Question

我有以下代码：

animalGallery.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                    @Override
                    public void onItemClick(AdapterView<?> arg0, View arg1,
                            int arg2, long arg3) {
                        // TODO Auto-generated method stub

                        animalView.setImageResource(symbolIds[arg2]);

String imageName = getResources().getResourceEntryName(
                            symbolIds[arg2]);

                    Toast.makeText(getApplicationContext(), imageName,
                            Toast.LENGTH_LONG).show();

                    int audioId = getResources().getIdentifier(
                            imageName, null, getPackageName());


                        try {
                            MediaPlayer mp = MediaPlayer.create(
                                getApplicationContext(), audioId);

                        mp.start();

                        } catch (Exception e) {
                            Toast.makeText(getApplicationContext(),
                                    "not working", Toast.LENGTH_LONG).show();
                        }

                    }
                });

当我运行此代码时，我得到了正确的imageName。

我的所有mp3文件都在raw文件夹中。

我想根据imagename播放mp3文件。

suppose imageName='hardweell" then the hardweell.mp3 is must be play

媒体没有播放。它每次都会被捕获。

那么我该如何解决这个问题？

以下是文件崩溃的日志：

如果文件位于raw文件夹内，则通过使用R.raw.<filename>传递视频ID来准备媒体播放器：

int audioId = getResources().getIdentifier(imageName, null, getPackageName());
MediaPlayer mp = MediaPlayer.create(getApplicationContext(),audioId);

媒体不是从原始文件夹播放
