java - 当用户创建帐户时，它会进入家庭活动而不是登录活动，如何避免这种情况？

Question

当用户单击创建帐户时，任务完成后它应该转到登录活动，但相反，它直接将其带到家庭活动（不要求登录凭据）。

我写在登录活动的意图名称中（在创建帐户按钮中）

（如果需要该信息，我还编写了检查用户是否在登录活动中登录的代码）

以下是创建帐户按钮中的代码：

cma.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                //getting the data
                username= nun.getText().toString().trim();
                status= sta.getText().toString().trim();
                emailid= ei.getText().toString().trim();
                courses= cou.getText().toString().trim();
                year = yr.getSelectedItem().toString();
                dateofbirth= dob.getText().toString().trim();
                collegeid= cid.getText().toString().trim();
                password= pw1.getText().toString().trim();
                cpass= pw2.getText().toString().trim();
                int selectedId = gender.getCheckedRadioButtonId();
                sexgender = (RadioButton) findViewById(selectedId);
                final String gender = sexgender.getText().toString().trim();

                if (circularImageView.getDrawable() != null) {
                    cma.setText("Creating Fresh Account....");
                    createAccProgress.setVisibility(View.VISIBLE);
                    //get image from imageview
                    Bitmap bitmap = ((BitmapDrawable) circularImageView.getDrawable()).getBitmap();
                    ByteArrayOutputStream baos = new ByteArrayOutputStream();
                    //image compress
                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
                    data = baos.toByteArray();
                    String filePathAndName="ProfilePictures/"+"profile_"+ emailid;

                    StorageReference ref = FirebaseStorage.getInstance().getReference().child(filePathAndName);
                    ref.putBytes(data)
                            //ERROR on Line Below
                            .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                                @Override
                                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                                    //Success to firebase storage
                                    Task<Uri> uriTask = taskSnapshot.getStorage().getDownloadUrl();
                                    while (!uriTask.isSuccessful());
                                    downloadUri = uriTask.getResult().toString();

                                    if (uriTask.isSuccessful()) {
                                        mauth.createUserWithEmailAndPassword(emailid,cpass).addOnCompleteListener(new OnCompleteListener<AuthResult>() {

根据文件：

如果创建了新帐户，则用户也已登录。在回调中，您可以使用 getCurrentUser 方法获取用户的帐户数据。

因此，当您在成功创建帐户后在登录活动中检查用户是否登录时，它会找到已登录的用户并继续进行主页活动。
