雖然我意識到,嵌套的片段是不是一種選擇,我仍然有我簡直想不出回答的問題。如何更換從一個TabAdapter一個選項卡中的片段?
我使用ActionBarSherlock的FragmentsTabPager例如創建一個界面,就可以通過網頁的標籤與刷卡,而不是點擊選項卡。我的問題是這些選項卡中的一個包含listview。點擊該列表視圖,包含一個新的列表(基於項目數據點擊)不同的片段推出。我如何做到這一點?
我想你可能需要一個位COSE從我BaseActivity(那個以ViewPager和TabsAdapter
*snippet*
public class BaseActivity extends SherlockFragmentActivity {
TabHost mTabHost;
ViewPager mViewPager;
TabsAdapter mTabsAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_tabs_pager);
mTabHost = (TabHost)findViewById(android.R.id.tabhost);
mTabHost.setup();
mViewPager = (ViewPager)findViewById(R.id.pager);
mTabsAdapter = new TabsAdapter(this, mTabHost, mViewPager);
mTabsAdapter.addTab(mTabHost.newTabSpec("home").setIndicator("Home"),
FragmentStackSupport.CountingFragment.class, null);
mTabsAdapter.addTab(mTabHost.newTabSpec("players").setIndicator("PLAYERS"),
PlayerRankingFragment.class, null);
mTabsAdapter.addTab(mTabHost.newTabSpec("teams").setIndicator("TEAMS"),
FederationRanksFragment.class, null);
if (savedInstanceState != null) {
mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab"));
}
}
/**
* This is a helper class that implements the management of tabs and all
* details of connecting a ViewPager with associated TabHost. It relies on a
* trick. Normally a tab host has a simple API for supplying a View or
* Intent that each tab will show. This is not sufficient for switching
* between pages. So instead we make the content part of the tab host
* 0dp high (it is not shown) and the TabsAdapter supplies its own dummy
* view to show as the tab content. It listens to changes in tabs, and takes
* care of switch to the correct paged in the ViewPager whenever the selected
* tab changes.

public static class TabsAdapter extends FragmentPagerAdapter
implements TabHost.OnTabChangeListener, ViewPager.OnPageChangeListener {
private final Context mContext;
private final TabHost mTabHost;
private final ViewPager mViewPager;
private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>();
static final class TabInfo {
private final String tag;
private final Class<?> clss;
private final Bundle args;
TabInfo(String _tag, Class<?> _class, Bundle _args) {
tag = _tag;
clss = _class;
args = _args;
}
}

BaseActivity - >選項卡 「團隊」 - >團隊的ListView(AllianceFragment) - >團隊。項目已點擊 - >玩家的ListView(PlayersFragment)

你能告訴我們你的PlayerRankingFragment.class和xml佈局嗎? – Jeroen
