【问题描述】:
我很难将变量“gps_location”中包含的数据转换为字符串,这将允许我使用数据。
我尝试使用 str(variable) 转换为字符串,但这没有奏效,还在变量末尾添加了 .show 和 .text
from kivy.lang import Builder
from plyer import gps
from kivy.app import App
from kivy.properties import StringProperty
from kivy.clock import Clock
kv = '''
BoxLayout:
orientation: 'vertical'
Label:
text: app.gps_info
Label:
text: app.gps_location
Label:
text: app.gps_status
BoxLayout:
size_hint_y: None
height: '48dp'
padding: '4dp'
ToggleButton:
text: 'Start' if self.state == 'normal' else 'Stop'
on_state: app.gps.start() if self.state == 'down' else app.gps.stop()
'''
def mainthread(func):
# This method is now part of Kivy 1.8.0. When it's released, remove it.
def delayed_func(*args, **kwargs):
def callback_func(dt):
func(*args, **kwargs)
Clock.schedule_once(callback_func, 0)
return delayed_func
class GpsTest(App):
gps_location = StringProperty()
gps_status = StringProperty('Click Start to get GPS location updates')
gps_info = str(gps_location)
def build(self):
self.gps = gps
try:
self.gps.configure(on_location=self.on_location,
on_status=self.on_status)
except NotImplementedError:
import traceback; traceback.print_exc()
self.gps_status = 'GPS is not implemented for your platform'
return Builder.load_string(kv)
@mainthread
def on_location(self, **kwargs):
self.gps_location = '\n'.join([
'{}={}'.format(k, v) for k, v in kwargs.items()])
@mainthread
def on_status(self, stype, status):
self.gps_status = 'type={}\n{}'.format(stype, status)
if __name__ == '__main__':
GpsTest().run()
感谢您的宝贵时间
