Question

在Android中如何獲取音頻文件w enter image description here第i個縮略圖進入列表視圖？

Answer 1

這裏從存儲 -

public class SongsManager{ 
// SDCard Path 

private ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>(); 
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0"; 
Cursor cursor; 
String[] projection = { MediaStore.Audio.Media.ALBUM_ID, 
     MediaStore.Audio.Media.DISPLAY_NAME, MediaStore.Audio.Media.DATA,MediaStore.Audio.Media.ARTIST, 
     MediaStore.Audio.Media.DURATION 

}; 

@SuppressWarnings("deprecation") 
public void getCursor(Activity context) { 

    cursor = context.managedQuery(
      MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, projection, 
      selection, null, null); 

} 

public ArrayList<HashMap<String, String>> getPlayList() { 

    while (cursor.moveToNext()) { 
     HashMap<String, String> song = new HashMap<String, String>(); 
     song.put("ID", cursor.getString(0)); 
     song.put("songTitle", cursor.getString(1)); 
     song.put("songPath", cursor.getString(2)); 
     song.put("Artist", cursor.getString(3)); 
     song.put("Duration", cursor.getString(4)); 
     songsList.add(song); 
    } 
    // return songs list array 
    return songsList; 
} 

代碼來獲取音頻代碼使用音頻ID在ListAdapter getview方法

Uri sArtworkUri = Uri 
       .parse("content://media/external/audio/albumart"); 
     Uri uri = ContentUris.withAppendedId(sArtworkUri, 
       Long.parseLong(songsList.get(position).get("ID"))); 
     songimage.setImageURI(uri);
