我有一個列表視圖，我通過mysql數據庫填充行。在列表視圖中獲取imageview位置
這就是我所做的一個觀點：出現在每一行中
這個名字你看到從我的數據庫來和PLAY ImageView的是從我的佈局列表（當我添加一行到我的數據庫）。
現在我的問題是，當我設置一個點擊偵聽器，該播放按鈕，（目的是切換到暫停ImageView等）它改變另一個播放按鈕從其他行，但不是所有的人。因此，我認爲我沒有得到這個位置，對吧？你能幫我解決這個問題嗎？
這是我的片段：
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();
}
}
這是我的產品類別：
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;
}
這是我的適配器：

我一直在努力爭取這一週，如果你能幫助我，我會非常感激。
