Answer 1

我刚刚通过导入以下库解决了涉及library(sf) library(sp) library(ggplot2) library(dplyr) sf_states %>% filter(!(NAME_1 %in% c("Alaska","Hawaii"))) %>% mutate(COLOR = ifelse(NAME_1 %in% c("Oregon","Florida"),"green","red")) %>% ggplot() + geom_sf(aes(fill = COLOR), show.legend = FALSE)+ scale_fill_identity()的问题：

sf_states %>% filter(!(NAME_1 %in% c("Alaska","Hawaii"))) %>% mutate(COLOR = ifelse(NAME_1 %in% c("Oregon","Florida"),1,0)) %>% ggplot() + geom_sf(aes(fill = as.factor(COLOR)), show.legend = FALSE)+ scale_fill_manual(values = c("red","green"))

如果您未添加以下依赖项，请将其添加到build.gradle（Module：app）

dependencies {
//other dependencies
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
}

要从旧的构建工件中了解新的Androidx工件的等效内容，请参阅以下链接
