kivy android 分享图片

问题描述

我想创建将使用 android ACTION_SEND 意图共享图像的共享按钮.这是我的代码:

I want to create share button that will use android ACTION_SEND intent for sharing image. It's my code:

from kivy.setupconfig import USE_SDL2


def share(path):
    if platform == 'android':
        from jnius import cast
        from jnius import autoclass
        if USE_SDL2:
            PythonActivity = autoclass('org.kivy.android.PythonActivity')
        else:
            PythonActivity = autoclass('org.renpy.android.PythonActivity')
        Intent = autoclass('android.content.Intent')
        String = autoclass('java.lang.String')
        Uri = autoclass('android.net.Uri')
        File = autoclass('java.io.File')

        shareIntent = Intent(Intent.ACTION_SEND)
        shareIntent.setType('"image/*"')
        imageFile = File(path)
        uri = Uri.fromFile(imageFile)
        shareIntent.putExtra(Intent.EXTRA_STREAM, uri)

        currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
        currentActivity.startActivity(shareIntent)

但它不起作用)它抛出此错误 jnius.jnius.JavaException: Invalid instance of u'android/net/Uri' passed for a u'java/lang/String' in这一行 shareIntent.putExtra(Intent.EXTRA_STREAM, uri).我该如何解决这个问题?

But it doesn't work) It throws this error jnius.jnius.JavaException: Invalid instance of u'android/net/Uri' passed for a u'java/lang/String' in this line shareIntent.putExtra(Intent.EXTRA_STREAM, uri). How can i fix this?

推荐答案

我找到了解决方案.您必须将 uri 转换为 parcelable，然后将其传递给意图:

I found solution. You must cast uri to parcelable and then pass it to intent:

parcelable = cast('android.os.Parcelable', uri)
shareIntent.putExtra(Intent.EXTRA_STREAM, parcelable)
