how to create a menu item hide or visible - android

I want to create a menu the item, where when the item is clicked then he will disappears temporarily. as an example: I make a menu GpsOn and GpsOff, if the GpsOn clicked then he would disappears and the only remaining GpsOff, and conversely. is there any tutorial or code that can help me??
My Code :
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
if(isGpsOn){menu.getItem(MENU_GpsOn).setVisible(false);menu.getItem(MENU_GpsOff).setVisible(true);}
else { menu.getItem(MENU_GpsOn).setVisible(true);menu.getItem(MENU_GpsOff).setVisible(false);}
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
session = new SessionManager(getApplicationContext());
session.checkLogin();
HashMap<String, String> user = session.getUserDetails();
String name = user.get(SessionManager.KEY_NAME);
switch (item.getItemId()) {
case MENU_Secure:
try {
sendSMS(name, "secure");
} catch (Exception e) {
Toast.makeText(this, "Gagal karena " + e.toString(),
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
return(true);
case MENU_Unsecure:
try {
sendGPS(name, "notsec");
} catch (Exception e) {
Toast.makeText(this, "Gagal karena " + e.toString(),
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
return(true);
case MENU_GpsOn:
try {
sendMobil(name, "gps on");
} catch (Exception e) {
Toast.makeText(this, "Gagal karena " + e.toString(),
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
isGpsOn=true;
// ((MenuItem)findViewById(MENU_GpsOff)).setVisible(false);
return(true);
case MENU_GpsOff:
try {
sendGPSOff(name, "gpsoff");
} catch (Exception e) {
Toast.makeText(this, "Gagal karena " + e.toString(),
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
isGpsOn=false;
return(true);
}
return(super.onOptionsItemSelected(item));
}

Try this,
public boolean checkHide = false
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId()){
case GPS:
if(checkHide){
checkHide=false;
item.setTitle("GPS_ON");
// ToDo your function
}
else{
checkHide=true;
item.setTitle("GPS_OFF");
// ToDo your function
}
}

What I think you need is Toggle Button. To create one such button, take a look at this tut here, as well as this one and this one.
This is of course, if I understood your requirements correctly.

Offline login only when a valid user login online

I am developing an app. My goal is that user can login online and offline both, but for the first time user should login online enters their credentials (userid and password) and save the user's credentials when user is valid for offline mode(remote location where internet is not available). To check the credentials I used a webservice which will check that user id and password whether valid or not. I am able to consume webservice, its also check whether user is valid or not and able to save the userid and encrypted password and also achieve to compare passwrod with store password in database. But the problem I am facing is that when the userid or password is not correct it saves the credentials in sqlite database. And when I'm on offline mode I can login with incorrect password. I don't want that I want it saves credential only when user is authenticated. Below I shared my code. Need help I don't get it in where line I have to call offline method. Thanks in advance.
Fuction for Login Button:
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// preventing double, using threshold of 1000 ms
if (SystemClock.elapsedRealtime() - lastClickTimeBtnLogin < Utilities.BTN_DOUBLE_CLICK_STOP_TIME) {

lastClickTimeBtnLogin = SystemClock.elapsedRealtime();

// Login Logic
try {

Did you rebuild/clean the project? try build->clean project. make sure you also have these resources in the respective folders i.e. homepage.xml in your res/menu folder and should have an item with i.d action_settings

restoring application background with sharedpreference

I understand that a similar question has been asked but I am seriously stuck on this problem.
When I close the application, it says "Saving Data" which means my on stop method is being called but when I re open the app, it fails to mention that it is "getting data" meaning my onStart method is not being called.
The middle block of code seems to be the most important, I just wanted to include all of it so that if someone were to bump into my situation again, they could see everything.
How do I use the sharedpreferences class in this situation to save the background color and call the onStart method when I reopen the application?
As of now, it always resorts to the default Colour.
Thank you for your time.

onStart is called after onCreate, please remove this
if (Color_Value!= null){

and you can retrieve the color fron SharedPreferences directly in onCreate.

Loading text file into EditText but file gets cut off

You should iterate over your Scanner until hasNext() return false to make sure the whole file is read. See more information here: Beware of using java.util.Scanner with ā€œ/zā€
StringBuilder sb = new StringBuilder();
Scanner scanner = new Scanner(tempFile).useDelimiter("\\Z");
while (scanner.hasNext()) {
sb.append(scanner.next());
}
et.setText(sb);

How connect to sql server express with android

Firstly I wan't you to know that I search really hard for my problem but I found nothing ...
I can't connect to sql server express instance with android application however I try to connect with jdbc:jtds:sqlserver the driver of sourceforge.
I don't forget to add this line in the manifest file :
<uses-permission android:name="android.permission.INTERNET" />
And the error message is Unable to get information from sql server :HostName
Here my source code perhaps there is something wrong :
