保存后不显示个人资料图像（它只显示空白屏幕）答案

【问题标题】：Profile image not showing after saving(it just shows blank white screen)保存后不显示个人资料图像（它只显示空白屏幕）
【发布时间】：2019-06-27 22:49:16
【问题描述】：

我正在尝试上传用户个人资料图片并存储在 firebase 中。我的图片已成功存储在 firebase 存储和用户数据库中。

当我上传图像时它显示在我的屏幕上，但是一旦我保存并重新打开设置以查看个人资料图像，它不显示，它只是显示空白的白屏（但重新打开时显示姓名和电话，仅图片不显示）

我附加了从 db 获取值并在 ui 中显示的代码，还添加了 saveUserInformation()，当用户单击保存图像按钮时调用该函数，此函数将名称、电话和 profileimage 保存在 db 中。我在下面添加了数据库的屏幕截图，还添加了我遇到的错误的 sn-p。

我做错了什么？

这是我控制台记录时 glide 输出的内容： profile img here：目标：android.support.v7.widget.AppCompatImageView{528bbb2 V.ED..C........ID 0,0-300,300 #7f0a00b9 app:id/profileImage}[CDS]rx超时：0

【问题讨论】：

请同时添加用于将profileImageUrl 添加到数据库的代码。
我已经更新了问题并添加了用于将 profileImageUrl 添加到数据库的代码

标签： android firebase android-studio firebase-realtime-database kotlin

【解决方案1】：

您收到以下错误：

com.google.android.gms.tasks.zzu@c0645c1 加载失败

因为您正在尝试显示不存在的图像。正如我在您的数据库中看到的，profileImageUrl 属性包含一个无效有效的图像 url。

看到红线了吗？它实际保存的是内存中对象的地址，不是图像 url。发生这种情况是因为您在 downloadUrl 对象上调用 toString() 方法。因此，您获取下载网址的方式不正确。 This 是获取网址的正确方法。一旦你得到图像的 url 并将其添加到数据库中，一切都会按预期工作。

【讨论】：

我按照你说的修改了我的代码，是下载地址的问题，现在可以了。非常感谢。

【解决方案2】：

我也遇到了这个问题，解决方法如下

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

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

【讨论】：

我尝试添加 requestoptions，但它不起作用，我仍然看不到任何图像，并且遇到了与我在上面添加的问题相同的错误。

【解决方案3】：

这是我更新 imagePath 监听器代码的函数，现在可以正常工作-

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()
            })
