You can go for base adapter for this type of requirement wherein you can have the facility to modify a lot of things. To know and implement base adapter go through the links :

How to customize listview using baseadapter

http://abhiandroid.com/ui/baseadapter-tutorial-example.html

You can easily customize the base adapter for your required data and font.

Create a base adapter as below : 


public class CustomAdapter extends BaseAdapter {
    Context context;
    ArrayList<String> arrayList;
    LayoutInflater inflter;
    Typeface font;

    public CustomAdapter(Context applicationContext,  ArrayList<String> arrayList) {
        this.context = applicationContext;
        this.arrayList = arrayList;
        inflter = (LayoutInflater.from(applicationContext));
        font = Typeface.createFromAsset(context.getAssets(), "fonts/Questrial-Regular.ttf");
    }

    @Override
    public int getCount() {
        return arrayList.size();
    }

    @Override
    public Object getItem(int i) {
        return null;
    }

    @Override
    public long getItemId(int i) {
        return 0;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        view = inflter.inflate(R.layout.activity_item, null);
        TextView tv = (TextView) view.findViewById(R.id.tv);
        tv.setText(arrayList.get(i));
        tv.setTypeface(font);
        return view;
    }
}

Main activity

public class MainActivity extends AppCompatActivity {
    ArrayList<String> simpleStringArrayList;
    ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        simpleStringArrayList = new ArrayList<>();
        simpleStringArrayList.add("aaa");
        simpleStringArrayList.add("bbb");
        simpleStringArrayList.add("ccc");
        simpleStringArrayList.add("ddd");
        simpleStringArrayList.add("eee");
        simpleStringArrayList.add("fff");
        simpleStringArrayList.add("ggg");

        listView = (ListView) findViewById(R.id.listView);
        listView= (ListView) findViewById(R.id.listView);
        CustomAdapter customAdapter = new CustomAdapter(this, simpleStringArrayList);
        listView.setAdapter(customAdapter);
    }
}
