I made a simple class that handles everything related to sound. Has an add, play, stop, release and releaseAll. How it works is that you have to add a song and then call play passing the name of the song you added. Anytime you need to stop, just call the stop function and pass the song's name as parameter and it should stop. My issue is that it isn't stopping even though it goes through stop()
.
Sound class:
public class Sound
{
private Map<String, MediaPlayer> songs = new HashMap<String, MediaPlayer>();
private MediaPlayer currentlyPlayingSong;
public Sound() {}
public void Add(int songId, String songName, Context context)
{
MediaPlayer song = MediaPlayer.create(context, songId);
songs.put(songName, song);
}
public void Play(String name, boolean shouldLoop)
{
MediaPlayer songToPlay = songs.get(name);
if ( songToPlay != currentlyPlayingSong && songToPlay != null)
{
currentlyPlayingSong = songToPlay;
currentlyPlayingSong.start();
currentlyPlayingSong.setLooping(shouldLoop);
}
}
public void Stop(String name)
{
MediaPlayer songToStop = songs.get(name);
if (songToStop != null)
{
songToStop.setLooping(false);
songToStop.stop();
}
}
public void Release(String name)
{
songs.get(name).release();
}
public void ReleaseAll()
{
LinkedList<MediaPlayer> _songs;
_songs = (LinkedList)songs.values();
for (int i = 0; i < _songs.size(); i++)
{
_songs.get(i).release();
}
}
}
On the activity's OnCreate
I call Add
then Play
. Everything is fine until I try to call Stop
from a fragment. Runs without any errors or exceptions, it simply doesn't stop.
Activity:
public class Main extends ActionBarActivity
{
private Sound sound = new Sound();
private static boolean isSoundOn = true;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
isSoundOn = true;
sound.Add(R.raw.drajamainmenueddited, "mainMenuSong", this);
//endregion
//Hide upper action bar
getSupportActionBar().hide();
if (isSoundOn)
sound.Play("mainMenuSong", true);
}
public void SetIsSoundOn(Boolean isOn)
{
isSoundOn = isOn;
}
public boolean GetIsSoundOn()
{
return isSoundOn;
}
public Sound GetSoundObj()
{
return sound;
}
}
Fragment:
public class MainMenuFragment extends Fragment {
private ImageButton soundImgBtn;
private FragmentConfig fragmentConfig;
public MainMenuFragment()
{
fragmentConfig = new FragmentConfig();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
//region Initiators
View view = inflater.inflate(R.layout.fragment_main_menu, container, false);
soundImgBtn = (ImageButton)view.findViewById(R.id.soundImgBtn);
//endregion
//region Listeners
soundImgBtn.setOnClickListener(
new View.OnClickListener()
{
@Override
public void onClick(View v)
{
SoundImgBtnClick(v);
}
}
);
//endregion
//Changes audio img
if (((Main)getActivity()).GetIsSoundOn())
soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode_off);
else
soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode);
// Inflate the layout for this fragment
return view;
}
private void SoundImgBtnClick(View v)
{
//if sound is on and clicked, turn off
if (((Main)getActivity()).GetIsSoundOn())
{
((Main)getActivity()).SetIsSoundOn(false);
((Main)getActivity()).GetSoundObj().Stop("mainMenuSong");
soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode);
}
else
{
((Main)getActivity()).SetIsSoundOn(true);
((Main)getActivity()).GetSoundObj().Play("mainMenuSong", true);
soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode_off);
}
}
}
What I'm trying to do is emulate a mute button. Once clicked all sounds should be muted.
This is pretty much all I've coded, so far.
Cheers.
I suspect you're using different instances of MediaPlayer. You are allowed to do that BUT you must stop the song within the same instance. About the code in Add():
MediaPlayer song = MediaPlayer.create(context, songId);
In Stop():
MediaPlayer songToStop = songs.get(name)
Note :
song
needs to be declared on a higher scope for you to access it and to stop the song.试试 songToStop.release() 代替
Got it to stop. My class had to be able to handle one song at a time and many fx at the same time. This is what I came up with.
Sound:
public class Sound
{
private static MediaPlayer currentlyPlayingSong,
currentlyPlayingFX;
public Sound() {}
public void PlayFX(int fxId, Context context, boolean shouldLoop)
{
MediaPlayer fx = MediaPlayer.create(context, fxId);
if (currentlyPlayingFX != fx)
{
StopFX();
currentlyPlayingFX = fx;
currentlyPlayingFX.start();
currentlyPlayingFX.setLooping(shouldLoop);
}
}
public void PlaySong(int songId, boolean shouldLoop, Context context)
{
MediaPlayer song = MediaPlayer.create(context, songId);
if (currentlyPlayingSong != song)
{
StopSong();
currentlyPlayingSong = song;
currentlyPlayingSong.start();
currentlyPlayingSong.setLooping(shouldLoop);
}
}
public void StopFX()
{
if (currentlyPlayingFX != null)
{
currentlyPlayingFX.stop();
currentlyPlayingFX.release();
currentlyPlayingFX = null;
}
}
public void StopSong()
{
if (currentlyPlayingSong != null)
{
currentlyPlayingSong.stop();
currentlyPlayingSong.release();
currentlyPlayingSong = null;
}
}
}
This is was based of what @The Original Android answered. Keep it on a single instance.
Thanks for the help.
