Android Recyclerview MediaPlayer上一个项目声音停止，单击新项目后释放 [英] Android Recyclerview MediaPlayer previous Item sound stop, release after new one is clicked
问题描述
在我的应用程序中，我有recyclerview物品，并且每个物品在我单击时都会播放声音. 问题是，当我单击几个项目时，它们都在同一时间播放声音，直到它们完成为止. 假设我单击了10个项目，所有10个播放声音同时出现，并且一段时间后应用程序崩溃了，并且出现以下错误: E/MediaPlayer:错误(1，-19). 通过使用以下代码实现自动发布，我避免了应用崩溃:
In my app i have recyclerview items, and each item play sound when i click it. Problem is that when i click few items, they all play sounds in the same time until they finish. Lets say i click 10 items, all 10 play sounds in the same time and after some time app get crashed and i get this error: E/MediaPlayer: error (1, -19). I avoid app crashing by implementing automatic release with this code:
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mediaPlayer.release();
}
});
但这不是我想要的，同时听到很少的声音很烦人.我想要的是在单击新声音时停止以前的声音，我试图使Mediaplayer停止并释放，但没有成功.
But that's not what i want, it is annoying to hear few sounds in the same time. What i want is to stop previous sound when i click new one, i try to implent mediaplayer stop and release, but without success.
这是Google Play中的应用，因此您可以自己检查: https://play.google.com/store/apps/details?id=org.pero.androidd.animalSoundsQuiz

这是我播放声音的适配器代码.在这段代码中，有一部分MediaPlayer.OnCompletionListener()，在声音播放完后，我会释放声音，以免 E/MediaPlayer:错误(1，-19)错误，但这不是我想要的应用程序.我想在单击新声音后停止上一个声音.
Here is my Adapter code where i play sounds. In this code there is part MediaPlayer.OnCompletionListener() where i release sound after sound finish to aviod E/MediaPlayer: error (1, -19) error, but that is not what i want in my app. I want to stop previous sound after i click new one.

我找到了解决方案，我不知道这是最聪明的方法，但是对我来说很好:
I find solution, i do not know is this the smartest way to do it but it works for me fine:
我所做的是我使静态媒体播放器可变，因此我可以从ViewHolder访问媒体播放器并在单击新声音时停止播放先前的声音.希望对您有所帮助.
What i done is that i made static media player variable and this way i can access to media player from ViewHolder and stop previous sound when i click new one. Hope it helps.
这是完整的代码:
public class ZivotinjeAdapter extends RecyclerView.Adapter<ZivotinjeAdapter.ViewHolder> {
private static MediaPlayer mediaPlayer; //THIS IS THE CHANGE I DONE
@Override
public ZivotinjeAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
// Inflate the custom layout
View contactView = inflater.inflate(R.layout.item_zivotinje, parent, false);
// Return a new holder instance
ViewHolder viewHolder = new ViewHolder(contactView);
return viewHolder;
}
@Override
public void onBindViewHolder(ZivotinjeAdapter.ViewHolder viewHolder, int position) {
Zivotinje zivotinjeIme = mZivotinje.get(position);
// Set item views based on the data model
TextView textView = viewHolder.nameTextView;
textView.setText(zivotinjeIme.getmAnimal_name());
//THIS IS WHERE I HANDALE IMAGE VIEW. Using glide for images
ImageView slika_source = viewHolder.imageView;
Glide.with(slika_source.getContext())
.load((Integer) zivotinjeIme.getmAnimal_slika())
.into(slika_source);
viewHolder.setItem(mZivotinje.get(position));
}
@Override
public int getItemCount() {
return mZivotinje.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public ImageView imageView;
public TextView nameTextView;
private Zivotinje mItem;
public void setItem(Zivotinje item) {
this.mItem = item;
}
public ViewHolder(final View itemView) {
super(itemView);
nameTextView = (TextView) itemView.findViewById(R.id.zivotinjaIme_id);
imageView = (ImageView) itemView.findViewById(R.id.slika_id);
//handaling clicks
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mediaPlayer != null && mediaPlayer.isPlaying()) {
mediaPlayer.stop();
mediaPlayer.reset();
mediaPlayer.release();
mediaPlayer = null;
}
mediaPlayer = MediaPlayer.create(v.getContext(), mItem.getmSound());
mediaPlayer.start();
}
});
}
}
private List<Zivotinje> mZivotinje;
public ZivotinjeAdapter(List<Zivotinje> animals) {
mZivotinje = animals;
}
}
推荐答案
您首先必须检查是否已经在播放声音，如果有，则在用户决定开始新声音时应停止播放.
You first have to check if there is a sound that is already playing and if there is, you should stop it when the user decides to start a new sound.
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mediaplayer.isPlaying ()) {
if (mediaplayer != null){
mediaplayer.stop ();
}
} else {
if (mediaplayer != null) {
mediaplayer.start ();
}
}
}
});
在setOnCompletionListner中，如果用户听了整个声音片段，则释放声音.
In setOnCompletionListner you release the sound if the user listens to the whole sound clip.
mediaplayer. setOnCompletionListner (new MediaPlayer.OnCompletionListner () {
public void OnCompletion (MediaPlayer mediaplayer) {
mediaplayer.release ();
}
});
