Pass songs from Arraylist to another activity

Question

I want to create a very simple app that shows a list of songs and when clicking on song it opens a new Activity to show the playing statue of the song, I almost created it all but when I click on play button it doesn't play.

First activity:

    private Button buttonPlayStop;
    private MediaPlayer mMediaPlayer;
    private Context context;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.listview);

    final ArrayList<Songs> songslist = new ArrayList<Songs>();
    songslist.add(new Songs("hhhhh", "cHU CHU ", R.drawable.mimi, R.raw.hhh));
    songslist.add(new Songs("hhhh", "cHU CHU ", R.drawable.jes1s, R.raw.hhh));
    songslist.add(new Songs("hhhh", "cHU CHU ", R.drawable.matt, R.raw.hhh));
    songslist.add(new Songs("hhhhh", "cHU CHU ", R.drawable.freind, R.raw.hhh));
    songslist.add(new Songs("hhhhh", "cHU CHU ", R.drawable.joe, R.raw.hhh));
    songslist.add(new Songs("hhhhh ", "cHU CHU ", R.drawable.bada, R.raw.hhh));
    songslist.add(new Songs("hhhhh", "cHU CHU ", R.drawable.abby, R.raw.hhh));

    final SongsAdapter adapter = new SongsAdapter(this, songslist);

    final ListView listView = (ListView) findViewById(R.id.listview);

    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new   AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> adapterView, View  view, int position, long l) {
            Songs song = songslist.get(position);

            Intent anotherActivityIntent = new  Intent(FunActivity.this, playingActivity.class);
            anotherActivityIntent.putExtra("songs",songslist);
            startActivity(anotherActivityIntent);

        }
    });

Playing activity:

    public class playingActivity extends FunActivity {
    private MediaPlayer mMediaPlayer;
    private Button buttonPlayStop;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_playing);
    ArrayList<Songs> songs =                    getIntent().getParcelableArrayListExtra("Songs");
    buttonPlayStop = (Button)findViewById(R.id.ButtonPlayStop);
    buttonPlayStop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

           mMediaPlayer.start();
        }
    });

   }

Answer 1

Not tested but..

First activity:

Change
anotherActivityIntent.putExtra("songs",songslist);

to
anotherActivityIntent.putExtra("songs",song);

Playing activity:

Change
ArrayList<Songs> songs = getIntent().getParcelableArrayListExtra("Songs");

to

Songs songs = getIntent().getParcelableExtra("songs");

And you need to add some codes in Playing activity to
- Translate Songs to it's path (maybe better to have the path in Songs class)
- Set the path to mMediaPlayer (Please see MediaPlayer.setDataSource(string))
- Call mMediaPlayer.prepare()
- Then call mMediaPlayer.start()

NB: Calling mMediaPlayer.start() in onClickListener.onClick() which is set to buttonPlayStop in your code seems to be a typo.

Please refer to MediaPlayer.StateDiagram or MediaPlayer developer guide for farther information.
