i think your using a custom adapter for ListView, then use the Button OnClick in Adapter getView()..

 holder.yourbutton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
                Intent in = new Intent(context, AboutUs.class);
                context.startActivity(in);
            }
         }

You have to use the Custom Adapter.

Create a class and extends with BaseAdapter
In getView Methods you must add the Click event of that button and specific action on that button
Set the Listview this adapter in main Activity.

Your problem is in the onItemClick method. You can read this to understand the parameters from this method.

You need to check the position differently:

 @Override
 public void onItemClick(AdapterView<?> arg0, View arg1,
          int position, long arg3) {

         switch (position) {
         case 0: // For "Arun Arora Chairman, Edvance Group"
             Intent in = new Intent(getApplicationContext(), AboutUs.class);
             startActivity(in);
             break;
         case 1: // For "Anshul Arora CEO, Edvance Group "
             Intent in = new Intent(getApplicationContext(), AboutUs.class);
             startActivity(in);
             break;
         ...
         }
}

If you want to launch the same Activity, you can remove the switch case.

This method will trigger the onItemClick even if the click is outside the button, if you want to restrict it to the button you need to create a CustomAdapter.

hi giant00 if i click the readmore button i want to move to next activity this is my question — user1, Jul 30 '14 at 08:03
You need to follow the link in my answer and do a `CustomAdapter`. You will also find how to do it [here](http://stackoverflow.com/questions/8166497/custom-adapter-for-list-view). — calimbak, Jul 30 '14 at 08:13

add the following code below this line click = (Button)findViewById(R.id.click); in your code .

click.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent in = new Intent(OurTeam.this, AboutUs.class);
            startActivity(in);

        }
    });
