When checkboxes are checked and text inserted into edittext in listvew they seem to migrate between listitems somewhat randomly both when scrolling and not scrolling.
I have tried to implement holders and other solutions that can be found in the following links but to no avail.
CheckBox in RecyclerView keeps on checking different items
Checking a checkbox in listview makes other random checkboxes checked too
Any and all suggestions on my predicament would be greatly appreciated.
Here is the code from the aforementioned program.
ItemAdapter
public class ItemAdapter extends ArrayAdapter<Item> {
public static boolean isitpopulated;
public static int DrawerInUse;
public static int ListLoc;
public ItemAdapter(Activity context, ArrayList<Item> items) {
super(context, 0, items);
}
@Override
public View getView(final int position, final View convertView, final ViewGroup parent) {
// Check if the existing view is being reused, otherwise inflate the view
View listItemView = convertView;
if (listItemView == null) {
listItemView = LayoutInflater.from(getContext()).inflate(
R.layout.list_item, parent, false);
}
// Get the {@link Item} object located at this position in the list
final Item currentItem = getItem(position);
final Item currentposs = getItem(position);
// Find the TextView in the list_item.xml layout with the ID version_name
TextView itemTextView = (TextView) listItemView.findViewById(R.id.item);
CheckBox check = listItemView.findViewById(R.id.checkbox);
final TextView quantityTextView = (TextView) listItemView.findViewById(R.id.quantity);
String listcontent = quantityTextView.getText().toString();
int drawer = Drawers.DrawerChosen;
// Get the version name from the current object and
// set this text on the name TextView
itemTextView.setText(currentItem.getItem());
TextView infoTextView = (TextView) listItemView.findViewById(R.id.info);
infoTextView.setText(currentItem.getInfo());
TextView doseTextView = (TextView) listItemView.findViewById(R.id.dose);
doseTextView.setText(currentItem.getDose());
TextView typeTextView = (TextView) listItemView.findViewById(R.id.type);
typeTextView.setText(currentItem.getType());
