                    sqldb.insert("urdet", null,cv);
                    cv.clear();
                    Toast.makeText(getApplicationContext(), "inserted", Toast.LENGTH_SHORT).show();
                    }
                    dba.close();
                    Intent i = new Intent(Yourwill.this, Section.class);
                    startActivity(i);
                    finish();

                else
                {
                    Willdto.setposition(Integer.parseInt(aId.get(position)));
                    Intent i = new Intent(Yourwill.this, Section.class);
                    startActivity(i);
                    finish();
                }

            deletbtn.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    SQLiteDatabase sqldb = dba.openDataBase();
                    String[] arr = { "" + aId.get(position) };
                    sqldb.delete("urdet", "Id = ?", arr);
                    Toast.makeText(getApplicationContext(), "Delete", Toast.LENGTH_SHORT).show();
                    Log.v("log_tag", "pos   " + aId.get(position));
                    dba.close();
                    Intent i = new Intent(Yourwill.this,Yourwill.class);
                    startActivity(i);
                    finish();
                }
            });
            bt.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    deletbtn.setVisibility(View.VISIBLE);
                }
            });

        return convertView;
    }

The way to do this would be to

1. Have those buttons created with attribute android:visibility="gone"
2. Inside the onClick handler for top button change the visibility using setVisibility(View.VISIBLE)
