Как кастомизировать ListView?

Добрый день!
Столкнулся с небольшой проблемой. Не могу никак изменить listview. Нужно сделать текст больше, а то он слишком мелкий.
Вот мой MainActivity:

import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ContextMenu.ContextMenuInfo;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.AdapterView.AdapterContextMenuInfo;

public class MainActivity extends ListActivity {
    private static final int ACTIVITY_CREATE=0;
    private static final int ACTIVITY_EDIT=1;

    private static final int INSERT_ID = Menu.FIRST;
    private static final int DELETE_ID = Menu.FIRST + 1;

    private NotesDbAdapter mDbHelper;
    private Cursor mNotesCursor;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mDbHelper = new NotesDbAdapter(this);
        mDbHelper.open();
        fillData();
        registerForContextMenu(getListView());
    }

    public void onBackPressed() {
        moveTaskToBack(true);

        this.finish();
        return;
    }
    private void fillData() {
        // Get all of the rows from the database and create the item list
        mNotesCursor = mDbHelper.fetchAllNotes();
        startManagingCursor(mNotesCursor);
        // Create an array to specify the fields we want to display in the list (only TITLE)
        String[] from = new String[]{NotesDbAdapter.KEY_TITLE};
        // and an array of the fields we want to bind those fields to (in this case just text1)
        int[] to = new int[]{R.id.text1};
        // Now create a simple cursor adapter and set it to display
        SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.notes_row, mNotesCursor, from, to);
        setListAdapter(notes);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        menu.add(0, INSERT_ID, 0, "New Note");
        return true;
    }

    @Override
    public boolean onMenuItemSelected(int featureId, MenuItem item) {
        switch(item.getItemId()) {
            case INSERT_ID:
                createNote();
                return true;
        }
        return super.onMenuItemSelected(featureId, item);
    }

    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
        super.onCreateContextMenu(menu, v, menuInfo);
        menu.add(0, DELETE_ID, 0, "Delete");
    }

    @Override
    public boolean onContextItemSelected(MenuItem item) {
        switch(item.getItemId()) {
            case DELETE_ID:
                AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
                mDbHelper.deleteNote(info.id);
                fillData();
                return true;
        }
        return super.onContextItemSelected(item);
    }

    private void createNote() {
        Intent i = new Intent(this, NewText.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Cursor c = mNotesCursor;
        c.moveToPosition(position);
        Intent i = new Intent(this, NewText.class);
        i.putExtra(NotesDbAdapter.KEY_ROWID, id);
        i.putExtra(NotesDbAdapter.KEY_TITLE, c.getString(c.getColumnIndexOrThrow(NotesDbAdapter.KEY_TITLE)));
        i.putExtra(NotesDbAdapter.KEY_BODY, c.getString(c.getColumnIndexOrThrow(NotesDbAdapter.KEY_BODY)));
        startActivityForResult(i, ACTIVITY_EDIT);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        Bundle extras =intent.getExtras();
        switch(requestCode) {
            case ACTIVITY_CREATE:
                String title = extras.getString(NotesDbAdapter.KEY_TITLE);
                String body = extras.getString(NotesDbAdapter.KEY_BODY);
                mDbHelper.createNote(title, body);
                fillData();
                break;
            case ACTIVITY_EDIT:
                Long rowId = extras.getLong(NotesDbAdapter.KEY_ROWID);
                if (rowId != null) {
                    String editTitle = extras.getString(NotesDbAdapter.KEY_TITLE);
                    String editBody = extras.getString(NotesDbAdapter.KEY_BODY);
                    mDbHelper.updateNote(rowId, editTitle, editBody);
                }
                fillData();
                break;
        }
    }
}

activity_main:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    style="@style/Widget.AppCompat.TextView.SpinnerItem">
    <ListView android:id="@+id/android:list" android:layout_width="wrap_content" android:layout_height="wrap_content"
        style="@style/Widget.AppCompat.TextView.SpinnerItem"
        />
    <TextView android:id="@+id/android:empty" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="No New Notes…Press on Menu to Add New Note"
        android:textSize="24sp"
        android:password="false" />
</LinearLayout>

Заранее спасибо!
