如何在React Navigation5中动态设置导航栏标题和背景颜色

import { useNavigation } from '@react-navigation/native';

function MyScreen() {
  const navigation = useNavigation();

  // 动态设置导航栏标题
  useEffect(() => {
    navigation.setOptions({
      title: '动态标题',
    });
  }, []);

  // 渲染你的组件
  return (
    // ...
  );
}

import { useNavigation, useFocusEffect } from '@react-navigation/native';

function MyScreen() {
  const navigation = useNavigation();

  // 动态设置导航栏背景颜色
  useFocusEffect(() => {
    navigation.setOptions({
      headerStyle: {
        backgroundColor: 'red',
      },
    });
  });

  // 渲染你的组件
  return (
    // ...
  );
}
