My Realm不会将新数据更新到realm数据库

Question

我正在尝试将数据更新到数据库，但没有任何反应。

当Setting.java为onPause（）时，数据将更新

Setting.java是Setting.java的一部分

@Override
public void onPause(){
    RealmUpdate realmUpdate = new RealmUpdate();
    realmUpdate.upsertUserProfile( application.getEmail(),
            textView_fname.getText().toString(), textView_lname.getText().toString(),
            textView_gender.getText().toString(), textView_birthdate.getText().toString(),
            "074123456");

    Log.d(getClass().getSimpleName(), "Prepare to caretaker Profile");
    realmUpdate.upsertCaretakerProfile( application.getEmail(),
            textView_carefname.getText().toString(), textView_carelname.getText().toString(),
            textView_careemail.getText().toString(), textView_caretel.getText().toString());

    startActivity( new Intent( context, MainActivity.class) );
    super.onPause();
}

我已经检查过所有textView都可以获得价值。所以问题可能出在我的RealmUpdate类中。

realm update.Java

public class RealmUpdate {

private Realm realm;

/**
 *
 * @param email Email of User that use in this application.
 * @param fname First Name of User
 * @param lname Last Name of User
 * @param gender Gender of User
 * @param birthdate Birth Date of User
 * @param tel Telephone Number of User

public void upsertUserProfile( final String email, final String fname, final String lname,
                               final String gender, final String birthdate, final String tel){
    realm = Realm.getDefaultInstance();
    realm.executeTransactionAsync(new Realm.Transaction() {
        @Override
        public void execute(@NonNull Realm realm){
            try{
                SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
                String[] arr_date = birthdate.split("/");
                String real_date = arr_date[2] + "-" + arr_date[1] + "-" + arr_date[0];
                Date date = format.parse(real_date);

                UserProfile data = realm.where(UserProfile.class)
                        .equalTo("Email", email)
                        .findFirst();

                exception.printStackTrace();
            }
        }
    }, new Realm.Transaction.OnSuccess() {
        @Override

    });
    if (!realm.isClosed())
        realm.close();
}

public void upsertCaretakerProfile( final String email, final String cfname, final String clname
            , final String cemail, final String ctel){

        }
    });
    if ( !realm.isClosed())
        realm.close();
    }
}

我的问题是方法upsertProfile可以更新数据，但upsertCaretakerProfile不能。 logcat也没有错误。

Answer 1

很抱歉这是一个无意义的问题。现在我发现了我的错误，我的错误在于我没有发布的初始方法。

public void initialValue(){
    RealmSearch search = new RealmSearch();
    UserProfile profile = search.searchUserProfile(application.getEmail());
    Log.d(getClass().getSimpleName(), application.getEmail());
    textView_fname.setText( profile.getFName());
    textView_lname.setText( profile.getLName());
    textView_birthdate.setText( (new SimpleDateFormat("dd/MM/yyyy")).format( profile.getBirthdate()) );
    textView_gender.setText( profile.getGender());
    textView_tel.setText( profile.getTel());

    CaretakerProfile cprofile = search.searchCaretakerProfile(application.getEmail());
    textView_carefname.setText( cprofile.getcFName());
    textView_carelname.setText( cprofile.getcLName());
    textView_careemail.setText( cprofile.getcEmail());
    textView_caretel.setText( cprofile.getcTel());
}

在编辑我的代码之前，我初始使用其类的Object进行cprofile，因此它具有空值，因为cprofile不会从数据库中查询数据。

CaretakerProfile cprofile = new CaretakerProfile()

最后，我将标记这篇文章，因为这是一个无意义的问题。
