Question

我正在使用android for parse.com。我已成功登录并注册了我的凭据，数据也在我的parse.com表中上传。登录的代码段如下：

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，请提及方法或更改我必须做的以获取当前用户的信息。

提前致谢！

Answer 1

调用user.getObjectId();或user.getString("username");之类的内容是从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();
                                }
                            }
                        });
            }
        });

用户通过身份验证后，打开新活动，然后使用静态方法getCurrentUser访问当前用户。

ParseUser currentUser = ParseUser.getCurrentUser();
if (currentUser != null) {
  // do stuff with the user
} else {
  // show the signup or login screen
}

Answer 3

有了这个，我得到了用户信息。

ParseUser currentUser = ParseUser.getCurrentUser();
if (currentUser != null){
   String email = currentUser.getEmail();
   String username = currentUser.getUsername();
   String objectID = currentUser.getObjectId();
} else {
  Toast.makeText(getApplicationContext(), "the user does not exist!",Toast.LENGTH_SHORT).show();
}

Answer 4

ParseUser currentUser = ParseUser.getCurrentUser();
            currentUser.getUsername();
            newTable.put("user_name",currentUser );

这是您在其他表（newTable）中获取用户信息的方法。如果有帮助，请告诉我。：）

Answer 5

ParseUser currentUser = ParseUser.getCurrentUser();
String currentUserString = String.valueOf(currentUser.getUsername());
newTable.put("user_name",currentUserString);

由于某些原因我不确定，你需要将currentUser转换为String。
