Updated data for clicked row but scroll down the listview some row will also updated

I'm trying to update data for clicked row with dialog box. I can updated but when i scroll down some row will also updated. Then, when i scroll up again the data will random updated to other row.
Below is my adapter code:
public class ViewHolder {
TextView productid, productname, pcs, cs;
ImageView dist;
}
public List<Product_List> parkingList;
public Context context;
ArrayList<Product_List> arrayList;
private MyAppAdapter(List<Product_List> apps, Context context) {
this.parkingList = apps;
this.context = context;
arrayList = new ArrayList<Product_List>();
arrayList.addAll(parkingList);
}
#Override
public int getCount() {
return parkingList.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, final View convertView, ViewGroup parent) {
View rowView = convertView;
final MyAppAdapter.ViewHolder viewHolder;
if (rowView == null) {
LayoutInflater inflater = getLayoutInflater();
rowView = inflater.inflate(R.layout.productlist, parent, false);
viewHolder = new MyAppAdapter.ViewHolder();
viewHolder.productid = (TextView) rowView.findViewById(R.id.productid);
viewHolder.productname = (TextView) rowView.findViewById(R.id.productname);
viewHolder.pcs = (TextView) rowView.findViewById(R.id.pcs);
viewHolder.cs = (TextView) rowView.findViewById(R.id.cs);
viewHolder.dist = (ImageView) rowView.findViewById(R.id.dist);
rowView.setTag(viewHolder);
} else {
viewHolder = (MyAppAdapter.ViewHolder) convertView.getTag();
}
viewHolder.productid.setText(parkingList.get(position).getInvtID() + "");
viewHolder.productname.setText(parkingList.get(position).getDescr() + "");
final String a = viewHolder.productid.getText().toString();
final String b = viewHolder.productname.getText().toString();
if ( position % 2 == 0) {
rowView.setBackgroundColor(Color.parseColor("#FFFFFF"));
} else {
rowView.setBackgroundColor(Color.parseColor("#ECEAEA"));
}
rowView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
final Dialog dialog = new Dialog(context);
dialog.setTitle("Inventory Checking");
dialog.setContentView(R.layout.inventory);
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
final TextView productids = (TextView) dialog.findViewById(R.id.productids);
productids.setText(a);
final TextView productdesc = (TextView) dialog.findViewById(R.id.productdesc);
productdesc.setText(b);
final EditText pcss = (EditText) dialog.findViewById(R.id.pcss);
final EditText css = (EditText) dialog.findViewById(R.id.css);
final RadioButton btnyes = (RadioButton) dialog.findViewById(R.id.btnyes);
final RadioButton btnno = (RadioButton) dialog.findViewById(R.id.btnno);
btnno.setChecked(true);
Button btnsave = (Button) dialog.findViewById(R.id.btnsave);
btnsave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewHolder.pcs.setText(pcss.getText().toString());
viewHolder.cs.setText(css.getText().toString());
if (btnyes.isChecked()) {
viewHolder.dist.setImageResource(R.drawable.done);
} else {
viewHolder.dist.setImageResource(R.drawable.no);
}
notifyDataSetChanged();
dialog.dismiss();
}
});
dialog.show();
}
});
return rowView;
}
}
This is my adapter code.
String msg="Found";
ProgressDialog progress;
#Override
protected void onPreExecute() {
progress = ProgressDialog.show(InventoryChecking1.this, "Synchronising",
"Listview Loading! Please Wait...", true);
}
#Override
protected String doInBackground(String... strings) {
try {
Connection conn = connectionClass.CONN();
if (conn == null) {
success = false;
} else {
String query = "SELECT * FROM Inventory";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query);
if (rs != null) {
while (rs.next()) {
try {
if (rs.getString("Status").equals("A") || rs.getString("Status").equals("AC")) {
itemsArrayList.add(new Product_List(rs.getString("InvtID"), rs.getString("Descr"), rs.getString("Brand"),
rs.getString("Category")));
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
msg = "Found";
success = true;
} else {
msg = "No Data found!";
success = false;
}
}
} catch (Exception e) {
e.printStackTrace();
Writer writer = new StringWriter();
e.printStackTrace(new PrintWriter(writer));
msg = writer.toString();
success = false;
}
return msg;
}
#Override
protected void onPostExecute(String msg) {
progress.dismiss();
// Toast.makeText(SellerActivity.this, msg + "", Toast.LENGTH_LONG).show();
if (success == false) {
} else {
try {
myAppAdapter = new MyAppAdapter(itemsArrayList, InventoryChecking1.this);
listView.setAdapter(myAppAdapter);
} catch (Exception ex) {
}
}
}
}

Change data in list instead of UI Views just change in list and notify
the adapter:
btnsave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Product_List product_list = new Product_List(pcss.getText().toString(),css.getText().toString());
parkingList.set( position,product_list );
notifyDataSetChanged();
dialog.dismiss();
}
});

Spinner In Custom ListView Randomly Changed When Scrolling

I Just need to fix the value inside Spinner when i select some value and SetEnabled True/False when i checked the CheckBox.
For example when i check the chekcbox, the spinner will be enabled and do the opposite when i uncheck the checkbox.
However it will changing randomly when i just scrolling.
This my code :

}
});

In ListView when you scroll, the views are destroyed and re-created. To overcome the issue you need to preserve both of the checkbox status and spinner item's value.
For the checkbox, save the checked status from setOnClickListener inside a boolean array,
if (((CheckBox) v).isChecked()) {
checkBoxState[position] = true;
} else {
checkBoxState[position] = false;
}
The boolean array should like this,
private boolean[] checkBoxState;
Later on getView() apply the check/uncheck status of each checkbox items based on the array
holder.checkBox.setChecked(checkBoxState[position]);
Similarly to save the spinner data, create a Hashmap
Map<Integer, Integer> myMap = new HashMap<Integer, Integer>();
and save the spinner data once it's selected from the setOnItemSelectedListener
myMap.put(position, pos);
Later restore the spinner selection position from the saved data,
if (myMap.containsKey(position)) {
viewHolder.spinner.setSelection(myMap.get(position));
}

Update:
In order to make a select all/deselect all checkbox feature,
create a boolean flag at the top of adapter's class,
boolean isCheckAll = false;
then create a toggle method,
public void toggleCheckAll() {
isCheckAll = !isCheckAll;
for (int i = 0; i < listData.size(); i++) {
if (isCheckAll) {
checkBoxState[i] = true;
notifyDataSetInvalidated();
} else {
checkBoxState[i] = false;
notifyDataSetInvalidated();
}
}
}
Now call the method from your aactivity's check all button's click,
btnCheckAll.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
adapter.toggleCheckAll();
}
});

According to official documentation
It is not guaranteed that the convertView will have been previously created by getChildView(int, int, boolean, View, ViewGroup)
I think in this case you need to check
if (convertView != null && convertView.getTag() instance of Childnames) {
// reuse the convertView
else
// create new view
}

That is because you are mixing the View types, I think is probably from here:
#Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
#Override
public boolean hasStableIds() {
return true;
}
You should probably use unique ids for your children because this way they can be mixed up with the group ids.
