java - Android App/播放Raw或Assets文件夹中的音频/视频文件，而不是/SD Card/

Question

请任何人帮助我让此Android应用从Raw或Assets文件夹播放音频/视频文件，而不是从/ SDCard /播放。

我应该在下面的这段代码中进行哪些更改？

这是Tutorial代码。

问候。

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"));
    }
}
}

Answer 1

您可以尝试从 Assets 文件夹中加载文件。考虑 Assets 文件夹中有铃声文件夹，然后在您的 Activity 中使用

AssetManager assetManager = this.getResources().getAssets();
String[] files = null;
try {
files = assetManager.list("ringtone"); //ringtone is folder name
} catch (Exception e) {
Log.e(LOG_TAG, "ERROR: " + e.toString());
}

这样您就可以从Assets文件夹中获取文件，然后获取文件名并将文件名传递到您的列表中
