为何我的viewpager无法在片段中工作？

我的片段有以下代码.我几乎从一个基本的视图分页器示例中获取了此信息,并将其打包为一个片段,以测试我正在处理的项目.

我正在使用ACtionBarSherlock和viewPagerIndicator库.下面的片段包含一个viewPager,在本示例中,该viewPager应该在简单的标题字符串之间滑动.

我在一个活动中使用ViewPager和ViewPagerIndicator尝试了该示例,没有问题.但是第二个我把它弄成碎片. BOOM,只有黑屏…没有错误,只有黑屏…我感觉我一定是在膨胀,或者错误地访问了布局…
有任何想法吗？

这是代码：

public class TestFragment extends SherlockFragment {

    //~Constants----------------------------------------------


    //~Data Fields--------------------------------------------

    //~Constructors--------------------------------------------
    @Override
    public void onCreate(Bundle savedInstanceState) {

        //Setup view
        super.onCreate(savedInstanceState);
        View view = onCreateView(getLayoutInflater(savedInstanceState), null, savedInstanceState);

        ViewPagerAdapter adapter = new ViewPagerAdapter( this.getSherlockActivity() );
        ViewPager pager = 
            (ViewPager)view.findViewById(R.id.free_time_day_pager);
        TitlePageIndicator indicator = 
            (TitlePageIndicator)view.findViewById(R.id.titles);
        pager.setAdapter( adapter );
        indicator.setViewPager( pager );
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.free_time_fragment_layout, null, false);
        return view;
    }

    //~Methods-------------------------------------------------
}

解决方法:

不要调用错误的onCreateView.

onCreateView是一个重写的方法,由FragmentManger调用以处理Fragment的生命周期.

private ViewPager mViewPager;
private TitlePagerIndicator mIndicator;

// Called first
@Override
public void onCreate(Bundle savedInstanceState) {
    //Setup view
    super.onCreate(savedInstanceState);
}

// Called second
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.free_time_fragment_layout, null, false);
    return view;
}

// Called third
@Override
public View onViewCreated(View v){
    super.onViewCreated(v);
    mViewPager = (ViewPager) v.findViewById(R.id.free_time_day_pager);
    mIndicator = (TitlePageIndicator)v.findViewById(R.id.titles);

}


public void onActivityCreated(Bundle bdl){
    super.onActivityCreated(bdl);
    ViewPagerAdapter adapter = new ViewPagerAdapter( getSherlockActivity() );
    mViewPager.setAdapter(adapter);
    mIndicator.setViewPager(pager);
}

还请注意,如果您使用的是FragmentPagerAdapter,则需要一种特殊的方法来创建ViewPagerFragment,这有点棘手,但请参阅此gist.

也了解有关片段生命周期here的信息.

干杯
