Ich habe eine Listenansicht, die ich die Zeilen über MySQL-Datenbank füllen.get imageview position innerhalb von listview
Dies ist eine Ansicht von dem, was ich getan habe:
Diese Namen, die Sie sah aus meiner Datenbank kommen, und die PLAY Image aus meiner Layoutliste ist, die in jeder Zeile erscheint (wenn ich eine Zeile in meine Datenbank hinzufüge).
Nun mein Problem ist, wenn ich einen Klick Zuhörer auf diese Play-Taste eingestellt, ändert sich weitere Play-Tasten aus einer anderen Reihen auch, aber nicht alle von ihnen (Zweck es in den Pause-Image usw. wechselt). Daher denke ich, ich bekomme die Position nicht, oder? Kannst du mir bitte dabei helfen?
Das ist mein Fragment:
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();
}
}
Das ist meine Produktklasse:
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;
}
Und das ist mein Adapter:
public class FunDapter<T> extends BaseAdapter implements Filterable {
private boolean paused = true;
protected List<T> mDataItems;
protected List<T> mOrigDataItems;
protected LongExtractor<T> idExtractor;

private int evenColorRes;

private Filter mFilter;
public FunDapter(Context context, List<T> dataItems, int layoutResource,
BindDictionary<T> dictionary) {
this(context, dataItems, layoutResource, null, dictionary);
}
public FunDapter(Context context, List<T> dataItems, int layoutResource,
LongExtractor<T> idExtractor, BindDictionary<T> dictionary) {
this.mContext = context;

}

holder.root = v;
holder.playPause=(ImageView)v.findViewById(R.id.playPause);
holder.playPause.setOnClickListener(new View.OnClickListener() {
@Override

holder.playPause.setImageResource(R.drawable.ic_pause);

}
else {

}
}});
FunDapterUtils.initViews(v, holder, mBindDictionary);
v.setTag(holder);
} else {

}
final T item = getItem(position);
showData(item, holder, position);
return v;
}
private void showData(T item, GenericViewHolder holder, int position) {

} else {

}
}
FunDapterUtils.showData(item, holder, position, mBindDictionary);
}
public FunDapter<T> setAlternatingBackground(int oddColorRes, int evenColorRes) {
if (oddColorRes <= 0 || evenColorRes <= 0) {
throw new IllegalArgumentException("Color parameters are illegal");
}
this.oddColorRes = oddColorRes;
this.evenColorRes = evenColorRes;
return this;
}
public void setIdExtractor(LongExtractor<T> idExtractor) {
this.idExtractor = idExtractor;
}
@Override
public Filter getFilter() {
return mFilter;
}
public void initFilter(FunDapterFilter<T> filter) {
if (filter == null)
throw new IllegalArgumentException("Cannot pass a null filter to FunDapter");
this.funDapterFilter = filter;
mFilter = new Filter() {
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
List<T> list = (List<T>) results.values;
if (results.count == 0) {
resetData();
} else {
mDataItems = list;
}
notifyDataSetChanged();
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
if (constraint == null || constraint.length() == 0) {
results.values = mOrigDataItems;
results.count = mOrigDataItems.size();
} else {
List<T> filter =
funDapterFilter.filter(constraint.toString(), mOrigDataItems);
results.count = filter.size();
results.values = filter;
}
return results;
}
};
}
public void resetData() {
mDataItems = mOrigDataItems;
}
}
Es ist eine Woche her, dass ich damit zu kämpfen habe, ich wäre so dankbar, wenn Sie mir dabei helfen würden.
