不幸的是,stacknavigator只在顶部呈现白色背景,我猜标题的样式没有生效?我想知道原因和解决方法是什么?不完全是针对您的问题的解决方法,更像是一种解决方法。 我发现使用来自react原生元素的header组件定制header更容易。只需为每个屏幕添加您想要显示的组件。然后使用header:null隐藏堆栈导航器上的头,否则可能会得到两个头 示例如下:
<React.Fragment>
<Header
statusBarProps={{ barStyle: 'light-content' }}
barStyle="light-content"
leftComponent={
<SimpleIcon
name="menu"
color="#34495e"
size={20}
/>
}
centerComponent={{ text: 'HOME', style: { color: '#34495e' } }}
containerStyle={{
backgroundColor: 'white',
justifyContent: 'space-around',
}}
/>
</React.Fragment>
