我已经创建了使用ViewPagerExtensions swipey标签，但这次我只用一个库ActionBarSherlock在我的应用程序，我不知道如何创建swipey标签像谷歌Play商店。如果你能帮助我完成它，我会很感激你。

I have created swipey tabs using ViewPagerExtensions but this time i am using only one library ActionBarSherlock in my App and i dont know how to create swipey tabs like google play store. If you can help me to get it done, i'd be very thankful to you.

这是我的活动类的onCreate方法

This is the onCreate method of my activity class

 @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"));
        }
    }

在顶部全新付费第一形象是当前屏幕的标题和另外两个都出现了previous或下一屏幕​​瓷砖。我该怎么让previous和下一屏幕标题角落喜欢它的一些淡入效果。

In first image Top New Paid is the current screen title and other two are showing previous or next screen tile. How can i show previous and next screen title at corner with some fading effect like it.

推荐答案

您需要使用动作条的标签，一个TabsAdapter和ViewPager（scrolly位）。这里有一个完整的教程中，我做： http://davidjkelley.net/?p=34 （只需使用进口ABS，不标准兼容库的）。

You need to use ActionBar Tabs, a TabsAdapter and a ViewPager (scrolly bit). Here's a full tutorial I made: http://davidjkelley.net/?p=34 (just use the ABS imports, not standard compatibility library ones).

下面是一些相关的code：
