怎么在fragment里添加viewpager

fragment1 Class One对应的布局文件 one.xml

<android.support.v4.view.ViewPager

android:id="@+id/one_vp"

android:layout_width="match_parent"

android:layout_height="match_parent"/>

fragment1对应的类Class One:

public class One extends Fragment {

private List<Fragment>list = new ArrayList<Fragment>()

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.one, null)

return view

}

@Override

public void onActivityCreated(Bundle savedInstanceState) {

super.onActivityCreated(savedInstanceState)

ViewPager vp = (ViewPager) getView().findViewById(R.id.one_vp)

list.add(new FragOne())//子fragment

list.add(new FragTwo())//子fragment

VpAdapter adapter = new VpAdapter(getChildFragmentManager(), list)

vp.setAdapter(adapter)

}

}

漏掉VpAdapter类了：

public class VpAdapter extends FragmentPagerAdapter {

private List<Fragment>list = new ArrayList<Fragment>()

public VpAdapter(FragmentManager fm) {

super(fm)

}

public VpAdapter(FragmentManager fm, List<Fragment>list) {

super(fm)

this.list = list

}

@Override

public Fragment getItem(int i) {

return list.get(i)

}

@Override

public int getCount() {

return list.size()

}

}
