Can ListView host TextView items that are also displayed in a separate TextView

I'm having a problem changing a TextView to a ListView. Originally, the app had a button that when clicked, runs tests to a bluetooth device and displays the results in a textview. I modified the app to contain two textviews that have the last text results and a separate xml file (connected with viewflipper) to go to a second textview that contains all of the test results, until the user clears the textview by clicking a button. I followed along with this example and checked what I was entering in the ArrayAdapter section of the code, and it appears to be what is required according to the developer's guide, but I still get his error:
Cannot resolve constructor 'ArrayAdapter(com.example.android.stardustscanner.ScannerFragment, int, int, java.lang.String)'
Why am I getting this error?
My .java file that I am making all the changes in is very long and contains a lot of thins that aren't relevant to this question and doesn't fit in the question box, so I'll try to only include the relevant parts. The error is towards the bottom with this line:
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, R.layout.fragment_bluetooth_scanner, R.id.textView, saveData);

I have three xml files associated with this problem, but because of space I'll only include the one that contains the ListView and remove the other buttons.
view_list.xml contains the ListView:

The error was with ArrayAdapter. I changed the decloration from
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,
R.layout.fragment_bluetooth_scanner, R.id.textView, saveData);
to
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, android.R.id.text1, listItems);
It now builds the project and displays the listview.

Can't use the SASLXFacebookPlatformMechanism class in making android xmpp facebook chat client

I m trying to make a simple version facebook messenger.The code that i used has worked well for gtalk and requires facebook authentication to be used for chatting with facebook friends.For that, i have used SASLXFacebookPlatfromMechanism class where i will store the api token and api key along with the apisecret of my app. The problem is SASLXFacebookPlatfromMechanism.java class is full of errors which i cannot resolve at all.Here are my classes-

The code shows error stating

I am also confused on how to use this SASLXFacebookPlatformMechanism.java class in my MainActivity.class.I have been trying to get a sense of how it works but failing.A complete guideline on how to develop a xmpp facebook chat client using asmack library would be appreciated since the internet lacks enough documentation on it.Thanks.

Java Sensor filter correction

I am engaging with android sensor data filtering. At the same time, I am not good at JAVA. It needs to integrate "FixFilter" class with main source code which starts ENS492SenorsActivity.

How to decode JSON data sent to server by TripTracker?

I am using a PHP MySQL server model. I want to decode the JSON data that is sent to the server by this code. Any help would be appreciated. The app sends current GPS coordinates to inputed server as JSON array object. I would like to decode it to share with other android users. Thanks a lot. This is the Android code.

You can decode the data using json_decode()
<?php
$json = ""; // JSON data
$json_obj = json_decode($json); // As Object
$json_arr = json_decide($json,true) // As Array
var_dump($json_obj);
print_r($json_arr);
// Store Array to database using serialize function
$data = serialize($json_array); // Array will be converted into string
?>
