How can I rearrange the data from database in a ListView?

everyone. I have an ArrayList of the data and a ListView to showing up the list of the data. Now what I want to do is rearrange the data when I press the button and sort the data in which data has the highest result.
Here is my code:
public class MainActivity extends AppCompatActivity {
private TextView mTextMessage;
String[] dataDetail;
ArrayList<dataDetail> allDetail = new ArrayList<>();
ListView detailList;
final Context context = this;
final int min = 0;
final int max = 10;
final int random = new Random().nextInt((max - min) + 1) + min;
Button reorder = findViewById(R.id.arrangeId);
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_home:
mTextMessage.setText(R.string.title_home);
return true;
case R.id.navigation_dashboard:
mTextMessage.setText(R.string.title_dashboard);
return true;
}
return false;
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
detailList = findViewById(R.id.dataView);
mTextMessage = (TextView) findViewById(R.id.message);
BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
new GetData().execute();
}
private class GetData extends AsyncTask<Void, Void, ArrayList<dataDetail>> {
protected ArrayList<dataDetail> doInBackground(Void... voids) {
HttpURLConnection urlConnection;
InputStream in = null;
try {
URL url = new URL("http://10.0.2.2:8080/projectServer/DataDetailDB?getdata=true");
urlConnection = (HttpURLConnection) url.openConnection();
in = new BufferedInputStream(urlConnection.getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
String response = convertStreamToString(in);
System.out.println("Server response = " + response);
try {
JSONArray jsonArray = new JSONArray(response);
dataDetail = new String[jsonArray.length()];
for (int i = 0; i < jsonArray.length(); i++) {
final String customerName = jsonArray.getJSONObject(i).get("customerName").toString();
final String carName = jsonArray.getJSONObject(i).get("carName").toString();
final String appointmentDate = jsonArray.getJSONObject(i).get("appointmentDate").toString();
final String email = jsonArray.getJSONObject(i).get("email").toString();
final String issueDescribe = jsonArray.getJSONObject(i).get("issueDescribe").toString();
final String timeForJob = jsonArray.getJSONObject(i).get("timeForJob").toString();
final String costForJob = jsonArray.getJSONObject(i).get("costForJob").toString();
final String reliableOnCar = jsonArray.getJSONObject(i).get("reliableOnCar").toString();
final String distanceJob = jsonArray.getJSONObject(i).get("distance").toString();
dataDetail tData = new dataDetail(customerName, carName, appointmentDate, email, issueDescribe, timeForJob, costForJob, reliableOnCar, distanceJob);
allDetail.add(tData);
System.out.println("customername = " + customerName + "carname = " + carName + "appointmentdate = " + appointmentDate +
"email = " + email + "describe = " + issueDescribe + "time = " + timeForJob + "cost = " + costForJob + "reliable = " + reliableOnCar
+ "dis = " + distanceJob);
dataDetail [i] = "Name: " + customerName + "\n" + "Appointment Date: " + appointmentDate;
reorder.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
float finalResult = random * Float.parseFloat(timeForJob) + random * Float.parseFloat(reliableOnCar) +
random * Float.parseFloat(distanceJob) + random * Float.parseFloat(costForJob);
System.out.print("Test result " + finalResult + " ");
/* Trying to sort the data here which has the highest finalResult
* will going to the top of the list */
allDetail = new ArrayList<String>(Arrays.asList(dataDetail));
Collections.sort(allDetail);
ArrayAdapter newList = new ArrayAdapter(context, android.R.layout.simple_list_item_1, dataDetail);
newList.setAdapter(theList);
}
});
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(ArrayList<dataDetail> dataDetailArrayList) {
super.onPostExecute(dataDetailArrayList);
ArrayAdapter theList = new ArrayAdapter(context, android.R.layout.simple_list_item_1, dataDetail);
detailList.setAdapter(theList);
}
}
public String convertStreamToString(InputStream is) {
java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A");
return s.hasNext() ? s.next() : "";
}
}
But when I try to use sort I get the error says it's incompatible types.
allDetail = new ArrayList<String>(Arrays.asList(dataDetail));
Collections.sort(allDetail);
The finalResult will do the calculation and get the final result for every data it retrieves from the database. And now I just want to reorder it automatically, This is the logcat:
Please anyone can help how can I do the rearrange for the listview?

Collections.sort() will work. Its your problem related to how your are storing your data in list

The mistake that you have made is that you assume that
import static com.example.saiid.listecompte.fetchcompte.dataParsed;
will automatically just be the dataParsed Variable you need. What that line does is that it gets the default value of dataParsed (from a default fetchcompte instance). Since you make another instance of a fetchcompte object [called process] (which you are using to populate its dataParsed variable) simply access the dataParsed variable of that instance.
So instead of using:
textView_type.setText(dataParsed[i]);
You can use:
textView_type.setText(process.dataParsed[i]);
But to do this you will need to somehow access the process variable in your adapter class.

How to update the Recylerview View items after displayed First Json URL In android

I having a problem update the Item in Recycler View.I will explain clearly about my problem.
I am using two Json URL's first Json URL can send the items to model class.
after completed this called the adapter, then update the second Json URL items with the adapter by using setter model class.
so that's why called adapter.notifyitemchanged, but only one time can updated items next time while looping doesn't update the items display empty for second time.

Note: While looping first time can set the item in setter model class but second couldn't set the item to model class.
Anyone solve this problem glad to appreciate.
Thanks in advance

The problem is volley doesn't wait for the request to be completed. So as the first call is made within seconds other call will be also made. So, you need to create an interface which will be called when the first webservice is called, and than in interface call other webservice and than notifyDataSet.

how do i apply a condition when the fields are empty then it never post the data to the mysql data base
