下面是我的代码片段:

v.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        int newPosition = MainActivity.mRecyclerView.getChildAdapterPosition(v);
        Intent cardViewIntent = new Intent(c, MainActivityCards.class);
        cardViewIntent.putExtra("Position", newPosition);
        c.startActivity(cardViewIntent);
    }
});

v是onCreateViewHolder的视图 c为背景信息

这个作品。

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

private final Context mContext;
private List<ServiceListModel> categoryList;
private View.OnClickListener onClickListener;

public ServiceListAdapter(Context mContext, List<ServiceListModel> categoryList, View.OnClickListener onClickListener) {
    this.categoryList = categoryList;
    this.mContext = mContext;
    this.onClickListener = onClickListener;
}

@Override
public ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
    final LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    final RowServiceListBinding binding = DataBindingUtil.inflate(inflater, R.layout.row_service_list, parent, false);
    return new ViewHolder(binding.getRoot(), binding);
}

@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
    holder.binding.rlService.setOnClickListener(onClickListener);
    holder.binding.rlService.setTag(position);
}

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

public class ViewHolder extends RecyclerView.ViewHolder {
    private final RowServiceListBinding binding;

    public ViewHolder(final View view, final RowServiceListBinding binding) {
        super(view);
        this.binding = binding;
    }

    @UiThread
    public void bind(final ServiceListModel mAddressModel) {
        //this.binding.setAddress(mAddressModel);
    }
}
}

在活动/片段中使用

ServiceListAdapter adapter = new ServiceListAdapter(context, serviceList, new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            switch (v.getId()) {
                case R.id.rlService:
                    int pos = (int) v.getTag();
                    serviceList.remove(position);
                    break;
            }
        }
    });

对我来说，最干净的方法就是这个。

适配器的构造函数

private class EnvironmentTypeRecyclerViewAdapter extends RecyclerView.Adapter<EnvironmentTypeRecyclerViewAdapter.ViewHolder>
{
     private final EnvironmentTypeRecyclerViewAdapterListener mEnvironmentTypeRecyclerViewAdapterListener;
     private List<Environment> mEnvironmentsData;

     public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
     {
         public ViewHolder(View v)
         {
             super(v);
             v.setOnClickListener(this);

         }

         @Override
         public void onClick(View v)
         {
              Environment environment = mEnvironmentsData.get(getAdapterPosition());
              if (mEnvironmentTypeRecyclerViewAdapterListener != null && environment != null) {
                      mEnvironmentTypeRecyclerViewAdapterListener.onListItemSelected(environment);      
              }
        }

        public EnvironmentTypeRecyclerViewAdapter(List<SmallCellEnvironment> environments, EnvironmentTypeRecyclerViewAdapterListener environmentTypeRecyclerViewAdapterListener)
        {
            mEnvironmentTypeRecyclerViewAdapterListener = environmentTypeRecyclerViewAdapterListener;
            mEnvironmentsData = environments;
        }
}

链接接口

private interface EnvironmentTypeRecyclerViewAdapterListener
{
    void onListItemSelected(Environment environment);
}

根据Yigit Boyar的说法，在RecyclerView上注册点击的最好方法是在ViewHolder的创建中定义点击，而不是仅仅为onBindViewHolder绑定的每个项目创建一个新的onClickListener

例子:

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): BaseViewHolder<*> {
   val itemBinding = LayoutInflater.from(context).inflate(R.layout.my_layout, parent, false)

   val vh = MainViewHolder (itemBinding)
   vh.itemView.setOnClickListener {
       val pos = vh.adapterPosition
       if(pos != NO_POSITION){
           itemClickLister.onCocktailClick(myList[pos],pos)
       }
   }

   return vh
}

以下是我所做的。这个解决方案同时支持onClick和onLongClick在两个RecyclerView项目和视图内的RecyclerView项目(内部视图)。

我在我选择的视图上标记viewHolder:

public RecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_item, null);
    ViewHolder viewHolder = new ViewHolder(itemView);

    itemView.setOnClickListener( this);
    itemView.setOnLongClickListener(this);
    viewHolder.imageIV.setOnClickListener(this);
    viewHolder.imageIV.setOnLongClickListener(this);

    viewHolder.imageIV.setTag(viewHolder);
    itemView.setTag(viewHolder);

    return viewHolder;
}

我使用holder.getPosition()在onClick()方法中检索位置(onLongClick类似):

public void onClick(View view) {
    ViewHolder holder = (ViewHolder) view.getTag();
    int position = holder.getPosition();

    if (view.getId() == holder.imageIV.getId()){
        Toast.makeText(context, "imageIV onClick at" + position, Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(context, "RecyclerView Item onClick at " + position, Toast.LENGTH_SHORT).show();
    }
}

带有getChildPosition的变体也可以工作。请注意，对于内部视图，在onClick()中使用:

int position = recyclerView.getChildPosition((View)view.getParent());

在我看来，这个解决方案的优点是，当一个人点击图像，只有onclick()图像侦听器被调用，而当我结合Jacob的解决方案为一个RecyclerView项目视图和我的解决方案为内部视图的RecyclerView项目视图onclick()也被调用(当点击图像)。

通常你在CardView中有多个元素，所以你需要一个布局视图来包装和组织它们。你可以添加一个OnClickListener到那个布局视图。1. 添加一个id到你的布局。在这个例子中是线性布局

<android.support.v7.widget.CardView
 .....>

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/card_view_linearLayout">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="name"
            android:id="@+id/card_view_name" />

        ...

    </LinearLayout>

</android.support.v7.widget.CardView>

2美元。在你的内部ViewHolder类中获取布局视图。

public static class ViewHolder extends RecyclerView.ViewHolder{
    private TextView nameView;
    ...
    private LinearLayout linearLayout;
    public ViewHolder(View itemView) {
        super(itemView);
        nameView = (TextView)itemView.findViewById(R.id.card_view_name);
        ...
        linearLayout = (LinearLayout)itemView.findViewById(R.id.card_view_linearLayout);
    }
}

3美元。将监听器添加到onBindViewHolder中的布局中，并使用回调将数据发送到活动或片段(未测试)。

@Override
public void onBindViewHolder(TrackAdapter.ViewHolder holder, final int position) {
    String str = mStringList.get(position);

    holder.nameView.setText(str);
    ...
    holder.linearLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            callback.itemCallback(mStringList.get(position));
        }
    });
}

如何使用回调是另一个故事
