我有一个主类,它包含一个带有tabs和viewpager的actionbarsherlock
就是这样:
public class HSG_Handball extends SherlockFragmentActivity
{
ViewPager mViewPager;
TabsAdapter mTabsAdapter;
TextView tabCenter;
TextView tabText;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
mViewPager = new ViewPager(this);
mViewPager.setId(R.id.pager);
setContentView(mViewPager);
ActionBar bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mTabsAdapter = new TabsAdapter(this, mViewPager);
mTabsAdapter.addTab(bar.newTab().setText("Alle Spiele"), Spiele.class, null);
mTabsAdapter.addTab(bar.newTab().setText("Tabelle"), Tabelle.class, null);
}
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();
}
@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)
{
}
}
public boolean onCreateOptionsMenu(Menu menu)
{
SubMenu subMenu1 = menu.addSubMenu("Aktive");
subMenu1.add("Herren 1");
subMenu1.add("Herren 2");
subMenu1.add("Herren 3");
subMenu1.add("Damen 1");
subMenu1.add("Damen 2");
MenuItem subMenu1Item = subMenu1.getItem();
subMenu1Item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
SubMenu subMenu2 = menu.addSubMenu("Jugend");
subMenu2.add("männl. A");
subMenu2.add("weibl. A");
subMenu2.add("männl. B1");
subMenu2.add("männl. B2");
subMenu2.add("männl. C");
subMenu2.add("männl. D");
subMenu2.add("E-Jugend");
MenuItem subMenu2Item = subMenu2.getItem();
subMenu2Item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if(!item.getTitle().toString().equals("Active") || !item.getTitle().toString().equals("Jugend"))
{
new Spiele().FormatiereSpieleSeite(item.getTitle().toString());
}
return super.onOptionsItemSelected(item);
}
}
第二个类(Spiele)是一个带有自定义基本适配器的listfragment。 该课程看起来如此:
public class Spiele扩展了ListFragment {
String ligaId = "0";
SpieleAdapterFuerCustomList adapter;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.spiele, container, false);
List<String> dateAndSchiri = new ArrayList<String>();
dateAndSchiri.add("DATUM · Schiri 1 : Schiri 2");
dateAndSchiri.add("DATUM · Schiri 1 : Schiri 2");
dateAndSchiri.add("DATUM · Schiri 1 : Schiri 2");
List<String> heim = new ArrayList<String>();
heim.add("HSG Nieder-Roden");
heim.add("SG Bruchköbel");
heim.add("LOL Idiotenklupp");
List<String> gast = new ArrayList<String>();
gast.add("KG Wallau");
gast.add("DJ G4bby");
gast.add("Hanzup Motherf*ckers");
adapter = new SpieleAdapterFuerCustomList(getActivity(), dateAndSchiri, heim, gast);
setListAdapter(adapter);
return view;
}
public void FormatiereSpieleSeite(String mannschaft)
{
// aktive
if(mannschaft.equals("Herren 1"))
ligaId = "X0";
if(mannschaft.equals("Herren 2"))
ligaId = "00151350asd0";
if(mannschaft.equals("Herren 3"))
ligaId = "00151asdad000000000000000001000";
if(mannschaft.equals("Damen 1"))
ligaId = "001513asdad0000000007000";
if(mannschaft.equals("Damen 2"))
ligaId = "0015135asd0000000000003000";
// jugend
if(mannschaft.equals("männl. A"))
ligaId = "0015135asdasd0000000000001000";
if(mannschaft.equals("weibl. A"))
ligaId = "";
if(mannschaft.equals("männl. B1"))
ligaId = "001513asdasd0000000000000002000";
if(mannschaft.equals("männl. B2"))
ligaId = "00151350asd05502000000000000001000";
if(mannschaft.equals("männl. C"))
ligaId = "0015asdasd503000000000000001000";
if(mannschaft.equals("männl. D"))
ligaId = "001513504501asdsad0000001000";
if(mannschaft.equals("E-Jugend"))
ligaId = "0015135asdasd000000000003000";
System.out.println(ligaId + "Das ist liga");
List<String> dateAndSchiri = new ArrayList<String>();
dateAndSchiri.add("DATUM as Schiri 2");
dateAndSchiri.add("DATUMasas Schisdfsdfri 2");
dateAndSchiri.add("DATUMasas Schirsdfsfi 2");
List<String> heim = new ArrayList<String>();
heim.add("HSG Nieder-sdfRoden");
heim.add("SG Brucsdfhköbel");
heim.add("LOL Idiosdfsdftenklupp");
List<String> gast = new ArrayList<String>();
gast.add("KG Walsdfsflau");
gast.add("DJ G4sdfsfbby");
gast.add("Hanzusdfsfp Motherf*ckers");
adapter = new SpieleAdapterFuerCustomList(getActivity(), dateAndSchiri, heim, gast);
adapter.notifyDataSetChanged();
setListAdapter(adapter);
}
}
一切都好,运行正常。
在“主”级上。包含viewpager和tabsactionbar的类具有菜单。如果用户单击其中一个,则必须加载新的ListFragment。或者新的BaseAdapter(?)。 我希望ListFragment(类:Spiele)是updatet。 但我怎么能这样做? 如何更新我的ListFragment?
答案 0 :(得分:0)
为什么这个ArrayList有TabInfo?为什么不直接使用带有Fragments的ArrayList。而不是在适配器中,而是在Activity本身?
在这种情况下,您可以执行以下操作:
1
public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args)
{
tab.setTabListener(this);
Fragment f = Fragment.instantiate(mContext, clss.getName(), args);
mFragments.add(f);
mActionBar.addTab(tab);
notifyDataSetChanged();
}
2
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
if(!item.getTitle().toString().equals("Active") || !item.getTitle().toString().equals("Jugend"))
{
Fragment f = mFragments.get(getSupportActionBar().getSelectedTab().getPosition());
((Spiele)f).FormatiereSpieleSeite(item.getTitle().toString());
}
return true;
}
如果我理解正确你想要做的就是更换适配器。正确?

解决方案比我想象的更容易。
这些https://stackoverflow.com/a/7393477/1231245帮助我从ViewPager的第一个片段中找到了FragmentTag。
我可以轻松地在onOptionsItemSelected方法中创建和设置适配器。 这是它:
List<String> dateAndSchiri = new ArrayList<String>();
dateAndSchiri.add.....
List<String> heim = new ArrayList<String>();
heim.add.....
List<String> gast = new ArrayList<String>();
gast.add.....
SpieleAdapterFuerCustomList adapter = new SpieleAdapterFuerCustomList(getBaseContext(), dateAndSchiri, heim, gast);
Spiele articleFrag = (Spiele) getSupportFragmentManager().findFragmentByTag("android:switcher:"+R.id.pager+":0");
articleFrag.setListAdapter(adapter);
您可以使用不同的ArrayList创建一个新的适配器,并使用不同的单击菜单...
