我使用一個視圖GridView內的ExpandableListView試圖取消使用getChildAt（）
我有一個突出被點擊時，它的項目的功能，現在我想實現一個按鈕，按下時它會取消選擇所有選定的項目，但它取消選擇只有最後單擊了看法
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);
final TextView nomeAluno = (TextView) convertView.findViewById(R.id.name);
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 {
selecao(false, position, nomeAluno, 0xFFD5672B, finalConvertView, View.GONE);
}
ex.findViewById(R.id.notificar).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
limpaSelecao(false, position, nomeAluno, 0xFFD5672B, parent, View.GONE);
}
});
}
});
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.text.setText(child.get(position).getNome());
return convertView;
}
static class ViewHolder {
TextView text;
}
public void selecao(boolean check, int position, TextView nomeAluno, int color, View v, int visibility) {
filhos.get(posicaoEscola).get(position).setChecked(check);
nomeAluno.setTextColor(color);
v.findViewById(R.id.overlay).setVisibility(visibility);
v.findViewById(R.id.overlayText).setVisibility(visibility);
}
public void limpaSelecao(boolean check, int position, TextView nomeAluno, int color, ViewGroup v, int visibility) {
for (int x = 0; x < group.size(); x++) {
for (int j = 0; j < group.get(x).getalunos().size(); j++) {
if(filhos.get(x).get(j).isChecked()){
v.getChildAt(j).findViewById(R.id.loadingPanel).findViewById(R.id.overlay).setVisibility(View.GONE);
}
nomeAluno.setTextColor(color);
}
}
}
}
佈局：
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@drawable/nomealuno_main"
android:layout_below="@+id/child">
<View
android:id="@+id/overlay"
android:layout_width="125dp"
android:layout_height="50dp"
android:background="@color/bgOverlay"
android:visibility="gone"/>
</RelativeLayout>
這裏是什麼是happenin G：
當我選擇從A所有的項目給B這樣的：
：
和命中清楚，它只會從我點擊了最後一組中刪除選定的孩子
我需要將它們全部刪除，當我點擊清除時，所有的孩子，不管他們在什麼組中都必須被刪除。
