【问题描述】：
我尝试在我的应用中实现帐户管理器，以避免用户每次打开应用时都必须登录。
所以基本上，我已经有了我的身份验证活动，用户可以在其中输入其登录名和密码，以及我们从服务器接收令牌的位置（目前身份验证是基本的）。现在我想添加 AccountManager 但我真的不明白哪个部分会去哪里。
我需要的是非常基本的：
- 如果我以前从未登录过，请添加一个帐户
- 如果我的帐户存在则自动登录
- 如果自动身份验证不起作用，请在服务器上获取新令牌
这是我的代码：
AuthenticationActivity.java
public class AuthenticationActivity extends Activity {
private EditText editTextUsername;
private EditText editTextPassword;
private Button buttonLogin;
private ProgressBar spinner;
private TextView error;
private TextView register;
private boolean accountRegistred;
AccountManager accountManager;
public static final String AUTHENTICATION = "authentication"; //action
private ConnectionSuccessReceiver connectionSuccessReceiver = new ConnectionSuccessReceiver();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.authentification);
accountManager = AccountManager.get(this);
Account[] accounts = accountManager.getAccountsByType("login");
if (accounts.length > 0) {
//If there is an account
} else {
accountRegistred = false;
editTextUsername = (EditText) findViewById(R.id.editText_login);
editTextUsername.setVisibility(View.VISIBLE);
editTextPassword = (EditText) findViewById(R.id.editText_password);
editTextPassword.setVisibility(View.VISIBLE);
buttonLogin = (Button) findViewById(R.id.button_connection);
buttonLogin.setVisibility(View.VISIBLE);
error = (TextView) findViewById(R.id.textView_error);
register = (TextView) findViewById(R.id.textView_register);
register.setVisibility(View.VISIBLE);
spinner = (ProgressBar) findViewById(R.id.progressBar);
buttonLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//Here we start the service which will reach the server
Intent i = new Intent(getApplicationContext(), AuthenticationService.class);
i.putExtra("username", editTextUsername.getText().toString());
i.putExtra("password", editTextPassword.getText().toString());
getApplication().startService(i);
spinner.setVisibility(View.VISIBLE);
error.setVisibility(View.INVISIBLE);
}
});
register.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(new Intent(AuthenticationActivity.this, RegisterActivity.class));
}
});
}
registerReceiver(connectionSuccessReceiver, new IntentFilter(AUTHENTICATION));
}
private class ConnectionSuccessReceiver extends BroadcastReceiver {
//Called when the server returns success after authentication, we get the TOKEN here
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getStringExtra("STATE").equals("CONNECTED")) {
Intent i = new Intent(AuthenticationActivity.this, MainActivity.class);
i.putExtra("TOKEN", intent.getStringExtra("TOKEN"));
startActivity(i);
} else {
spinner.setVisibility(View.INVISIBLE);
error.setVisibility(View.VISIBLE);
}
finish();
}
}
@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(connectionSuccessReceiver);
}
}
AuthenticatorService.java
public class AuthenticatorService extends Service {
/**
* The implementation of the class |AccountAuthenticatorImpl|.
* It is implemented as a singleton
*/
private static AccountAuthenticator accountAuthenticator = null;
/**
* The main constructor.
*/
public AuthenticatorService() {
super();
}
/**
* The bind method of the service.
* @param intent The intent used to invoke the service
* @return The binder of the class which has implemented |AbstractAccountAuthenticator|
*/
@Override
public IBinder onBind(Intent intent) {
IBinder ret = null;
if (intent.getAction().equals(android.accounts.AccountManager.ACTION_AUTHENTICATOR_INTENT)) {
ret = getAuthenticator().getIBinder();
}
return ret;
}
/**
* The method used to obtain the authenticator. It is implemented as a singleton
* @return The implementation of the class |AbstractAccountAuthenticator|
*/
private AccountAuthenticator getAuthenticator() {
if (AuthenticatorService.accountAuthenticator == null) {
AuthenticatorService.accountAuthenticator = new AccountAuthenticator(this);
}
return AuthenticatorService.accountAuthenticator;
}
public class AccountAuthenticator extends AbstractAccountAuthenticator {
private Context context;
public AccountAuthenticator(Context context) {
super(context);
this.context = context;
}
@Override
public Bundle editProperties(AccountAuthenticatorResponse accountAuthenticatorResponse, String s) {
return null;
}
@Override
public Bundle addAccount(AccountAuthenticatorResponse response, String accountType, String authTokenType, String[] requiredFeatures, Bundle options) throws NetworkErrorException {
Bundle reply = new Bundle();
Intent i = new Intent(context, AuthenticationActivity.class);
i.setAction("com.readyo.app.authentication.addnewaccount");
i.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE, response);
i.putExtra("AuthTokenType", authTokenType);
reply.putParcelable(AccountManager.KEY_INTENT, i);
return reply;
}
@Override
public Bundle confirmCredentials(AccountAuthenticatorResponse accountAuthenticatorResponse, Account account, Bundle bundle) throws NetworkErrorException {
return null;
}
@Override
public Bundle getAuthToken(AccountAuthenticatorResponse accountAuthenticatorResponse, Account account, String s, Bundle bundle) throws NetworkErrorException {
return null;
}
@Override
public String getAuthTokenLabel(String s) {
return null;
}
@Override
public Bundle updateCredentials(AccountAuthenticatorResponse accountAuthenticatorResponse, Account account, String s, Bundle bundle) throws NetworkErrorException {
return null;
}
@Override
public Bundle hasFeatures(AccountAuthenticatorResponse accountAuthenticatorResponse, Account account, String[] strings) throws NetworkErrorException {
return null;
}
}
}
我还有通过 HTTP 访问服务器的代码，但我不确定它在这里是否重要。
感谢您的宝贵时间。
