Question

how can we back to the first activity from a adapter button click

holder.close.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub
                        onBackPressed(); 
                    }
                }) ;
            return convertView;
        }   

Answer 1

if your previous activity is on stack just call -

((Activity) mContext).finish();

else call previous activity using intent & finish current activity.

holder.close.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Intent mIntent=new Intent(mContext,MyActivity.class);
                    mContext.startActivity(mIntent);
                    ((Activity) mContext).finish();
                }
            }) ;
        return convertView;
    }   

Answer 2

You can write code in Activity's onBackPressed() method for going to previous activity,and then give call to activity's onBackPressed() method from adapter.

((Your Activity)context).onBackPressed();
