Android:RecyclerView 点击监听器未进入适配器

Question

我有一个包含 600 个项目的数组。我已将所有数组项放在 RecyclerView 中，它们滚动得很好。但是，当我尝试访问 onClick 监听器时，它没有被调用。我还尝试在我的 ViewHolder 类中实现 View.OnClickListener 和重写 onClick，但它不起作用。

我想在用户单击 View 中的某个项目时 Toast 列表中被单击项目的数据

适配器代码是

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

public static class ViewHolder extends RecyclerView.ViewHolder
    implements View.OnClickListener {
private String mItem;
private TextView mTextView;

public ViewHolder(View view) {
    super(view);
    view.setOnClickListener(this);
    mTextView = (TextView) view.findViewById(R.id.item_title);
}

public void setItem(String item) {
    mItem = item;
    mTextView.setText(item);
}

@Override
public void onClick(View view) {
    Log.d("TAG", "onClick " + getPosition() + " " + mItem);
}
}

 private String[] mDataset;

 public MyAdapter(String[] dataset) {
  mDataset = dataset;
}

@Override
 public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
        .inflate(R.layout.item, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
  }

@Override
 public void onBindViewHolder(ViewHolder holder, int position) {
  holder.setItem(mDataset[position]);
  }

@Override
public int getItemCount() {
 return mDataset.length;
 }
}

Try this..

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

  public static class ViewHolder extends RecyclerView.ViewHolder
           {
    private String mItem;
    private TextView mTextView;

    public ViewHolder(View view) {
      super(view);
      mTextView = (TextView) view.findViewById(R.id.item_title);


    }

    public void setItem(String item) {
      mItem = item;
      mTextView.setText(item);
    }

    private String[] mDataset;
Context context;
    public MyAdapter(Context context,String[] dataset) {
    this.context=context;
      mDataset = dataset;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
      View v = LayoutInflater.from(parent.getContext())
              .inflate(R.layout.item, parent, false);
      ViewHolder vh = new ViewHolder(v);
      return vh;
    }

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

    holder.setOnClickListener(new ItemClicklistener(position);
      holder.setItem(mDataset[position]);
    }

    @Override
    public int getItemCount() {
      return mDataset.length;
    }


      class ItemClicklistener implements View.OnClickListener {
        private  int position;

        ItemClicklistener(int position) {

            this.position = position;
        }

        @Override
        public void onClick(View view) {
           Toast.makeText(context,"OnClick :"+position,Toast.LENGTH_SHORT).show();


        }
    }


  }
