I have calculated distance between two locations inside adapter but now I cannot sort the RecyclerView based on distance. Because the calculated distance is not from helper class.
Following is the Code from Adapter Class:
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
Context context;
ArrayList<JobSeekerClass> list;
Double JSlat, JSlng;
LocationManager locationManager;
String provider;
public MyAdapter(Context context, ArrayList<JobSeekerClass> list) {
this.context = context;
this.list = list;
}
@NonNull
@Override
public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.item, parent, false);
return new MyViewHolder(v);
}
@Override
public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
provider = locationManager.getBestProvider(new Criteria(), false);
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
Location location = locationManager.getLastKnownLocation(provider);
JobSeekerClass JobSeeker = list.get(position);
//Job Seeker Lat Lng
JSlat= location.getLatitude();
JSlng= location.getLongitude();
LatLng Job_Seeker= new LatLng(JSlat, JSlng);
//Job Provider Lat Lng
String JPlat= JobSeeker.getJplongitude();
String JPlng= JobSeeker.getJplatitude();
Double JP_lat= Double.parseDouble(JPlat);
Double JP_lng= Double.parseDouble(JPlng);
LatLng Job_Provider= new LatLng(JP_lat, JP_lng);
//Calculating Distance
Double Distance= SphericalUtil.computeDistanceBetween(Job_Seeker, Job_Provider);
//Distance in Kilometers
Double Distance_in_KM= Distance/1000;
Double dist= Math.floor(Distance_in_KM);
String distance_string= dist.toString();
//Setting Text for Calculated Distance in RecyclerView
holder.faasla_Digit.setText(distance_string);
//Setting Text for JobSeeker City
holder.City.setText(JobSeeker.getJPlocation());
holder.PhoneNumber.setText(JobSeeker.getJPphone_no());
holder.find_job_Location.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int position = holder.getAdapterPosition();
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q=" + list.get(position).getJplongitude() + "," + list.get(position).getJplatitude() + "&mode=l"));
intent.setPackage("com.google.android.apps.maps");
if (intent.resolveActivity(context.getPackageManager()) != null) {
context.startActivity(intent);
}
}
});
//Salary Digit Sound for corresponding values
holder.Salary.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (holder.Salary.getText().equals("1000")) {
MediaPlayer mplayer = MediaPlayer.create(context.getApplicationContext(), R.raw.aikhazar);
mplayer.start();
}
}
});
}
@Override
public int getItemCount() {
return list.size();
}
public static class MyViewHolder extends RecyclerView.ViewHolder implements LocationListener {
TextView Salary, City, PhoneNumber, city_text, phone_number_text, salary_text,
raasta_maloom_karain, faasla_Digit;
Button find_job_Location;
public MyViewHolder(@NonNull View itemView) {
super(itemView);
City = itemView.findViewById(R.id.tvJobLocation);
PhoneNumber = itemView.findViewById(R.id.tvPhoneNo);
Salary = itemView.findViewById(R.id.tvSalary);
city_text = itemView.findViewById(R.id.Sheher);
phone_number_text = itemView.findViewById(R.id.raabta_number);
salary_text = itemView.findViewById(R.id.mahana_tankhuwa);
raasta_maloom_karain = itemView.findViewById(R.id.raasta_maloom_karain);
find_job_Location = itemView.findViewById(R.id.find_job_location);
faasla_Digit = itemView.findViewById(R.id.faasla_digit);
}
@Override
public void onLocationChanged(@NonNull Location location) {
}
@Override
public void onLocationChanged(@NonNull List<Location> locations) {
LocationListener.super.onLocationChanged(locations);
}
@Override
public void onFlushComplete(int requestCode) {
LocationListener.super.onFlushComplete(requestCode);
}
@Override
public void onProviderEnabled(@NonNull String provider) {
LocationListener.super.onProviderEnabled(provider);
}
@Override
public void onProviderDisabled(@NonNull String provider) {
LocationListener.super.onProviderDisabled(provider);
}
}
}
Following is the Code from Helper Class:
public class JobSeekerClass {
String JPfullname, JPphone_no, JPemail, JPaddress, JPjob_title,
JPlocation, JPsalary, JPDMwages, JPFNwages, jplongitude, jplatitude;
public JobSeekerClass()
{
}
public JobSeekerClass(String JPfullname, String JPphone_no, String JPemail, String JPaddress,
String JPjob_title, String JPlocation, String JPsalary, String JPDMwages,
String JPFNwages, String jplongitude, String jplatitude)
{
this.JPfullname= JPfullname;
this.JPphone_no= JPphone_no;
this.JPemail= JPemail;
this.JPaddress= JPaddress;
this.JPjob_title= JPjob_title;
this.JPlocation= JPlocation;
this.JPsalary= JPsalary;
this.JPDMwages= JPDMwages;
this.JPFNwages= JPFNwages;
this.jplongitude= jplongitude;
this.jplatitude= jplatitude;
}
public String getJplongitude() {
return jplongitude;
}
public void setJplongitude(String jplongitude) {
this.jplongitude = jplongitude;
}
public String getJplatitude() {
return jplatitude;
}
public void setJplatitude(String jplatitude) {
this.jplatitude = jplatitude;
}
public String getJPfullname() {
return JPfullname;
}
public void setJPfullname(String JPfullname) {
this.JPfullname = JPfullname;
}
public String getJPphone_no() {
return JPphone_no;
}
public void setJPphone_no(String JPphone_no) {
this.JPphone_no = JPphone_no;
}
public String getJPemail() {
return JPemail;
}
public void setJPemail(String JPemail) {
this.JPemail = JPemail;
}
public String getJPaddress() {
return JPaddress;
}
public void setJPaddress(String JPaddress) {
this.JPaddress = JPaddress;
}
public String getJPjob_title() {
return JPjob_title;
}
public void setJPjob_title(String JPjob_title) {
this.JPjob_title = JPjob_title;
}
public String getJPlocation() {
return JPlocation;
}
public void setJPlocation(String JPlocation) {
this.JPlocation = JPlocation;
}
public String getJPsalary() {
return JPsalary;
}
public void setJPsalary(String JPsalary) {
this.JPsalary = JPsalary;
}
public String getJPDMwages() {
return JPDMwages;
}
public void setJPDMwages(String JPDMwages) {
this.JPDMwages = JPDMwages;
}
public String getJPFNwages() {
return JPFNwages;
}
public void setJPFNwages(String JPFNwages) {
this.JPFNwages = JPFNwages;
}
public String toString()
{
return this.JPlocation + "";
}
}
Now I(JobSeeker) have fetched my current location in MyAdapter and computed the distance using the LatLng I got from getJplatitude() and getJplongitude() from JobSeekerClass(). It is actually Job Provider class. I mistakenly named it as JobSeekerClass. I have calculated distance using distUtils and now, I want to sort my recyclerView based on the computed distance. How can I do that?
