我使用的是ScrollView
,我无法将内部View
内的图标居中。
import Icon from 'react-native-vector-icons/MaterialCommunityIcons';
<ScrollView>
...
<View style={styles.detailRowContainer}>
<View style={{flex: 1}}>
<Text style={styles.label} numberOfLines={1}>
{'Phone Number'}
</Text>
<Text style={styles.value} numberOfLines={1}>
{phone}
</Text>
</View>
<View style={styles.round}>
<TouchableWithoutFeedback onPress={this._onPressPhone}>
<Icon size={22} name="phone" />
</TouchableWithoutFeedback>
</View>
</View>;
...
</ScrollView>
detailRowContainer: {
flexDirection: 'row',
justifyContent: 'center',
flex: 1,
marginTop: 10,
paddingBottom: 10,
borderBottomWidth: 1,
borderBottomColor: Colors.lightGray,
},
label: {
color: Colors.glofoxDark,
marginBottom: 3,
},
value: {
color: Colors.glofoxDark,
fontWeight: '800',
borderBottomWidth: 1,
borderBottomColor: Colors.lightGray,
},
round: {
backgroundColor: Colors.lightBlue,
width: 30,
height: 30,
borderRadius: 30,
overflow: 'hidden',
justifyContent: 'center',
alignItems: 'flex-end',
flexDirection: 'row',
padding: 4,
},
答案 0 :(得分:2)
需要以这种方式修改样式。
现在你正在做
flexDirection: row
沿着justifyContent: center
。由于您的第一个子元素正在完成父级flex ,因此它不会显示其效果paddingBottom
但是,为了居中,必须给出等效的paddingTop
padding
应替换为margin
,否则会影响内部元素的位置alignItems
一轮,不得为flex-end
,应替换为center
以下是修复垂直居中
的样式 detailRowContainer: {
flexDirection: 'row',
alignItems: 'center',
flex: 1,
marginTop: 10,
paddingTop: 10,
paddingBottom: 10,
borderBottomWidth: 1,
borderBottomColor: Colors.lightGray,
},
round: {
backgroundColor: Colors.lightBlue,
width: 30,
height: 30,
borderRadius: 30,
overflow: 'hidden',
justifyContent: 'center',
alignItems: 'center',
margin: 4
},
