Question

我制作了一个导航抽屉，因为您知道导航抽屉将有一个容器，其中所有布局都是膨胀的。我需要在其中一个页面上有一个可滚动的标签。我有问题将viewPager布局膨胀到容器中，该容器在以下片段类中实现：

public class Pager extends Fragment {

ViewPager viewPager = null;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getActivity().setContentView(R.layout.fragment_pager);
    viewPager = (ViewPager) getActivity().findViewById(R.id.pager);

    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    MyAdapter myAdapter = new MyAdapter(fragmentManager);
    viewPager.setAdapter(myAdapter);
}
}


class MyAdapter extends FragmentPagerAdapter{

Fragment fragment = null;

public MyAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int position) {

    switch (position){
        case 0:
            fragment = new MapFragment();
            break;
        case 1:
            fragment = new RegisterRestaurants();
            break;
    }
    return fragment;
}

@Override
public int getCount() {

    return 2;
}

}

layout fragment_pager：

<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android">
</android.support.v4.view.ViewPager>

希望有人可以提供帮助，我浏览互联网，所有教程都是在FragmentActivity中进行的，但在我的情况下，我必须在片段中进行操作

<!-- android:layout_gravity="start" tells DrawerLayout to treat
     this as a sliding drawer on the left side for left-to-right
     languages and on the right side for right-to-left languages.
     If you're not building against API 17 or higher, use
     android:layout_gravity="left" instead. -->

</android.support.v4.widget.DrawerLayout>'

你可以做下一个：

public class Pager extends Fragment {

    ViewPager viewPager = null;

    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_pager, container, false);
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        viewPager = (ViewPager) view.findViewById(R.id.container);

        MyAdapter myAdapter = new MyAdapter();
        viewPager.setAdapter(myAdapter);
    }

    class MyAdapter extends FragmentPagerAdapter {

        Fragment fragment = null;

        public MyAdapter() {
            super(getChildFragmentManager());
        }

        @Override
        public Fragment getItem(int position) {

            switch (position) {
                case 0:
                    fragment = new MapFragment();
                break;
                case 1:
                    fragment = new RegisterRestaurants();
                    break;
            }
            return fragment;
        }

        @Override
        public int getCount() {

            return 2;
        }
    }
}

public class PagerActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_pager);

        if (savedInstanceState == null) {
            getSupportFragmentManager()
                    .beginTransaction()
                    .add(R.id.holder, new Pager())
                    .commit();
        }
    }
}

fragment_pager.xml：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
                                   android:id="@+id/pager"
                                   android:layout_width="match_parent"
                                   android:layout_height="wrap_content">
</android.support.v4.view.ViewPager>

activity_pager.xml：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout  xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/holder"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

</FrameLayout>

修改

activity_pager.xml可以有下一个：

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


<FrameLayout
        android:id="@+id/holder"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
</FrameLayout>

<fragment android:id="@+id/navigation_drawer"
          android:tag="navtag"
          android:layout_width="240dp"
          android:layout_height="match_parent"
          android:layout_gravity="left"
          android:name="com.example.NavigationFragment" />

</android.support.v4.widget.DrawerLayout>

用viewPager替换容器
