Finding The Checked State Of Checkbox In A Custom Listview

Hai i'm trying to develop an app where by i can send sms and email to a particular group of people.. I have a listview showing the contacts which are in my group.Each row is of the

Solution 1:

Inside the getView() method, you have to implement a OnCheckedChangeListener for the CheckBox.

Here is a listener code, say for example:

ChkBx.setOnCheckedChangeListener(newOnCheckedChangeListener()
{
    publicvoidonCheckedChanged(CompoundButton buttonView, boolean isChecked)
    {
        if ( isChecked )
        {
            // perform logic
        }

    }
});

Solution 2:

See the doc.

I think you need :

checkbox.isChecked()

Solution 3:

Here's a simple sample:

mContactListView.setOnItemClickListener(newOnItemClickListener() {

        @OverridepublicvoidonItemClick(AdapterView<?> parent, View view, int position, long arg3) {

            CheckBoxchkContact= (CheckBox) view.findViewById(R.id.listrow_contact_chkContact);
            if (chkContact.isChecked()) {
                ...
            }
});

I've had this problem with my app Hasta La Vista I've create a with custom listview with checked items and I needed to get checked items this was the solution:

ListViewlv= getListView(); //ver listviewif(lv != null){
        finalSparseBooleanArraycheckedItems= lv.getCheckedItemPositions(); //get checked itemsif (checkedItems == null) {
            return;
        }

        finalintcheckedItemsCount= checkedItems.size();
        for (inti=0; i < checkedItemsCount; ++i) {
            // This tells us the item position we are looking atfinalintposition= checkedItems.keyAt(i);
            // This tells us the item status at the above positionfinalbooleanisChecked= checkedItems.valueAt(i);

            if(isChecked){
                                    //get item from list and do something
                lv.getAdapter().getItem(position);

            }
        }

    }

Solution 5:

As ListView views are recycled, you can not rely on listening on particular instance, you will have to store "checked" state in your data model. You will also need custom list adapter, where you create and populate individual entries. Following shall be done: - in overriden getView(), either create new view ( in case no convertView was supplied ) or inflate new one - populate viewv fields from you data model - remove old onclick listener, and set new one ( can be anonymous inner class ) modifying your data model

PS: recycling views is important if your list is big
