Hi all I want to update a row on clicking on update button,but its doesn't work. I have used following code.

 public void btnUpdate(View v) { 
handeler.updateData(updateName.getText().toString(), updatePhone .getText().toString(), updateEmail.getText().toString(),id);
 } 

public void updateData(String name, String phone, String email, String id) {
 ContentValues values = new ContentValues(); 
values.put(COLUMN_FIRST, name); 
values.put(COLUMN_SECOND, phone); values.put(COLUMN_THIRD, email); database.update(TABLE_NAME, values, id, null); 
} 
public void search() {
        Cursor cursor = handeler.getData();
        if (cursor.moveToFirst()) {
            String phoneNo;
            phoneNo = updateByPhone.getText().toString();
            do {
                String s1 = cursor.getString(2);
                if (phoneNo.compareTo(s1) == 0) {
                    id = cursor.getString(0);
                    updateName.setText(cursor.getString(1));
                    updateEmail.setText(cursor.getString(3));
                    updatePhone.setText(cursor.getString(2));

                }
            } while (cursor.moveToNext());

        }

    }

So if any know please suggest me how to solve it. Thanks
