我有一個customListView與複選框和textview和我woul喜歡總結被檢查的值，並顯示它在textview上。customListView的複選框和textview，如何總結textview的值檢查？
這是我的代碼：
row2.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?android:attr/activatedBackgroundIndicator"
android:descendantFocusability="blocksDescendants"
android:padding="1dp" >

android:layout_alignParentStart="true"
android:layout_alignParentBottom="true">
</CheckBox>
<TextView
android:id="@+id/tv_qta1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/tv_grm"
android:gravity="center_vertical|right"
android:paddingRight="5dp"
android:text="@string/v10000"
android:textColor="@android:color/holo_red_dark"

的int actyvity我創建listviecustom
if(userAdapterRct1 == null){
userAdapterRct1 = new ItemsListAdapterRct(getActivity().getBaseContext(), userArrayRct1);
userListRct1 = (ListView) rootView.findViewById(R.id.ListView01);
userListRct1.setItemsCanFocus(true);
userAdapterRct1.notifyDataSetChanged();
userListRct1.setAdapter(userAdapterRct1);
userAdapterRct1.notifyDataSetChanged();
}else
userAdapterRct1.notifyDataSetChanged();
if(userAdapterRct1 != null){
userListRct1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View v,int position, long id) {
// TODO Auto-generated method stub
RelativeLayout listItem = (RelativeLayout) v;
TextView clickedItemView = (TextView) listItem.findViewById(R.id.tv_prodotto);
CheckBox cbView = (CheckBox) listItem.findViewById(R.id.cbBox);
cbView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
//@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
//Integer rct = (Integer) buttonView.getTag();
// create the suf of items checked
}
});
}
});
}
如何創建項目的總和檢查？
ItemsListAdapterRct.java
class ItemsListAdapterRct extends BaseAdapter {
private LayoutInflater vi;
private ArrayList<User> data = new ArrayList<User>();
Context context;
public ItemsListAdapterRct(Context context, /*int layoutResourceId,*/ ArrayList<User> data) {
vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.data = data;
this.context = context;
}
/** Add white line */
public void addItem(User item) {
data.add(item);
notifyDataSetChanged();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
User p = getProduct(position);
if (convertView == null) {
holder = new ViewHolder();
convertView = vi.inflate(R.layout.row2, parent, false);//null);
holder.name = (TextView) convertView.findViewById(R.id.tv_prodotto);
holder.qty_ing = (TextView) convertView.findViewById(R.id.tv_qta1);
holder.qty_risc = (TextView) convertView.findViewById(R.id.tv_qta2);
holder.cbView = (CheckBox) convertView.findViewById(R.id.cbBox);
convertView.setTag(holder);
}else {
holder = (ViewHolder) convertView.getTag();
}
if(holder.name != null) {
holder.name.setText(data.get(position).getName());
}
if(holder.qty_ing != null) {
holder.qty_ing.setText(String.valueOf(data.get(position).getQtyIng()));
}
if(holder.qty_risc != null) {
holder.qty_risc.setText(String.valueOf(data.get(position).getQtyRis()));
}
if(holder.cbView != null) {
holder.cbView.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
//@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
getProduct((Integer) buttonView.getTag()).box = isChecked;
//
// // aggiorno il db
// DatabaseHelper dbRcp = new DatabaseHelper(context, ImportFragment.DB_DATABASE_STORE);
// int pos = (Integer) buttonView.getTag();
// Ricetta p = getProduct(pos);
// String box = "0";
// if(p.box) box = "1";
// long res = dbRcp.update_Riscala(p.id, p.name, "0", box);
// // Don't forget to close database connection
// dbRcp.closeDB();
}
});
//cbBuy.setOnCheckedChangeListener(myCheckChangList);
holder.cbView.setTag(position);
holder.cbView.setChecked(p.box);
}
return convertView;
}
User getProduct(int position) {
return ((User) getItem(position));
}
// /** Sort shopping list by name ascending */

}
@Override

}
@Override

}
/** Helper class acting as a holder of the information for each row */
private class ViewHolder {

}
}
我想總結紅色簽署的價值，並把結果在底部的TextView
是的，完美！ thaks –
