Adapter not working inside asyncTask when notifyDataSetChanged?

i've got problem when trying to implement loadmore, exactly problem is adapter.notifyDataSetChanged inside AsyncTask. i trying to implement from this tuts https://github.com/shontauro/android-pulltorefresh-and-loadmore
, this tuts try implementing using extend ListActivity in Class, but i'm using extend Fragment, anyway this code is working, but just data not updated when trying to get data from loadmore. i'm sorry if my language is bad :)
this is my class :

please tell me why this is not working ?

mListItems is not used for anything.
mNames is the one linked to the adapter, not mListItems which you are filling in the AsyncTask, may be you should review that.
mListItems.addAll(Arrays.asList(mNames));
adapter = new ArrayAdapter<String>(getActivity(), R.layout.tour_listview, R.id.MobileArray, mNames);
and then you do
for (int i = 0; i < mobileArray.length; i++) {
mListItems.add(mobileArray[i]);
}

"Real time" answer in a conversion program

How to code in java for real time output which displayed on the screen,as soon as user inputs some value with keyboard, with out a calculate button in activity in a simple conversion program? I have given the code below. In that it takes one input value and "FROM" and "TO" to convert the value and showed in the display with press of "calculate" button
Now I want to eliminate the "calculate" button and as soon as user inputs the numbers want to show the answer to the display
My code given below. Please let me know any additional information required

}

You are looking for a text change listener.
from.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
calculateNewResult(s);
}
#Override
public void afterTextChanged(Editable s) {
}
});
You may also want to use an item select listener on the spinners.
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
updateTheCalculation();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

Saving EditTexts on App close

You should have a look here You should take a look at the shared preferences, http://developer.android.com/reference/android/content/SharedPreferences.html, I used this and helped me get through it, You need to save each edit text that you want to save. and as for each row I would suggest making an array or loop for saving the edit boxes in the rows

didn't read your code bro, but answering in concern to your question title :
override onStop and save the data to Shared Preferences, its very easy to use:
//To save your data
SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
editor.putString("name", "Elena");
editor.putInt("idName", 12);
editor.commit();
//to extract your data in onCreate or whenever you feel like:
SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE);
String restoredText = prefs.getString("text", null);

You will want to look into SharedPreferences, once you do you will basically be saving your values in SharedPreferences in an onPause() / onDestroy() method, and then in your onResume() / onCreate() methods you will retrieve the previously stored data
Edit: You can retrieve a string from an EditText in the following way
String toStore = EditText.getText().toString();
and then store it
getSharedPreferences("PREFERENCE",MODE_PRIVATE).edit().putString("KEY", toStore);
so...
public void onPause(){
super.onPause();
String toStore = EditText.getText().toString();
getSharedPreferences("PREFERENCE",MODE_PRIVATE).edit().putString("KEY", toStore);
}
public void onResume(){
super.onResume();
String toStore = PreferenceManager.getDefaultSharedPreferences(context).getString("KEY", "defaultStringIfNothingFound");
EditText.setText(toStore);
}

You may use onSavedInstanceState and onRestoreInstanceState methods of activity !
So in onSavedInstanceState (called before your activity pauses) you may save your `EditText' values to the bundle,
And restore them back in onRestoreInstance state.
You can use the link by #Kaique for more reference,
and also this answer https://stackoverflow.com/a/16769864/826657 and all related answers here.

You should take a look at the shared preferences, http://developer.android.com/reference/android/content/SharedPreferences.html

Currency app needs update

I just need som minor help now. The app runs great but when you enter for ex. USD, 2 TO SEK it results 13,38. But if i change the amount to 3 nothing happens. I would have to change the currencys back and forth to make a change. I would like the app to change the result as soon as i change the value. Please help!:)

}

}
}

Your editAmount.getText().toString() value is NULL(empty). And you still trying to convert this value into DOUBLE so you got NumberFormatException .
Check editText value before parsing like:
if(!editAmount.getText().toString().equals(""))
{
//Do your job
}
Or another way is
if (!TextUtils.isEmpty(editAmount.getText().toString())) {
//Do your job
}

EDITED:
What i want to do is when i click on thw spinner it will collapse/open down and i will have for each item and box of it self and it will be in row for example i clicked on the spinner i will see now under it:
Hello
Bye
Daniel
and now if i click on Hello it will put the Hello in the textView1 if i click on the Bye it will put it also in textView1 and so on.
But the graphics the designing of the spinner i want it to be that when i click on it it will collapse down and show me the items in a row so i can click and select each item in a single click.
Now what i did is just adding the spinner a text "Please Select An Item"
I uploaded image of how i wanted it to be like for example:

That is the behavior of the spinner, there is always a selected item.
You can create a flag and use that in an override of the onItemSelected, put a counter in there and use that to ignore the first time in.
Like this:
private int spinnerSelectCount = 0;
#Override
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
if(spinnerSelectCount == 0) {
// Do nothing... initial item on spinner display is the selected item
} else {
// your code to process spinner selection here
}
}
});
EDIT
You need to put your string as the first item in your array, not a separate string.
itemsList = new ArrayList<String>();
itemsList.add("Please Select An Item");
itemsList.add(Arrays.toString(Locale.getAvailableLocales()));
Then call the spinner using the array:
dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,itemsList);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_item);
spinner.setAdapter(dataAdapter);
And since you're doing that you should change the filter to be based on position, not count.
#Override
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
if(pos == 0) {
// Do nothing... initial item on spinner display is the selected item
} else {
// your code to process spinner selection here
textview.setText(itemsList.get(pos));
}
}
});
EDIT 2
Are you looking for multi-selection? That's not possible with a standard spinner, it is set up to select one item only. If you are really looking to select multiple items you need to use a list or create a custom spinner.
Fortunately, it looks like someone has already done that. You can find the code in this SO Answer
EDIT 3
The MultiSpinner does not need a new project. You merely create a new class and use that to populate your spinner.
1) Create a new class called MultiSpinner
2) Copy the code from link (leave out the package name as you'll want to use your own)
3) In your xml call out the spinner like so (replacing com.yourpackage.name with your actual package name):
<com.yourpackage.name.MultiSpinner android:id="#+id/multi_spinner" />
4) Call the spinner as shown in the link:
MultiSpinner multiSpinner = (MultiSpinner) findViewById(R.id.multi_spinner);
multiSpinner.setItems(items, getString(R.string.for_all),
this);

An easy solution would be to set the first item of the spinner to a text like "Please select a value..". Then in the code..
#Override
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
if(pos == 0) {
// do nothing..
} else {
// your code..
}
}
});
