如何把它们放在一起举例…

onClick() handling Cursor - RecyclerView ViewHolder types public class OrderListCursorAdapter extends CursorRecyclerViewAdapter<OrderListCursorAdapter.ViewHolder> { private static final String TAG = OrderListCursorAdapter.class.getSimpleName(); private static final int ID_VIEW_HOLDER_ACTUAL = 0; private static final int ID_VIEW_HOLDER = 1; public OrderListCursorAdapter(Context context, Cursor cursor) { super(context, cursor); } public static class ViewHolderActual extends ViewHolder { private static final String TAG = ViewHolderActual.class.getSimpleName(); protected IViewHolderClick listener; protected Button button; public ViewHolderActual(View v, IViewHolderClick listener) { super(v, listener); this.listener = listener; button = (Button) v.findViewById(R.id.orderList_item_button); button.setOnClickListener(this); } public void initFromData(OrderData data) { Log.d(TAG, "><initFromData(data=" + data + ")"); orderId = data.getId(); vAddressStart.setText(data.getAddressStart()); vAddressEnd.setText(data.getAddressEnd()); } @Override public void onClick(View view) { if (view instanceof Button) { listener.onButtonClick((Button) view, getPosition(), this); } else { super.onClick(view); } } public interface IViewHolderClick extends ViewHolder.IViewHolderClick { public void onButtonClick(Button button, int position, ViewHolder viewHolder); } } public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { private static final String TAG = ViewHolder.class.getSimpleName(); protected long orderId; protected IViewHolderClick listener; protected TextView vAddressStart; protected TextView vAddressEnd; protected TextView vStatus; public ViewHolder(View v, IViewHolderClick listener) { super(v); this.listener = listener; v.setOnClickListener(this); vAddressStart = (TextView) v.findViewById(R.id.addressStart); vAddressEnd = (TextView) v.findViewById(R.id.addressEnd); vStatus = (TextView) v.findViewById(R.id.status); } public void initFromData(OrderData data) { Log.d(TAG, "><initFromData(data=" + data + ")"); orderId = data.getId(); vAddressStart.setText(data.getAddressStart()); vAddressEnd.setText(data.getAddressEnd()); } public long getOrderId() { return orderId; } @Override public void onClick(View view) { listener.onCardClick(view, getPosition(), this); } public interface IViewHolderClick { public void onCardClick(View view, int position, ViewHolder viewHolder); } } @Override public int getItemViewType(int position) { return position == 0 ? ID_VIEW_HOLDER_ACTUAL : ID_VIEW_HOLDER; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { Log.d(TAG, ">>onCreateViewHolder(parent=" + parent + ", viewType=" + viewType + ")"); ViewHolder result; switch (viewType) { case ID_VIEW_HOLDER_ACTUAL: { View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_layout_actual, parent, false); result = new ViewHolderActual(itemView, new ViewHolderActual.IViewHolderClick() { @Override public void onCardClick(View view, int position, ViewHolder viewHolder) { Log.d(TAG, "><onCardClick(view=" + view + ", position=" + position + ", viewHolder=" + viewHolder + ")"); Intent intent = new Intent(view.getContext(), OrderDetailActivity.class); intent.putExtra(OrderDetailActivity.ARG_ORDER_ID, viewHolder.getOrderId()); view.getContext().startActivity(intent); } @Override public void onButtonClick(Button button, int position, ViewHolder viewHolder) { Log.d(TAG, "><onButtonClick(button=" + button + ", position=" + position + ", viewHolder=" + viewHolder + ")"); Intent intent = new Intent(button.getContext(), OrderMapActivity.class); intent.putExtra(OrderMapActivity.ARG_ORDER_ID, viewHolder.getOrderId()); button.getContext().startActivity(intent); } }); break; } case ID_VIEW_HOLDER: default: { View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_layout, parent, false); result = new ViewHolder(itemView, new ViewHolder.IViewHolderClick() { @Override public void onCardClick(View view, int position, ViewHolder viewHolder) { Log.d(TAG, "><onCardClick(view=" + view + ", position=" + position + ", viewHolder=" + viewHolder + ")"); Intent intent = new Intent(view.getContext(), OrderDetailActivity.class); intent.putExtra(OrderDetailActivity.ARG_ORDER_ID, viewHolder.getOrderId()); view.getContext().startActivity(intent); } }); break; } } Log.d(TAG, "<<onCreateViewHolder(parent=" + parent + ", viewType=" + viewType + ")= " + result); return result; } @Override public void onBindViewHolder(ViewHolder viewHolder, Cursor cursor) { Log.d(TAG, "><onBindViewHolder(viewHolder=" + viewHolder + ", cursor=" + cursor + ")"); final OrderData orderData = new OrderData(cursor); viewHolder.initFromData(orderData); } }

