java - fragment 内的 SlidingMenu

Question

我正在尝试将 SlidingMenu 包含在 Fragment 中。我想将 SlidingMenu 放在 fragment 中的原因是我的 viewPager 的页面之一将显示它。只是对如何扩展 fragment 感到困惑，因为其中一个示例扩展了 SlidingFragmentActivity。

 public class Activity A extends SlidingFragmentActivity {}

我一直在努力，

public class ResponsiveUIActivityE extends SherlockFragment{

    View rootView;
    private Fragment mContent;

       @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

           SlidingFragmentActivity2 sl = new SlidingFragmentActivity2();



           getActivity().setTitle("R.string.responsive_ui");
           LayoutInflater vi = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
           rootView = vi.inflate(R.layout.two_fragments, null, false);

        // check if the content frame contains the menu frame
            if (rootView.findViewById(R.layout.two_fragments) == null) {
                //sl.setBehindContentView(R.layout.two_fragments);
                sl.getSlidingMenu().setSlidingEnabled(true);
                sl.getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
                // show home as up so we can toggle


            } else {

            }

            // set the Above View Fragment
            if (savedInstanceState != null){
                mContent = getChildFragmentManager().getFragment(savedInstanceState, "mContent");
            if (mContent == null)
                mContent = new BirdGridFragment(0); 
            getChildFragmentManager()
            .beginTransaction()
            .replace(R.id.content_frame, mContent)
            .commit();

            // set the Behind View Fragment
            getChildFragmentManager()
            .beginTransaction()
            .replace(R.id.menu_frame, new BirdMenuFragment())
            .commit();

            // customize thse SlidingMenu
            SlidingMenu sm = sl.getSlidingMenu();
            sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
            sm.setShadowWidthRes(R.dimen.shadow_width);
            sm.setShadowDrawable(R.drawable.shadow);
            sm.setBehindScrollScale(0.25f);
            sm.setFadeDegree(0.25f);
            }

        return rootView;
       }
}

Answer 1

从上一个支持库版本开始，您可以使用标准 DrawerLayout .由于您现在正在实现它，我强烈建议您采用标准而不是使用外部库。

我看不出有任何理由不能在 ViewPager 中工作。

这里是 official tutorial .
