Question

这是我的代码，我不知道如何转换Funciont而不是Func1 请帮我！！！谢谢！

问题出在： - ＆gt; .map（new Func1，Integer＆gt;（）{

我无法解决这个问题，这是解决方案吗？我发现2.0中有什么不同但我没有解决问题。

public class LiveAccountServices {

    private static LiveAccountServices mLiveAccountServices;

    public static LiveAccountServices getInstance(){

        if(mLiveAccountServices == null){
            mLiveAccountServices = new LiveAccountServices();
        }
        return  mLiveAccountServices;
    }`enter code here`

    public Subscription sendRegistrationInfo(EditText userNameEt, EditText userEmailEt,
                                             EditText userPasswordEt, Socket socket){

        List<String> userDetails = new ArrayList<>();
        userDetails.add(userNameEt.getText().toString());
        userDetails.add(userEmailEt.getText().toString());
        userDetails.add(userPasswordEt.getText().toString());

        Observable userDetailsObservable = Observable.just(userDetails);

        return userDetailsObservable
                .subscribeOn(Schedulers.io())
                .map(new Func1<List<String>, Integer>(){
                    @Override
                    public Integer call (List<String> strings){
                        return  null;
                    }
                });

}

我想使用这个导入而不是rx.Observable和其他rx.somethings现在代码已经完成......

//import io.reactivex.functions.Function;

//import io.reactivex.schedulers.Schedulers;
//import io.reactivex.android.schedulers.AndroidSchedulers;
public class LiveAccountServices {

    private static LiveAccountServices mLiveAccountServices;

    private final int USER_ERROR_EMPTY_PASSWORD =1;
    private final int USER_ERROR_EMPTY_EMAIL=2;
    private final int USER_ERROR_EMPTY_USERNAME =3;
    private final int USER_ERROR_PASSWORD_SHORT =4;
    private final int USER_ERROR_EMAIL_BAD_FORMAT =5;

    private final int SERVER_SUCCESS =6;
    private final int SERVER_FAILURE =7;


    public static LiveAccountServices getInstance(){

        if(mLiveAccountServices == null){
            mLiveAccountServices = new LiveAccountServices();
        }
        return  mLiveAccountServices;
    }



    public Subscription sendRegistrationInfo(final EditText userNameEt, final EditText userEmailEt,
                                             final EditText userPasswordEt, final Socket socket) {

        List<String> userDetails = new ArrayList<>();
        userDetails.add(userNameEt.getText().toString());
        userDetails.add(userEmailEt.getText().toString());
        userDetails.add(userPasswordEt.getText().toString());

        Observable<List<String>> userDetailsObservable = Observable.just(userDetails);

        return userDetailsObservable

                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<Integer>() {
                    @Override
                    public void onCompleted() {

                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onNext(Integer integer) {
                        if(integer.equals(USER_ERROR_EMPTY_EMAIL)){
                            userEmailEt.setError("Email Address Can't Be Empty");
                        } else if (integer.equals(USER_ERROR_EMAIL_BAD_FORMAT)){
                            userEmailEt.setError("Please check your email format");
                        } else if (integer.equals(USER_ERROR_EMPTY_PASSWORD)){
                            userPasswordEt.setError("Password Can't Be Blank");
                        } else if (integer.equals(USER_ERROR_EMPTY_PASSWORD)){
                            userPasswordEt.setError("Password Must Be At Least 6 Characters Long");
                        } else if (integer.equals(USER_ERROR_EMPTY_USERNAME)){
                            userNameEt.setError("Username Can't Be Empty");

                    }
                });

    }

    private boolean isEmailValid(CharSequence email){
        return Patterns.EMAIL_ADDRESS.matcher(email).matches();
    }

}
