在 React Native 中更改应用背景颜色 [英] Change app background color in React Native

问题描述

我正在尝试将 React Native 应用程序的背景颜色从灰色更改为白色.我在渲染后使用 react-navigation 制作一个 TabNavigator.我试图将这个 TabNavigator 放在一个视图中并设置 backgroundColor 但所有屏幕都变成了白色.我该如何解决这个问题?

I'm trying to change the color of the background in my react native app, from grey to white. I'm using react-navigation to make a TabNavigator after I render it. I tried to put this TabNavigator in a view and set backgroundColor but all screen became white. How can I solve this?

index.js

...
render() {
    return (
        <View style={{ backgroundColor: '#FFFFFF'}}>
            <Tabs />
        </View>
    )
  }
...

标签

...
const Tabs = TabNavigator(
  {
    Home: {
      screen: HomeStack,
      navigationOptions: {
        title: 'Acasa',
      },
    },
    ...
    Account: {
      screen: AccountScreen,
      navigationOptions: {
        title: 'Contul meu',
      },
    },
  },
  {
    tabBarComponent: props => <FooterNavigation {...props} />,
    tabBarPosition: 'bottom',
    initialRouteName: 'Home',
  },
);
...

主屏幕

render() {
    const {
      data, refreshing, loading, error,
    } = this.state;

    return (
      <ScrollView>
        <Container>
          {error && <Text>Error</Text>}
          {loading && <ActivityIndicator animating size="large" />}

          <List>
            <FlatList
              data={data}
              renderItem={({ item }) => (
                <ListItem onPress={() => this.props.navigation.navigate('Item', item)}>
                  <Item data={item} />
                </ListItem>
              )}
              // ID from database as a key
              keyExtractor={item => item.title}
              ItemSeparatorComponent={this.renderSeparator}
              ListFooterComponent={this.renderFooter}
              ListHeaderComponent={this.renderHeader}
              refreshing={refreshing}
              onRefresh={this.handleRefresh}
              onEndReached={this.handleLoadMore}
              onEndReachedThreshold={0}
            />
          </List>
        </Container>
      </ScrollView>
    );
  }

推荐答案

我已经解决了我的问题，它是由 StackNavigator 引起的.要解决它，只需添加一些额外的选项

I've solved my problem, it was caused by StackNavigator. To solve it , just add some extra options

    const HomeStack = StackNavigator(
  {
    Home: {
      screen: HomeScreen,
    },
    Item: {
      screen: ItemScreen,
      navigationOptions: ({ navigation }) => ({
        title: `${navigation.state.params.title}`,
      }),
    },
  },
  **
  {
    headerMode: 'screen',
    cardStyle: { backgroundColor: '#FFFFFF' },
  },
  **
);
