我想制作一个带有按钮的kivy应用程序,当点击按钮时打开android gallary。 所以我写了代码,你可以在qpython上看到它,并且它有效。 但是当我想在我的电脑上运行它时,我收到了错误消息:

     Traceback (most recent call last):
   File "main.py", line 35, in <module>
     from gallery import Gallary
   File "/home/gilgamesch/Apps/event/gallery.py", line 14, in <module>
     from android import activity
 ImportError: No module named android

(是的,这是整个错误消息)

但无论如何我决定尝试一下。 所以我用buildozer编译它,安装并在我的Android手机上启动它,应用程序启动了。 它打开了,我点击了他的按钮,并且也打开了gallary,但是当我选择一个图像时,程序就崩溃了。

这是main.py:

#-*-coding:utf8;-*-
#qpy:2
#qpy:kivy

from kivy.app import App
from kivy.uix.button import Button
from kivy.properties import StringProperty

from gallery import Gallary


class TestApp(App):
    path = StringProperty()
    def build(self):


        return Button(text='Hello QPython', on_release=self.open_g)
    def open_g(self, *args):
        self.g = Gallary()

        path = self.g.make_gallary(self.getstr)

    def getstr(self, path):
        self.path = path
        print self.path + 'in Gallary class'

    def on_pause(self):
        return True

    def on_resume(self):
        pass


TestApp().run()

这是我自制的Gallary模块:

#-*-coding:utf8;-*-
#qpy:2
#qpy:kivy

from jnius import autoclass
from jnius import cast

from android import activity


class Gallary(object):
    def __init__(self, *args):

        self.mypath = ''

        # import the needed Java class 
        self.PythonActivity = autoclass ('org.renpy.android.PythonActivity')
        self.Activity = autoclass('android.app.Activity')

        self.uri = autoclass('android.net.Uri')
        self.intent = autoclass('android.content.Intent')
        self.MediaStore = autoclass('android.provider.MediaStore')
        self.Cursor = autoclass('android.database.Cursor')


        # Value of MediaStore.Images.Media.DATA
        self.MediaStore_Images_Media_DATA = "_data"



        self.gallerie = self.intent()
        self.gallerie.setType("image/*")
        self.gallerie.setAction(self.intent.ACTION_GET_CONTENT)



    def getPath(self, Iuri, *args):
        if Iuri == None:
            return ''
        self.projektion = [self.MediaStore_Images_Media_DATA]

        self.cursor = self.currentActivity.getContentResolver().query(Iuri, self.projektion, None, None, None)
        if self.cursor != None:
            cindex = self.cursor.getColumnIndexOrThrow(self.MediaStore_Images_Media_DATA)
            self.cursor.moveToFirst()
            return self.cursor.getString(cindex)
        return Iuri.getPath()

    def on_activity_result(self, requestCode, resultCode, data):

        print "### ACTIVITY CALLBACK ###"
        if resultCode == self.PythonActivity.RESULT_OK:
            if requestCode == 1:

                myuri = data.getData()
                self.mypath = self.getPath(myuri)
                self.give(self.mypath)
                #print self.mypath

    def make_gallary(self, give):

        self.currentActivity = cast('android.app.Activity', self.PythonActivity.mActivity)
        self.currentActivity.startActivityForResult(self.intent.createChooser(self.gallerie, "Choose Image"), 1)
        #print 'made gallery'
        self.give = give

        activity.bind(on_activity_result=self.on_activity_result)

        return self.mypath

    def get_str(self):
        return self.mypath
    def give(self):
     pass

以下是权限,我在buildozer.spec文件中提供了应用程序:

# (list) Permissions
android.permissions = INTERNET,ACCESS_WIFI_STATE,READ_PHONE_STATE,ACCESS_NETWORK_STATE,READ_EXTERNAL_STORAGE,WRITE_EXTERNAL_STORAGE

以下是逻辑分析的一部分,其中包含了一些内容:
