Want to get title and date of checked CheckBox from ExpandableListView when Click on submit Button

Question

I created ExpandableListView with titles and checkBox as GroupItem and Due Date and date as child Item..

I want to get Only _title_(Monthly Return Filing in Form 10) and _date_(15th of Next Month) of checked checkBoxes when user select them and click on submit button

My BaseExpandableListAdapter

@Override
public View getGroupView(final int groupPosition, boolean isExpanded,
                         View convertView, ViewGroup parent) {
    Group_Items gr = (Group_Items) getGroup(groupPosition);
    long group_id = getGroupId(groupPosition);

    if (convertView == null) {
        LayoutInflater inf = (LayoutInflater) context
                .getSystemService(context.LAYOUT_INFLATER_SERVICE);
        convertView = inf.inflate(R.layout.expandable_group_items, null);

        // adding onClick listener on CheckBox for the very first time
        chk = (CheckBox) convertView.findViewById(R.id.chk);
        chk.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                int position = (int) v.getTag();
                mSelections.put(position, !mSelections.get(position, false));
                ((CheckBox) v).setChecked(mSelections.get(position, false));
            }
        });
    }

    final TextView title = (TextView) convertView.findViewById(R.id.title);
    title.setText(gr.getName());
    CheckBox chk = (CheckBox) convertView.findViewById(R.id.chk);
    chk.setTag(groupPosition);

    // reassigning checkbox to its ticked state
    chk.setChecked(mSelections.get(groupPosition, false));
    });
    if (groupPosition==7){
        chk.setVisibility(View.GONE);
        return convertView;
    }else {
        chk.setVisibility(View.VISIBLE);
        return convertView;
    }
}

I took submit_info button in my FirstRow.java and want to get values of selected CheckBox when click on submit button with onClickListener So, guys how to get values of the same please help me..

can you post your constructor? and what is `gru.setItems(ch_list);` — Iamat8, Feb 14 '16 at 06:41
@Mohit here is my constructor... `public MyBaseExpandableListAdapterFirstRow(Context context, ArrayList group_al) { this.context=context; this.group_al=group_al; }` — kalmeshwar gurav, Feb 14 '16 at 06:43
@Mohit `gru` is a object of `Group_Items` class which contains `getter` and `setter` method and `setItems` is one of the setter method from that `Group_Items` class So, gru `setItems` on list.. — kalmeshwar gurav, Feb 14 '16 at 07:04

Seems the mSelections in your adapter already keeps checked positions with some data, but it only adds data to it when check box is checked but doesn't remove the data from it when unchecked.

You have a View.OnClickListener set on the check box, you can get the checked status from ((CheckBox) v).isChecked(). Then update the mSelections accordingly.

Now you can make a public method on the adapter to get a list of selected Group_Items via the mSelection which contains all the checked positions, the same as the indices of the underlying data list.

View.OnClickListener is not ideal. Because check box has its own OnCheckedChangeListener, you don't have to cast the view to a check box to get check status.

I am little bit confused can you give me some code to explain it — kalmeshwar gurav, Feb 14 '16 at 06:26

Get your group name by String in array list at groupPosition you are passing to constructor and you child date by getting getDate() at childPosition of getItems at groupPosition...

On your submit button call like...

String name = group_al.get(groupPosition).getName();
String date = group_al.get(groupPosition).getItems().get(childPosition).getDate();

this will return name and date of check box clicked – Iamat8 Feb 14 '16 at 07:18
Where I put my button? in my FirstRow.java or in BaseExpandableListAdapter.java?? – kalmeshwar gurav Feb 14 '16 at 07:23
in your `getGroupView` – Iamat8 Feb 14 '16 at 07:23
where you are using button? – Iamat8 Feb 14 '16 at 07:24
in `FirstRow.java` not in the `CustomAdapter` – kalmeshwar gurav Feb 14 '16 at 07:25
ok make a global arraylist [from here](http://stackoverflow.com/a/35183420/2553431) where you can store your all check value...and use it on submit button.. – Iamat8 Feb 14 '16 at 07:29
insted of that now I am put my code in `custom Adapter` but it shows error at `String date = group_al.get(groupPosition).getItems().get(childPosition).getDate();` as can not resolve symbol childPosition – kalmeshwar gurav Feb 14 '16 at 07:35
I will try sir wait a second – kalmeshwar gurav Feb 14 '16 at 07:46

`groupPosition` is first parameter in your `getChildView` method – Iamat8 Feb 14 '16 at 07:51

does `submit_info` button belongs to `expandable_child_items` layout – Iamat8 Feb 14 '16 at 09:39
no it is on `expandable_listview.xml` below the `expandableListView` – kalmeshwar gurav Feb 14 '16 at 09:41
you can not call button if it do not belong to `expandable_child_items` – Iamat8 Feb 14 '16 at 09:44
sir, How I get that selected values now – kalmeshwar gurav Feb 14 '16 at 09:55
any solution for that sir – kalmeshwar gurav Feb 14 '16 at 09:56
i think you should use check box at child not at group ,because if you are put there you have to get all child text value not single one... – Iamat8 Feb 14 '16 at 09:57
but sir client wants it at GroupPosition – kalmeshwar gurav Feb 14 '16 at 09:59
It is possible to get all selected values in FirstRow. java file – kalmeshwar gurav Feb 14 '16 at 10:00
no sir only selected child date and group title only – kalmeshwar gurav Feb 14 '16 at 10:02
how will you select child date if you do not have check box there..? – Iamat8 Feb 14 '16 at 10:04
I think in `getGroupView` by using `onClickListener` on `CheckBox` I can access them.. Is it possible? – kalmeshwar gurav Feb 14 '16 at 10:10
how it will know child click on which position ? – Iamat8 Feb 14 '16 at 10:11
as you can not get child position there – Iamat8 Feb 14 '16 at 10:12
what i will do sir. I am so confused now tomorrow is a Deployment date – kalmeshwar gurav Feb 14 '16 at 10:13
you have put check box in child, so when you click it you gets its position....else only option is to get all text of child – Iamat8 Feb 14 '16 at 10:15
ok Sir.. Can I get two `checkboxes` one at `group position` and another at `child` next to date... and when click on `group position` `check box` then `child position` `checkbox` will be checked. – kalmeshwar gurav Feb 14 '16 at 10:24
I will add another `CheckBox` next to `child` item but how it is possible to when user Check `checkbox` of Group item then `CheckBox` of child item also get Checked? There is any Logic for that – kalmeshwar gurav Feb 14 '16 at 10:32
check if current group position check box is check and if it is ,then setcheck to all of check box inside child – Iamat8 Feb 14 '16 at 10:37
take a boolean variable, at `chk.setOnClickListener(new View.OnClickListener())` true this boolean, and on your `getChildView` check all checkbox if this boolean is true else uncheck all... – Iamat8 Feb 14 '16 at 11:01
