推荐答案

实际上非常简单:

假设您添加了这样的片段:

let's say you added the fragment like this:

fragmentTransac.add(R.id.content, fragA);

相反，您也将其添加有TAG

instead, you'll add it with a TAG too

fragmentTransac.add(R.id.content, new FragA(), "first");
// then the other
fragmentTransac.add(R.id.content, new FragA(), "second");

然后删除:

Fragment f = getFragmentManager().findFragmentByTag("first");
if(f!=null) fragmentTransac.remove(f);
fragmentTransac.commit();

快乐编码=]
