Android: Update data by its Id

I've been trying to update the data on sqlite database, but before the data will update the users will search for the Id of the data and will load to the Edittext. I have no error in my Logcat but when I click the update button it will only show the toast message and when I check the data, there is no changes. Please I need help..Please check my codes. Thank you..

My DatabaseHelper class:

  public void updateData(int id, String new_question, String new_ans1, String new_ans2, String new_ans3, String new_ans4, SQLiteDatabase sqLiteDatabase )
    {
        ContentValues contentValues = new ContentValues();

        contentValues.put(AdminContact.Question.COLUMN_QUESTION, new_question);
        contentValues.put(AdminContact.Question.COLUMN_ANSWER1, new_ans1);
        contentValues.put(AdminContact.Question.COLUMN_ANSWER2, new_ans2);
        contentValues.put(AdminContact.Question.COLUMN_ANSWER3, new_ans3);
        contentValues.put(AdminContact.Question.COLUMN_ANSWER4, new_ans4);


        sqLiteDatabase.update(AdminContact.Question.TABLE_QUIZ, contentValues, AdminContact.Question.ID +"="+id, null);

My Update class:

    EditText Search_Id, New_Question, New_Ans1, New_Ans2, New_Ans3, New_Ans4;
    DatabaseHelper helper;
    String SearchID, NewId, NewQuestion, NewAns1, NewAns2, NewAns3, NewAns4;
    SQLiteDatabase sqLiteDatabase;
    TextView title_text;
    Button updateButton;
    int id;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_update_contact);
        helper = new DatabaseHelper(this);

        Search_Id = (EditText) findViewById(R.id.id_search);

        updateButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v.getId() == R.id.update_button) ;

                sqLiteDatabase = helper.getWritableDatabase();
                String question, ans1, ans2, ans3, ans4;

                question = New_Question.getText().toString();

                Toast.makeText(getApplicationContext(),"Successfully Updated", Toast.LENGTH_LONG).show();
            }
        });

    }

    public void searchContact(View view) {

        SearchID = Search_Id.getText().toString();
        sqLiteDatabase = helper.getReadableDatabase();
        Cursor cursor = helper.getData(SearchID, sqLiteDatabase);
        if (cursor.moveToFirst()) {

            NewAns3 = cursor.getString(3);
            NewAns4 = cursor.getString(4);
            NewId = SearchID;

            New_Question.setText(NewQuestion);
