It's not displaying MediaPlayer progress
also, It is playing multiple songs at the same time
solution needed for 2 bugs
Here is a screenshot of that app
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.DividerItemDecoration;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.Button;
import android.widget.SeekBar;
import java.io.IOException;
import java.util.ArrayList;
public class MainActivity2 extends AppCompatActivity {
private ArrayList<SongInfo> _songs = new ArrayList<SongInfo>();
RecyclerView recyclerView;
SeekBar seekBar;
SongAdapter songAdapter;
MediaPlayer mediaPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
seekBar = (SeekBar) findViewById(R.id.seekBar);
SongInfo s = new SongInfo("Cheap Thrills", "sia", "http://176.126.236.250/33Mmt/music/hindi/movies/new/oh_my_god/Go-Go-Govinda_(webmusic.in).mp3");
_songs.add(s);
s = new SongInfo("Cheap Thrills", "sia", "http://176.126.236.250/33Mmt/music/hindi/movies/new/oh_my_god/Go-Go-Govinda_(webmusic.in).mp3");
_songs.add(s);
songAdapter = new SongAdapter(this, _songs);
recyclerView.setAdapter(songAdapter);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
DividerItemDecoration dividerItemDecoration = new DividerItemDecoration(recyclerView.getContext(),
linearLayoutManager.getOrientation());
recyclerView.addItemDecoration(dividerItemDecoration);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setAdapter(songAdapter);
songAdapter.setOnItemClickListener(new SongAdapter.OnItemClickListener() {
#Override
public void onItemClick(final Button b, View view, SongInfo obj, int position) {
try {
if (b.getText().toString().equals("stop")) {
b.setText("Play");
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}else {
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(obj.getSongUrl());
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
b.setText("stop");
}
});
}
} catch (IOException e) {
}
}
});
}
}
this is my song adapter code -:
package com.a03.dip.kaliprasadbengalisongs;
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
import java.util.ArrayList;
public class SongAdapter extends RecyclerView.Adapter<SongAdapter.SongHolder> {
ArrayList<SongInfo> _songs;
Context context;
OnItemClickListener mOnItemClickListener;
SongAdapter(Context context, ArrayList<SongInfo> songs) {
this.context = context;
this._songs = songs;
}
public interface OnItemClickListener {
void onItemClick(Button b ,View view, SongInfo obj, int position);
}
public void setOnItemClickListener(final OnItemClickListener mItemClickListener) {
this.mOnItemClickListener = mItemClickListener;
}
#Override
public SongHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View myView = LayoutInflater.from(context).inflate(R.layout.row_song,viewGroup,false);
return new SongHolder(myView);
}
#Override
public void onBindViewHolder(final SongHolder songHolder, final int i) {
final SongInfo c = _songs.get(i);
songHolder.songName.setText(_songs.get(i).songName());
songHolder.artistName.setText(_songs.get(i).artistName());
songHolder.btnAction.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mOnItemClickListener != null) {
mOnItemClickListener.onItemClick(songHolder.btnAction,v, c, i);
}
}
});
}
#Override
public int getItemCount() {
return _songs.size();
}
public class SongHolder extends RecyclerView.ViewHolder {
TextView songName,artistName;
Button btnAction;
public SongHolder(View itemView) {
super(itemView);
songName = (TextView) itemView.findViewById(R.id.tvSongName);
artistName = (TextView) itemView.findViewById(R.id.tvArtistName);
btnAction = (Button) itemView.findViewById(R.id.btnPlay);
}
}
}
and here is songInfo class -----
package com.a03.dip.kaliprasadbengalisongs;
import android.media.MediaPlayer;
public class SongInfo {
public String songName ,artistName,songUrl;
public SongInfo() {
}
public SongInfo(String songName, String artistName, String songUrl) {
this.songName = songName;
this.artistName = artistName;
this.songUrl = songUrl;
}
public String songName() {
return songName;
}
public String artistName() {
return artistName;
}
public String getSongUrl() {
return songUrl;
}
}

Answer 1

you have to use seekbar listener on ur activity.
seekBar.setOnSeekBarChangeListener(new >SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int >progress,
boolean fromUser) {
if (fromUser) {
mPlayer.seekTo(progress);
}
}
