我正在尝试从移动设备获取所有音频文件，但我能够一次获得一个SD_card文件或内部存储文件，但我如何使用mediastore获取内部和外部文件信息以及我将进行哪些更改do .by将EXTERNAL_CONTENT_URI更改为INTERNAL_CONTENT_URI我能够获取内部文件，但是如何同时获取两者。我的音频转发方法
private void parseAllAudio(String type) {
try {
String TAG = "Audio";
Cursor cur = getContentResolver().query(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, null, null,
null);
if (cur == null) {
// Query failed...
Log.e(TAG, "Failed to retrieve music: cursor is null :-(");
}
else if (!cur.moveToFirst()) {
// Nothing to query. There is no music on the device. How boring.
Log.e(TAG, "Failed to move cursor to first row (no query results).");
}else {
Log.i(TAG, "Listing...");
// retrieve the indices of the columns where the ID, title, etc. of the song are
// add each song to mItems
do {
int artistColumn = cur.getColumnIndex(MediaStore.Audio.Media.ARTIST);
int titleColumn = cur.getColumnIndex(MediaStore.Audio.Media.TITLE);
int albumColumn = cur.getColumnIndex(MediaStore.Audio.Media.ALBUM);
int durationColumn = cur.getColumnIndex(MediaStore.Audio.Media.DURATION);
int idColumn = cur.getColumnIndex(MediaStore.Audio.Media._ID);
int filePathIndex = cur.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
Log.i(TAG, "Title column index: " + String.valueOf(titleColumn));
Log.i(TAG, "ID column index: " + String.valueOf(titleColumn));
Log.i("Final ", "ID: " + cur.getString(idColumn) + " Title: " + cur.getString(titleColumn) + "Path: " + cur.getString(filePathIndex));
MediaFileInfo audio = new MediaFileInfo();
audio.setFileName(cur.getString(titleColumn));
audio.setFilePath(cur.getString(filePathIndex));
audio.setFileType(type);
mediaList.add(audio);
} while (cur.moveToNext());
}
} catch (Exception e) {
e.printStackTrace();
}
}
