Question

有关如何在ViewPager上的每个页面上设置单独活动的任何想法。我使用FragmentActivity尝试兼容包，但是在给定的示例中，它只是一个类型是ListFragment。

我从兼容性v4的样本中复制的代码：

public class ViewPagerListActivity extends FragmentActivity {
static final int NUM_ITEMS = 10;

MyAdapter mAdapter;

ViewPager mPager;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_pager);

    mAdapter = new MyAdapter(getSupportFragmentManager());

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

    // Watch for button clicks.
    Button button = (Button)findViewById(R.id.goto_first);
    button.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            mPager.setCurrentItem(0);
        }
    });
    button = (Button)findViewById(R.id.goto_last);
    button.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            mPager.setCurrentItem(NUM_ITEMS-1);
        }
    });
}

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

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

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

public static class ArrayListFragment extends ListFragment {
    int mNum;

    /**
     * Create a new instance of CountingFragment, providing "num"
     * as an argument.
     */
    static ArrayListFragment newInstance(int num) {
        ArrayListFragment f = new ArrayListFragment();

        // Supply num input as an argument.
        Bundle args = new Bundle();
        args.putInt("num", num);
        f.setArguments(args);

        return f;
    }

    /**
     * When creating, retrieve this instance's number from its arguments.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mNum = getArguments() != null ? getArguments().getInt("num") : 1;
    }

    /**
     * The Fragment's UI is just a simple text view showing its
     * instance number.
     */
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_pager_list, container, false);
        View tv = v.findViewById(R.id.text);
        ((TextView)tv).setText("Fragment #" + mNum);
        return v;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        setListAdapter(new ArrayAdapter<String>(getActivity(),
                android.R.layout.simple_list_item_1, Cheeses.sCheeseStrings));
    }

    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
        Log.i("FragmentList", "Item clicked: " + id);
    }
}

}

以下执行：

ViewPagerListActivity

我想在每个ViewPager上放置具有特定UI和进程的活动或视图，而不仅仅是上面代码示例中的一个类型ListView。例如，第1页是地图信息;第2页是TextView，EditView和按钮的组合，第3页是Gallery;等等。有没有想过实现它？或者有任何教程吗？

ViewPager包含每个页面的单独活动
