我希望我的Firebase数据库使用用户个人资料图片图像URL进行初始化，我尝试添加此内容，但我的profileProfileUrl变量未使用ImageUri变量进行初始化？请帮助完成这件事...
我只希望第5个变量配置文件图像链接使用来自URI变量的图像URL字符串初始化，但未初始化
这是我的项目日志

您可以尝试以下方法：
private void uploadData() {
loadingBar.setTitle("Registering Retailer....");
loadingBar.setMessage("Please Wait While We Are Creating Retailer Database");
loadingBar.setCanceledOnTouchOutside(false);
loadingBar.show();
handleUpload(bitmap);
}
private void initializeUrl(Uri uri) {
profile_image_url = uri.toString();
//Initialize Firebase Database;
mDatabase = FirebaseDatabase.getInstance().getReference();
createUserDatabase(name, mobile, pass, spinner_port_place, profile_image_url);
}
首先上传个人资料图片，然后将用户保存到数据库。
您的代码不是这种情况。您将用户保存到数据库并传递到另一个屏幕，直到上传个人资料图片。
