禁用RecyclerView滚动，让scrollview CHILD可以滚动

Question

RecyclerView 内的ScrollView

子元素由适配器插入，回收器被分割，第三个子元素是滚动视图，但它必须在放置第一个和第二个子元素后的剩余空间中滚动。

我需要在不禁用scrollview的情况下禁用recyclerview滚动

回收容器

<RelativeLayout
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="@color/Lightgrey"
tools:context="com.inhousecrew.nocturnalkey.fragments.NightDetailsFragment">

            <android.support.v7.widget.RecyclerView
            android:id="@+id/nightlife_detailsrecycler"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:overScrollMode="never"
            android:background="@color/Background"
            />


</RelativeLayout>

这些是滚动视图容器（recyclerview 的第三个孩子）的 XML 初始属性

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="220dp"
android:layout_gravity="bottom"
android:id="@+id/scroll_details"
android:background="@color/Lightgrey">

<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="false">

</ScrollView>
</FrameLayout>

最后这是包含回收器的 java 类，出于逻辑目的，我使用适配器来更改第一个孩子中的数据，这就是我使用 recyclerview 的原因（首先）

public class NightDetailsFragment extends Fragment {


private RecyclerView mRecyclerNight;
private NightDetailsAdapter mAdapter;

private OnFragmentInteractionListener mListener;



public static NightlifeFragment newInstance() {
    NightlifeFragment fragment = new NightlifeFragment();
    Bundle args = new Bundle();
    fragment.setArguments(args);

    return fragment;
}

public NightDetailsFragment() {

}

public List<Information> getData() {
    //load only static data inside a drawer
    List<com.inhousecrew.nocturnalkey.fragments.Information> data = new ArrayList<>();
    int icons = R.drawable.settings_w;
    String titles = "Settings";
    int background = R.drawable.background_user;


        com.inhousecrew.nocturnalkey.fragments.Information information = new com.inhousecrew.nocturnalkey.fragments.Information();
        information.title = titles;
        information.iconId = icons;
        information.backgroundId = background;
        if(titles.equals("Profile")){
            information.nightlife_active = getResources().getColor(R.color.inactive_event);
        }else{
            information.nightlife_active = getResources().getColor(R.color.Yellow);
        }

        data.add(information);


    return data;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_night_details, container, false);
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    mRecyclerNight = (RecyclerView) view.findViewById(R.id.nightlife_detailsrecycler);
    mAdapter = new NightDetailsAdapter(getActivity() ,getData());

    mRecyclerNight.setAdapter(mAdapter);
    mRecyclerNight.setLayoutManager(new LinearLayoutManager(getActivity()));

}



public void onButtonPressed(Uri uri) {
    if (mListener != null) {
        mListener.onFragmentInteraction(uri);
    }
}

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    try {
        mListener = (OnFragmentInteractionListener) activity;
    } catch (ClassCastException e) {
        throw new ClassCastException(activity.toString()
                + " must implement OnFragmentInteractionListener");
    }
}

@Override
public void onDetach() {
    super.onDetach();
    mListener = null;
}

public interface OnFragmentInteractionListener {

    public void onFragmentInteraction(Uri uri);
}

}

您可以像这样子类化 RecyclerView 并覆盖 onMeasure：

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, heightSpec);
    getLayoutParams().height = getMeasuredHeight();
}
