我看过这个媒体播放器tutorial,我想知道是否有人帮助我直接从Raw
文件夹而不是/SdCard/
设置音频文件?
import java.io.File;
import java.io.FilenameFilter;
import java.util.ArrayList;
import java.util.HashMap;
public class SongsManager {
// SDCard Path
@SuppressLint("SdCardPath")
final String MEDIA_PATH = new String("/sdcard/");
private ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
// Constructor
public SongsManager() {
}
/**
* Function to read all mp3 files from sdcard and store the details in
* ArrayList
* */
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 to filter files which are having .mp3 extension
* */
class FileExtensionFilter implements FilenameFilter {
public boolean accept(File dir, String name) {
return (name.endsWith(".mp3") || name.endsWith(".MP3"));
}
}
}
答案 0 :(得分:3)
以下是您要找的内容
原始文件夹访问
Uri uri=Uri.parse("android.resource://" + this.getPackageName() + "/" + R.raw.test);
SD卡访问
final Uri uri=Uri.parse(Environment.getExternalStorageDirectory()+"/Video/tmn.wmv");
您的视频位于SDCARD的视频文件夹中
将媒体播放器源设置为原始文件夹
MediaPlayer mediaPlayer = new MediaPlayer();
Uri uri=Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.test);
mediaPlayer.setDataSource(this,uri);
