Actually I've implemented listview where we can select appropriate row by tapping on togglebutton associated with it. I'm adding data which is on that row to arraylist. But, where I'm facing problem is that when i select e.g. row1 and then row2 the data which is in arraylist is like this: (row1 data,row1 data,row2 data), here row1 data is repeating.. But, I need this: (row1 data,row2 data). Even I'm trying to use clear() method also. But, when i used it, it is rither showing blank data or data last selected..
So, What I should do?
Please , help me.
