我正在尝试获取片段中 mp3 文件的资源 ID，但我不知道如何执行此操作。以下代码为资源 ID 返回零。是的，该文件在原始目录中。（我正在使用 ActionBarSherlock，但我不确定这是否重要。） 

public class NavigationFragment extends SherlockFragment {

  @Override
  public View onCreateView(LayoutInflater inflater,
                         ViewGroup container,
                         Bundle savedInstanceState) {
    View nav =inflater.inflate(R.layout.navigation, container, false);
  } 

  @Override
  public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    try {
        int resourceID = getResources().getIdentifier("bell01", "raw", "com.webnation.yogatest");
        Log.d("We're Here", "resourceID =" + resourceID);

        bell = MediaPlayer.create(getActivity(), resourceID);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        Log.d("Exception", e.toString());
    }
  } //onActivityCreated

}

清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.webnation.yogatest"
android:versionCode="1"
