我希望我的导航抽屉在按下其中的按钮时关闭,但它没有关闭。我试过 drawerLayout.closeDrawer(GravityCompat.START) 和 drawerLayout.closeDrawers();但这些在这方面似乎不起作用。
我的 MainActivity.java
library(shiny)
library(ggplot2)
library(dplyr)
shinyServer(function(input, output) {
output$ufoPlot <- renderPlot({
ufo_data_filter <- filter(ufo_data, Country == input$Country)
ggplot(data = ufo_data_filter) +
geom_bar(mapping = aes(x = Shape))+
labs(
title = "Number of Different Shaped UFO Observations",
x = "Shape of UFO Sighted",
y = "Number of Observations in 2016"
)
})
})
这是我的 activity_main.xml 我的组件顺序不正确吗?在这方面重要吗?
