问题描述

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。

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).
