Question

我有两种用户类型。销毁应用程序后，我想要两个用户类型的两个活动。使用我的方法，我无法访问当前用户，因为用户未登录

auth = FirebaseAuth.getInstance();

  if (auth.getCurrentUser() != null) {

       if(loginflag.equals("0")){
            startActivity(new Intent(LoginActivity.this, HomeUsers.class));
            finish();
        }
        else if (loginflag.equals("1"))  {
            startActivity(new Intent(LoginActivity.this, HomeEducator.class));
            finish();
           }
        }
    }


private void loginControl() {

    FirebaseUser user = auth.getCurrentUser();
    String id = user.getUid();
    DatabaseReference FirebaseRef = FirebaseDatabase.getInstance().getReference().child("users").child(id);

    FirebaseRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot snapshot) {

            if(snapshot.exists()){
                loginflag = snapshot.child("flag").getValue().toString();
            }
        }
        @Override
        public void onCancelled(DatabaseError databaseError) {
        }
    });
}

Answer 1

要解决此问题，您需要在数据库中的每个用户下添加一个名为var的标记。然后，当用户登录时，检查用户是什么类型，以了解需要重定向的活动。逻辑应该如下：

userType
