我的答案与@Macarse 解决方案几乎相同,但我还添加了一个额外的意图来显示画廊应用程序(例如:Google 照片),并且是用 Kotlin 编写的:
val REQUEST_CODE_GET_IMAGE = 101
private fun addProfileImage() {
val pickImageFileIntent = Intent()
pickImageFileIntent.type = "image/*"
pickImageFileIntent.action = Intent.ACTION_GET_CONTENT
val pickGalleryImageIntent = Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
val captureCameraImageIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
val pickTitle = "Capture from camera or Select from gallery the Profile photo"
val chooserIntent = Intent.createChooser(pickImageFileIntent, pickTitle)
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arrayOf(captureCameraImageIntent, pickGalleryImageIntent))
startActivityForResult(chooserIntent, REQUEST_CODE_GET_IMAGE)
}
从结果意图中提取图像:
private var imageTempFile: File? = null
private var imageMimeType: String? = null
private fun extractImage(intent: Intent?) {
val imageUri = intent?.data
imageUri?.let {
Glide.with(this)
.load(imageUri)
.into(profileImageCiv)
imageTempFile = MediaUtils.copyContentFromUriToCacheFile(this, imageUri, Settings.DIRECTORY_CACHE_TEMP_PROFILE_IMAGE)
imageMimeType = MediaUtils.getMimeType(this, imageUri)
} ?: run {
intent?.extras?.get("data")?.let { bitmap -> // Bitmap was returned as raw bitmap
Glide.with(this)
.load(bitmap)
.into(profileImageCiv)
imageTempFile = MediaUtils.writeBitmapToCacheFile(this, bitmap as Bitmap, Settings.DIRECTORY_CACHE_TEMP_PROFILE_IMAGE)
imageMimeType = "image/jpeg" // The bitmap was compressed as JPEG format. The bitmap itself doesn't have any format associated to it
} ?: run {
imageTempFile = null
imageMimeType = null
Log.e("Intent data is null.")
Log.d("Error during photo selection")
}
}
}
