ScrollView doesn't work in fragment

问题

Does anyone know why the scroll does not work ? I trying to make my page scrollable and can swipe to another tab. It allows me to swipe but not scrollable. I'm use most of the answer in Stack Overflow but none of them is worked in my case.

You have to add child views to linearLayout.

try something like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
android:orientation="vertical"
tools:context="com.example.samplestackoademo.MainActivity" >

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:background="#FFFFFF"
    android:fillViewport="true"
    android:orientation="vertical" >

    <AbsoluteLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

Add fragment to View Pager.

add adapter to view pager in your onCreate() method of activity.

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

    // Intializing view from xml file
    ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
    // adding adapter to view pager
    VideoViewPagerAdapter adapter = new VideoViewPagerAdapter(
            getSupportFragmentManager());
    viewPager.setAdapter(adapter);
    viewPager.setCurrentItem(0, true);
}

FragmentPagerAdapter.java

public class VideoViewPagerAdapter extends FragmentPagerAdapter {

private String[] urls = { "HelloText--", "HellooText--", "HelloText--",
        "HellooText--" };

public VideoViewPagerAdapter(FragmentManager fragmentManager) {
    super(fragmentManager);
}

@Override
public int getCount() {
    return urls.length;
}

@Override
public Fragment getItem(int position) {
    // Create fragment object
    VideoPlayerFragment fragment = new VideoPlayerFragment();

    Bundle args = new Bundle();
    args.putString("STRING_URL", urls[position] + "" + position);

    fragment.setArguments(args);

    return fragment;
}

@Override
public CharSequence getPageTitle(int position) {
    return "Page " + (position + 1);
}
}

viewpager_layout.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:gravity="center"
    android:padding="10dp"
    android:text="Helloooo"
    android:textSize="18dp" />

 </LinearLayout>

MyFragment.java

public class VideoPlayerFragment extends Fragment {

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.viewpager_layout, container, false);
    TextView textView = (TextView) v.findViewById(R.id.pager_textView);
    String data = getArguments().getString("STRING_URL");
    textView.setText(data);
    return v;
}
