搜索了 2-3 天并尝试了不同的解决方案后，我不知道问题出在哪里。图片已加载，一切正常，但实时它不想以任何方式保存，我已经很困惑在哪里使用 getDownloadUrl 形成，因为对 ref 的调用和对 task/uploadtask 的调用都必须返回正确的值。我什至已经删除了 UploadImage 中的所有进度阅读器代码，现在有来自 firebase 文档的代码。
private void uploadImage() {
StorageReference storage = FirebaseStorage.getInstance().getReference("Users/" + user.getUid());
StorageReference fileRef = storage.child("ava" + UUID.randomUUID().toString());
UploadTask uploadTask = fileRef.putFile(filePath);
Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
@Override
public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
if (!task.isSuccessful()) {
Toast.makeText(ProfileEdit.this, "err1 = " + newphotoUri.toString(), Toast.LENGTH_SHORT).show();
throw task.getException();
}
Toast.makeText(ProfileEdit.this, "253 = " + newphotoUri.toString(), Toast.LENGTH_SHORT).show();
// Continue with the task to get the download URL
return fileRef.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
newphotoUri = task.getResult();
Toast.makeText(ProfileEdit.this, "uri = " + newphotoUri.toString(), Toast.LENGTH_LONG).show();
} else {
Toast.makeText(ProfileEdit.this, "err2 = " + newphotoUri.toString(), Toast.LENGTH_SHORT).show();
// Handle failures
// ...
}
}
});
/* if (filePath != null) {
UploadTask uploadTask = fileRef.putFile(filePath);
uploadTask.addOnFailureListener(new OnFailureListener() {
@Override

//ошибка загрузки

uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {

}答案 0 :(得分：0)
感谢您的提示。 决定如下。我想通过点击用户信息中的一个按钮来保存uri，但是这导致了一个错误，因为用户总是放不了图片，有时uri返回null，因为文件没有时间加载，链接是没有及时形成。然后我想起点击一个按钮就已经调用了加载图片，我只是在照片上传块中写下了指向图片的链接。嗯，总之，这里，甚至收紧
uploadTask.continueWithTask(...).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult(); //isRef it`s FirebaseReference
isRef.child("Users").child(userID).child("photoAva").setValue("url", downloadUri.toString());
Toast.makeText(ProfileEdit.this, "Updated", Toast.LENGTH_SHORT).show();
} else {
//Toast.makeText(mContext, "Failed", Toast.LENGTH_SHORT).show();
// Handle failures
// ...
}
}
});omg，我花了 3 天时间才弄明白......
