Twice data in RecyclerView

How can i fix twice data error.
After scrolling inside the RecyclerView, I am having a issue which is twice data.
Here is my Activity:
apiInterface = ApiClient.getApiClient().create(ApiInterface.class);
Call<List<Contacts>> call = apiInterface.chat(getUserLogin,friendId);
call.enqueue(new Callback<List<Contacts>>() {
#Override
public void onResponse(Call<List<Contacts>> call, Response<List<Contacts>> response) {

CustomAdapterOfChat adapter = new CustomAdapterOfChat(contacts, ChatActivity.this);
recyclerView.setAdapter(adapter);
size = String.valueOf(contacts.size());
}
#Override
public void onFailure(Call<List<Contacts>> call, Throwable t) {
Toast.makeText(getApplicationContext(), "Error\n"+t.toString(), Toast.LENGTH_LONG).show();
}
});
My customAdapter ViewHolder
public class CustomAdapterOfChat extends RecyclerView.Adapter<CustomAdapterOfChat.MyViewHolder> {

You are getting data from SharedPreferences which is time consuming task however you can edit your code this way and check the output.
public class CustomAdapterOfChat extends RecyclerView.Adapter {
private List<Contacts> contacts;
private Context context;
String getUserLogin;
public CustomAdapterOfChat(List<Contacts> contacts, Context context) {
this.contacts = contacts;
this.context = context;
//get user Id here.
SharedPreferences sharedPreferences;
sharedPreferences =context.getSharedPreferences(Constant.SHARED_PREF_NAME,
Context.MODE_PRIVATE);
getUserLogin = sharedPreferences.getString(Constant.ID_SHARED_PREF, "");
}
#Override
public CustomAdapterOfChat.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.items_of_chat, parent, false);
return new CustomAdapterOfChat.MyViewHolder(view);
}
#Override
public void onBindViewHolder(CustomAdapterOfChat.MyViewHolder holder, final int position) {
Log.d("USER_ID",getUserLogin);
Log.d("FRIEND_ID",contacts.get(position).getFriendId());
holder.time.setText(contacts.get(position).getDateAndTime());
if(getUserLogin.equals(contacts.get(position).getFriendId())) {
holder.msg_of_me.setVisibility(View.INVISIBLE);
holder.msg_of_them.setText(contacts.get(position).getMessage());
holder.img.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(context, UserProfileActivity.class);
intent.putExtra("id",contacts.get(position).getFriendId());
context.startActivity(intent);
}
});
Glide.with(context)
.load(Constant.BASE_URL+"y_chat/sign_up/"+contacts.get(position).getFriendName()+"/profile.png")
.error(R.drawable.error)

Exoplayer not stopping after app closes in PagerAdapter

I have problem with Exoplayer to stopping after the app is closed down, or the fragment is changed from the BottomNavigationView, I get the data from my API that is cast to a Recyclerview/Adapter that handle the data, then the data with the images and video is gettting showed with a PagerAdapter.

Phone directories in Android and problems with getting anything from them

Hi Stackoverflow community!
At first I want to say that I am a rookie in programming. Recently I tried to get photos from my phone directories by my app. It seems pretty hard to do, because I have only succeded in displaying my Camera directory, but not for example Download or Screenshots. It is really strange that Android Studio cannot resolve DOWNLOAD word in the line directories.add(filePaths.DOWNLOAD);
What is wrong with my code??? Or with me and my lack of experience...

FilePaths sorry for not formatting
public class FilePaths {
//"storage/emulated/0"
public String ROOT_DIR = Environment.getExternalStorageDirectory().getPath();
public String PICTURES = ROOT_DIR + "/Pictures";
public String CAMERA = ROOT_DIR + "/DCIM/camera";
public String FIREBASE_IMAGE_STORAGE = "photos/users/";
}

