Question

我在我的活动中创建了滑块菜单，其中包含11个选项。当我点击任何选项时，它会切换到相应的片段。我只有一个片段有问题。片段打开很好但是当我点击三行时滑块菜单的选项，菜单没有打开。这个问题不存在于任何其他片段中，因为滑块菜单对其他片段打开正常。我发布了存在问题的片段代码。

PhotosFragment.java

public class PhotosFragment extends Fragment implements ActionBar.TabListener  {
    private FragmentActivity myContext;
    private ViewPager viewPager;
    private TabsPagerAdapter mAdapter;
    private ActionBar actionBar;
    // Tab titles
    private String[] tabs = { "IBL Tweets", "Fans Updates", "My Updates" };


        public PhotosFragment(){}
        @Override
        public void onAttach(Activity activity) {
            myContext=(FragmentActivity) activity;
            super.onAttach(activity);
        }


        public void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setHasOptionsMenu(true);
        }
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

            View rootView = inflater.inflate(R.layout.fragment_photos, container, false);
            viewPager = (ViewPager)rootView.findViewById(R.id.pager);
            actionBar =getActivity().getActionBar();
            mAdapter = new TabsPagerAdapter(myContext.getSupportFragmentManager());

            viewPager.setAdapter(mAdapter);
            actionBar.setHomeButtonEnabled(false);
            actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);        

            // Adding Tabs
            for (String tab_name : tabs) {
                actionBar.addTab(actionBar.newTab().setText(tab_name)
                        .setTabListener(this));
            }

            /**
             * on swiping the viewpager make respective tab selected
             * */
            viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

                @Override
                public void onPageSelected(int position) {
                    // on changing the page
                    // make respected tab selected
                    actionBar.setSelectedNavigationItem(position);
                }

                @Override
                public void onPageScrolled(int arg0, float arg1, int arg2) {
                }

                @Override
                public void onPageScrollStateChanged(int arg0) {
                }
            });
            return rootView;
        }
        @Override
        public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
            // TODO Auto-generated method stub
            super.onCreateOptionsMenu(menu, inflater);
            inflater.inflate(R.menu.main2, menu);
        }



        @Override
        public void onTabSelected(Tab tab, FragmentTransaction ft) {
            // TODO Auto-generated method stub
            viewPager.setCurrentItem(tab.getPosition());
        }



        @Override
        public void onTabUnselected(Tab tab, FragmentTransaction ft) {
            // TODO Auto-generated method stub

        }



        @Override
        public void onTabReselected(Tab tab, FragmentTransaction ft) {
            // TODO Auto-generated method stub

        }

    }

Answer 1

问题应该在

行

actionBar.setHomeButtonEnabled(false);

它使ActionBar图标无法点击，删除它并重试或放入

 actionBar.setHomeButtonEnabled(true);

代替

滑块菜单的三行选项对一个片段不起作用
