Question

我有一个CollapsingToolbarLayout及以下，我有一个LinearLayout，其中包含fragments和ViewPager。但是，当我滚动时，fragments都保持粘性，只有包含viewpager的{{1}}正在滚动。如何同时制作RecyclerView fragments？

activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/mainactivity"
    android:orientation="vertical">

    <android.support.v4.view.ViewPager
        android:id="@+id/viewPager"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

</LinearLayout>

MainActivity

public class MainActivity extends AppCompatActivity {

    MyPagerAdapter TabAdapter;

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

        final ViewPager pager = (ViewPager) findViewById(R.id.viewPager);
        pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
        pager.setOffscreenPageLimit(2);

    private class MyPagerAdapter extends FragmentStatePagerAdapter {

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

        @Override
        public Fragment getItem(int pos) {
            switch (pos) {

                case 0:
                    return SHGCreationFragmentFirst.newInstance("SHGCreationFragmentFirst, Instance 1");
                case 1:
                    return MemberListFragment.newInstance("MemberListFragment, Instance 2");
            }
            return null;
        }

        @Override
        public int getItemPosition(Object object) {
            return POSITION_NONE;
        }


        @Override
        public int getCount() {
            return 2;
        }

    }
}

FragmentFirst

public class FragmentFirst extends Fragment {



       @Override
       public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
           View v = inflater.inflate(R.layout.fragment_first, container, false);

       return v;
   }

    public static FragmentFirst newInstance(String text) {

        FragmentFirst f = new FragmentFirst();
        Bundle b = new Bundle();
        b.putString("msg", text);

        f.setArguments(b);

        return f;
    }


}

FragmentSecond

public class FragmentSecond extends Fragment {



           @Override
           public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
               View v = inflater.inflate(R.layout.fragment_second, container, false);

           return v;
       }

        public static FragmentSecond newInstance(String text) {

            FragmentSecond f = new FragmentSecond();
            Bundle b = new Bundle();
            b.putString("msg", text);

            f.setArguments(b);

            return f;
        }


    }

fragment_first.xml

    <?xml version="1.0" encoding="utf-8"?>


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#000000"
            android:orientation="vertical"
            android:padding="10dp">


        </LinearLayout>

fragment_Second.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#fcfcfc"
            android:orientation="vertical"
            android:padding="10dp">


        </LinearLayout>
