When I run my app, all the checkboxes are checked in my ListView but I don't want them checked at the start.
I think I didn't write onDestroy() correctly.
Please help me!
Here is my code:
Adapter:
public abstract class PlanetAdapter extends ArrayAdapter<Planet> implements CompoundButton.OnCheckedChangeListener {
private List<Planet> planetList = null;
private Context context = null;
ArrayList<Birra> objects;
private HashMap<Integer, Planet> pizzaSelected = new HashMap<>();
public boolean Checked;
public PlanetAdapter(List<Planet> planetList, Context context) {
super(context, R.layout.single_listview_item, planetList);
this.planetList = planetList;
this.context = context;
}
public class PlanetHolder {
public TextView planetName;
public TextView distView;
public TextView valuta;
public CheckBox chkBox;
public EditText edit;
//public String quantità;
public boolean checked;
public TextView id;
}
@Override
public int getCount() {
return planetList.size();
}
@Override
public Planet getItem(int position) {
return planetList.get(position);
}
@Override
public long getItemId(int position) {
return planetList.get(position).getId();
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row = convertView;
PlanetHolder holder = null;
if (row == null) {

row = inflater.inflate(R.layout.single_listview_item, parent, false);

holder.edit.setEnabled(false);
// holder.id = (TextView) row.findViewById(R.id.id);
row.setTag(holder);
} else {
holder = (PlanetHolder) row.getTag();
}
final Planet p = planetList.get(position);
holder.planetName.setText(p.getName());
holder.distView.setText("" + p.getDistance());
holder.valuta.setText("" + p.getValuta());
holder.chkBox.setChecked(p.isSelected());
holder.chkBox.setTag(p);
