android - 如何使用 parse.com android 获取当前用户信息

Question

我正在为 parse.com 开发安卓系统。我已成功登录并使用我的凭据注册，数据也正在上传到我的 parse.com 表中。登录代码段如下:

loginbutton.setOnClickListener(new OnClickListener() {

            public void onClick(View arg0) {
                // Retrieve the text entered from the EditText
                usernametxt = username.getText().toString();
                passwordtxt = password.getText().toString();

                // Send data to Parse.com for verification
                ParseUser.logInInBackground(usernametxt, passwordtxt,
                        new LogInCallback() {
                            public void done(ParseUser user, ParseException e) {
                                if (user != null) {
                                    // If user exist and authenticated, send user to Welcome.class
                                    Intent intent = new Intent(
                                            LoginSignupActivity.this,
                                            Welcome.class);
                                    startActivity(intent);
                                    Toast.makeText(getApplicationContext(),
                                            "Successfully Logged in",
                                            Toast.LENGTH_LONG).show();
                                    finish();
                                } else {
                                    Toast.makeText(
                                            getApplicationContext(),
                                            "No such user exist, please signup",
                                            Toast.LENGTH_LONG).show();
                                }
                            }
                        });
            }
        });

现在我需要获取当前用户的信息，请告诉我获取当前用户信息的方法或更改。

提前致谢!

调用 user.getObjectId(); 或 user.getString("username"); 是从 ParseObject 获取信息的方式。

loginbutton.setOnClickListener(new OnClickListener() {

            public void onClick(View arg0) {
                // Retrieve the text entered from the EditText
                usernametxt = username.getText().toString();
                passwordtxt = password.getText().toString();

                // Send data to Parse.com for verification
                ParseUser.logInInBackground(usernametxt, passwordtxt,
                        new LogInCallback() {
                            public void done(ParseUser user, ParseException e) {
                                if (user != null) {
                                    // If user exist and authenticated, send user to Welcome.class

                                    String username = user.getString("username");
                                    String userId = user.getObjectId();

                                    Intent intent = new Intent(
                                            LoginSignupActivity.this,
                                            Welcome.class);
                                    startActivity(intent);
                                    Toast.makeText(getApplicationContext(),
                                            "Successfully Logged in",
                                            Toast.LENGTH_LONG).show();
                                    finish();
                                } else {
                                    Toast.makeText(
                                            getApplicationContext(),
                                            "No such user exist, please signup",
                                            Toast.LENGTH_LONG).show();
                                }
                            }
                        });
            }
        });
