使用毕加索显示音乐的专辑封面 [英] displaying album art for music using picasso

问题描述

您好，我需要使用 Picasso 有效地显示音乐文件的相册艺术.我已经在我的应用程序中配置了毕加索.但是我无法从内部存储中显示音乐文件的专辑封面.

Hello I need to display album art for music files efficiently using Picasso. I already configured picasso in my app. But I am not able to display album art from internal storage for music files.

我尝试了这段代码，但是它不起作用意味着没有错误，但是它什么也没显示.

I tried this code but it's not working means no error but it doesn't display anything.

1. 使用uri:

1. Using uri :

cursor = getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Audio.AudioColumns.DURATION + ">0", null, sortOrder);

cursor.moveToFirst();

a = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));

l = Long.parseLong(a);
final Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, l);

Picasso.with(MainActivity.this).load(uri).into(iv);

使用新文件:

Using new File :

cursor = getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Audio.AudioColumns.DURATION + ">0", null, sortOrder);

cursor.moveToFirst();

a = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));

Picasso.with(this)
       .load(Uri.parse("file://"+a))
       .error(R.drawable.color_music_player_logo)
       .into(iv);

推荐答案

为毕加索的图像提供绝对路径，如下所示:

Give Picasso absolute path to your image like this:

String name = "image.jpeg";
String dir = Environment.getExternalStorageDirectory().getAbsolutePath();
Picasso.with(context).load(new File(dir + File.separator + name)).into(iv);

或者您可以使用filechooser，以便选择要加载的图像或显示图像列表，然后onclick为您加载图像....

or you can use filechooser so you can select which image to load or show list of images and onclick loads an image for you ....
