You can't use ViewPager to swipe between Activities. You need to convert each of you five Activities into Fragments, then combine everything in one FragmentActivity with the Adapter you use with ViewPager.

这里有一个链接的进入细节将你当前的活动信息片段

Here's a link that goes into detail on converting your current Activities info Fragments.

这是Android开发者网站上的片段话题，它有很多有用的信息。

This is the Fragment topic on the Android Developers website, it has a lot of useful info.

这里的另一个例子（完整的源代码），其膨胀 TextViews 每一页上。

Here's another example (full source) that inflates TextViews on each page.

下面是我打了一个例子：

Here's an example that I typed up:

PagerAdapter

public class PagerAdapter extends FragmentPagerAdapter {

    private final List<Fragment> mFragments = new ArrayList<Fragment>();

    public PagerAdapter(FragmentManager manager) {
        super(manager);
    }

    public void addFragment(Fragment fragment) {
        mFragments.add(fragment);
        notifyDataSetChanged();
    }

    @Override
    public int getCount() {
        return mFragments.size();
    }

    @Override
    public Fragment getItem(int position) {
        return mFragments.get(position);
    }
}

这应该叫的onCreate 你的 FragmentActivity

This should be called in onCreate of your FragmentActivity:

    private void initPaging() {

    FragmentOne fragmentOne = new FragmentOne();
    FragmentTwo fragmentTwo= new FragmentTwo();

    PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager());
    pagerAdapter.addFragment(fragmentOne);
    pagerAdapter.addFragment(fragmentTwo);

    ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
    viewPager.setAdapter(pagerAdapter);
}

这是你使用的布局的一个例子你的 FragmnetActivity

This is an example of the layout you'd use for your FragmnetActivity:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

<android.support.v4.view.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</LinearLayout>

要创建片段创建扩展片段一个新的类。你会想前两种方法覆盖是 onActivityCreated 和 onCreateView 。

To create Fragment create a new class that extends Fragment. The first two methods you'll want to override are onActivityCreated and onCreateView.

这里是你如何能做到这一点：

public class FragmentOne extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(THE_LAYOUT_FROM_YOUR_ORIGINAL_ACTIVITY, container, false);
    return view;
    }
}
