Question

这是我的代码：

public class FragmentLifenews extends SherlockFragment {
    private ActionBar actionBar;
    private ViewPager viewPager;

    public FragmentLifenews() {

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.frag_life, container, false);
        viewPager = (ViewPager) view.findViewById(R.id.pager);
        viewPager.setOnPageChangeListener(onPageChangeListener);
        viewPager.setAdapter(new ViewPager1(getFragmentManager()));
        addActionBarTabs();

        return view;
    }

    private ViewPager.SimpleOnPageChangeListener onPageChangeListener = new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {
            super.onPageSelected(position);
            actionBar.setSelectedNavigationItem(position);
        }
    };

    private void addActionBarTabs() {
        getSherlockActivity().getSupportActionBar();
        getSherlockActivity().setSupportProgressBarVisibility(true);
        getSherlockActivity().setSupportProgressBarIndeterminate(true);
        String[] tabs = { "Tab 1", "Tab 2", "Tab 3" };
        for (String tabTitle : tabs) {
            ActionBar.Tab tab = actionBar.newTab().setText(tabTitle)
                    .setTabListener(tabListener);
            actionBar.addTab(tab);
        }
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    }

    private ActionBar.TabListener tabListener = new ActionBar.TabListener() {
        @Override
        public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
            viewPager.setCurrentItem(tab.getPosition());
        }

        @Override
        public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
        }

        @Override
        public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
        }
    };



public class ViewPager1 extends FragmentStatePagerAdapter {

    private final int PAGES = 3;

    public ViewPager1(FragmentManager actionBar) {
        super(actionBar);
    }

    @Override
    public Fragment getItem(int position) {
        switch (position) {
            case 0:
                return new Tab1Fragment();
            case 1:
                return new Tab2Fragment();
            case 2:
                return new Tab3Fragment();
            default:
                throw new IllegalArgumentException("The item position should be less or equal to:" + PAGES);
        }
    }

    @Override
    public int getCount() {
        return PAGES;
    }

FragmentLifenews是从SherlockFragment延伸的类。我想用ViewPager标签添加SherlockFragment，但我无法收到错误：

   com.locii.fragment.FragmentLifenews.onCreateView(FragmentLifenews.java:28) 
   viewPager.setOnPageChangeListener(onPageChangeListener);
   viewPager.setAdapter(new ViewPager1(getFragmentManager()));

请告诉我我做错了什么我改变getFragmentManager()代替getSupportActionBar()请建议我。

@SuppressLint（ “ResourceAsColor”）公共类MainActivity扩展了FragmentActivity实现 OnTabChangeListener，OnPageChangeListener {

MyPageAdapter pageAdapter;
private ViewPager mViewPager;
private TabHost mTabHost;

@Override

            this.mTabHost.newTabSpec("Tab5").setIndicator(
                    "",
                    getApplicationContext().getResources().getDrawable(
                            R.drawable.btn_more)));

    mTabHost.setOnTabChangedListener(this);

    setSelectedTabColor();
}

} 我在我的应用程序中使用tab主机并查看pager ...
