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>

你可以像这样包裹你的<Picker>内部<View>：<View&nbsp; style={{flex: 1,&nbsp; justifyContent: 'center',&nbsp; alignItems: 'center',&nbsp; alignSelf: 'stretch',&nbsp; borderWidth: 1,&nbsp; borderRadius: 10}}>&nbsp; &nbsp; <Picker>&nbsp; &nbsp; &nbsp; &nbsp; ...&nbsp; &nbsp; </Picker></View>
