Kotlin:照相机只在模拟器(Android 8)上拍照，不正确地显示链接到实时存储数据库中的照片
Kotlin:照相机只在模拟器(Android 8)上拍照，不正确地显示链接到实时存储数据库中的照片
提问于 2022-03-20 18:06:24
我正在以instagram的形式编写一个应用程序(我学习YouTube的课程，他们在Android8上创建它，我试图在Android10上做同样的事情)，我只认识Kotlin几周了。已经实施了很多。但正是在火场中出现了问题。两个问题：
- 在应用程序中注册了一个用户，并将他的文本数据保存在firebase中--我可以从任何设备中这样做。通过Android 8上的仿真器-我可以拍摄一张照片，一切都正常工作，甚至链接，以改变个人资料照片是正确的显示。还有一个
ShareActivity文件，用户可以在“墙壁”上共享一张照片，问题是照片出现在google的存储中，而在实时数据库中，该照片的链接被写成"com.google.firebase.storage.UploadTask $TaskSnapshot@46529a6"，但应该以链接"https://firebasestorage.googleapis.com/v0/b/instapirate...的形式写成“，而配置文件照片是正确显示的，即:不，照片是不可见的。如何修复此缺陷?我从仿真器和数据库附加了一张照片：
。
- 还有另外一个问题，就是在Instagram仿真器中的安卓8上，我被要求获得相机的许可，我允许它和相机工作，拍照，一切都很好。而在android 10中，不请求对相机的许可，因此相机会打开，拍照，但不能保存照片(当我单击“保存”按钮时重新打开)。几次，如果我快速戳一下按钮--有时保存照片会有帮助，但这种情况在百万中有一种情况下会发生。这并不是因为相机的分辨率。我附上以下代码：
AndroidManifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.instapirate">
<uses-feature android:name="android.hardware.camera"

</application>
</manifest>配置文件是使用EditProfileActivity文件编辑的。下面有一段特定的代码，用于拍照和更改用户的化身，这里的链接工作，并以正常的形式加载到存储和RealtimeDatabase中，但是在Android 10上，照片也没有被拍摄，相机也被重置：
private lateinit var mUser: User
private lateinit var mFirebase: FirebaseHelper
private lateinit var mPendingUser: User
private lateinit var mCamera: CameraHelper
@SuppressLint("MissingSuperCall")
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode == mCamera.REQUEST_CODE && resultCode == RESULT_OK) {
mFirebase.uploadUserPhoto(mCamera.imageUri!!) {
mFirebase.storageUid().addOnCompleteListener {
val photoUrl = it.result.toString()
mFirebase.updateUserPhoto(photoUrl){
mUser = mUser.copy(photo = photoUrl)
profile_image.loadUserPhoto(mUser.photo)
}
}
}
}
}loadUserPhoto位于一个单独的utils文件中，其中存储了所有实用程序：
fun ImageView.loadUserPhoto(photoUrl: String?) =
ifNotDestroyed {
GlideApp.with(this).load(photoUrl).fallback(R.drawable.person).into(this)
}参与上述代码的远程类：CameraHelper
import android.app.Activity
import android.content.Intent
import android.net.Uri
import android.os.Environment
import android.provider.MediaStore
import androidx.core.content.FileProvider
import java.io.File
import java.text.SimpleDateFormat
import java.util.*
class CameraHelper(private val activity: Activity) {
var imageUri: Uri? = null
val REQUEST_CODE = 1
private val simpleDateFormat = SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US)
fun takeCameraPicture() {
val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
if (intent.resolveActivity(activity.packageManager) != null) {
val imageFile = createImageFile()
imageUri = FileProvider.getUriForFile(activity,
"com.example.instapirate.fileprovider",
imageFile)
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri)
activity.startActivityForResult(intent, REQUEST_CODE)
}
}
private fun createImageFile(): File {
val storageDir = activity.getExternalFilesDir(Environment.DIRECTORY_PICTURES)
return File.createTempFile(
"JPEG_${simpleDateFormat.format(Date())}_",
".jpg",
storageDir
)
}
}FirebaseHelper
import android.app.Activity
import android.net.Uri
import com.example.instapirate.activities.showToast
import com.google.firebase.auth.AuthCredential
import com.google.firebase.auth.FirebaseAuth
import com.google.firebase.database.DatabaseReference
import com.google.firebase.database.FirebaseDatabase
import com.google.firebase.storage.FirebaseStorage
import com.google.firebase.storage.StorageReference
import com.google.firebase.storage.UploadTask
class FirebaseHelper(private val activity: Activity) {
val auth: FirebaseAuth = FirebaseAuth.getInstance()
val database: DatabaseReference = FirebaseDatabase.getInstance().reference
val storage: StorageReference = FirebaseStorage.getInstance().reference
fun storageUid() = storage.child("users/${auth.currentUser!!.uid}/photo/").downloadUrl
fun uploadUserPhoto(photo: Uri, onSuccess: (UploadTask.TaskSnapshot) -> Unit) {
storage.child("users/${currentUid()!!}/photo").putFile(photo)
.addOnCompleteListener {
if (it.isSuccessful) {
onSuccess(it.result!!)
} else {
activity.showToast(it.exception!!.message!!)
}
}
}
fun updateUserPhoto(photoUrl: String, onSuccess: () -> Unit) {
database.child("users/${currentUid()!!}/photo").setValue(photoUrl)
.addOnCompleteListener {
if (it.isSuccessful) {
onSuccess()
} else {
activity.showToast(it.exception!!.message!!)
}
}
}
fun updateUser(updates: Map<String, Any?>, onSuccess: () -> Unit) {
database.child("users").child(currentUid()!!).updateChildren(updates)
.addOnCompleteListener {
if (it.isSuccessful) {
onSuccess()
} else {
activity.showToast(it.exception!!.message!!)
}
}
}
fun updateEmail(email: String, onSuccess: () -> Unit) {
auth.currentUser!!.updateEmail(email).addOnCompleteListener {
if (it.isSuccessful) {
onSuccess()
} else {
activity.showToast(it.exception!!.message!!)
}
}
}
fun reauthenticate(credential: AuthCredential, onSuccess: () -> Unit) {
auth.currentUser!!.reauthenticate(credential).addOnCompleteListener {
if (it.isSuccessful) {
onSuccess()
} else {
activity.showToast(it.exception!!.message!!)
}
}
}
fun currentUserReference(): DatabaseReference =
database.child("users").child(currentUid()!!)
fun currentUid(): String? =
auth.currentUser?.uid
}还有一个实现将照片上传到提要的ShareActivity文件，这就是Firebase出现问题的地方，因为链接是在这里以不正确的形式显示的(提要的屏幕截图在上面)。如果照片是通过仿真器在Android 8上拍摄的，就会发生这种情况。(在Android 10手机上，保存照片后，相机重新打开，我不得不再拍一次照片，等等。)
class ShareActivity : BaseActivity(2) {

