保存后不顯示個人資料圖像（它只顯示空白屏幕）

Question

我正在嘗試上傳用戶個人資料圖像並存儲在 firebase 中。我的圖像成功存儲在 firebase 存儲和用戶數據庫中。

當我上傳圖像時，它顯示在我的屏幕上，但是一旦我保存並重新打開設置以查看個人資料圖像，它就不會顯示，它只會顯示空白的白屏（但重新打開時會顯示姓名和電話，只有圖像不會顯示）展示）

我附上了從 db 獲取值並在 ui 中顯示的代碼，還添加了 saveUserInformation()，當用戶單擊保存圖像按鈕時調用該代碼，此函數將姓名、電話和個人資料圖像保存在 db 中。 我在下面添加了數據庫的屏幕截圖，並添加了我得到的錯誤片段。

我究竟做錯了什么？

Answer 1

我也有這個問題，解決了如下問題

RequestOptions options = new RequestOptions()
       .fitCenter()
       .error(errorImageDrawble)
       .diskCacheStrategy(DiskCacheStrategy.ALL)
       .priority(priority.HIGH);

Glide
     .with(applicationContext)
     .load(mProfileImageUrl)
     .apply(options)
     .into(mProfileImage);

Answer 2

您收到以下錯誤：

com.google.android.gms.tasks.zzu@c0645c1 加載失敗

因為您正在嘗試顯示不存在的圖像。 正如我在你的數據庫中看到， profileImageUrl屬性包含一個圖像URL無效。

看到紅線了嗎？ 它實際保存的是內存中對象的地址，而不是圖像 url。 發生這種情況是因為您正在對downloadUrl對象調用toString()方法。 所以你獲取下載 url 的方式是不正確的。 這是獲取 url 的正確方法。 獲得圖像的 url 並將其添加到數據庫后，一切都會按預期工作。

Answer 3

這是我更新 imagePath 偵聽器代碼的函數，現在可以正常工作了-

 private fun saveUserInformation(){ mName=mNameField.text.toString() mPhone=mPhoneField.text.toString() val userInfo=HashMap<String,Any>() userInfo.put("name",mName) userInfo.put("phone",mPhone) mCustomerDatabase.updateChildren(userInfo) if(resultUri!=null){ val imagePath:StorageReference=mStorage.child("customer_profile_image").child(userId).child(resultUri.lastPathSegment ) val uploadTask:UploadTask=imagePath.putFile(resultUri) uploadTask.addOnSuccessListener(OnSuccessListener <UploadTask.TaskSnapshot>(){taskSnapshot-> //*********************This is the upadated part of code imagePath.downloadUrl.addOnSuccessListener(OnSuccessListener<Uri>{resultUri-> val downloadUrl=resultUri.toString() val newImage= HashMap<String,Any>() newImage["profileImageUrl"] = downloadUrl mCustomerDatabase.updateChildren(newImage) }).addOnFailureListener(OnFailureListener() { Toast.makeText(this,"Profile image not",Toast.LENGTH_SHORT).show() }) //******************************************************************************* }).addOnFailureListener(OnFailureListener() { Toast.makeText(this,"Profile image not uploaded",Toast.LENGTH_SHORT).show() }) } finish() }
