SessionManagement类

// Constructor
public SessionManagement(Context context) {
this._context = context;
pref = _context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
editor = pref.edit();
}
/**

public void createLoginSession(String username, String accesstoken, String tokentype, String masterid, String name, Integer access) {
// Storing login value as TRUE
editor.putBoolean(IS_LOGIN, true);
editor.putString(KEY_USERNAME, username);
// Storing name in pref
editor.putString(KEY_access_token, accesstoken);
// Storing email in pref
editor.putString(KEY_TOKEN_TYPE, tokentype);
editor.putString(KEY_MASTER_ID, masterid);
editor.putString(KEY_TOKEN_TYPE, tokentype);

editor.putInt(KEY_Access, access);
// commit changes
String user_name_new = pref.getString(KEY_USERNAME, null);
Log.d("TAG", "Pass user name :" + username + " user_name_new:" + user_name_new);
editor.commit();
}
/**
* Check login method wil check user login status

* Else won't do anything
*/
public void checkLogin() {
// Check login status
if (!this.isLoggedIn()) {
// user is not logged in redirect him to Login Activity
Intent i = new Intent(_context, Login.class);
// Closing all the Activities
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// Add new Flag to start new Activity
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Staring Login Activity

}
}
/**

public HashMap<String, String> getUserDetails() {

如何在LOgin CLass中使用SessionManagement类在本地存储信息?
How the SessionManagement Class be used in the LOgin CLass to store information Locally??
推荐答案
尝试一下，
if (response.trim().equals("success")) {
//add these 2 lines
SessionManagement session=new SessionManagement(Login.this);
session.createLoginSession(username, accesstoken,tokentype, masterid,name, access);
openProfile();
} else {
Toast.makeText(Login.this, response, Toast.LENGTH_LONG).show();
}
编辑您的createLoginSession函数:
Edit your createLoginSession function:
/**
* Create login session
* */
public void createLoginSession(String username, String accesstoken,String tokentype, String masterid,String name, Integer access){
// Storing login value as TRUE
editor.putBoolean(IS_LOGIN, true);
editor.putString(KEY_USERNAME, username);
// Storing name in pref
editor.putString(KEY_access_token, accesstoken);
// Storing email in pref
editor.putString(KEY_TOKEN_TYPE, tokentype);
editor.putString(KEY_MASTER_ID, masterid);
editor.putString(KEY_TOKEN_TYPE, tokentype);
editor.putString(KEY_NAME, name);
editor.putInt(KEY_Access, access);
// commit changes
editor.commit();
String user_name_new=pref.getString(KEY_USERNAME, null)
Log.d("TAG","Pass user name :"+username+" user_name_new:"+user_name_new);
}
