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

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

Use one ViewHolder and define three fields and show hide views according status.
Maintain Status in list not in adapter.
Because list item recreated on list view scroll.
You can see same thumbnail in multiple list items as Android reuses the view of list item.
Care needs to be taken that you make the thumbnail invisible or use 'Icon which suggests no image' if you don't have the correct image for that position of list item. This check has to be made in getView method of your adapter of the list.
I have custom adapter list view with two spinner view.
Each spinner has a background process. On initializing, the spinner view.OnItemSelectedListener is recursively called unnecessarily without any external input to the listener

How to avoid unnecessarily calling of view.OnItemSelectedListener of spinner view On initializing custom adapter list view
You can't stop or avoid calling of onItemSelectedListener on initialization. But you can prevent this by declare an integer and set value as 0 and while on calling getview method, check the integer with size of data(Your array list size).if the integer is less than the size than increment the integer value else do your background work. But it's not right way to do because when you scroll the listview the same problem rise again. You do this if you have fixed array list size. It is better to use AutoCompleteTextView instead of SpinnerView.
It gets called for the selection of the first item(Kind of default value).
Try one thing don't set adapter to spinner if row!=null for ex:
if (row == null) {
holder = new ClientListHolder();
row = inflater.inflate(layoutResourceId, parent, false);
holder.tv_no = (TextView) row
.findViewById(R.id.tv_clientwaitlayout_no);
holder.tv_name = (TextView) row
.findViewById(R.id.tv_clientwaitlayout_name);
holder.tv_status = (Spinner) row
.findViewById(R.id.tv_clientwaitlayout_status);
holder.tv_therapist = (Spinner) row
.findViewById(R.id.tv_clientwaitlayout_therapist);
holder.iv_edit=(ImageView) row.findViewById(R.id.btn_clientwaitlayout_edit);
holder.iv_action = (ImageView) row
.findViewById(R.id.btn_clientwaitlayout_action);
holder.tv_unchange_therapist=(TextView) row.findViewById(R.id.tv_clientwaitlayout_unchange_name);
holder.tv_unchange_status=(TextView) row.findViewById(R.id.tv_clientwaitlayout_unchange_status);
holder.tv_therapist.setAdapter(TherapistAdapter);
holder.tv_status.setAdapter(StatusAdapter);
row.setTag(holder);
} else {
holder = (ClientListHolder) row.getTag();
}
I'm loading a text file into an EditText but the file only gets partially loaded. I've tried two different files and get the same result. One file gets cut off halfway through line 35 and the other line 37. No idea why.

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 “/z”
StringBuilder sb = new StringBuilder();
Scanner scanner = new Scanner(tempFile).useDelimiter("\\Z");
while (scanner.hasNext()) {
sb.append(scanner.next());
}
et.setText(sb);
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.
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
