有人对Stfalcon / ChatKit库有清晰的解释或教程吗？
我到目前为止所做的-
public void retrieveMessages() {
FirebaseFirestore db = FirebaseFirestore.getInstance();
final String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();
db.collection("Messages").whereEqualTo("UID", uid ).get().addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
@Override
public void onComplete(@NonNull Task<QuerySnapshot> task) {
if (task.isSuccessful()) {
for (QueryDocumentSnapshot document : task.getResult()) {
if (document != null) {
final String jobID = document.getString("JobID");
final String UserID = document.getString("UserID");
final String name = document.getString("Name");
final String company = document.getString("Company");
final String UID = document.getString("UID");
DatabaseReference mDatabase;
mDatabase = FirebaseDatabase.getInstance().getReference();
mDatabase.child(jobID).child(UserID).child("Messages").orderByKey().addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
fetchMessages((Map<String,Object>) dataSnapshot.getValue());
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
} else {
Log.d("LOGGER", "No such document");
}
}
}
}
});
}
private void fetchMessages(Map<String,Object> users) {
ArrayList<String> messages = new ArrayList<>();
//iterate through each user, ignoring their UID
for (Map.Entry<String, Object> entry : users.entrySet()){
//Get user map
Map singleUser = (Map) entry.getValue();
//Get phone field and append to list
messages.add((String) singleUser.get("MessageBody"));
}
messagesN = messages;
}
public Message getTextMessage() {
return getTextMessage(getRandomMessage());
}
public Message getTextMessage(String text) {
String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();
return new Message(getRandomid(),text, new Author(getRandomName(),uid));
}
static ArrayList<String> messagesN = new ArrayList<>();
static String getRandomMessage() {
return messagesN.toString();
}
static final ArrayList<String> idN = new ArrayList<String>() {
{
add("sdfdsfds");
add("sdfdsfdsf");
}
};
static String getRandomid() {
return idN.get(rnd.nextInt(idN.size()));
}
static final ArrayList<String> Name = new ArrayList<String>() {
{
add("sdfdsfds");
add("sdfdsfdsf");
}
};
static String getRandomName() {
return Name.get(rnd.nextInt(Name.size()));
}
public ArrayList<Message> getMessages(Date startDate) {
ArrayList<Message> messages = new ArrayList<>();
for (int i = 0; i < 10/*days count*/; i++) {
Message message;
message = getTextMessage();
Calendar calendar = Calendar.getInstance();
message.setCreatedAt(calendar.getTime());
messages.add(message);
}
return messages;
}
protected void loadMessages() {
new Handler().postDelayed(new Runnable() { //imitation of internet connection
@Override
public void run() {
ArrayList<Message> messages = getMessages(lastLoadedDate);
messagesAdapter.addToEnd(messages, false);
}
}, 1000);
}
}
但是问题是，我没有按预期从firebase提取消息， 而是将其显示为类似以下内容-[Hello，Hello，Hello]。如何正确实现此库？非常感谢您的帮助。
