如何使ListView条目居中对齐？(Android)

// 自定义Adapter类
public class MyAdapter extends BaseAdapter {
    private List<String> data;
    private Context context;

    public MyAdapter(Context context, List<String> data) {
        this.context = context;
        this.data = data;
    }

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

    @Override
    public Object getItem(int position) {
        return data.get(position);
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.textView = convertView.findViewById(R.id.text_view);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.textView.setText(data.get(position));

        return convertView;
    }

    static class ViewHolder {
        TextView textView;
    }
}

// 在Activity或Fragment中使用ListView
public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private MyAdapter adapter;
    private List<String> data;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView = findViewById(R.id.list_view);
        data = new ArrayList<>();
        // 添加数据
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");

        adapter = new MyAdapter(this, data);
        listView.setAdapter(adapter);

        // 将第二个条目居中显示
        listView.setSelection(1);
    }
}
