我用于@react-native-community/slider我的应用程序，但我面临一个问题，它的高度没有改变，它的宽度在改变，但高度没有改变，有人知道为什么吗？而且我想渲染滑块的值，就像滑块拇指内的蓝色容器一样，有没有办法做到这一点？请帮忙

这是我的滑块代码

<View>
          <Text style={[style.fontSize15Med, styles.font15]}>
            Number of surveys
          </Text>
          <View style={styles.daysCont}>
            <Text style={[style.fontSize12Med, styles.surveys]}>
              {this.state.surveys}
            </Text>
          </View>
          <Slider
            style={{width: 320, height: 30, marginLeft: 40}}
            minimumValue={0}
            maximumValue={10}
            step={1}
            maximumTrackTintColor={colors.DarkBlue}
            minimumTrackTintColor={colors.primary}
            thumbTintColor={colors.skyBlue}
            value={this.state.surveys}
            onValueChange={(val) => this.setState({surveys: val})}
          />
        </View>

我怎样才能让我的平面列表看起来像这样？是否有任何道具可以实现这一点，或者我需要使用哪种样式来做到这一点？

          user = self.request.user
          if user.is_authenticated:
             if user in obj.likes.all():
                obj.likes.remove(user)
             else:
                obj.likes.add(user)
          return url_

        def get(self, request, format=None):

            return Response(usernames) …
