这是我的应用程序(带有片段):
在左侧有一个列表视图供您选择。
如果选择了其中一个,则右侧将加载片段并将选项卡添加到ActionBar。
这里有一个代码:

import java.util.ArrayList;

import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.ActionBar.Tab;
import com.actionbarsherlock.app.SherlockFragment;
import com.actionbarsherlock.app.SherlockFragmentActivity;

public class SpieleUndTabelleFragment extends SherlockFragment
{
    ViewPager mViewPager;
    TabsAdapter mTabsAdapter;

    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
    {
        ActionBar bar = getSherlockActivity().getSupportActionBar();
        bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        bar.setHomeButtonEnabled(true);

        mViewPager = new ViewPager(getSherlockActivity());
        mViewPager.setId(R.id.pager);

        mTabsAdapter = new TabsAdapter(getSherlockActivity(), mViewPager);

        mTabsAdapter.removeAllTabs();
        mTabsAdapter.addTab(bar.newTab().setText("Alle Spiele"), Spiele.class, null);
        mTabsAdapter.addTab(bar.newTab().setText("Tabelle"), Tabelle.class, null);

        return mViewPager;
    }

    public static class TabsAdapter extends FragmentPagerAdapter implements ActionBar.TabListener, ViewPager.OnPageChangeListener
    {
        private final Context mContext;
        private final ActionBar mActionBar;
        private final ViewPager mViewPager;
        private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>();

        static final class TabInfo
        {
            private final Class<?> clss;
            private final Bundle args;

            TabInfo(Class<?> _class, Bundle _args)
            {
                clss = _class;
                args = _args;
            }
        }

        public TabsAdapter(SherlockFragmentActivity activity, ViewPager pager)
        {
            super(activity.getSupportFragmentManager());
            mContext = activity;
            mActionBar = activity.getSupportActionBar();
            mViewPager = pager;
            mViewPager.setAdapter(this);
            mViewPager.setOnPageChangeListener(this);
        }

        public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args)
        {
            TabInfo info = new TabInfo(clss, args);
            tab.setTag(info);
            tab.setTabListener(this);
            mTabs.add(info);
            mActionBar.addTab(tab);
            notifyDataSetChanged();
        }

        public void removeAllTabs()
        {
            mActionBar.removeAllTabs();
            notifyDataSetChanged();
        }

        @Override
        public int getCount()
        {
            return mTabs.size();
        }

        @Override
        public Fragment getItem(int position)
        {
            TabInfo info = mTabs.get(position);
            return Fragment.instantiate(mContext, info.clss.getName(), info.args);
        }

        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels)
        {
        }

        public void onPageSelected(int position)
        {
            mActionBar.setSelectedNavigationItem(position);
        }

        public void onPageScrollStateChanged(int state)
        {
        }

        public void onTabSelected(Tab tab, FragmentTransaction ft)
        {
            Object tag = tab.getTag();
            for (int i = 0; i < mTabs.size(); i++)
            {
                if (mTabs.get(i) == tag)
                {
                    mViewPager.setCurrentItem(i);
                }
            }
        }

        public void onTabUnselected(Tab tab, FragmentTransaction ft)
        {
        }

        public void onTabReselected(Tab tab, FragmentTransaction ft)
        {
        }
    }

}

Spile和Tabelle类加载到片段中,然后像我想要的那样运行。
如果我点击一个类别(左边的片段),右边的spiele和tabelle calss标签就会加载并运行。
但是,如果我再次单击左侧的其他类别,actionbar中的选项卡将被删除并加载新的选项卡。但这是我的问题。
泰贝尔和斯皮尔标签不会再加载!我总是一页空白!因为to类不再加载…
下面是我用标签刷新正确片段的代码:
SpieleUndTabelleFragment fragment = new SpieleUndTabelleFragment();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.item_detail_container, fragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.commit();

有人能帮我吗?!
谢谢您!

我使用getFragmetManager()是因为我有一个带内部类的setOnItemListener()。如果我想使用getSupportFragmentManager()eclipse,就说它不支持它。
以下是该类中onCreateView()的代码:
View view = inflater.inflate(R.layout.waehle_mannschaft, container, false);

    ListView myList = (ListView) view.findViewById(R.id.list);

    myList.setDivider(null);

    final String[] listContent = {"News", "Gästebuch", "Herren 1", "Herren 2", "Herren 3", "Damen 1", "Damen 2", "männl. A", "männl. B1", "männl. B2", "männl. C", "männl. D", "E-Jugend"};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(view.getContext(), android.R.layout.simple_list_item_1, listContent);
    myList.setAdapter(adapter);

    final View v2 = view;
    myList.setOnItemClickListener(new AdapterView.OnItemClickListener()
    {
        public void onItemClick(AdapterView av, View v, int position, long id)
        {
            Toast.makeText(v2.getContext(), listContent[position], Toast.LENGTH_LONG).show();

            if(twoPanels)
            {
                SpieleUndTabelleFragment fragment = new SpieleUndTabelleFragment();
                FragmentTransaction ft = getFragmentManager().beginTransaction();
                ft.replace(R.id.item_detail_container, fragment);
                ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
                ft.commit();
            }
            else
            {
                Intent myIntent = new Intent(v2.getContext(), SpieleUndTabelleActivity.class);
                startActivity(myIntent);
            }
        }
    });

    return view;

斯皮尔此时一片空白。tabelle显示基本tabelle。如图所示:
我再说一遍。当我第一次在左边的片段上选择一个项目时,它会做我想做的事情。但是如果第二次点击verein+0-punkte消失,它是一个空白页…因为tabelle不再加载…

最佳答案

我认为问题在于,第二次加载时不会调用onCreateView,因为它已经创建好了。
移动附加片段的代码
onActivityCreated()
