console.error : "fontFamily "Material Icons" is not a system font and has not been loaded through Font.loadAsync
console.error : "fontFamily "Material Icons" is not a system font and has not been loaded through Font.loadAsync
我正在尝试添加来自 react-native-vector-icons/MaterialIcons 的图标:
import Icon from 'react-native-vector-icons/MaterialIcons';
<View style={styles.picture}>
{ <Icon
name="add-circle"
onPress={() => alert("Add Picture")}
color="green"
/> }
</View>
但我得到:
console.error : "fontFamily "Material Icons" is not a system font and
has not been loaded through Font.loadAsync
我尝试使用 Font.loadAsync
await Font.loadAsync({'MaterialIcons': require('@expo/vector-icons/fonts/MaterialIcons.ttf')})
有什么想法吗?
在使用 Expo 时,最好使用内置的图标。
Expo 实际上自带 react-native-vector-icons
。所以你不需要安装任何东西。您可以只从 @expo/vector-icons
导入图标
https://docs.expo.io/versions/latest/guides/icons/
import { MaterialIcons } from '@expo/vector-icons';
<MaterialIcons
name="add-circle"
onPress={() => alert("Add Picture")}
color="green"
/>
还值得检查图标是否存在,您可以在 directory 中执行此操作。
