推荐答案

您必须从URL构建内容URI.有几种方法可以做到这一点.

You have to build content URI from the url. There are several ways to do this.

一种方法是从URL下载图像并从下载的文件构建URI.

One way is to build that is download image from url and build URI from the downloaded file.

如果您正在使用 Glide 从网址加载图片，则可以通过以下方式完成:

If you are using Glide to load image from url, then it can be done in following way:

Glide.with(context).asBitmap().load(photoUrl)
        .into(object: CustomTarget<Bitmap>() {

            override fun onLoadCleared(placeholder: Drawable?) {
                // do your stuff, you can load placeholder image here
            }

            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {


                val cachePath = File(context.cacheDir, "images")
                cachePath.mkdirs() // don't forget to make the directory
                val stream = FileOutputStream(cachePath.toString() + "/image.png") // overwrites this image every time
                resource.compress(Bitmap.CompressFormat.PNG, 100, stream)
                stream.close()

                val imagePath = File(context.cacheDir, "images")
                val newFile = File(imagePath, "image.png")
                val contentUri: Uri = FileProvider.getUriForFile(context, "${BuildConfig.APPLICATION_ID}.provider", newFile)

                val intent = Intent(Intent.ACTION_SEND)
                intent.type = "image/*"
                intent.putExtra(Intent.EXTRA_STREAM, contentUri)
                context.startActivity(Intent.createChooser(intent, "Choose..."))

            }
        })

别忘了在清单中添加provider:

    <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>

和provider_paths

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <cache-path name="cache" path="/" />
</paths>
