我有newEventActivity，用户可以在其中创建新事件，然后用户选择图像，然后输入事件的描述。我确信我的代码会被执行，因为对task.isSuccessful的Intent将我转发到Menu.class。但是，eventsMap不会存储在Firebase存储上。
我没有收到任何错误，所以我不确定如何解决此问题。
我也无法将图像存储在存储中，也无法将Map <>存储在Firestore中，因此基本上我的整个方法都行不通。
newEventButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
final String desc = newEventDesc.getText().toString();
if(!TextUtils.isEmpty(desc) && eventImageUri != null){
newEventProgress.setVisibility(View.VISIBLE);
String imageUUID = UUID.randomUUID().toString();
final StorageReference file = storageReference.child("event_images").child(imageUUID + ".jpg");
file.putFile(eventImageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
@Override
public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {
if(task.isSuccessful()){
String downloadUri = file.getDownloadUrl().toString();
Map<String, Object> eventsMap = new HashMap<>();
eventsMap.put("image_url", downloadUri);
eventsMap.put("desc", desc);
firebaseFirestore.collection("Events").add(eventsMap).addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
@Override
public void onComplete(@NonNull Task<DocumentReference> task) {
if(task.isSuccessful()){
Toast.makeText(newEventActivity.this, "Event Was Created", Toast.LENGTH_LONG).show();
Intent intent = new Intent(newEventActivity.this, Menu.class);
startActivity(intent);
finish();
} else {
String error = task.getException().getMessage();
Toast.makeText(newEventActivity.this, error , Toast.LENGTH_LONG).show();
}
newEventProgress.setVisibility(View.INVISIBLE);
}
});
} else{
newEventProgress.setVisibility(View.INVISIBLE);
}

}
}
});
