如何将Facebook用户的数据传输到Parse.com?我将在下面提供的代码构成一个用户,但是当我登录时它没有用数据更新它,为什么它不起作用?
public class LoginActivity extends Activity {
private EditText usernameView;
private EditText passwordView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
LoginButton loginButton = (LoginButton)findViewById(R.id.login_button);
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onLoginButtonClicked();
}
});
// Set up the login form.
usernameView = (EditText) findViewById(R.id.etUsername);
passwordView = (EditText) findViewById(R.id.etPassword);
// Set up the submit button click handler
findViewById(R.id.ibLogin).setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
onNormalLoginButton();
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
ParseFacebookUtils.onActivityResult(requestCode, resultCode, data);
}
private void onNormalLoginButton(){
// Validate the log in data
boolean validationError = false;
StringBuilder validationErrorMessage =
new StringBuilder(getResources().getString(R.string.error_intro)); //please
if (isEmpty(usernameView)) {
validationError = true;
validationErrorMessage.append(getResources().getString(R.string.error_blank_username));//enter username
}
if (isEmpty(passwordView)) {
if (validationError) {
validationErrorMessage.append(getResources().getString(R.string.error_join));// and
}
validationError = true;
validationErrorMessage.append(getResources().getString(R.string.error_blank_password));//enter password
}
validationErrorMessage.append(getResources().getString(R.string.error_end));// .
// If there is a validation error, display the error
if (validationError) {
Toast.makeText(LoginActivity.this, validationErrorMessage.toString(), Toast.LENGTH_LONG) //LENGHT_LONG means how long the message will stand
.show();
return;
}
// Set up a progress dialog
final ProgressDialog dlg = new ProgressDialog(LoginActivity.this);
dlg.setTitle("Please wait.");
dlg.setMessage("Logging in. Please wait.");
dlg.show();
// Call the Parse login method
ParseUser.logInInBackground(usernameView.getText().toString(), passwordView.getText()
.toString(), new LogInCallback() {
public void done(ParseUser user, ParseException e) {
dlg.dismiss();
if (e != null) {
// Show the error message
Toast.makeText(LoginActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
} else {
// Start an intent for the dispatch activity
ParseUser userguy=ParseUser.getCurrentUser();
boolean validated=userguy.getBoolean("emailVerified");
if(validated)
{
ParseInstallation installation = ParseInstallation.getCurrentInstallation();
installation.put("user", userguy.getObjectId());
installation.put("fullname",userguy.getString("fullname"));
installation.saveInBackground();
openMainActivity();
}else{
Toast.makeText(LoginActivity.this, "You need to confirm your Email!",Toast.LENGTH_LONG).show();
}
}
}
});
}
private void onLoginButtonClicked() {
List<String> permissions = Arrays.asList("email", "user_about_me");
ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() {
@Override
public void done(ParseUser user, ParseException err) {
if (user == null) {
Log.d("MyApp", "Uh oh. The user cancelled the Facebook login.");
} else if (user.isNew()) {
Profile profile = Profile.getCurrentProfile();
user.put("gender", "");
user.put("location", "");
user.put("age", "");
user.put("meet", "");
user.put("status", "");
user.put("link", "");
user.put("fullname", profile.getName());
user.setEmail("");
user.signUpInBackground();
ParseInstallation installation = ParseInstallation.getCurrentInstallation();
installation.put("user", user.getObjectId());
installation.put("fullname", user.getString("fullname"));
installation.saveInBackground();
openMainActivity();
} else {
Log.d("MyApp", "User logged in through Facebook!");
ParseInstallation installation = ParseInstallation.getCurrentInstallation();
installation.put("user", user.getObjectId());
installation.put("fullname", user.getString("fullname"));
installation.saveInBackground();
openMainActivity();
}
}
});
}
private void openMainActivity(){
Intent intent = new Intent(LoginActivity.this, DispatchActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
private boolean isEmpty(EditText etText) {
if (etText.getText().toString().trim().length() > 0) {
return false;
} else {
return true;
}
}
public void signUp(View view) {
Intent intent = new Intent(LoginActivity.this, RegisterActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
忽略onNormalLoginButton()
它有效,onloginButtonClicked()
就是问题。
编辑: 我试过了这个,但它也没有用。
user.saveInBackground(new SaveCallback() {
@Override
public void done(ParseException e) {
if(e!=null){
Toast.makeText(LoginActivity.this,"User data didn't save!",Toast.LENGTH_SHORT).show();
}else{
openMainActivity();}
}
});
答案 0 :(得分:1)
请看下面的代码。为什么要调用user.signUpInBackground();再次? 我认为它应该是 user.saveInBackground(); 另外,请检查字段的数据类型以确保输入正确的数据类型(例如:数字的int / float / double)
else if (user.isNew()) {
Profile profile = Profile.getCurrentProfile();
user.put("gender", "");
user.put("location", "");
user.put("age", "");
user.put("meet", "");
user.put("status", "");
user.put("link", "");
user.put("fullname", profile.getName());
user.setEmail("");
user.signUpInBackground();
ParseInstallation installation = ParseInstallation.getCurrentInstallation();
installation.put("user", user.getObjectId());
installation.put("fullname", user.getString("fullname"));
installation.saveInBackground();
openMainActivity();
}

从解析文档中,user.isNew() - &gt;用户注册并通过Facebook登录!
ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() {
@Override
public void done(ParseUser user, ParseException err) {
if (user == null) {
Log.d("MyApp", "Uh oh. The user cancelled the Facebook login.");
} else if (user.isNew()) {
Log.d("MyApp", "User signed up and logged in through Facebook!");
} else {
Log.d("MyApp", "User logged in through Facebook!");
}
}
});

如果它不起作用,请尝试以下代码以了解您的用户是否成功保存
user.saveInBackground(new SaveCallback() {
@Override public void done(ParseException e) {
if (e != null) {
Log.e("Exception", e.getMessage());
return;
}
Log.e("OK", "Saved!");
}});
