这就是我最后需要的东西，以防有人发现它有用:

public static class ViewHolder extends RecyclerView.ViewHolder {

    public ViewHolder(View item) {

        super(item);
        item.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("RecyclerView", "onClick：" + getAdapterPosition());
            }
        });

    }
}

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);
}

由于API已经发生了根本性的变化，如果你要为每个项目创建一个OnClickListener，这不会让我感到惊讶。不过也没那么麻烦。在你的RecyclerView的实现中。适配器<MyViewHolder>，你应该有:

private final OnClickListener mOnClickListener = new MyOnClickListener();

@Override
public MyViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.myview, parent, false);
    view.setOnClickListener(mOnClickListener);
    return new MyViewHolder(view);
}

onClick方法:

@Override
public void onClick(final View view) {
    int itemPosition = mRecyclerView.getChildLayoutPosition(view);
    String item = mList.get(itemPosition);
    Toast.makeText(mContext, item, Toast.LENGTH_LONG).show();
}

别白费力气了!这个特定用例的代码包含在Android Studio附带的Master/Detail Flow启动器项目中。

从Android Studio选择:

文件>新建>新建项目.... 在Phone and Tablet选项卡中选择如下所示的Master/Detail Flow。

用Kotlin或Java创建项目。 利润。

我不会在这里包括谷歌的ootb演示项目的代码，但我会概述谷歌提供的示例中的主要设计方法:

the item OnClickListener is created ONLY ONCE, and is assigned to a field in your RecyclerView.Adapter implementation. in the onBindViewHolder() you should set the same, pre-created onClickListener object on your ViewHolder instance with holder.itemView.setOnClickListener(mOnClickListener) (AVOID creating a new instance on every method call!); if you need to capture clicks on some specific elements inside the ViewHolder then extend ViewHolder and expose the elements you need as fields so that you can attach whatever listeners you need in onBindViewHolder() — and once again, do NOT re-create the listeners on every method call — initialise them as instance fields and attach them as needed. you can use .setTag() in order to pass state to your viewHolder, e.g. holder.itemView.setTag(mValues.get(position)); as used in the demo.

在Kotlin中也是如此

inner class MyViewHolder(v: View, myOnClickListener: MyOnClickListener) : RecyclerView.ViewHolder(v) {
    init {
        v.setOnClickListener { v -> myOnClickListener.onClick(v, adapterPosition) }
    }
}

override fun onCreateViewHolder(viewGroup: ViewGroup, viewType: Int): MyViewHolder {
    val view = LayoutInflater.from(viewGroup.context).inflate(R.layout.myview, viewGroup, false)
    return MyViewHolder(view, mOnClickListener)
}

inner class MyOnClickListener {
    fun onClick(view: View, position: Int) {
        val item = mList[position]
        Toast.makeText(view.context, item, Toast.LENGTH_LONG).show()
    }
}

这就是重用View的方法。OnClickListener:

public class TestAdapter extends RecyclerView.Adapter<TestAdapter.MyviewHolder>
    implements View.OnClickListener

在ViewHoder中获取项目布局的父视图:

public class MyviewHolder extends RecyclerView.ViewHolder {

    LinearLayout linearLayout;

    public MyviewHolder(View itemView) {
        super(itemView);
        linearLayout = itemView.findViewById(R.id.linear_layout_item);
    }
}

在onBindViewHolder中设置标签为位置:

@Override
public void onBindViewHolder(MyviewHolder holder, int position) {
    holder.linearLayout.setTag(position);
    holder.linearLayout.setOnClickListener(this);
}

在你的onClick实现中:

@Override
public void onClick(View v) {
    int position = (int) v.getTag();

    switch (v.getId()) {
        case R.id.linear_layout_item:
            // do some thing with position 
            break;
    }
}
