java - 如何从一个 fragment 获取值并将其传递给另一个 fragment

Question

我有两个 fragment ，一个是 fragment X ，一个是 fragment y。 fragment X 用于使用 Web 服务的注册过程。我想将(电子邮件、手机)相同的值从 fragment X 传递到 fragment Y。

这是我的代码:

fragment x:

Signup.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    String sName = Name.getText().toString();
                    String sPhoneNo = Phone.getText().toString();
                    String sEmailId = EmailId.getText().toString();



                    // Instantiate Http Request Param Object
                    RequestParams params = new RequestParams();

                    if (Utility.isNotNull(sName) && Utility.isNotNull(sPhoneNo) && Utility.isNotNull(sEmailId) ) {
                        if (Utility.line2_validate(sName)) {
                            if (Utility.validate(sPhoneNo)) {
                                if (Utility.email_validate(sEmailId)) {

                                   //Get value from this Fragment 
                                    FragmentY pf = new FragmentY ();
                                    Bundle args = new Bundle();
                                    args.putString("mobile", sPhoneNo);
                                    args.putString("email",sEmailId);
                                    pf.setArguments(args);

                                    //Inflate the fragment
                                    getFragmentManager().beginTransaction().add(R.id.passwordLayout, pf).commit();

                                    // Put Http parameter username with value of Name Edit View control
                                    params.put("name", sName);
                                    // Put Http parameter email with value of Email Edit Value control
                                    params.put("email", sEmailId);
                                    // Put Http parameter mobile with value of Mobile Edit Value control
                                    params.put("mobile", sPhoneNo);
                                    // Invoke Signup RESTful Web Service with Http parameters
                                    signUpWS(params);

                                    //Toast.makeText(getActivity().getApplicationContext(), "Success", Toast.LENGTH_SHORT).show();
                                    //((MainActivity) getActivity()).navigatetoPasswordActivity();

                                }
                                else {
                                    EmailId.setError("Enter valid Email");
                                }

                            }
                            else {
                                Phone.setError("Enter valid Mobile");
                            }

                        }
                        else {
                            Name.setError("Enter valid Name");
                        }

                    }
                    else {
                        Toast.makeText(getActivity().getApplicationContext(), "Please fill the form, don't leave any field blank", Toast.LENGTH_SHORT).show();
                    }
                }



            });

fragment Y:

//  Retrive the value from fragment x
String strMobile = getArguments().getString("mobile");
                String strEmail = getArguments().getString("email");

请任何人帮助我..

提前致谢!

您可以通过在fragment中创建构造函数将值传递给fargment

例如，

对于 fragment x 在构造函数中传递值

PasswordFragment pf = new PasswordFragment (name, email, mobile);

对于fragmnet y，您可以从此构造函数检索值

String name, email, mobile
public PasswordFragment(String name, String email, String mobile) {
        // TODO Auto-generated constructor stub
        this.name=name;
        this.email=email;
        this.mobile=mobile;
}
