Question

我正在尝试与电子邮件客户端和Google云端硬盘共享文件。现在，在以下代码中，只有Google驱动器正在打开，而电子邮件客户端根本没有打开。如果需要，我可以提供以下代码的等效Java代码

    val photoURI: Uri = FileProvider.getUriForFile(this, "com.emerson.oversight.com.emerson.oversight.provider",
            File(this.cacheDir.path + "/SensorReport.pdf"))

    val emailIntent = Intent(Intent.ACTION_SENDTO)
    emailIntent.data = Uri.parse("mailto:")

    emailIntent.putExtra(Intent.EXTRA_STREAM, photoURI)
    emailIntent.putExtra(Intent.EXTRA_EMAIL, "asd@dsa.dsa")
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "dsadsada")
    emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)

    val driveIntent = Intent()
    driveIntent.`package`= "com.google.android.apps.docs"
    driveIntent.action = Intent.ACTION_VIEW

    val fileID = File(this.cacheDir.path + "/SensorReport.pdf")
    val url = "https://docs.google.com/file/d/" + fileID

    driveIntent.data = Uri.parse(url)

        val openInChooser = Intent.createChooser(driveIntent, getString(R.string.share_using))
        openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, arrayListOf(emailIntent))
        startActivity(openInChooser)

请帮忙

你几乎就在那里，谜题中唯一缺少的部分是getPackageManager().queryIntentActivities方法，它将返回所有可以处理你的电子邮件意图的活动。返回ResolveInfo后，您可以为选择器中显示的每个电子邮件选项构建一个意图。然后，您可以将这些意图的数组作为Intent.EXTRA_INITIAL_INTENTS传递。如果您愿意，甚至可以排除某些包裹。所以代码的最后部分看起来像这样：

        val openInChooser = Intent.createChooser(driveIntent, getString(R.string.share_using))

        val emailOptionIntents = mutableListOf<Intent>()
        val resInfo = getPackageManager().queryIntentActivities(emailIntent, 0)
        if (!resInfo.isEmpty()) {
            for (resolveInfo in resInfo) {
                val emailOptionIntent = Intent(Intent.ACTION_SENDTO)
                emailOptionIntent.data = Uri.parse("mailto:")

                emailOptionIntent.putExtra(Intent.EXTRA_STREAM, photoURI)
                emailOptionIntent.putExtra(Intent.EXTRA_EMAIL, "asd@dsa.dsa")
                emailOptionIntent.putExtra(Intent.EXTRA_SUBJECT, "dsadsada")
                emailOptionIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)


                emailOptionIntent.`package` = resolveInfo.activityInfo.packageName
                emailOptionIntents.add(emailOptionIntent)
            }
        }




        openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, emailOptionIntents.toTypedArray())
        startActivity(openInChooser)

Intents使用Extra＆＃34; EXTRA_INITIAL_INTENTS＆＃34;解决的应用程序未显示
