Question

My ListView contains Ten Rows. Each rows contained the CheckBox. How would I check and uncheck the CheckBox using setOnItemClickListener

Sample Code : (it’s not working for me)

listview.setOnItemClickListener( new OnItemClickListener() 
{
    public void onItemClick( AdapterView<?> parent, final View v, final int position, long id ) 
    {
        Toast.makeText( this, " Position is " + position, Toast.LENGTH_SHORT ) .show();
        holder.checkbox = ( CheckBox ) v.findViewById( R.id.lock_File_CheckBox );
        holder.checkbox.toggle();
    }
});

How do we find whether CheckBox is checked or unchecked?

Answer 1

To get the instance of Checkbox inside onItemClick() you need to use setTag() and getTag() for checkbox instance. You can check my example on my blog that shows how we can get the instance of CheckBox inside onItemClick().

After getting your CheckBox instance inside onItemClick() update your content of list and notify your adapter inside onItemClick() as,

if(checkbox.isChecked())
    list.get(position).setSelected(false);
else
    list.get(position).setSelected(true);

adapter.notifyDataSetChanged();
