如何直接从res / raw文件夹播放音频文件？

Question

我在res/raw文件夹中有多个音频文件。我显示了包含音频文件名的ListView。当用户选择进入ListView时，我想播放相应的音频文件。我使用了setDataSource(path)，但播放时显示错误。如何直接从该文件夹播放音频文件？还是还有其他方法？

Answer 1

将此代码添加到onItemClickListener中。

listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {                 
                TextView txtView=(TextView)view.findViewById(R.id.txt_view);
                String fname=txtView.getText().toString().toLowerCase();

                                int resID=getResources().getIdentifier(fname, "raw", getPackageName());

                              MediaPlayer mediaPlayer=MediaPlayer.create(this,resID);
                    mediaPlayer.start();
            }
        });

尝试从原始:::>播放此游戏]

MediaPlayer mPlayer2;
mPlayer2= MediaPlayer.create(this, R.raw.bg_music_wav);
        mPlayer2.start();
清单文件中的权限::

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
更新：：

public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {     
  MediaPlayer mPlayer2;
if(position==1)
{
    mPlayer2= MediaPlayer.create(this, R.raw.song1);
            mPlayer2.start();
}else it() .....
}

mVideoView = (VideoView) findViewById(R.id.Video_FrontPage);
uri = Uri.parse("android.resource://com.urPackageName/" + R.raw.welcom_video);
mVideoView.setVideoURI(uri);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
mVideoView.start();

Answer 4

 lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> parent, View view,
          int position, long id) {

          // selected item 
          String product = ((TextView) view).getText().toString();

          int [] resID= {R.raw.sound1,R.raw.sound2,R.raw.sound3};
        MediaPlayer mediaPlayer=MediaPlayer.create(this,resID[position]);

          mediaPlayer.start();
          // sending data to new activity


      }
    });
}

要播放原始文件夹中的音频，请调用此方法。就我而言，我的文件名是notificaion.mp3
