添加MP3到ContentResolver的 [英] Adding mp3 to the ContentResolver
问题描述
我知道,从你的应用程序下载的MP3后,你需要将其添加到 ContentResolver的
来看看它的音乐播放器。我这样做有以下code:
I know that after downloading an mp3 from your app you need to add it to the ContentResolver
to see it on the music player. I am doing it with the following code:
private void addFileToContentProvider() {
ContentValues values = new ContentValues(7);
values.put(Media.DISPLAY_NAME, "display_name");
values.put(Media.ARTIST, "artist");
values.put(Media.ALBUM, "album");
values.put(Media.TITLE, "Title");
values.put(Media.MIME_TYPE, "audio/mp3");
values.put(Media.IS_MUSIC, true);
values.put(Media.DATA, pathToFile);
context.getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
}
我的问题是,我愿意以避免将 DISPLAY_NAME
,艺术家
, ALBUM
,标题
的手。
有没有办法告诉机器人从文件中做呢?我已经使用刚 values.put(Media.DATA,pathToFile);
,但它没有将它添加到播放
Is there a way to tell Android to do it from the file? I've already used just values.put(Media.DATA, pathToFile);
but it's not adding it to the player.
有没有办法迫使它扫描SD音乐的主题?
Is there a way to force the thread that scans the sd for music?
推荐答案
首先尝试添加这样的:
values.put(MediaStore.Audio.Media.IS_MUSIC, true);
那么试试这个:
Then try this:
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://"+path+filename)));
如果还是不行,请尝试以下:
If that doesn't work, try this:
public MediaScannerConnection mScanner = null;
public void reScan(String filename){
final String name = filename;
mScanner = new MediaScannerConnection(THE_NAME_OF_YOUR_ACTIVITY.this, new MediaScannerConnection.MediaScannerConnectionClient() {
public void onMediaScannerConnected() {
mScanner.scanFile(name, null);
}
public void onScanCompleted(String path, Uri uri) {
if (path.equals(name)) {
mScanner.disconnect();
}
}
});
mScanner.connect();
}
添加一个mp3后,只要调用此方法,需要的文件名作为输入。
After adding an mp3, just call this method which takes the file name as the input.
,并确保您的活动的名称替换THE_NAME_OF_YOUR_ACTIVITY。
And make sure to replace THE_NAME_OF_YOUR_ACTIVITY with the name of your activity.
