获取音乐播放器Android的专辑封面
作者:互联网
我想知道如何在音乐播放器中返回albumart图像的代码(Function).你能解释一下我应该通过什么参数吗?我可以将文件路径传递给函数.
imported required libraries
public class SongsManager {
// SDCard Path
final String MEDIA_PATH = new String("/sdcard/");
private ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
// Constructor
public SongsManager(){
}
public ArrayList<HashMap<String, String>> getPlayList(){
File home = new File(MEDIA_PATH);
if (home.listFiles(new FileExtensionFilter()).length > 0) {
for (File file : home.listFiles(new FileExtensionFilter())) {
HashMap<String, String> song = new HashMap<String, String>();
song.put("songTitle", file.getName().substring(0, (file.getName().length() - 4)));
song.put("songPath", file.getPath());
// Adding each song to SongList
songsList.add(song);
}
}
// return songs list array
return songsList;
}
class FileExtensionFilter implements FilenameFilter {
public boolean accept(File dir, String name) {
return (name.endsWith(".mp3") || name.endsWith(".MP3"));
}
}
}
解决方法:
MediaMetadataRetriever mmr = new MediaMetadataRetriever();
mmr.setDataSource(file.getPath());
byte [] data = mmr.getEmbeddedPicture();
Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
imageView.setImageBitmap(bitmap);
试试上面的代码
