sto usando un GridView
all'interno di un ExpandableListView
Cercando di deselezionare una vista utilizzando getChildAt()
Ho una funzione che mette in evidenza un elemento quando si fa clic, ora sto cercando di implementare un pulsante che se premuto sarà deselezionare tutti gli elementi selezionati, ma è Deselezionando solo l'ultima vista fatto clic
public class GridAdapter extends BaseAdapter {
private Context mContext;
private ArrayList<Filhos> child;
public ArrayList<CadastraEscolas> escola;
private ArrayList<ArrayList<Filhos>> filhos = new ArrayList();
public GridAdapter(Context context, ArrayList<CadastraEscolas> groups, ArrayList<Filhos> childValues, int groupPosition) {
mContext = context;
child = childValues;
escola = groups;
posicaoEscola = groupPosition;
}
@Override
public int getCount() {
return child.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int arg0) {
return 0;
}
@Override
public View getView(final int position, View convertView, final ViewGroup parent) {
holder = null;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.child_item, null);
holder = new ViewHolder();
final TextView idAluno = (TextView) convertView.findViewById(R.id.idcrianca);

convertView.setTag(holder);
final View finalConvertView = convertView;
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (list.size() > 0) {
isChecked = filhos.get(posicaoEscola).get(position).isChecked();
if (!isChecked) {
selecao(true, position, nomeAluno, 0xFFFFFFFF, finalConvertView, View.VISIBLE);
} else {

limpaSelecao(false, position, nomeAluno, 0xFFD5672B, parent, View.GONE);
}
});
}
});
} else {

}
holder.text.setText(child.get(position).getNome());
return convertView;

public void selecao(boolean check, int position, TextView nomeAluno, int color, View v, int visibility) {

}

}
}
}
}
Disposizione:
<RelativeLayout

android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@drawable/nomealuno_main"

<View

</RelativeLayout>
qui è che cosa è succedendo g:
quando seleziono tutti gli elementi da A a B in quel modo:
e ha colpito chiaro, rimuoverà solo i bambini selezionati tra l'ultimo gruppo che ho cliccato:
Devo rimuoverli tutti quando faccio clic su Cancella, tutti i bambini non importa in quale gruppo devono essere rimossi.