})
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

if (requestCode == mCamera.REQUEST_CODE) {
if (resultCode == RESULT_OK) {
GlideApp.with(this).load(mCamera.imageUri).centerCrop().into(post_image)
} else {
finish()
}
}
}
private fun share() {
val imageUri = mCamera. imageUri
if (imageUri != null) {
val uid = mFirebase.currentUid()!!
mFirebase.storage.child("users").child(uid).child("images")
.child(imageUri.lastPathSegment.toString()).putFile(imageUri).addOnCompleteListener{
if (it.isSuccessful){

mFirebase.database.child("images").child(uid).push()

.addOnCompleteListener {

finish()
}
}
} else {
showToast(it.exception!!.message!!)
}
}
} else {
showToast(it.exception!!.message!!)
}
}
}
}
private fun mkFeedPost(uid: String, imageDownloadUrl: String): FeedPost {
return FeedPost(

}
}当试图在android 10上保存照片时，以下文本出现在Debug中(由于限制而无法显示整个错误，但我认为这是错误的一个重要部分)：

刚将以下代码添加到FirebaseHelper中：
fun uploadSharePhoto(localPhotoUrl: Uri, onSuccess: (UploadTask.TaskSnapshot) -> Unit) =
storage.child("users/${auth.currentUser!!.uid}").child("images")
.child(localPhotoUrl.lastPathSegment!!)
.putFile(localPhotoUrl)
.addOnCompleteListener {
if (it.isSuccessful)
onSuccess(it.result!!)
else
activity.showToast(it.exception!!.message!!)
}
fun addSharePhoto(globalPhotoUrl: String, onSuccess: () -> Unit) =
database.child("images").child(auth.currentUser!!.uid)
.push().setValue(globalPhotoUrl)
.addOnComplete { onSuccess() }
private fun Task<Void>.addOnComplete(onSuccess: () -> Unit) {
addOnCompleteListener {
if (it.isSuccessful)
onSuccess()
else
activity.showToast(it.exception!!.message!!)
}
}在ShareActivity中，编辑了share()函数：
private fun share() {
val imageUri = mCamera.imageUri
if (imageUri != null) {
mFirebase.uploadSharePhoto(imageUri) {
it.metadata!!.reference!!.downloadUrl.addOnSuccessListener {
mFirebase.addSharePhoto(it.toString()) {
mFirebase.database.child("feed-posts").child(mFirebase.auth.currentUser!!.uid)
.push()
.setValue(mkFeedPost(mFirebase.auth.currentUser!!.uid, it.toString()))
.addOnCompleteListener {
if (it.isSuccessful) {
startActivity(Intent(this,
ProfileActivity::class.java))
finish()
}
}
}
}
}
}
}现在所有的链接都是正确的
