请勿重复进行此操作。.我尝试了每个链接，直到现在我都会按照我尝试过的方式显示
我将简要解释我的代码->
从适配器获取图像到活动->
val bundle: Bundle = getIntent().getExtras()!!
val imgUrl: String = bundle.getString("image")!!
val imageUri = Uri.parse(imgUrl)

我想分享图片需要帮助，谢谢
答案 0 :(得分：1)
您必须从URL构建内容URI。有几种方法可以做到这一点。
一种方法是从URL下载图像并从下载的文件构建URI。
如果您使用Glide从url加载图像，则可以通过以下方式完成：
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>