Well, the reason is simple. It's because you haven't defined the variable DOWNLOAD in the FilePaths.class. You also shouldn't point to the path like this, instead of that, use one or more of this variables:
Environment.getDataDirectory()
Environment.getDownloadCacheDirectory()
Environment.getExternalStorageDirectory()
Environment.getRootDirectory()
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_ALARMS)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_NOTIFICATIONS)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PODCASTS)
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_RINGTONES)
So your FilePaths should looks like this:
public class FilePaths {
//"storage/emulated/0"
public String ROOT_DIR = Environment.getExternalStorageDirectory().getPath();
public String DOWNLOADS = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
public String PICTURES = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
public String CAMERA = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
public String ALARMS = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_ALARMS);
public String DOCUMENTS = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS);
public String MOVIES = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES);
public String MUSIC = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC);
public String NOTIFICATIONS = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_NOTIFICATIONS);
public String PODCASTS = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PODCASTS);
public String RINGTONES = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_RINGTONES);
public String FIREBASE_IMAGE_STORAGE = "photos/users/";
}

It is in general not a good idea to use class names for your own class that are similar to java classes! Calling your class FilePaths will lead to confusion.
Change the name of your class to MyFilePaths (or something else!).
Then you can make the java file "MyFilePaths.java". Make the class public and make your variables static final:
public class MyFilePaths {
//"storage/emulated/0"
public static final String ROOT_DIR = Environment.getExternalStorageDirectory().getPath();
public static final String PICTURES = ROOT_DIR + "/Pictures";
public static final String CAMERA = ROOT_DIR + "/DCIM/camera";
public static final String FIREBASE_IMAGE_STORAGE = "photos/users/";
}
Now you can do this:
directories.add(MyFilePaths.CAMERA);
Edit
In your code you call:
FilePaths filePaths = new FilePaths();
But your FilePaths class does not have a public constructor.

How to autoplay songs in recyclerView?

