Question

我有一个Android应用，我想播放不同的声音。我的代码工作正常，但播放了一些声音后便停止播放更多声音。我的点击侦听器位于ListView中，因此会循环播放不同的声音。我认为问题是由于创建和停止造成的，但我不知道如何解决它？

任何人都可以帮助我的代码吗？

 MediaPlayer mp;
 holder.alphabetSound.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(mp != null && mp.isPlaying()) {
                mp.stop();
            }
            mp = MediaPlayer.create(activity,sound[index]));
            mp.start();
        }
    });

Answer 1

 private void startMP(final Context context){
        if(mp == null){
            mp = MediaPlayer.create( context, R.raw.ringtone);
            mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                @Override
                public void onCompletion(MediaPlayer mediaPlayer) {
                    stopMP(context);
                }
            });
        }
        mp.start();
        mp.setLooping(true);
    }

    private void stopMP(Context context) {
        if(mp != null) {
            mp.release();
            mp = null;
            Toast.makeText(context , "song is stopped " , Toast.LENGTH_SHORT).show();
        }
    }

根据需要使用此方法。如您所想，问题出在创建和停止过程中。我认为，如果您这样做，将会很有帮助。
