我正在使用 native-base ui kit . 我'm trying to change the background color of selected items in sidebar. But how to do that? I'已对此 theme/variablesplatform.js 文件进行了更改 .

listBg: "#008080",
  listBorderColor: "#c9c9c9",
  listDividerBg: "#f4f4f4",
  listBtnUnderlayColor: "#008080",
  listItemPadding: platform === "ios" ? 10 : 12,
  listNoteColor: "#808080",
  listNoteSize: 13,

但看不出任何变化 . 请帮我找到任何解决方案?这就是侧边栏中的 ListItem 的样子

<List
            dataArray={datas}
            renderRow={data =>
              <ListItem
                button
                noBorder
                onPress={() => this.props.navigation.navigate(data.route)}
              >
                <Left>
                <Image
                  source={data.icon }
                  style={{width:30,height:30}}
                />
                  <Text style={styles.text}>
                    {data.name}
                  </Text>
                </Left>
                {data.types &&
                  <Right style={{ flex: 1 }}>
                    <Badge
                      style={{
                        borderRadius: 3,
                        height: 25,
                        width: 72,
                        backgroundColor: data.bg
                      }}
                    >
                      <Text
                        style={styles.badgeText}
                      >{`${data.types} Types`}</Text>
                    </Badge>
                  </Right>}
              </ListItem>}
          />

请帮我 .