据我所知，MLProgrammer-CiM的答案很简单，可以这样做:

class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    private ImageView image;
    private TextView title;
    private TextView price;

    public MyViewHolder(View itemView) {
        super(itemView);
        image = (ImageView)itemView.findViewById(R.id.horizontal_list_image);
        title = (TextView)itemView.findViewById(R.id.horizontal_list_title);
        price = (TextView)itemView.findViewById(R.id.horizontal_list_price);
        image.setOnClickListener(this);
        title.setOnClickListener(this);
        price.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        Toast.makeText(context, "Item click nr: "+getLayoutPosition(), Toast.LENGTH_SHORT).show();
    }
}

最简单的方法如下:

在Adapter类开始时声明全局变量:

// Store out here so we can resuse
private View yourItemView;

然后在onBindViewHolder方法中设置OnClickListener:

@Override
public void onBindViewHolder(BusinessAdapter.ViewHolder holder, int position) {

    // Set up the on click listener
    yourItemView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(mContext,Integer.toString(position),Toast.LENGTH_SHORT).show();
        }
    });

}

其他答案都不正确。

RecyclerView是如何不同于Listview?

一个区别是有一个LayoutManager类和RecyclerView，通过它你可以像-一样管理你的RecyclerView

水平或垂直滚动线性layoutmanager GridLayout by GridLayoutManager 交错网格布局由StaggeredGridLayoutManager

就像水平滚动的RecyclerView-

LinearLayoutManager llm = new LinearLayoutManager(context);
llm.setOrientation(LinearLayoutManager.HORIZONTAL);
recyclerView.setLayoutManager(llm);

修改了我的评论…

public class MyViewHolder extends RecyclerView.ViewHolder {

        private Context mContext;

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

            mContext = itemView.getContext();

            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

                    int itemPosition = getLayoutPosition();
                    Toast.makeText(mContext, "" + itemPosition, Toast.LENGTH_SHORT).show();

                }
            });
        }

Recyclerview动画没有经过测试，其他正常。我认为它已经优化到最大。接口有其他用途，可以暂时忽略。

public abstract class BaseAdapterRV<VH extends BaseViewHolder> extends RecyclerView.Adapter<VH> implements AdapterInterface {
    public final String TAG = getClass().getSimpleName();

    protected final Activity mActivity;
    protected final LayoutInflater mInflater;
    protected ItemClickInterface<?, Integer> mListener;

    public BaseAdapterRV(Activity activity) {
        mActivity = activity;
        mInflater = LayoutInflater.from(mActivity);
    }

    @Override
    public final VH onCreateViewHolder(ViewGroup parent, int viewType) {
        return onCreateViewHolder(parent, viewType, mInflater);
    }

    @Override
    public final void onBindViewHolder(VH holder, int position) {
        holder.itemView.setTag(R.id.tag_view_click, position);
        //创建点击事件
        holder.itemView.setOnClickListener(mListener);
        holder.itemView.setOnLongClickListener(mListener);
        onBindVH(holder, position);
    }


    ///////////////////////////////////////////////////////////////////////////
    // 以下是增加的方法
    ///////////////////////////////////////////////////////////////////////////

    /**
     * 注意!涉及到notifyItemInserted刷新时立即获取position可能会不正确
     * 里面也有onItemLongClick
     */
    public void setOnItemClickListener(ItemClickInterface<?, Integer> listener) {
        mListener = listener;
        notifyDataSetChanged();
    }

    @NonNull
    protected abstract VH onCreateViewHolder(ViewGroup parent, int viewType, LayoutInflater inflater);

    protected abstract void onBindVH(VH holder, int position);

}

这是接口

/**
 * OnItemClickListener的接口
 * 见子类实现{@link OnItemClickListener}{@link OnItemItemClickListener}
 */
public interface ItemClickInterface<DATA1, DATA2> extends View.OnClickListener, View.OnLongClickListener {

    void onItemClick(DATA1 data1, DATA2 data2);

    boolean onItemLongClick(DATA1 data1, DATA2 data2);
}

这是一个抽象类

public abstract class OnItemClickListener<DATA> implements ItemClickInterface<View, DATA> {
    @Override
    public void onClick(View v) {
        onItemClick(v, (DATA) v.getTag(R.id.tag_view_click));
    }

    @Override
    public boolean onLongClick(View v) {
        return onItemLongClick(v, (DATA) v.getTag(R.id.tag_view_click));
    }

    @Override
    public boolean onItemLongClick(View view, DATA data) {
        return false;
    }
}

你只需要它

    mAdapter.setOnItemClickListener(new OnItemClickListener<Integer>() {
        @Override
        public void onItemClick(View view, Integer integer) {

        }

        @Override
        public boolean onItemLongClick(View view, Integer integer) {
            return true;
        }
    });
