scrollview 相关问题

我收到此错误这是我的代码我收到此错误这是我的代码 <ImageBackground source={BG} style={{ flex: 1 }}> <ScrollView horizontal style={{ flex: 1, height: '100%' }}> <View style={{ paddingTop: '10%' }}> <Text style={[styles.bold, styles.textCenter, { fontSize: 18, color: c.yellow }]}>Data</Text> <View style={[styles.row, styles.justifyBetween, { width: '100%', paddingHorizontal: '5%', borderTopWidth: 1, borderBottomWidth: 1, borderColor: c.yellow }]}> <Text style={[styles.textWhite, { width: '10%' }]}>Sr.</Text> <Text style={[styles.textWhite, { width: '20%' }]}>User ID</Text> <Text style={[styles.textWhite, { width: '20%' }]}>Name</Text> <Text style={[styles.textWhite, { width: '25%' }]}>Phone</Text> <Text style={[styles.textWhite, styles.textCenter, { width: '20%' }]}>Active</Text> <Text style={[styles.textWhite, { width: '25%' }]}>Time/Date</Text> </View> </View> {loading ? <ActivityIndicator color={c.yellow} size='large' style={{ marginTop: '20%' }} /> : data.length > 0 ? <FlatList data={data} keyExtractor={(item, index) => index.id} renderItem={dataList} style={{ width: '100%', paddingHorizontal: '1%', marginTop: '5%' }} /> : <Text style={[styles.textWhite, styles.textCenter, styles.bold, { fontSize: 20, marginTop: '20%' }]}>No Data Found!</Text> } </ScrollView> </ImageBackground> 我的RN版本是0.70.6 我正在使用 Ubuntu 22.04 LTS 我在物理设备上而不是模拟器上运行此应用程序 NodeJS 版本 16.18.1 JDK信息 - openjdk 11.0.17 2022-10-18 Android Studio 海豚 2021.3.1 这是我的依赖者 "@react-native-async-storage/async-storage": "^1.17.11", "@react-native-community/blur": "^4.3.0", "@react-native-community/clipboard": "^1.5.1", "@react-native-masked-view/masked-view": "^0.2.8", "@react-native-picker/picker": "^2.4.8", "@react-navigation/native": "^6.0.13", "@react-navigation/stack": "^6.3.4", "@reduxjs/toolkit": "^1.9.0", "axios": "0.27", "react": "18.1.0", "react-native": "0.70.6", "react-native-elements": "^3.4.2", "react-native-gesture-handler": "^2.8.0", "react-native-image-crop-picker": "^0.38.1", "react-native-paper": "^4.12.5", "react-native-qrcode-svg": "^6.1.2", "react-native-reanimated": "^2.13.0", "react-native-safe-area-context": "^4.4.1", "react-native-screens": "^3.18.2", "react-native-splash-screen": "^3.3.0", "react-native-svg": "^13.6.0", "react-native-vector-icons": "^9.2.0", "react-redux": "^8.0.5" 我已经搜索了“错误”，但一无所获。答案说这个错误是在 RN v0.56 中退出的。我想在 Horizontal ScrollView 中使用 Vertical Flatlist 不得在 ScrollVeiw 子项或平面列表项中使用百分比值 <ImageBackground source={BG} style={{ flex: 1 }}> <ScrollView horizontal style={{ flex: 1, height: '100%' }}> <View style={{ paddingTop: 70 }}>//not paddingTop:10% 从来没想过这一点，但它确实有效。太棒了！！！

在 MAUI[Android] 中，Scrollview 在 maui.community.toolkit.popup 中不起作用

我在内容页面尝试了相同的布局，它有效。它不仅仅在弹出窗口中起作用。下面是我的 XAML 代码结构。我在内容页面尝试了相同的布局，它有效。它不仅仅在弹出窗口中工作。下面是我的XAML代码结构。 <toolkit:Popup x:Class="MuniLogicMobile.View.ReportsPage" xmlns="http://schemas.microsoft.com/dotnet/2021/maui" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit" x:Name="popup" Color="Transparent"> <Border Grid.Column="1" Stroke="{x:StaticResource Secondary}" StrokeThickness="2"> <Border.StrokeShape> <RoundRectangle CornerRadius="10" /> </Border.StrokeShape> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <ScrollView Margin="10" HeightRequest="500" VerticalOptions="FillAndExpand"> <VerticalStackLayout Margin="10"> </VerticalStackLayout> </ScrollView> </Grid> </Border> </toolkit:Popup> 只需添加上面的布局并在弹出窗口中尝试。在 VerticalStackLayout 中添加更多项目。我在Android平台遇到这个问题，没有在iOS中尝试过。尝试设置滚动视图的高度，并且将 HosrizontalOptions 和 VerticalOptions 设置为 Fill 两者单独或一起都不起作用。我这边做了测试，但无法重现这个问题。我在 Android 模拟器（Pixel 5-Api 3）上进行了测试。请参考我使用的以下代码，在我这边可以正常运行。 <?xml version="1.0" encoding="utf-8" ?> <toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit" x:Class="PopUpMauiApp.MyPopPage" > <Border Grid.Column="1" Stroke="#C49B33" StrokeThickness="2"> <Border.StrokeShape> <RoundRectangle CornerRadius="10" /> </Border.StrokeShape> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <ScrollView Margin="10" HeightRequest="500" VerticalOptions="FillAndExpand"> <VerticalStackLayout Margin="10"> <Label TextColor="Red" Text="1 FOR the most wild, yet most homely narrative which I am about to pen, I neither expect nor solicit belief.
