问将参数传递给Asynctask

  private class Setup extends AsyncTask<Void, Integer, Void> {

    @Override
    protected Void doInBackground(Void... params) {
        try {
            if (!(getIntent().getExtras().isEmpty())) {
                Bundle gotid = getIntent().getExtras();
                identifier = gotid.getString("key");
            }
        } catch (Exception e) {
            e.getStackTrace();
        } finally {

            if (identifier.matches("abc")) {
                publishProgress(0);
                db.insert_fri();
            } else if ((identifier.matches("xyz"))) {
                publishProgress(1);
                db.insert_met();
            }
        }
        return null;
    }

    @Override
    protected void onProgressUpdate(Integer... i) {
        // start the song here
        if (i[0] == 0) {
            song.setLooping(true);
            song.start();
        }
    }

    @Override
    protected void onPostExecute(Void res) {

    }

    @Override
    protected void onPreExecute() {
        // do something before execution
    }
}
