【问题描述】：

我正在使用自定义适配器类来处理 RecyclerView，这是我的代码：

public class CardAdapter extends RecyclerView.Adapter<CardAdapter.ViewHolder> {

    List<NatureItem> mItems;

    public CardAdapter() {
        super();
        mItems = new ArrayList<NatureItem>();

        NatureItem nature = new NatureItem();

        nature.setName("The Great Barrier Reef");
        nature.setThumbnail(R.drawable.great_barrier_reef);
        mItems.add(nature);

        nature = new NatureItem();
        nature.setName("Grand Canyon");
        nature.setThumbnail(R.drawable.grand_canyon);
        mItems.add(nature);

    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext())
                .inflate(R.layout.recycler_view_card_item, viewGroup, false);
        ViewHolder viewHolder = new ViewHolder(v);
        return viewHolder;
    }

    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int i) {
        NatureItem nature = mItems.get(i);
        viewHolder.tvNature.setText(nature.getName());
        viewHolder.imgThumbnail.setImageResource(nature.getThumbnail());
    }

    @Override
    public int getItemCount() {
        return mItems.size();
    }

    class ViewHolder extends RecyclerView.ViewHolder{

        public ImageView imgThumbnail;
        public TextView tvNature;

        public ViewHolder(View itemView) {
            super(itemView);
            imgThumbnail = (ImageView)itemView.findViewById(R.id.img_thumbnail);
            tvNature = (TextView)itemView.findViewById(R.id.tv_nature);
        }
    }
}

这是完整的日志：

CartAdapter 行号：53

    View v = LayoutInflater.from(viewGroup.getContext())

CartAdapter 行号：18

   public class CardAdapter extends RecyclerView.Adapter<CardAdapter.ViewHolder> {

可能是什么原因？为什么我会遇到这个问题。我还有什么需要改变的地方吗？

解决方案由@Abhishek 和@Shvet 提供，它解决了异常但仍然得到类似的东西，默认情况下RecyclerView over MaterialViewPager（这不好）

再次编辑：

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

        mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
        mRecyclerView.setHasFixedSize(true);

        mLayoutManager = new GridLayoutManager(getActivity(), 2);
        mRecyclerView.setLayoutManager(mLayoutManager);

        // mAdapter = new CardAdapter();
        mAdapter = new RecyclerViewMaterialAdapter(new CardAdapter());
        mRecyclerView.setAdapter(mAdapter);

        MaterialViewPagerHelper.registerRecyclerView(getActivity(), mRecyclerView, null);

        mRecyclerView.addOnItemTouchListener(
                new RecyclerItemClickListener(getActivity(), new RecyclerItemClickListener.OnItemClickListener() {
                    @Override
                    public void onItemClick(View view, int position) {

                        Toast.makeText(getActivity(), String.valueOf(position), Toast.LENGTH_LONG).show();

                    }
                })
        );

    }
}

【问题讨论】：

您的 XML 文件是什么样的？
@BidhanA 我也发布了 xml
你的 build.gradle 文件中是否包含所有依赖项？
是的..我是所有的依赖项
请试试这个.... 将 public class CardAdapter extends RecyclerView.Adapter { 替换为 public class CardAdapter extends RecyclerView.Adapter {

标签： android xml android-fragments view adapter

【解决方案1】：

我在示例应用程序中尝试了您的代码。我花了一段时间才弄清楚recycler_view_card_item.xml 下面的两行是导致问题的原因。

android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"

如果我是正确的（我不能确定，因为你没有发布那部分代码），你没有在默认的dimens.xml 中声明activity_horizontal_margin (res\values\dimens. xml)。您需要在默认尺寸中声明它以解决问题，类似于这样

dimens.xml

<resources>
    <dimen name="activity_horizontal_margin">64dp</dimen>
</resources>

希望对您有所帮助:)

