How to manipulate data in list view that is populated by custom cursor adapter

I have populated a list view using the custom cursor adapter, That listview consists of a checkbox and button in the below manner.

checkbox1 button1
checkbox2 button2
.
.
.

Now I want to navigate to another activity when click on the button in list view now my issue here is when I click on the button1 then I want to see the data in checkbox1 and similarly for other rows as well.

Now I am confused on how to maintain a sync between the checkbox and button and how to achieve the click functionality. How can I achieve this?

Check this post might help. You have to preserve the state of row in listview so row can be populated with its state.

Use a ViewHolder class in adapter class and use that in getView(), Then within getView

viewHolder.yourButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(viewHolder.checkbox.isChecked())
                                // toggle the check and do your work here
        }
    });

You can learn ViewHolder pattern here its very simple

You will need to find your corresponding view in the list view implementing the onclickListener

For eg

    listView.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

            Button b = (Button)v.findViewById(R.id.button);
                            b.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                                  Intent i=new Intent(this,SecondActivity.Class)
                                   startActivity(i);    
                           }
            });
                            //Similarly for the checkbox
        }
    });

You can do the following on the Button's onClickListener if the Button and CheckBox share the same parent

boldButton.setOnClickListener(new OnClickListener()
{

    @Override
    public void onClick(View view)
    {
       View parentView = (View) view.getParent();
       CheckBox checkBox = (CheckBox) parentView.findViewById(R.id.check);
    }
});

This will give you the CheckBox corresponding to the clicked Button
