Perform sqlite query and nothing happens

Strange one here. I have a database with a fixtures table which holds all the fixtures for a sports teams season. I am trying to create the functionality to allow the manager of the team to edit a fixture. I am able to select all the fixtures and return them to the listview but when I try to perform a query based upon the match_date column, nothing happens.

public class EditSchedule extends AppCompatActivity {

    public Button fixtureSearch;
    public EditText fixtureDate;
    public String searchDate;

    ListView editMatch;

    DBHelper dbHelper = new DBHelper(this);

    SQLiteDatabase sqLiteDatabase;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_editfixture);

        editMatch = (ListView) findViewById(R.id.listViewEditMatch);
        fixtureDate = (EditText) findViewById(R.id.fixtureDateEditSearch);
        searchDate = fixtureDate.getText().toString();

        fixtureSearch = (Button) findViewById(R.id.fixtureSearchButton);
        fixtureSearch.setOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        //populate listview with query result

                        //final Cursor cursor = dbHelper.getAllFixtures();
                        final Cursor cursor = dbHelper.getMatch(searchDate);

                        final FixtureAdapter fixtureAdapter = new FixtureAdapter(getApplicationContext(), cursor, 0);

                        editMatch.setAdapter(fixtureAdapter);

                    }
                    }
        );
    }

}

My getMatch method in DBHelper looks like this:

    public Cursor getMatch(String date) {
        SQLiteDatabase sqLiteDatabase = getWritableDatabase();

        String[] match = {_ID, MATCH_DATE, MATCH_OPPONENT, MATCH_VENUE, MATCH_TIME};

        return sqLiteDatabase.query(TABLE_FIXTURES, match, MATCH_DATE + " = '" + date + "'", null, null, null, null);
    }
}

There is nothing at all in the logcat when I click the search button, and you can see EditSchedule class that I have commented out the getAllFixtures cursor which does work. Your help would be greatly appreciated.
