Question

让我解释一下：

我有一个名为“Sounds”的文件夹，还有一些.ogg文件可以播放。
我使用Environment.getExternalStorageDirectory().getAbsolutePath() + mySoundsPath;获得了文件夹路径。
我从该文件夹中获取了所有列表并将其保存到数组：List<String> soundList;

我的问题是：

如何调用我创建的soundList的声音，这样他们都可以播放？
是否需要解码（如图像，解码为Bitmap）??

对不起我的语法。提前谢谢。

使用以下链接作为参考 http://developer.android.com/reference/android/media/MediaPlayer.html

您也可以尝试使用小代码示例

public void play（String path）{ 计数++; playFile =路径;

            //showNotification();
        new NotificationPanel(activity);


            if(mediaPlayer!=null && mediaPlayer.isPlaying()){
                Log.d("*****begin*****", "playing");
                stopPlaying();
                 Log.d("*****begin*****", "stoping");
              } else{
                 Log.d("*****begin*****", "nothing");
              }


            Uri myUri1 = Uri.parse(path);
            mediaPlayer = new MediaPlayer();
            mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

            try {
                mediaPlayer.setDataSource(activity, myUri1);            
            } catch (IllegalArgumentException e) {
                Toast.makeText(activity, "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (SecurityException e) {
                Toast.makeText(activity, "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (IllegalStateException e) {
                Toast.makeText(activity, "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                e.printStackTrace();
            }

            try {
                mediaPlayer.prepare();
            } catch (IllegalStateException e) {
                Toast.makeText(activity, "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                Toast.makeText(activity, "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
            }
            mediaPlayer.start();

        }

        private void stopPlaying() { 
            if (mediaPlayer != null) {
                mediaPlayer.stop();
                mediaPlayer.release();
                mediaPlayer = null;
           } 
        }

使用MediaPlayer播放SDCard的声音？
