在以下功能中，我正在从Firebase云数据库中检索用户信息（用户名和生物）。但是，日志显示没有此类文档，这意味着该文档不存在。在主要活动中，文档已成功上传到数据库。难道是在上载文档之前执行了检索用户信息功能？ 预先感谢！
以下代码来自SignupActivity：
private void retrieveProfileViaURLandUploadUserInfo (final String user, final String bioInfo) {
profileRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
pathToProfile = uri.toString();
String UID = getUserID();
UserInfo.put(USERNAME, user);
UserInfo.put(BIO, bioInfo);
UserInfo.put(PROFILE_URL, pathToProfile);
Log.d(TAG, "Got UID");
mDocRef.collection("users").document(UID).set(UserInfo)
.addOnSuccessListener(new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void aVoid) {
Log.d(USER_INFO, "Document has been saved");
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.w(USER_INFO, "Document was not saved!", e);
}
});
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception exception) {
Log.d(TAG, "retrieve profile image failure");
// pathToProfile = "uri download unsuccessful";
}
});
}
这在HomeActivity中
public void retrieveDisplayUserInfo() {
String UID = getUserID();
Log.d(TAG, UID);
mDocRef.collection("users").document(UID).get()
.addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
@Override
public void onComplete(@NonNull Task<DocumentSnapshot> task) {
if (task.isSuccessful()) {
DocumentSnapshot document = task.getResult();
if (document.exists()) {
Log.d(TAG, "DocumentSnapshot data: " + document.getData());
String userName = document.getString(USERNAME);
String shortBio = document.getString(BIO);
String URL = document.getString(PROFILE_URL);
displayUserName = findViewById(R.id.usernameView);
displayUserName.setText(userName);
displayBio = findViewById(R.id.shortBio);
displayBio.setText(shortBio);
} else {
Log.d(TAG, "No such document");
}
} else {
Log.d(TAG, "get failed with ", task.getException());
}
}
});
}
这是StackTrace
