[英]React Native: elevation (shadow) and transparency on button don't work together as needed
[英]React Native Elevation shadow does not work properly
我是 React Native 的新手,我嘗試為我的單選按鈕創建一個組件,但是在添加高程時遇到了 Style 的一些問題,它在View
內而不是View
外添加陰影
這是我的代碼
import {Text, View, StyleSheet} from 'react-native';
import {RadioButton} from 'react-native-paper';
import {
ScrollView,
TextInput,
TouchableOpacity,
} from "react-native-gesture-handler";
function Chosen({values, onChange, defaultIndex, selectedIndexAtt, renderComponent}){
const [index, setIndex] = useState(defaultIndex ? defaultIndex : 0);
const getRadioStatus = (itemIndex) => {
return index == itemIndex ? 'checked' : 'unchecked';
}
const handleRadioPress = (itemIndex) => {
setIndex(itemIndex);
onChange(itemIndex);
}
return(
<ScrollView style={styles.container}>
<View style={styles.containerRow}>
{values.map((item, index)=> {
return (<View style={styles.itemContainer}>
<View style={styles.item}>
{renderComponent(item)}
<View style={styles.radioButton}>
<RadioButton value={item[selectedIndexAtt ? selectedIndexAtt : index]}
status={getRadioStatus(item[selectedIndexAtt ? selectedIndexAtt : index])}
onPress={() => {
handleRadioPress(item[selectedIndexAtt ? selectedIndexAtt : index])
}}/>
</View>
</View>
</View>)
})}
</View>
</ScrollView>
);
}
const styles = StyleSheet.create({
container:{
flexDirection: 'column',
flex: 1
},
containerRow:{
flexDirection: 'row',
flexWrap: 'wrap',
},
itemContainer: {
width: "50%",
padding: 1
},
item: {
flexDirection: 'row',
margin: 10,
borderWidth: 1,
borderColor: 'rgba(105,105,105,0.6)',
borderRadius: 15,
elevation: 0.1
},
radioButton: {
justifyContent: 'center',
flex: 1,
alignItems: 'flex-end'
}
});
export default Chosen;
這就是我從父母那里稱呼它的方式
<Chosen values={dummyData} defaultIndex={dummyData[0].id} selectedIndexAtt='id' renderComponent={(item) => {
return (
<View>
<Text>{item.name}</Text>
</View>
)
}} onChange={onChange}></Chosen>
結果是這樣的:
有人可以幫我嗎?
您必須為 react native 中的陰影提供此功能。 根據需要更改值。
shadowColor: "#000",
shadowOffset: {
width: 0,
height: 10,
},
shadowOpacity: 0.5,
shadowRadius: 10,
elevation: 20,
