如何在Listview中设置textview的背景色

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:textColor="#FFFFFF"
    android:textSize="16sp" />

public class MyAdapter extends BaseAdapter {
    private Context context;
    private List<String> dataList;

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

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

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

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = convertView;
        if (view == null) {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = inflater.inflate(R.layout.list_item, null);
        }

        TextView textView = view.findViewById(R.id.textView);
        textView.setText(dataList.get(position));

        // 设置背景色
        if (position % 2 == 0) {
            textView.setBackgroundColor(Color.BLUE);
        } else {
            textView.setBackgroundColor(Color.GREEN);
        }

        return view;
    }
}

public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private List<String> dataList;

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

        listView = findViewById(R.id.listView);
        dataList = new ArrayList<>();
        dataList.add("Item 1");
        dataList.add("Item 2");
        dataList.add("Item 3");
        dataList.add("Item 4");
        dataList.add("Item 5");

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