应用程序必须拖动 Tab 、 Tab A 和 Tab B 都延伸了块块。现在我的问题是, 当我点击 Tab B 列表项目时, 标签中应该使用一个新的块 C 。有了下面的代码, 我可以调用 Fragment C, 但不在标签内。

Intent intent = new Intent();
intent.setClass(getActivity(), C.class);
startActivity(intent);

当我使用活动时, 我就能通过活动小组来解决问题。

Answer 1

在点击列表项目上使用此代码尝试

private void stackAFragment() {
            Fragment f;
            f = new MedicationOrderFragment();
            FragmentTransaction ft = getFragmentManager().beginTransaction();
            ft.replace(R.id.main_details_fragment_container, f);
            ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
            ft.addToBackStack(null);
            ft.commit();
        }

试图重塑您的碎片 :

protected void replaceDataFragment(Fragment fragment){
    android.app.FragmentTransaction ftr = getFragmentManager().beginTransaction();
    ftr.replace(R.id.data<id of your fragment layout>, fragment);
        ftr.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
        ftr.commit();   
    }

Answer 3

With this code you can just start a new activity using intents. Try to use this in your fragment:

getSupportFragmentManager().beginTransaction().replace(
R.id.my_container_in_xml, new MyFragment(), 0).commit();
