File ruta_sd = Environment.getExternalStorageDirectory(); File f = new File(ruta_sd.getAbsolutePath(), "datos.txt");

      BufferedReader fin =new BufferedReader(
              new InputStreamReader(
                      new FileInputStream(f)));
      String texto = fin.readLine();
      fin.close();

      textohere.setText(texto);
