我已经使用ViewPagerExtensions创建了swipey标签,但这次我在我的应用程序中只使用一个库ActionBarSherlock,我不知道如何创建谷歌游戏商店的swipey选项卡.如果你能帮我完成,我会非常感谢你.
这是我活动类的onCreate方法
@Override
protected void onCreate(Bundle savedInstanceState) {
setTheme(SampleList.THEME); //Used for theme switching in samples
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_tabs);
mTabHost = (TabHost)findViewById(android.R.id.tabhost);
mTabHost.setup();
mTabManager = new TabManager(this,mTabHost,R.id.realtabcontent);
mTabManager.addTab(mTabHost.newTabSpec("simple").setIndicator("Groups"),FragmentStackSupport.CountingFragment.class,null);
mTabManager.addTab(mTabHost.newTabSpec("contacts").setIndicator("Contacts"),LoaderCursorSupport.CursorLoaderListFragment.class,null);
mTabManager.addTab(mTabHost.newTabSpec("custom").setIndicator("Logs"),LoaderCustomSupport.AppListFragment.class,null);
mTabManager.addTab(mTabHost.newTabSpec("throttle").setIndicator("Gallery"),LoaderThrottleSupport.ThrottledLoaderListFragment.class,null);
if (savedInstanceState != null) {
mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab"));
}
}
在第一个图像顶部新付费是当前的屏幕标题,其他两个显示上一个或下一个屏幕瓦片.如何显示上一个和下一个屏幕标题在角落有一些像这样的衰落效果.
解决方法
您需要使用ActionBar Tabs,TabsAdapter和ViewPager(scrolly位).这里有一个完整的教程：

以下是一些相关代码：
import java.util.ArrayList;
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.MenuItem.OnMenuItemClickListener;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
public class Polling extends FragmentActivity {
private ViewPager mViewPager;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mViewPager = new ViewPager(this);
mViewPager.setId(R.id.pager);
setContentView(mViewPager);
final ActionBar bar = getActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayShowTitleEnabled(false);
bar.setDisplayShowHomeEnabled(false);
mTabsAdapter = new TabsAdapter(this,mViewPager);
mTabsAdapter.addTab(bar.newTab().setText(R.string.login),LoginFragment.class,null);
mTabsAdapter.addTab(bar.newTab().setText(R.string.economics),EconFragment.class,null);

tab.setTag(info);
tab.setTabListener(this);
mTabs.add(info);
mActionBar.addTab(tab);
notifyDataSetChanged();
}
public int getCount() {
return mTabs.size();
}
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 onPageScrollStateChanged(int state) {

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,android.app.FragmentTransaction ft) {}
@Override
public void onTabSelected(Tab tab,android.app.FragmentTransaction ft) {

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