You could always send a onClickListener from your Activity to your adapter when you create it.

Otherwise set a listener in your adapter or by using the onClick in the xml of the item.

When I did similar things I passed my activities onclicklistener to my adapter.

Edit: Examples:

Or better:

Android: ListView elements with multiple clickable buttons

It all depends on how you will do it. But the other answer will probably work, just pass the correct context.

it is very simple set holder.butAddNew.setOnClickListener in getView like as

holder.butAddNew.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Intent code for Start Activity
            }
        });

create constructor of your customeadapter class and pass activity or context in that constructor and use that for start activity.

updated

public View getView(int position, View convertView, ViewGroup parent) 

{
    ViewHolder holder;

if(convertView==null)
{
    holder = new ViewHolder();
    convertView = inflater.inflate(R.layout.histryfrm_listview, null);
    holder.butAddNew =(Button) convertView.findViewById(R.id.butAddNew);
    holder.txtViewTitle =(TextView) convertView.findViewById(R.id.txtViewTitle);
    holder.txtViewDescription =(TextView) convertView.findViewById(R.id.txtViewDescription);
    holder.txtViewHeading =(TextView) convertView.findViewById(R.id.txtViewHeading);

    convertView.setTag(holder);
}
else
    holder=(ViewHolder)convertView.getTag();

holder.txtViewTitle.setText(title[position]);
holder.txtViewDescription.setText(description[position]);
holder.txtViewHeading.setText(heading[position]);
holder.butAddNew.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(Context, activity.class));
            }
        });

return convertView;
}

But inside how i can call another activity..thats what i want. — AndroidDev, Jul 06 '11 at 12:21
i have updated it in my code but it show error in startActivity..i have just send you the updated code.. — AndroidDev, Jul 06 '11 at 12:48
first check did you add your new activity in menifest and second thing is pass proper context in intent like as getBaseContext() or getApplicationContext(); — Niranj Patel, Jul 06 '11 at 12:51
