It is only described by a fragment transaction (does not affect activity into enter onPause() state):

  public void show(FragmentManager manager, String tag) { mDismissed = false; mShownByMe = true; FragmentTransaction ft = manager.beginTransaction(); ft.add(this, tag); ft.commit(); }
