kivy 使用webview加载网页

kivy app内访问网页 直接上源码， 

webview.py

from kivy.app import App

from kivy.uix.widget import Widget
from kivy.clock import Clock
from jnius import autoclass
from android.runnable import run_on_ui_thread

WebView = autoclass(‘android.webkit.WebView’)
WebViewClient = autoclass(‘android.webkit.WebViewClient’)
#activity = autoclass(‘org.renpy.android.PythonActivity’).mActivity
activity = autoclass(‘org.kivy.android.PythonActivity’).mActivity

class Wv(Widget):
def __init__(self, **kwargs):
super(Wv, self).__init__(**kwargs)
Clock.schedule_once(self.create_webview, 0)

@run_on_ui_thread
def create_webview(self, *args):
webview = WebView(activity)
settings = webview.getSettings()
settings.setJavaScriptEnabled(True)
settings.setUseWideViewPort(True) # enables viewport html meta tags
settings.setLoadWithOverviewMode(True) # uses viewport
settings.setSupportZoom(True) # enables zoom
settings.setBuiltInZoomControls(True) # enables zoom controls
wvc = WebViewClient()
webview.setWebViewClient(wvc)
activity.setContentView(webview)
webview.loadUrl(‘http://beta.html5test.com’)

class ServiceApp(App):
def build(self):
return Wv()

if __name__ == ‘__main__’:
ServiceApp().run()
