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

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();
}

这里有一个简单明了的方法是添加到您的ReacyclerView ViewHolder

public static class MyViewholder extends RecyclerView.ViewHolder {

    public MyViewholder(View itemView) {
        super(itemView);

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

    }
}

getAdapterPosition()返回当前被单击项的位置

有更简单的方法。只需要在根视图上应用onBindViewHolder中的click。

考虑这是你对适配器的看法，

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/linearlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

        <TextView
            android:id="@+id/textview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="1dp"
            android:textSize="15sp" />
</LinearLayout>

然后在适配器中执行以下操作

//get the layout and make view holder
@Override
public RVAdapter.ViewHolder1 onCreateViewHolder(ViewGroup parent, int viewType) {

    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter_layout, null);
    ViewHolder1 viewHolder = new ViewHolder1(view);
    return viewHolder;
}

@Override
public void onBindViewHolder(RVAdapter.ViewHolder1 holder, int position) {

    //apply on click on your root view
    holder.linearlayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Do on click stuff
        }
    });
}

//make references to views in layout including root view
public class ViewHolder1 extends RecyclerView.ViewHolder {

    protected LinearLayout linearlayout = null
    protected TextView textview = null;

    public CareerLinksViewHolder(View itemView) {
        super(itemView);

        this.linearlayout = (LinearLayout) itemView.findViewById(R.id.linearlayout);
        this.tvCompName = (TextView) itemView.findViewById(R.id.textview);
    }
}

将类标记为抽象并实现OnClick方法

public abstract class MainGridAdapter extends
    RecyclerView.Adapter<MainGridAdapter.ViewHolder> {
private List<MainListItem> mDataset;

// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public class ViewHolder extends RecyclerView.ViewHolder {
    // each data item is just a string in this case
    public TextView txtHeader;
    public TextView txtFooter;

    public ViewHolder(View v) {
        super(v);
        txtHeader = (TextView) v.findViewById(R.id.firstLine);
        txtFooter = (TextView) v.findViewById(R.id.secondLine);
    }
}

public void add(int position, MainListItem item) {
    mDataset.add(position, item);
    notifyItemInserted(position);
}

public void remove(MainListItem item) {
    int position = mDataset.indexOf(item);
    mDataset.remove(position);
    notifyItemRemoved(position);
}

// Provide a suitable constructor (depends on the kind of dataset)
public MainGridAdapter(List<MainListItem> myDataset) {
    mDataset = myDataset;
}

// Create new views (invoked by the layout manager)
@Override
public MainGridAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
        int viewType) {
    // create a new view
    View v = LayoutInflater.from(parent.getContext()).inflate(
            R.layout.list_item_grid_line, parent, false);
    // set the view's size, margins, paddings and layout parameters
    ViewHolder vh = new ViewHolder(v);
    return vh;
}

// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
    // - get element from your dataset at this position
    // - replace the contents of the view with that element     
    OnClickListener clickListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            onItemClicked(position);
        }
    };
    holder.itemView.setOnClickListener(clickListener);
    holder.txtHeader.setOnClickListener(clickListener);
    holder.txtFooter.setOnClickListener(clickListener);
    final MainListItem item = mDataset.get(position);
    holder.txtHeader.setText(item.getTitle());
    if (TextUtils.isEmpty(item.getDescription())) {
        holder.txtFooter.setVisibility(View.GONE);
    } else {
        holder.txtFooter.setVisibility(View.VISIBLE);
        holder.txtFooter.setText(item.getDescription());
    }
}

// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
    return mDataset.size();
}

public abstract void onItemClicked(int position);

}

在绑定事件中实现单击处理程序，使其只有一个事件实现

执行此:

mAdapter = new MainGridAdapter(listItems) {         
    @Override
    public void onItemClicked(int position) {
        showToast("Item Clicked: " + position, ToastPlus.STYLE_INFO);
    }
};

同样可以做长时间点击

我知道有很多答案，但我想我也可以提供我的实现。(完整的细节可以在我回答的另一个问题中找到)。

所以，要添加一个点击监听器，你的内部ViewHolder类需要实现View.OnClickListener。这是因为你将设置一个OnClickListener到ViewHolder的构造函数的itemView参数。让我来告诉你我的意思:

public class ExampleClickViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    TextView text1, text2;

    ExampleClickViewHolder(View itemView) {
        super(itemView);

        // we do this because we want to check when an item has been clicked:
        itemView.setOnClickListener(this);

        // now, like before, we assign our View variables
        title = (TextView) itemView.findViewById(R.id.text1);
        subtitle = (TextView) itemView.findViewById(R.id.text2);
    }

    @Override
    public void onClick(View v) {
        // The user may not set a click listener for list items, in which case our listener
        // will be null, so we need to check for this
        if (mOnEntryClickListener != null) {
            mOnEntryClickListener.onEntryClick(v, getLayoutPosition());
        }
    }
}

唯一需要添加的其他东西是适配器的自定义接口和setter方法:

private OnEntryClickListener mOnEntryClickListener;

public interface OnEntryClickListener {
    void onEntryClick(View view, int position);
}

public void setOnEntryClickListener(OnEntryClickListener onEntryClickListener) {
    mOnEntryClickListener = onEntryClickListener;
}

这样，新的支持单击的适配器就完成了。

现在，让我们用它…

    ExampleClickAdapter clickAdapter = new ExampleClickAdapter(yourObjects);
    clickAdapter.setOnEntryClickListener(new ExampleClickAdapter.OnEntryClickListener() {
        @Override
        public void onEntryClick(View view, int position) {
            // stuff that will happen when a list item is clicked
        }
    });

这基本上就是设置普通适配器的方法，除了使用您创建的setter方法来控制当用户单击特定列表项时要做什么。
