Question

我有viewPager使用FragmentStatePagerAdapter作为适配器，在片段类中使用getItem()适配器函数我在运行时使用片段管理器添加一些其他片段。正确显示了页面零（起始页）的碎片，但是对于任何其他页面我应该滑过它然后再刷回它以查看内容。（因为我检查每次滑动导致内部碎片和碎片管理器表现正确，即使是第一次但是最初没有显示任何内容）任何解决方案都很受欢提前致谢

主类中的适配器代码

class FragmntProducer extends FragmentStatePagerAdapter{

    public FragmntProducer(FragmentManager fm) {
        super(fm);
        // TODO Auto-generated constructor stub
    }

    @Override
    public Fragment getItem(int arg0) {
        // TODO Auto-generated method stub
        return new PagerFragment(pager.getCurrentItem());
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return Integer.MAX_VALUE;
    }

}

用于viewpager的片段类

public class PagerFragment extends Fragment {

WeekView rowOne , rowTwo , rowThree , rowFour , rowFive , rowSix;
int cis;

public PagerFragment(int ci) {
    // TODO Auto-generated constructor stub
    cis = ci;
//      Toast.makeText(getContext(), ci+"under construct", Toast.LENGTH_SHORT).show();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View layout = inflater.inflate(R.layout.pager_fragment_layout, container, false);
    Toast.makeText(getContext(),"page: "+cis,Toast.LENGTH_SHORT).show();
//      rowOne = new WeekView();
//      getFragmentManager().beginTransaction().add(R.id.week_one, rowOne).commit();
    rowTwo = new WeekView();
    getFragmentManager().beginTransaction().add(R.id.week_two, rowTwo).commit();
//      rowThree = new WeekView();
//      getFragmentManager().beginTransaction().add(R.id.week_three, rowThree).commit();
    rowFour = new WeekView();
    getFragmentManager().beginTransaction().add(R.id.week_four, rowFour).commit();
    rowFive = new WeekView();
    getFragmentManager().beginTransaction().add(R.id.week_five, rowFive).commit();
    rowSix = new WeekView();
    getFragmentManager().beginTransaction().add(R.id.week_six, rowSix).commit();
    super.onCreateView(inflater, container, savedInstanceState);
    return layout;
}

}

viewPager片段的xml布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<fragment
    android:id="@+id/week_one"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:name="com.cal.calendar.WeekView"/>

<FrameLayout 
    android:id="@+id/week_two"
    android:layout_width="match_parent"
    android:layout_height="40dp"/>

<fragment
    android:id="@+id/week_three"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:name="com.cal.calendar.WeekView"/>

<FrameLayout
    android:id="@+id/week_four"
    android:layout_width="match_parent"
    android:layout_height="40dp"/>

<FrameLayout
    android:id="@+id/week_five"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    android:name="com.cal.calendar.WeekView"/>

<FrameLayout
    android:id="@+id/week_six"
    android:layout_width="match_parent"
    android:layout_height="40dp"/>
