检查这一个，我已经实现了所有的事情与适当的方式

RecyclerViewHolder类

public class RecyclerViewHolder extends RecyclerView.ViewHolder  {

    //view holder is for girdview as we used in the listView
    public ImageView imageView,imageView2;
    public RecyclerViewHolder(View itemView) {
        super(itemView);
        this.imageView=(ImageView)itemView.findViewById(R.id.image);
    }

}

适配器

public class RecyclerView_Adapter extends RecyclerView.Adapter<RecyclerViewHolder> {

    //RecyclerView will extend to recayclerview Adapter
    private ArrayList<ModelClass> arrayList;
    private Context context;
    private static RecyclerViewClickListener itemListener;
    //constructor of the RecyclerView Adapter
    RecyclerView_Adapter(Context context,ArrayList<ModelClass> arrayList,RecyclerViewClickListener itemListener){
        this.context=context;
        this.arrayList=arrayList;
        this.itemListener=itemListener;
    }

    @Override
    public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //this method will inflate the custom layout and return as viewHolder
        LayoutInflater layoutInflater=LayoutInflater.from(parent.getContext());
        ViewGroup mainGroup=(ViewGroup) layoutInflater.inflate(R.layout.single_item,parent,false);
        RecyclerViewHolder listHolder=new RecyclerViewHolder(mainGroup);

        return listHolder;
    }

    @Override
    public void onBindViewHolder(RecyclerViewHolder holder, final int position) {

        final ModelClass modelClass=arrayList.get(position);
        //holder
        RecyclerViewHolder mainHolder=(RecyclerViewHolder)holder;
        //convert the drawable image into bitmap
        Bitmap image= BitmapFactory.decodeResource(context.getResources(),modelClass.getImage());
        //set the image into imageView
        mainHolder.imageView.setImageBitmap(image);
        //to handle on click event when clicked on the recyclerview item and
        // get it through the RecyclerViewHolder class we have defined the views there
        mainHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //get the position of the image which is clicked
             itemListener.recyclerViewListClicked(v,position);
            }
        });

    }

    @Override
    public int getItemCount() {
        return (null!=arrayList?arrayList.size():0);
    }
}

的接口

public interface RecyclerViewClickListener {

    //this is method to handle the event when clicked on the image in Recyclerview
    public void recyclerViewListClicked(View v,int position);
}

//and to call this method in activity
RecyclerView_Adapter adapter=new RecyclerView_Adapter(Wallpaper.this,arrayList,this);
        recyclerView.setAdapter(adapter);
        adapter.notifyDataSetChanged();


    @Override
    public void  recyclerViewListClicked(View v,int position){

        imageView.setImageResource(wallpaperImages[position]);

    }

我喜欢这样，我正在用它

内部

public Adapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)

Put

View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.view_image_and_text, parent, false);
v.setOnClickListener(new MyOnClickListener());

在任何你想要的地方创建这个类

class MyOnClickListener implements View.OnClickListener {
    @Override
    public void onClick(View v) {
       int itemPosition = recyclerView.indexOfChild(v);
       Log.e("Clicked and Position is ",String.valueOf(itemPosition));
    }
}

我以前读过有一个更好的方法，但我喜欢这个方法，简单，不复杂。

我发现了使用androidx生命周期可变实时数据的最短方法之一

适配器:

private val onItemClickListener = MutableLiveData<YourAdapterItem>()


override fun onBindViewHolder(holder: GifsViewHolder, position: Int) {
    holder.itemView.setOnClickListener { onItemClickListener.value = gifs[position] }
}
fun getOnItemClickListener(): MutableLiveData<Gif> {
    return onItemClickListener
}

MainActivity的任何地方

    yourFancyAdapter.getOnItemClickListener().observe(this, Observer {
        println(it)
    })

这对我很管用。希望能有所帮助。最简单的方法。

内部视图Holder

class GeneralViewHolder extends RecyclerView.ViewHolder {
    View cachedView = null;

    public GeneralViewHolder(View itemView) {
        super(itemView);
        cachedView = itemView;
    }

内部OnBindViewHolder ()

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
            final GeneralViewHolder generalViewHolder = (GeneralViewHolder) holder;
            generalViewHolder.cachedView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(context, "item Clicked at "+position, Toast.LENGTH_SHORT).show();
                }
            });

如果你对这个解决方案有任何问题，请告诉我?

感谢@marmor，我更新了我的答案。

我认为在ViewHolder类构造函数中处理onClick()并通过OnItemClickListener接口将其传递给父类是一个很好的解决方案。

MyAdapter.java

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

private LayoutInflater layoutInflater;
private List<MyObject> items;
private AdapterView.OnItemClickListener onItemClickListener;

public MyAdapter(Context context, AdapterView.OnItemClickListener onItemClickListener, List<MyObject> items) {
    layoutInflater = LayoutInflater.from(context);
    this.items = items;
    this.onItemClickListener = onItemClickListener;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = layoutInflater.inflate(R.layout.my_row_layout, parent, false);
    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    MyObject item = items.get(position);
}

public MyObject getItem(int position) {
    return items.get(position);
}


class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    private TextView title;
    private ImageView avatar;

    public ViewHolder(View itemView) {
        super(itemView);
        title = itemView.findViewById(R.id.title);
        avatar = itemView.findViewById(R.id.avatar);

        title.setOnClickListener(this);
        avatar.setOnClickListener(this);
        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        //passing the clicked position to the parent class
        onItemClickListener.onItemClick(null, view, getAdapterPosition(), view.getId());
    }
}
}

适配器在其他类中的使用:

MyFragment.java

public class MyFragment extends Fragment implements AdapterView.OnItemClickListener {

private RecyclerView recycleview;
private MyAdapter adapter;

    .
    .
    .

private void init(Context context) {
    //passing this fragment as OnItemClickListener to the adapter
    adapter = new MyAdapter(context, this, items);
    recycleview.setAdapter(adapter);
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    //you can get the clicked item from the adapter using its position
    MyObject item = adapter.getItem(position);

    //you can also find out which view was clicked
    switch (view.getId()) {
        case R.id.title:
            //title view was clicked
            break;
        case R.id.avatar:
            //avatar view was clicked
            break;
        default:
            //the whole row was clicked
    }
}

}

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);