I am building a music player app and have populated the recyclerView with songs from sd card. I have set the onClickListeners too. So when I click one item (song), song at that particular position starts playing. What I want is when it completes playing, I want the next song to be played automatically like in modern music players. I know I have to use OnCompletionListener, but I can't figure it out.
I'm new to Android.
Songs.java (this is a fragment):
public class Songs extends Fragment {
public static final String Broadcast_PLAY_NEW_AUDIO = "com.musicplayer.musicana.PlayNewAudio";
public static final String TAG = "Songs";
RecyclerView recyclerView;
private ArrayList<SongInfoModel> SongList = new ArrayList<SongInfoModel>();
SongAdapter songAdapter;
ScaleInAnimationAdapter alphaAdapter;
MediaPlayer mediaPlayer;
MainActivity mainActivity;
private MediaPlayerService player;
boolean serviceBound = false;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.songs_activity, container, false);
// Activity activity = getActivity();
final MainActivity activity=(MainActivity)getActivity();
recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getContext());
recyclerView.setLayoutManager(linearLayoutManager);
songAdapter = new SongAdapter(getContext(), SongList, new SongAdapter.RecyclerItemClickListener() {
#Override
public void onClickListener(SongInfoModel song, int position) {
Toast.makeText(getContext(), song.getSongName(), Toast.LENGTH_SHORT).show();
Activity activity = getActivity();
if (activity instanceof MainActivity) {
mainActivity = (MainActivity) activity;
mainActivity.setsongText(song);
((MainActivity) activity).ButtonPause();
}
prepareSong(song);
}
#Override
public void onLongClickListener(SongInfoModel song, int position) {
Toast.makeText(getContext(), "You long clicked me, thank you!", Toast.LENGTH_SHORT).show();
}
});
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.IS_MUSIC + "!=0";
Cursor cursor = getActivity().getContentResolver().query(uri, null, selection, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
String name = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
String artist = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
Long duration = cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media.DURATION));
String data = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
Long albumId = cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri albumArtUri = ContentUris.withAppendedId(sArtworkUri, albumId);
SongInfoModel s = new SongInfoModel(name, artist, null, null, null, duration, data,albumArtUri);
SongList.add(s);
} while (cursor.moveToNext());
}
cursor.close();
Collections.sort(SongList, new Comparator<SongInfoModel>() {
#Override
public int compare(SongInfoModel lhs, SongInfoModel rhs) {
return lhs.getSongName().compareTo(rhs.getSongName());
}
});
}
alphaAdapter = new ScaleInAnimationAdapter(songAdapter);
alphaAdapter.setDuration(1000);
alphaAdapter.setInterpolator(new OvershootInterpolator());
alphaAdapter.setFirstOnly(false);
recyclerView.setAdapter(alphaAdapter);
alphaAdapter.notifyDataSetChanged();
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
togglePlay(mp);
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mediaPlayer) {
}
});
activity.setOnSongClickListener(new MainActivity.OnSongCickListener() {
#Override
public void onsongClicked() {
if(mediaPlayer.isPlaying() && mediaPlayer!=null ){
mediaPlayer.pause();
activity.ButtonPlay();
} else {
mediaPlayer.start();
activity.ButtonPause();
}
}
});
return view;
}
private void prepareSong(SongInfoModel song) {
mediaPlayer.reset();
try {
mediaPlayer.setDataSource(song.getData());
mediaPlayer.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}
}
private void togglePlay(MediaPlayer mp) {
if (mp.isPlaying()) {
mp.stop();
mp.reset();
} else {
mp.start();
}
}
SongAdapter.java(recyclerVIews adapter):
public class SongAdapter extends RecyclerView.Adapter<SongAdapter.SongHolder> {
ArrayList<SongInfoModel> SongList = new ArrayList<>();
Context context;
private RecyclerItemClickListener listener;
public SongAdapter(Context context, ArrayList<SongInfoModel> SongList, RecyclerItemClickListener listener) {
this.context = context;
this.SongList = SongList;
this.listener = listener;
}
#Override
public SongAdapter.SongHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.row_song, parent, false);
return new SongHolder(view);
}
#Override
public void onBindViewHolder(final SongAdapter.SongHolder holder, final int position) {
final SongInfoModel songInfoModel = SongList.get(position);
if(songInfoModel!= null){
holder.songName.setText(songInfoModel.SongName);
holder.artistName.setText(songInfoModel.ArtistName);
holder.duration.setText(String.valueOf(songInfoModel.duration));
String duration = Utility.convertDuration(songInfoModel.getDuration());
holder.duration.setText(duration);
Picasso.with(context).load(songInfoModel.getAlbumID()).placeholder(R.drawable.ic_launcher).into(holder.iv_artwork);
holder.bind(songInfoModel, listener);
}
}
#Override
public int getItemCount() {
return SongList.size();
}
public class SongHolder extends RecyclerView.ViewHolder {
TextView songName;
TextView artistName;
TextView duration;
private ImageView iv_artwork;
public SongHolder(View itemView) {
super(itemView);
songName = (TextView)itemView.findViewById(R.id.SongName);
artistName= (TextView)itemView.findViewById(R.id.ArtistName);
duration = (TextView) itemView.findViewById(R.id.duration);
iv_artwork = (ImageView) itemView.findViewById(R.id.iv_artwork);
}
public void bind(final SongInfoModel songInfoModel, final RecyclerItemClickListener listener) {
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
listener.onClickListener(songInfoModel, getLayoutPosition());
}
});
itemView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View view) {
listener.onLongClickListener(songInfoModel, getLayoutPosition());
return true;
}
});
}
}
public interface RecyclerItemClickListener{
void onClickListener(SongInfoModel song, int position);
void onLongClickListener(SongInfoModel song, int position);
}
}

You can use the Completion Listener of Media Player like this
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
//pass the path of the new song here
}
});

I just found out the solution! It is easy!
In SongAdapter.java : Add this,
private int selectedPosition;
public void setSelectedPosition(int selectedPosition) {
this.selectedPosition = selectedPosition;
}
public int getSelectedPosition() {
return selectedPosition;
}
In Songs.java: Add this,
private void changeSelectedSong(int index){
songAdapter.notifyItemChanged(songAdapter.getSelectedPosition());
currentIndex = index;
songAdapter.setSelectedPosition(currentIndex);
songAdapter.notifyItemChanged(currentIndex);
}
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
if(currentIndex + 1 < SongList.size()){
SongInfoModel next = SongList.get(currentIndex + 1);
changeSelectedSong(currentIndex+1);
prepareSong(next);
mainActivity.setsongText(next);
}else{
SongInfoModel next = SongList.get(0);
changeSelectedSong(0);
prepareSong(next);
mainActivity.setsongText(next);
}
}
});
And call changeSelectedSong(position) in onClick.
