我有一个RecyclerViewAdapter用StoreName，image等填充我的List，我有listitems.ok的模型，我从ListView迁移到recylerview。我想点击任何项目并获取项目数据（如商店名称）和意图到另一个活动，现在问题是，当我点击项目时，它给出了错误的商店名称。但是当我使用提供正确输入的onItemclickListener时。我会告诉你..
这是我的 RecyclerViewAdapter 。
public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private List<StoresItem> mDataset;
private static MyClickListener myClickListener;
Context context;
Bitmap xx;
public MyRecyclerViewAdapter(Context context, List<StoresItem> myDataset)
{
mDataset = myDataset;
}
public static class DataObjectHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView txtStoreName,txtDeliveryTime;
ImageView storeImg;
RatingBar ratingBar;
public DataObjectHolder(View itemView)
{
super(itemView);
txtStoreName = (TextView) itemView.findViewById(R.id.txtStoreName);
txtDeliveryTime = (TextView) itemView.findViewById(R.id.txtDeliveryTime);
storeImg = (ImageView) itemView.findViewById(R.id.storeImg);
ratingBar=(RatingBar)itemView.findViewById(R.id.ratingBar);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
}
@Override
public void onClick(View v)
{
myClickListener.onItemClick(getLayoutPosition(), v);
}
}
public void setOnItemClickListener(MyClickListener myClickListener)
{
this.myClickListener = myClickListener;
}
@Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent, int viewType)
{
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.storelist, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
return dataObjectHolder;
}
@Override
public void onBindViewHolder(DataObjectHolder holder, int position)
{
ImageView storeImg;
holder.txtStoreName.setText(mDataset.get(position).gettxtStoreName().toString());
holder.txtDeliveryTime.setText(mDataset.get(position).gettxtDeliveryTime().toString());
holder.ratingBar.setFocusable(false);
int loader = R.drawable.image;
String url = mDataset.get(position).getstoreImg().toString();
ImageLoader imgLoader = new ImageLoader(context);
imgLoader.DisplayImage(url,loader,holder.storeImg);
}
public void addItem(StoresItem dataObj, int index) {
mDataset.add(dataObj);
notifyItemInserted(index);
}
public void deleteItem(int index) {
mDataset.remove(index);
notifyItemRemoved(index);
}
@Override
public int getItemCount() {
return mDataset.size();
}
public interface MyClickListener
{
public void onItemClick(int position, View v);
}
public Object getItem(int position)
{
return mDataset.get(position);
}
@Override
public long getItemId(int position)
{
return mDataset.indexOf(getItem(position));
}
@Override
public int getItemViewType(int position)
{
return super.getItemViewType(position);
}
}
这是我的 StoreModel 。
public class StoresItem
{
private String txtStoreName, txtDeliveryTime, storeImg;
public StoresItem(String txtStoreName, String txtDeliveryTime,String storeImg)
{
this.txtStoreName = txtStoreName;
this.txtDeliveryTime = txtDeliveryTime;
this.storeImg = storeImg;
}
public String gettxtStoreName()
{
return txtStoreName;
}
public void settxtStoreName(String txtStoreName)
{
this.txtStoreName = txtStoreName;
}
public String gettxtDeliveryTime()
{
return txtDeliveryTime;
}
public void settxtDeliveryTime(String txtDeliveryTime)
{
this.txtDeliveryTime = txtDeliveryTime;
}
public String getstoreImg()
{
return storeImg;
}
public void setstoreImg(String storeImg)
{
this.storeImg = storeImg;
}
}
这是我的片段，我使用 onclickListner 。

okk ... recyclerviews存在问题 - onItemclicklister因为列表视图 - onItemCLicklistner()
提供Adapterview，我可以像这样使用parent.getItematposition(position)来获取项目。
storeListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
StoresItem storesItems = (StoresItem) parent.getItemAtPosition(position);
Bundle args = new Bundle();
Intent in = new Intent(getActivity(), ProductActivity.class);
args.putString("SelectedStoreName", storesItems.gettxtStoreName().toString());
in.putExtras(args);
startActivity(in);
}
});
可以任何人告诉我什么是getWrong StoreName的原因。??
答案 0 :(得分：0)
您正在使用myClickListener.onItemClick(getLayoutPosition(), v);，您必须使用myClickListener.onItemClick(getAdapterPosition(), v);
