我只需要接收字符串，它是与我单击的gridview项相关联的任何文本视图。
getItemAtPosition给了我一系列随机数，例如：Collectable @ c88c9b和SELECT * FROM TABLE_COLLECTION当我只需要单击的内容时，它仅将每行中的每个名称传递给我，请帮助我，我已经快完成了。
带有gridview的片段
public class CollectionFragment extends Fragment {
GridView gridView;
ArrayList<Collectable> list;
CollectionListAdapter adapter = null;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater,@Nullable ViewGroup container,@Nullable Bundle savedInstanceState) {
setHasOptionsMenu (true);
// inflater.inflate(R.layout.fragment_collection,container,false);
View view = inflater.inflate(R.layout.fragment_collection,null);
gridView = (GridView) view.findViewById(R.id.gridView);
list = new ArrayList<>();
//if (gridView != null) {
adapter = new CollectionListAdapter(getactivity().getapplicationContext(),R.layout.images_carousel,list);
gridView.setadapter(adapter);
//}
final Cursor cursor = ScannerPopup.sqLiteHelper.getData("SELECT * FROM TABLE_COLLECTION");
list.clear();
while(cursor.moveToNext()) {
int id = cursor.getInt(0);
String name = cursor.getString(1);
String box = cursor.getString(2);
String prod = cursor.getString(3);
String date = cursor.getString(4);
String store = cursor.getString(5);
String country = cursor.getString(6);
byte[] image = cursor.getBlob(7);
list.add(new Collectable(name,box,prod,date,store,country,image,id));
}
adapter.notifyDataSetChanged();
gridView.setOnItemClicklistener(new AdapterView.OnItemClicklistener() {
@Override
public void onItemClick(AdapterView<?> parent,View view,int position,long l) {
String clickedText = parent.getItemAtPosition(position).toString();
Cursor c = ScannerPopup.sqLiteHelper.getData("SELECT * FROM TABLE_COLLECTION");
while(c.moveToNext()) {
int id = c.getInt(0);
String name = c.getString(1);
String box = c.getString(2);
String prod = c.getString(3);
String date = c.getString(4);
String store = c.getString(5);
String country = c.getString(6);
byte[] image = c.getBlob(7);
Log.d("meme",clickedText);
Log.d("tag2",name);
}
}
});
