我的应用程序使用了 android.support.v4.view.ViewPager 类。在ViewPager每一页，我想在那里为一个片段，每个都有自己的布局文件。每个片段在其自己的文件中定义。我有一个很难实现这一点。为了澄清，有：

My app uses the android.support.v4.view.ViewPager class. For each page in the ViewPager, I want there to be one Fragment, each with its own layout file. Each Fragment is defined in its own file. I am having a hard time implementing this. To clarify, there is:

1 ViewPager 4片段文件 - FragmentOne.class，FragmentTwo.class，FragmentThree.class，FragmentFour.class 4 XML布局文件 - frag_one.xml，frag_two.xml，frag_three.xml，frag_four.xml

1 ViewPager 4 Fragment Files - FragmentOne.class, FragmentTwo.class, FragmentThree.class, FragmentFour.class 4 XML Layout Files - frag_one.xml, frag_two.xml, frag_three.xml, frag_four.xml

这是我只看到这些例子涉及一个布局文件。

The examples that I have seen only deal with one layout file.

下面是我FragmentActivity其中ViewPager举行：

Here is my FragmentActivity where the ViewPager is held:

public class Main extends FragmentActivity {
    MyAdapter mAdapter;
    ViewPager mPager;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mAdapter = new MyAdapter(getSupportFragmentManager());

        mPager = (ViewPager) findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);

    }

    public static class MyAdapter extends FragmentPagerAdapter {
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public int getCount() {
            return 4;
        }

        @Override
        public Fragment getItem(int position) {
            return EditorFragment.newInstance(position);
        }
    }

}

我的主要问题是：我如何获取适配器， MyAdapter ，跨承认他们的四个独立的片段文件，顺利页面ViewPager？我应该做出什么样的修改的getItem（）？

My main question is: How do I get the adapter, MyAdapter, to recognize the four separate Fragment files and smoothly page across them with ViewPager? What kind of modifications should I make to getItem()?

任何帮助是AP preciated。

Any help is appreciated.

编辑：

所以，我试了一下lulumeya建议，并提出了这一点：

So, I tried what lulumeya suggested and came up with this:

编辑2：是的，那些break语句固定它。它的工作原理吧。感谢大家谁帮助！现在我有一个很好的隔离，谢谢。

EDIT 2: Yes, those break statements fixed it. It works now. Thanks to everyone who helped! Now I have a nice segregation, thanks.

    @Override
    public Fragment getItem(int position) {
        Fragment f = new Fragment();

        switch (position) {
        case 0:
            f = FragmentOne.newInstance(position);
                    break;
        case 1:
            f = FragmentTwo.newInstance(position);
                    break;
        case 2:
            f = FragmentThree.newInstance(position);
                    break;
        case 3:
            f = FragmentFour.newInstance(position);
                    break;
        }

        return f;
    }

该应用程序lauches，这始终是一个好兆头，但卡在布局四人。当我页，这也是布局四，对所有页面的权利。我一定要改变布局充气的每个片段。我仍然会在这方面努力。 @lulumeya - 这是你的意思

The app lauches, which is always a good sign, but is stuck on layout four. When I page to the right it is also layout four, for all pages. I was sure to change the layout in the inflater for each Fragment. I am still going to work on this. @lulumeya - Is this what you meant?

推荐答案

刚刚在的getItem（INT位置）位置返回正确的片段实例。 用开关〜情况下，这很容易。

Just return proper Fragment instance in getItem(int position) by position. use switch~case, It's easy.
