我在 FlatList 中遇到了 TouchableOpacity 和 Negative Margins 的问题。在 iOS 上运行良好,但在 Android 上,当我单击其他 TochableOpacity 前面的 TouchableOpacity 时,后面的 TouchableOpacity 会触发。我不知道如何解决这个问题。
我点击了“Proposta 70”,但从后面发射了“Proposta 78”。 Android Image
FlatList 代码
<View style={styles.containerList}>
<FlatList
data={proposalsList}
keyExtractor={item => item.proposta_id}
renderItem={({ item, index }) => (
<RenderItem
item={item}
index={index}
isLoweredCard={
openedCardIndex !== null && index === openedCardIndex + 1
}
changeOpenedCardIndex={changeOpenedCardIndex}
/>
)}
refreshing={loading}
onRefresh={() => getProposalsAndNotifications()}
/>
</View>
RenderItem 代码
<TouchableOpacity
style={styles.container(index, isLoweredCard)}
onPress={() => changeOpenedCardIndex(index)}
>
<>
<View
style={[
styles.lineContainer,
{ marginBottom: metrics.padding * 1.5 },
]}
>
<View
style={{
width: '50%',
}}
>
<Text style={styles.proposalId}>
{`Proposta ${item.proposta_id}`}
</Text>
<Text style={styles.proposalDate}>
{dayjs(item?.proposta_data_criacao).format('DD.MM.YYYY')}
</Text>
</View>
<View
style={{
flex: 1,
justifyContent: 'center',
alignItems: 'flex-end',
}}
>
<View style={styles.statusContainer}>
<Text style={{ fontSize: wp(4), fontWeight: 'bold' }}>
<TypeStatus status={item?.proposta_status} />
</Text>
</View>
</View>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Valor solicitado</Text>
<Text style={styles.proposalDetailValue}>
{formatCurrency(item?.proposta_valor_financiado)}
</Text>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Valor liberado</Text>
<Text style={styles.proposalDetailValue}>
{formatCurrency(item?.proposta_valor_financiado)}
</Text>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Parcelas</Text>
<Text style={styles.proposalDetailValue}>
{`${item?.proposta_valor_prazo}x`}
</Text>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Valor da parcela</Text>
<Text style={styles.proposalDetailValue}>
{formatCurrency(item?.proposta_valor_parcela)}
</Text>
</View>
<View style={styles.buttonContainer}>
<Button
onPress={goToDetails}
title="Ver detalhes"
titleStyle={styles.proposalButtonText}
style={styles.button}
/>
</View>
</>
</TouchableOpacity>
以及物品的风格
import {
widthPercentageToDP as wp,
heightPercentageToDP as hp,
} from 'react-native-responsive-screen';
import { metrics, colors } from '../../../../constants';
const styles = StyleSheet.create({
container: (index, isLoweredCard) => ({
backgroundColor: `#00${index}F${index}C`,
marginTop: !isLoweredCard && index !== 0 ? -wp(53) : metrics.padding,
marginHorizontal: metrics.padding,
alignContent: 'center',
padding: metrics.padding,
borderRadius: metrics.radius,
zIndex: -(index + 999),
}),
lineContainer: {
width: '100%',
justifyContent: 'space-between',
flexDirection: 'row',
marginBottom: metrics.padding / 2,
},
statusContainer: {
backgroundColor: colors.white,
borderRadius: 20,
width: '70%',
paddingVertical: 3,
alignItems: 'center',
justifyContent: 'center',
},
proposalId: {
color: colors.white,
fontWeight: 'bold',
fontSize: wp(4.5),
},
proposalDate: {
color: 'rgba(0, 0, 0, 0.5)',
fontWeight: 'bold',
fontSize: wp(3.5),
},
proposalDetailLabel: {
fontSize: wp(4),
color: 'rgba(0, 0, 0, 0.9)',
},
proposalDetailValue: {
fontSize: wp(4.5),
color: colors.white,
fontWeight: 'bold',
},
proposalButtonText: {
color: colors.white,
fontWeight: 'bold',
fontSize: wp(4),
},
button: {
borderRadius: metrics.radius,
backgroundColor: '#002F6C',
paddingHorizontal: metrics.padding * 3,
},
buttonContainer: {
width: '100%',
marginTop: metrics.padding,
alignItems: 'center',
},
});
export default styles;
答案 0 :(得分:0)
我在 Android 上遇到了完全相同的问题。 My FlatList
rendered items with negative margin to superimpose them on each other。 iOS 上的 touchable 是完美的,但在 Android 上它按下了后面最低的项目。
最后我通过替换解决了这个问题
import { TouchableOpacity } from 'react-native';
与
import { TouchableOpacity } from 'react-native-gesture-handler';
在我的情况下使用 react-native
0.63.4 和 react-native-gesture-handler
1.9.0。
