片段片段不要刷新 [英] Fragment in fragment do not refresh
问题描述
这是我的应用程序（带片段）：
在左侧有一个ListView，你可以选择。
如果你选择了一个右侧装入片段，并添加标签的动作条。
还有就是code为：
this is my app (with fragments): On the left side there is a ListView where you can choose. If you selected one the right side load a fragment and add Tabs to the ActionBar. There is the code for that:
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)
{
}
}
}
的免费游戏和Tabelle级加载到碎片，并运行像我想要的。
如果我点击一类的（左片段）与免费游戏和Tabelle-CALSS加载和运行正确的标签。
但是，如果我在左侧点击其他类别的第二时间在动作条的标签被删除，新的负载。但是，我的问题。
Tabelle和免费游戏的选项卡再次犯规负荷！我一直一个空白页！因为上课再次犯规负载...
The Spiele and Tabelle-Class load into the fragments and runs like i want. If i click of one category (of the left fragment) the right Tabs with Spiele and Tabelle-Calss loads and run. But if i click a second time of a other category on the left side the tabs in actionbar are removed and new one load. But there is my problem. Tabelle and Spiele-Tabs doesnt load again! I have always a blank page! because the to classes doesnt load again...
下面是code，我刷新右片段的标签：
Here is the code which i refresh the right fragment with the tabs:
SpieleUndTabelleFragment fragment = new SpieleUndTabelleFragment();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.item_detail_container, fragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.commit();
任何人可以帮助我吗？
谢谢！
Can anybody help me?! Thank you!

我用 getFragmetManager（），因为我有一个 setOnItemListener（）用内部类。如果我想使用 getSupportFragmentManager（）日食说doestnt支持。
这里是从 onCreateView（）从类code：
i use getFragmetManager() because i have a setOnItemListener() with inner-class. If i want to use getSupportFragmentManager() eclipse say it doestnt support it.
here is the code from onCreateView() from the class:
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;
免费游戏是在这个时候空。 Tabelle显示基本tabelle。喜欢的形象：
我再说一遍。我第一次在左侧选择片段的项目就做我想做的。但是，如果点击第二次＃社团组织+ 0 - Punkte消失，这是一个空白页...怎么一回事，因为tabelle再次不加载...
Spiele is blank at this time. Tabelle show a basic tabelle. Like the image: and i say it again. the first time i choose a item on the left fragment it do what i want. but if click a second time the # Verein + 0 - Punkte goes away and it is a blank page...beacuse tabelle dont load again...
推荐答案
我认为问题是， onCreateView 犯规得到第二次调用加载它，因为它已经是创建。
I think the problem is that onCreateView doesnt get called the second time you load it because it is already created.
移动code用于连接片段
Move the code for attaching the fragment
到 onActivityCreated（）
这篇关于片段片段不要刷新的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