编辑： 您需要在片段中添加占位符才能下推 Recycler 视图。请参阅 MaterialViewPager 库的使用指南 - https://github.com/florent37/MaterialViewPager。那里已经提到了这一点。

将您的 fragment_recyclerview_advance.xml 更改为

<?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="wrap_content"
    android:orientation="vertical">

    <include layout="@layout/material_view_pager_placeholder" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

编辑 2： 要解决滚动问题，请删除我在之前的编辑中建议的占位符。但是用库提供的RecyclerViewMaterialAdapter 包装你的 RecyclerView adpater

 mAdapter = new RecyclerViewMaterialAdapter(new CardAdapter());
 mRecyclerView.setAdapter(mAdapter);

完整代码：

fragment_recyclerview_advance.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="wrap_content"
    android:orientation="vertical">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

RecyclerViewFragment.java

public class RecyclerViewFragment extends Fragment {

    RecyclerView mRecyclerView;
    RecyclerView.LayoutManager mLayoutManager;
    RecyclerView.Adapter mAdapter;

    public static RecyclerViewFragment newInstance() {
        return new RecyclerViewFragment();
    }

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

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

        mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
        mRecyclerView.setHasFixedSize(true);

        mLayoutManager = new LinearLayoutManager(getActivity());
        mRecyclerView.setLayoutManager(mLayoutManager);

        mAdapter = new RecyclerViewMaterialAdapter(new CardAdapter());
        mRecyclerView.setAdapter(mAdapter);

        MaterialViewPagerHelper.registerRecyclerView(getActivity(), mRecyclerView, null);
    }

【讨论】：

这应该在编译期间而不是在运行时给出错误。
不..这些值存在于其他目录中（例如值-w820dp）..所以在编译时不会出错..但在运行时它会尝试访问默认值和如果找不到，应用程序将崩溃。
可能是这种情况，但你怎么知道它存在于 values-w820 或 etc 中？他还没有发布。
他正在使用来自this 库的示例应用程序。我在他们的示例应用程序中注意到了同样的错误（在 values-w820 中声明了 activity_horizontal_margin，但在默认值中没有声明）。我不能确定他是否犯了同样的错误。但值得一试。
太棒了。我想使用 GridLayoutManager 需要将 spanCount 传递给 RecyclerViewMaterialAdapter。所以mAdapter = new RecyclerViewMaterialAdapter(new CardAdapter(), 2);。你可以试试这个吗？

【解决方案2】：

检查您的代码后，我得到了解决方案。正如@Abhisheck 回答的那样。这是dimen声明的问题。将<dimen name="activity_horizontal_margin">64dp</dimen> 添加到dimen.xml 文件中。您还必须将您的样式从ActionBar 更改为NoActionBar。检查下面的编辑。

values/dimens.xml

<resources>
    <dimen name="cardMarginHorizontal">10dp</dimen>
    <dimen name="cardMarginVertical">8dp</dimen>
    <dimen name="activity_horizontal_margin">64dp</dimen>
</resources>

style.xml

<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">

您还需要升级您的依赖项。

build.gradle(示例)

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:recyclerview-v7:22.2.0'
    compile 'com.android.support:cardview-v7:22.2.0'
    compile 'com.android.support:support-v4:22.2.0'

    //compile ('com.github.florent37:materialviewpager:1.0.1@aar'){
    //    transitive=true
    //}

    compile project(':materialviewpager')
}

build.gradle(项目)

dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
        classpath 'com.github.dcendents:android-maven-plugin:1.2'
        classpath "com.jfrog.bintray.gradle:gradle-bintray-plugin:1.1"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

如果有什么问题请告诉我。

谢谢兄弟，我给了你赏金并勾选了你的答案有用，并接受了@Abhishek 的回答，因为他首先发现了这个问题，但对我来说，你们俩处于同一水平 - 那些喜欢帮助别人的人： )
找到任何解决方案，为什么 RecyclerView 隐藏 ViewPager ？
