Andreas answer is the right way to do this but that code does not get the absolute file path. This causes the mMediaPlayer.prepare(); to throw IOException: Prepare failed. status=0x1.
Here is the code to get the file path along with the file name:
private String[] mAudioPath;
private MediaPlayer mMediaPlayer;
private String[] mMusicList;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mMediaPlayer = new MediaPlayer();
ListView mListView = (ListView) findViewById(R.id.listView1);
mMusicList = getAudioList();
ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, mMusicList);
mListView.setAdapter(mAdapter);
mListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
try {
playSong(mAudioPath[arg2]);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
private String[] getAudioList() {
final Cursor mCursor = getContentResolver().query(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
new String[] { MediaStore.Audio.Media.DISPLAY_NAME, MediaStore.Audio.Media.DATA }, null, null,
"LOWER(" + MediaStore.Audio.Media.TITLE + ") ASC");
int count = mCursor.getCount();
String[] songs = new String[count];
String[] mAudioPath = new String[count];
int i = 0;
if (mCursor.moveToFirst()) {
do {
songs[i] = mCursor.getString(mCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DISPLAY_NAME));
mAudioPath[i] = mCursor.getString(mCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA));
i++;
} while (mCursor.moveToNext());
}
mCursor.close();
return songs;
}
Now that we have the absolute path, we don't need to get the path again. So:

安德烈亚斯的答案是执行此操作的正确方法，但该代码无法获取绝对文件路径。
这会导致
mMediaPlayer.prepare();抛出IOException：准备失败。状态=0x1。下面是获取文件路径和文件名的代码：
现在我们有了绝对路径，我们不需要再次获取路径。所以：
使用：
而不是：
请确保在列表视图 OnItemClickListener 中
。要仅获取曲目的标题（看起来比带有扩展名的整个文件名更优雅），请使用：
而不是：

This causes the
mMediaPlayer.prepare();to throwIOException: Prepare failed. status=0x1.Here is the code to get the file path along with the file name:

Make sure to use:
instead of:
in the listview OnItemClickListener.
To get only the title of the track (Looks more elegant than the whole file name with extension) use:
instead of:
我不完全确定是什么原因导致了您提到的问题，但请尝试此代码。
I'm not entirely sure exactly what causes the problems you mention, but try this code.
那里的代码有超级错误。
getView没有任何意义。 gc() 在那里做什么？！所有 moveToPosition() 调用是怎么回事？这是重写的代码
The code there is super-buggy.
The
getViewdoesn't make any sense. What is that gc() doing there?! What's with the all moveToPosition() calls.Here's the code rewritten
试试这个代码
try this code
