我试图使用 Android 设备中预装的本机相机应用程序来为我的应用程序捕获图像。为此，我一直在使用这段代码：

当用户点击按钮时调用一个函数

take_img_btn.setOnClickListener {
    dispatchTakePictureIntent()
}

该函数应该执行以下操作：

    private fun dispatchTakePictureIntent() {
        Intent(MediaStore.ACTION_IMAGE_CAPTURE).also { takePictureIntent ->

                    createImageFile()
                } catch (ex: IOException) {
                    // Error occurred while creating the File
                    ex.printStackTrace()
                    null
                }
                // Continue only if the File was successfully created
                photoFile?.also {
                    val photoURI: Uri = FileProvider.getUriForFile(
                        this,
                        "com.example.android.fileprovider",
                        it …
