從react-native屏幕上刪除導航標題-代碼日志

Question

我有一個帶有選項卡式導航的屏幕，其中每個屏幕都是堆棧導航類型，每個屏幕中定義了幾個屏幕。 當我從FamilyMembers導航到SingleContact屏幕時，我不想看到頂部帶有后退按鈕的導航欄。 我希望單一聯系人的觀點（藍色觀點）從頂部開始。 但是，盡管我將標頭設置為null，但它似乎仍然存在！ 請幫忙。

您是否已經像這樣在HomeScreenStack中修改了FamilyMembersStack？

    const HomeScreenStack = createStackNavigator({
  Home: {
    screen: HomeScreen,
    navigationOptions: ({ navigation }) => {
      return {
        header: null,
      }
    },
  },

  // modify this Stack

  FamilyMembersStack:{
    screen: FamilyMembersStack,
    navigationOptions: ({ navigation }) => {
      return {
        header: null
      }
    }
  }
  AttendanceHistory: {
    screen: AttendanceHistory,
    navigationOptions: ({ navigation }) => {
      return {
        headerTitle: "Attendance history"
      }
    }
  },
  OrderHistory: {
    screen: OrderHistory,
    navigationOptions: ({ navigation }) => {
      return {
        headerTitle: "Order history"
      }
    }
  }
});

跟進答案，刪除以下內容。 這樣標題將在指定的屏幕上呈現：

 export default class SingleContact extends Component {
    static navigationOptions = {

        header: null, // remove this
    }
    constructor(props) {
        super(props);
        this.state = { userName: "", contacts: [], userID: "", cookie: null, memberShips: [] };
    }
    async componentDidMount() {

    }
    onDataLoaded(result, userName) {

    }
    render() {

// ------------------------------ //

const FamilyMembersStack  = createStackNavigator({
  FamilyMembers: {
    screen: FamilyMembers,
    navigationOptions: ({ navigation }) => {     
      return {
        headerTitle: "Family members",
        header:null        
      }
    }
  },
  SingleContact: {
    screen: SingleContact,
    navigationOptions: ({ navigation }) => {     
      return {
        headerTitle: "Contact",
        header:null // and remove this        
      }
    }
  },
});
