有一个包含5个片段的活动(向导)。
StartFrag -(start)-> Frag1 -(next)-> Frag2 -(next)-> SubmitFrag
-(submit)-> SuccessFrag.
在成功片段上点击SubmitMore按钮后,我想从后台删除Frag1,Frag2和SubmitFrag并返回StartFrag。怎么做?

你可以试试这个
FragmentManager fm = getFragmentManager();
int count = fm.getBackStackEntryCount();
for(int i = 0; i < count; ++i) {
fm.popBackStack();
}

你可以试试这个
FragmentManager fm = getFragmentManager();
FragmentTransaction ft=fm.beginTransaction();
ft.add(R.id.group,startFrag,"");
ft.addtoBackStack("startFrag");
ft.commit();
enter code here
// add other 4 fragments here
when you want to go startFrag on click of some button you can try below code.
fm.popBackStack("startFrag",0);
//where startFrag is the tag which you specify when you called
//addtoBackStack("startFrag")
