imageview konumu içinde görünüm görünümüne geçin

Question

Satırları mysql veritabanı aracılığıyla doldurduğum bir Liste görünümü var. Her satırda görünen sen testere benim veritabanından geliyor

Bu isimler ve ImageView benim düzen listeden olduğu OYUN (:

Bu

Yaptığım şeyin bir görünümüdür veritabanına bir satır eklediğimde). Ben (amaç duraklama ImageView vb içine geçiriliyor) Çok başka satırlardan başka oynatma düğmelerini değiştirir, ancak hepsi değil, o oynat düğmesinin bir tıklama işleyicisi ayarladığınızda

Şimdi benim sorundur. Bu yüzden pozisyonu alamadığımı düşünüyorum, değil mi? Bu konuda bana yardımcı olabilir misiniz lütfen! Bu benim Ürün sınıfı

public class XXXUpdatesFragment extends Fragment implements AsyncResponse 
,AdapterView.OnItemClickListener{ 

    View view ; 
    private ArrayList<Product> productList; 
    private ListView lvProduct; 
    private FunDapter<Product> adapter; 

    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     view = inflater.inflate(R.layout.xxx_updates_layout, container, false); 
     ImageLoader.getInstance().init(UILConfig.config(getActivity())); 

     lvProduct = (ListView)view.findViewById(R.id.lvProduct); 

     PostResponseAsyncTask taskRead = new PostResponseAsyncTask(getActivity(), this); 

     taskRead.execute("http://symphonyrecords.6te.net/product.php"); 

     return view; 

    } //onCreate 


    @Override 
    public void processFinish(String s) { 
     productList = new JsonConverter<Product>().toArrayList(s, Product.class); 

     BindDictionary<Product> dict = new BindDictionary<Product>(); 
     dict.addStringField(R.id.tvName, new StringExtractor<Product>() { 
      @Override 
      public String getStringValue(Product product, int position) { 
       return product.name; 
      } 
     }); 

     dict.addStringField(R.id.tvDescription, new StringExtractor<Product>() { 
      @Override 
      public String getStringValue(Product product, int position) { 
       return product.description; 
      } 
     }); 

     dict.addStringField(R.id.tvQty, new StringExtractor<Product>() { 
      @Override 
      public String getStringValue(Product product, int position) { 
       return "" + product.qty; 
      } 
     }); 


     adapter = new FunDapter<>(getActivity(), productList, R.layout.d_layout_list_d, dict); 


     lvProduct.setAdapter(adapter); 
     lvProduct.setOnItemClickListener(this); 
    } 

    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
     Product selectedProduct = productList.get(position); 
     Toast.makeText(getActivity(),selectedProduct.name+"", Toast.LENGTH_SHORT).show(); 
     } 


    } 

geçerli::

Bu

benim Fragment olduğunu

public class Product implements Serializable { 
@SerializedName("pid") 
public int pid; 

@SerializedName("name") 
public String name; 

@SerializedName("qty") 
public int qty; 

@SerializedName("price") 
public String description;

Bununla uğraştığım bir hafta oldu, bana yardım edersen çok minnettar olurdum.

modeli sınıfında tek Paramtre ekleyin ve başlangıçta FunDapter sınıfta sıfır

olarak ayarlayın:

holder.playPause=(ImageView)v.findViewById(R.id.playPause); 

    if(mDataItems.get(position).getplayPauseFlag()==1) 
    { 
     holder.playPause.setImageResource(R.drawable.ic_pause); 
    } 
    else 
    { 
     holder.playPause.setImageResource(R.drawable.ic_play); 
    } 


    holder.playPause.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 

       if (mDataItems.get(position).getplayPauseFlag()==0) 
       { 
        mDataItems.get(position).setplayPauseFlag(1); 
       } 
       else { 
        mDataItems.get(position).setplayPauseFlag(0); 
       } 
       notifyDataSetChanged(); 
    }});
