java - 如何使抽屉菜单链接到 Android Studio 中的其他 fragment

Question

我没有使用来自 android studio 的标准抽屉，但我正在使用 SlidingPanelLayout 创建抽屉(我根据本教程 https://nganthony.github.io/2016/01/24/implementing-android-mini-navigation-drawer.html 制作)

我的抽屉运行良好，但我不知道如何将按钮链接到另一个 fragment

我用这个方法调用标准抽屉里的fragment

if (id == R.id.nav_sms) {
            SMSFragment smsFragment = new SMSFragment();
            FragmentManager manager = getSupportFragmentManager();
            manager.beginTransaction().replace(
                    R.id.layout_main,
                    smsFragment,
                    smsFragment.getTag()
            ).commit();

Answer 1

覆盖 MasterFragment.java 上 ListFragment 的 onListItemClick() 方法。喜欢

public class MasterFragment extends ListFragment {

    public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_master, container);

        setListAdapter(new MenuListAdapter(R.layout.row_menu_action_item, getActivity(), MenuActionItem.values()));
        return view;
    }

@Override
        public void onListItemClick(ListView l, View v, int position, long id) {
            super.onListItemClick(l, v, position, id);

            if(position == 0){
                SMSFragment smsFragment = new SMSFragment();
                FragmentManager manager = getSupportFragmentManager();
                manager.beginTransaction().replace(
                        R.id.layout_main,
                        smsFragment,
                        smsFragment.getTag()
                ).commit();
            }
        }
}
