Android如何在Recycleview中启动新声音时停止媒体播放器

Question

我试图找到解决方案但找不到它。

我的问题是我在recycleview中有很多项目。每个项目都有图像，当我点击该图像时，它会启动该图像的声音。 问题是，当我开始新声音时，前一个声音不会停止，它会继续播放，直到声音结束。点击15后，20个声音应用程序崩溃，我收到此错误消息：

E / MediaPlayer：错误（1，-19）

当我点击新声音时，我需要实现释放和停止前一个声音。我试图找到解决方案，但我找不到它用于recycleview。

这是我的适配器代码：

import android.content.Context;
import android.media.MediaPlayer;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import com.bumptech.glide.Glide;

import java.util.List;


public class ZivotinjeAdapter extends RecyclerView.Adapter<ZivotinjeAdapter.ViewHolder> {

    @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);

            
//this is click event for each item and here i play sound
            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    
                    MediaPlayer mediaPlayer = MediaPlayer.create(v.getContext(), mItem.getmSound());
                    mediaPlayer.start();

                }
            });

        }


    }

    private List<Zivotinje> mZivotinje;

    public ZivotinjeAdapter(List<Zivotinje> animals) {
        mZivotinje = animals;
    }




}

添加：

@Override
public void onClick(View v) {
stopPlaying();  <-------            
MediaPlayer mediaPlayer =   MediaPlayer.create(v.getContext(),mItem.getmSound());
mediaPlayer.start();}

和此：

.......

public ZivotinjeAdapter(List<Zivotinje> animals) {
    mZivotinje = animals;
}

private void stopPlaying() {

    if(mediaPlayer != null && mediaPlayer.isPlaying())
    {
        mediaPlayer.stop();
        mediaPlayer.reset();
        mediaPlayer.release();
        mediaPlayer = null;
    }
}
