Question

我现在尝试了很多不同的方法，但我还没有成功地将onclick方法应用到我的recycleview。我的recycleview正在工作并显示我的项目。

有人可以协助我在我的recycleview中实现Onclick方法吗？

提前谢谢。

这是我的适配器：

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private ItemData[] itemsData;
public OnClickListener mOnClickListener;

public MyAdapter(ItemData[] itemsData) {
    this.itemsData = itemsData;
}

// Create new views (invoked by the layout manager)
@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                               int viewType) {
    // create a new view
    View itemLayoutView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.item_layout, null);

    // create ViewHolder

    ViewHolder viewHolder = new ViewHolder(itemLayoutView);
    return viewHolder;
}

// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {



viewHolder.txtViewTitle.setText(itemsData[position].getTitle());
    viewHolder.imgViewIcon.setImageResource(itemsData[position].getImageUrl());


}

// inner class to hold a reference to each item of RecyclerView
public static class ViewHolder extends RecyclerView.ViewHolder {

    public TextView txtViewTitle;
    public ImageView imgViewIcon;

    public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);
        txtViewTitle = (TextView) itemLayoutView.findViewById(R.id.item_title);
        imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.item_icon);
    }
}

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

以下是项目数据：

public class ItemData {

private String title;
private int imageUrl;

public ItemData(String title,int imageUrl){

    this.title = title;
    this.imageUrl = imageUrl;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public int getImageUrl() {
    return imageUrl;
}

我的Fragment创建项目的位置：

public class MyMedicinFrag extends Fragment {

@Override
public View onCreateView(LayoutInflater i, ViewGroup container, Bundle savedInstanceState) {
    View rod = i.inflate(R.layout.fragment_mymedicin, container, false);


    RecyclerView recyclerView = (RecyclerView) rod.findViewById(R.id.recyclerView);
    FloatingActionButton fabBtn = (FloatingActionButton) rod.findViewById(R.id.fab);
    fabBtn.show();

    ItemData itemsData[] = {
            new ItemData("Panodil 500 mg", R.drawable.panodil),
            new ItemData("Ipren 200 mg", R.drawable.ipren),
            new ItemData("Madopar 200 mg", R.drawable.madopar),
            new ItemData("Diclofenac 50 mg", R.drawable.diclofenac),
            new ItemData("Allopurinol 300 mg", R.drawable.allopurinol)
    };

    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

    MyAdapter mAdapter = new MyAdapter(itemsData);
    recyclerView.setAdapter(mAdapter);
    recyclerView.setItemAnimator(new DefaultItemAnimator());

    return rod;

}}

您onCreateViewHolder()中的

使用此代码：

View view = LayoutInflater.from(mContext).inflate(R.layout.myview, parent, false);

        view.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
                //do something on click
                }
            }
        });

使用onclick帮助进行Recycleview
