捕获图库图像的方法

 fun openCamera() {
    try {
        val imageFile = createImageFile()
        val callCameraIntent =  Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        if(callCameraIntent.resolveActivity(activity.packageManager) != null) {
            val authorities = activity.packageName + ".fileprovider"
            this.imageUri = FileProvider.getUriForFile(context, authorities, imageFile)
            callCameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri)
            startActivityForResult(callCameraIntent, IMAGE_PICK_CODE)
        }
    } catch (e: IOException) {
        Toast.makeText(context, "Could not create file!", Toast.LENGTH_SHORT).show()
    }
}

onActivityResult

onActivityResult

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == IMAGE_PICK_CODE && resultCode == RESULT_OK) {


            try {

                //Getting the Bitmap from Gallery
                val bitmap = MediaStore.Images.Media.getBitmap(context.contentResolver, Uri.parse("file://"+this.imageUri!!)) as Bitmap
                this.imgThumb!!.setImageBitmap(bitmap)

            } catch (e:IOException) {
                e.printStackTrace()

        val imageFileName: String = "JPEG_" + timeStamp + "_"
        val storageDir: File = activity.getExternalFilesDir(Environment.DIRECTORY_PICTURES)
        if(!storageDir.exists()) storageDir.mkdirs()

推荐答案

如异常所示，该路径不存在！

As the exception indicates, The path does not exist!!

作为一些建议，请尽量避免与异常作斗争，即使您确定，也要遵循它们！

As a bit of advice, try not to fight with exceptions, Just follow them, even if you're pretty sure!

无论如何这次是

val authorities = activity.packageName + ".fileprovider"

值得指责，因为您已在清单中用.provider后缀定义了提供程序.

part to blame because you have defined the provider in manifest with .provider suffix.

因此更改为:

val authorities = activity.packageName + ".provider"

它应该通过更改而起作用.

It should be working by that change.

干杯！
