我有一个使用expo的React本机代码,带有带有文本的图形。在Apple中,此应用程序显示两次。在Android中,一次。
这是代码:
import { ScrollView, StyleSheet, Text, View, Alert, Dimensions } from 'react-native';
...
// Charts
import * as scale from 'd3-scale'
import { ProgressCircle, LineChart, XAxis, Grid } from 'react-native-svg-charts';
.... <Other Code> ...
<View style={{ flexDirection: 'row', justifyContent: 'space-between' }}>
<View style={{ padding: 10 }}>
<ProgressCircle
style={{ height: 150, width: 150 }}
startAngle={-Math.PI * 0.5}
endAngle={Math.PI * 0.5}
progress={this.state.perFirstTier}
progressColor={constants.BGC_GREEN}
strokeWidth={10}>
{* THIS IS WHAT IS DOUBLED*}
<Text key ='percentage' style={{
position: "absolute",
marginLeft: 65, marginTop: 50
}}>{(this.state.perFirstTier * 100).toFixed(0)}%</Text>
</ProgressCircle>
<View style={{ marginTop: -40, flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<Text style={styles.description}>{i18n.t('activityDashboard.firstGoalDesc')}</Text>
{/* Show colored badge if 100%*/}
{this.state.perSecondTier == 1
? <Image style={styles.medalImage} source={require('../../utils/images/silver_medal.png')}></Image>
: <Image style={styles.medalImage} source={require('../../utils/images/grey_medal.png')}></Image>
}
</View>
</View>
以下是Apple与Android的图像比较:
为什么会发生这种情况,如何使它只显示一次?

因为已经在ProgressCircle组件中声明了进度,并将其呈现在其中。只需从ProgressCircle中删除Text组件即可。我猜它在Android上已经隐藏了溢出,因此没有显示在那里。

如果其他所有方法均失败,请尝试为iOS平台添加渲染条件。
<ProgressCircle
style={{ height: 150, width: 150 }}
startAngle={-Math.PI * 0.5}
endAngle={Math.PI * 0.5}
progress={this.state.perFirstTier}
progressColor={constants.BGC_GREEN}
strokeWidth={10}
>
{/* THIS IS WHAT IS DOUBLED */}
{Platform.OS === 'ios'
? <View />
: (
<View>
<Text
key ='percentage'
style={{
position: "absolute",
marginLeft: 65,
marginTop: 50
}}
>
{(this.state.perFirstTier * 100).toFixed(0)}%
</Text>
</View>
)
}
</ProgressCircle>

我在尝试在 iOS14 上将 YAxis 呈现为
我的规格:
Private Sub Worksheet_Change(ByVal Target As Range)
if Target.Address = Range("Product").Address then
Activesheet.Unprotect
Range("Everything Except Country").Locked = False
Range("Country").Locked = True
Activesheet.Protect
end if
End Sub
代码:
{
"expo": "~39.0.2",
"react-native-svg-charts": "^5.4.0",
"react-native-svg": "12.1.0"
}
结果
我需要做的是将
更改的代码:
const Values = ({ x, y, data }) => {
return (
data.map((value, index) => {
return (
<Text
key={index}
style={{
color: '#6e6969',
fontSize: 10,
position: 'absolute',
left: x(index) + 1,
top: y(value) - 15
}}
>
{value}
</Text>
)
})
)}
<BarChart
style={styles.chart}
data={data.plot}
spacing={0.2}
svg={{ fill: 'rgba(134, 65, 244, 0.8)' }}
contentInset={{ top: 20, bottom: 20, left: 0, right: 0 }}
>
<Values />
</BarChart>
<XAxis
style={{ marginHorizontal: -10 }}
data={data.plot}
formatLabel={(value, index) => data.labels[index]}
contentInset={{ left: 30, right: 30 }}
svg={{ fontSize: 10, fill: colors.medium }}
/>
结果
但这两个代码在Android上都能正常工作。
