        openDatabase();
        db.beginTransaction();
        try {
            ContentValues values = new ContentValues();

            db.setTransactionSuccessful();
            closeDatabase();
            if (result == -1)
                return false;
            else
                return true;
        } catch (Exception e) {
            e.printStackTrace();
            Log.d(TAG, "???? ??? ?? ???????");

        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                try {
                    boolean isInserted = DB_HELPER.insertUser(EDT_NAME.getText().toString(), Integer.parseInt(EDT_AGE.getText().toString()),
                            Integer.parseInt(EDT_GENDER.getText().toString()), Integer.parseInt(EDT_PASS.getText().toString()),
                            EDT_DESC.getText().toString(), EDT_PIC.getText().toString());
                    if (isInserted == true)
                        startActivity(new Intent(AddActivity.this, MainActivity.class));
                    else
                        Snackbar.make(view, "??? ?? ??? ????? ????!", Snackbar.LENGTH_LONG).setAction("Action", null).show();
                } catch(Exception e){
                    e.printStackTrace();
                    return;
                }
            }
        });

    private int id;
    private String userName;
    private int age;
    private int gender;
    private int password;
    private String memDescription;
    private String pic;

    public User(int id, String userName, int age, int gender, int password, String memDescription, String pic) {
        this.id = id;
        this.userName = userName;
        this.age = age;
        this.gender = gender;
        this.password = password;
        this.memDescription = memDescription;
        this.pic = pic;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getGender() {
        return gender;
    }

    public void setGender(int gender) {
        this.gender = gender;
    }

    public int getPassword() {
        return password;
    }

    public void setPassword(int password) {
        this.password = password;
    }

    public String getMemDescription() {
