Question

I am using ListView with CheckBox. I have selected only one CheckBox but it’s automatically selected into Multiple Rows using ScrollView.

Sample Code (This Code is working Perfectly)

       holder.checkbox.setOnClickListener( new OnClickListener()
        {
            public void onClick( View v )
            {
                CheckBox cb = ( CheckBox ) v;
                if ( cb.isChecked() )
                {
                    test[position] = true;
                    holder.checkbox.setChecked(test[position]);
                }
                else
                {
                    test[position] = false;
                    holder.checkbox.setChecked(test[position]);
                }
            }
        });
        holder.checkbox.setChecked(test[position]);

But When i uses setOnItemClickListener it’s not working.

Sample Code (This code is not working for me)

        listview.setOnItemClickListener( new OnItemClickListener() 
        {
            public void onItemClick( AdapterView<?> parent, final View v, final int position, long id ) 
            {
                holder.checkbox = ( CheckBox ) v.findViewById( R.id.lock_File_CheckBox );
                if ( holder.checkbox.isChecked() )
                {
                    test[position] = false;
                    holder.checkbox.setChecked(test[position]);
                }
                else
                {
                    test[position] = true;
                    holder.checkbox.setChecked(test[position]);
                }
            }
        });
        holder.checkbox.setChecked(test[position]);

Where i can mistaken. How do avoid this CheckBox Selection.

Can you please help me?

Answer 1

You can get the instance of CheckBox inside onItemClick() by using setTag() and getTag(). You can setTag the CheckBox instance inside your getView() method as

convertView.setTag(R.id.check, viewHolder.checkbox);

And get the instance inside onItemClick() using,

CheckBox checkbox = (CheckBox) v.getTag(R.id.check);
