Java 将声音另存为通知崩溃应用程序

因此，我正在制作一个音板应用程序，并尝试实现将声音保存为通知。然而，问题是，一旦用户确认保存为通知，应用程序就会崩溃

以下是我到目前为止的情况：

private OnItemLongClickListener longClickListener = new OnItemLongClickListener() {
    public boolean onItemLongClick(AdapterView<?> parent, View v,
            final int position, long id) {

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        CharSequence[] menu = new CharSequence[1];
        menu[0] = "Notification";
        // menu[1] = "Ringtone";

        builder.setTitle("Save As...").setItems(menu,
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        // The 'which' argument contains the index position
                        // of the selected item
                        switch (which) {
                        case 0:
                            if (saveAsNotification(getSounds()
                                    .get(position))) {
                                Toast.makeText(getActivity(),
                                        "Saved as Notification",
                                        Toast.LENGTH_SHORT).show();
                            } else {
                                Toast.makeText(getActivity(),
                                        "Failed to Save Notification",
                                        Toast.LENGTH_SHORT).show();
                            }
                            break;
                        default:
                            break;
                        }
                    }
                });
        builder.create().show();
        return true;
    }
};

public boolean saveAsNotification(Sound sound) {
    byte[] buffer = null;
    InputStream fIn = getActivity().getBaseContext().getResources()
            .openRawResource(sound.getSoundResourceId());
    int size = 0;

    try {
        size = fIn.available();
        buffer = new byte[size];
        fIn.read(buffer);
        fIn.close();
    } catch (IOException e) {
        e.printStackTrace();
        return false;
    }

    String path = Environment.getExternalStorageDirectory().getPath()
            + "/media/audio/notifications/";
    String filename = sound.getDescription() + ".ogg";

    boolean exists = (new File(path)).exists();
    if (!exists) {
        new File(path).mkdirs();
    }

    FileOutputStream save;
    try {
        save = new FileOutputStream(path + filename);
        save.write(buffer);
        save.flush();
        save.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return false;
    } catch (IOException e) {
        e.printStackTrace();
        return false;
    }

    getActivity().sendBroadcast(
            new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri
                    .parse("file://" + path + filename)));

    File k = new File(path, filename);

    ContentValues values = new ContentValues();
    values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
    values.put(MediaStore.MediaColumns.TITLE, sound.getDescription());
    values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/ogg");
    values.put(MediaStore.Audio.Media.ARTIST, "soundboarder");
    values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
    values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
    values.put(MediaStore.Audio.Media.IS_ALARM, true);
    values.put(MediaStore.Audio.Media.IS_MUSIC, false);

    // Insert it into the database
    getActivity().getContentResolver()
            .insert(MediaStore.Audio.Media.getContentUriForPath(k
                    .getAbsolutePath()), values);

    return true;
}

对话框弹出“很好”，但只要我单击“另存为通知”，应用程序就会崩溃。

我认为这部分代码导致了错误 InputStream fIn=getActivity.getBaseContext.getResources.openRawResourcesound.getSoundResourceId

错误消息说您正在尝试打开ID为-1的资源，请确保getSoundResourceId返回正确的ID号。

我认为在您尝试创建InputStream时会出现问题，因为没有具有该ID的资源。@Titus您能详细说明一下吗？我是一个完全的初学者，当谈到这个东西，所以你能解释一下如何修复它或为什么它不工作？
