在暂停代码中,我尝试将3个元素添加到一起,但它失败并且按钮未在输出中显示
<ion-content>
<ion-item>
<ion-label fixed>Origin</ion-label>
<ion-input type="text" value=""></ion-input>
<ion-buttons end>
<button ion-button icon-only>
<ion-icon name="locate"></ion-icon>
</button>
</ion-buttons>
</ion-item>
<ion-item>
<ion-label fixed>Target</ion-label>
<ion-input type="text" value=""></ion-input>
<ion-buttons end>
<button ion-button icon-only>
<ion-icon name="locate"></ion-icon>
</button>
</ion-buttons>
</ion-item>
<button ion-button full>Start</button>
</ion-content>
它分别显示每个项目或带有标签的文本,但按钮没有显示在文本框的末尾。

这样做的一种方法是使用ion-row,ion-col以您需要的格式进行排列。检查here 例如:
from tkinter import *
import requests
from lxml import html
window = Tk()
window.title('Craigslist Apartment Finder')
window.resizable(width=False, height=True)
def getSearch():
s1 = searchterm1.get()
s2 = searchterm2.get()
s3 = searchterm3.get()
if s1 != "":
url = "https://newyork.craigslist.org/search/brk/roo?sort=date&availabilityMode=0&query=" + s1
if s2 != "":
url = url + "+" + s2
if s3 != "":
url = url + "+" + s3
if s1 != "" or s2 != "" or s3 != "":
print(url)
else:
print("No search terms entered.")
page = requests.get(url)
print(page)
tree = html.fromstring(page.content)
price = tree.xpath('//span[class="result-price"]/text()')
print("Prices:", price)
searchterm1 = Entry(window)
searchterm2 = Entry(window)
searchterm3 = Entry(window)
programname = Label(window, text="Apartment Finder")
runbutton = Button(window, text="Run", bg="green", fg="white", width=10, command=getSearch)
displayurl = Label(window, text="url")
programname.grid(row=0, column=0, columnspan=2)
runbutton.grid(row=0, column=2)
searchterm1.grid(row=1, column=0)
searchterm2.grid(row=1, column=1)
searchterm3.grid(row=1, column=2)
displayurl.grid(row=2, column=0, columnspan=3)
window.mainloop()
