如果你要使用react-native-vector-icon要容易得多,只需创建一个类似于我在下面创建的数组,对于你想要使用的图标的所有名称,如果你想使用图像,那么您将不得不使用图像链接,因为我上次检查本机反应将不允许您动态加载静态资产。
使用图标的好处特别是react-native-vector-icon:
`
.....
import Icon from 'react-native-vector-icons/Ionicons';
const styles = {
body: {
backgroundColor: '#3b4147',
height: 60,
},
tabWrapper: {
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
height: 50,
},
tabInnerWrapper: {
marginRight: 12,
marginLeft: 12,
justifyContent: 'center',
alignItems: 'center',
},
textStyle: {
fontSize: 12,
color: '#62666b',
},
focusTextStyle: {
fontSize: 12,
color: '#acafb1',
},
};
const {body, tabWrapper, tabInnerWrapper, textStyle, focusTextStyle} = styles;
const focusIconColor = '#acafb1';
const iconColor = '#62666b';
const IconNames = ['ios-compass-outline', 'ios-cut-outline', 'ios-chatboxes-outline'];
const IconNamesFocus = ['ios-compass', 'ios-cut', 'ios-chatboxes'];
const CustomTabBar = ({ navigation: { state, navigate }}) => {
const { routes } = state;
return (
<View style={body}>
<View style={tabWrapper}>
{routes && routes.map((route, index) => {
const focused = index === state.index;
return (
<TouchableOpacity
key={route.key}
onPress={() => navigate(route.routeName)}
style={tabInnerWrapper}
>
<Icon
name={focused ? IconNamesFocus[index] : IconNames[index]}
size={25}
color={focused ? focusIconColor : iconColor}
/>
<Text style={focused ? focusTextStyle : textStyle}>
{route.routeName}
</Text>
</TouchableOpacity>
);
})}
</View>
</View>
);
};
`
