我发现的唯一文件是:
MyFragment fragment = (MyFragment) getSupportFragmentManager().findFragmentById(R.id.fragment);
但是,由于分裂现象在“观点”中出现,我没有id。
List<Fragment> fragments = new Vector<Fragment>();
fragments.add(Fragment.instantiate(this, Fragment1.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment2.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment3.class.getName()));
成就

但请注意,如果你依赖<代码>。 FragmentPagerAdapter or FragmentStatePagerAdapter 持有您的碎片,某一指数的碎块可能不存在,要么是因为该指数尚未建立,要么已被抛弃,以尽量减少记忆消耗。
(BTW, see 为什么 Java/病媒类被认为过时或过时?在<条码>上更进一步。
