如何设置选择器的边框

Question

我有来自“ react-native ”的Picker 。Picker.Item 有："Monday、Tuesday、Wednesday etc"。我想设置选择器的属性，如 borderRadius:10甚至style={{borderRadius:30}}没有帮助。<Picker        style={styles.pickerStyle}        tvParallaxTiltAngle        selectedValue={this.props.shift}        onValueChange={value => this.props.employeeUpdate({ prop:     'shift', value })}      >        <Picker.Item color="#A4A4A5" label="Monday" value="Monday"      />        <Picker.Item color="#A4A4A5" label="Thuesday"     value="Thuesday" />        <Picker.Item color="#A4A4A5" label="Wednesdady"     value="Wednesdady" />        <Picker.Item color="#A4A4A5" label="Thursday"     value="Thursday" />        <Picker.Item color="#A4A4A5" label="Friday" value="Friday"     />        <Picker.Item color="#A4A4A5" label="Saturday"     value="Saturday" />        <Picker.Item color="#A4A4A5" label="Sunday" value="Sunday"     /></Picker>

Answer 1

你可以像这样包裹你的<Picker>内部<View>：

<View

  style={{flex: 1,

  justifyContent: 'center',

  alignItems: 'center',

  alignSelf: 'stretch',

  borderWidth: 1,

  borderRadius: 10

}}>

    <Picker>

        ...

    </Picker>

</View>
