我试图从存储在数组列表中的firestore数据库中获取多个价格的值，并将它们相加以获得总价。问题是它们的大小不一样，我得到的是Java。lang.IndexOutOfBoundsException：索引：1，尺寸：1

while (name1.count() > i) {
  try {
    priceBreakdown += "option " + (i + 1).toString() + ":\n" + name1[i] + price1[contador] + "$\n"
    totalPrice += "price " + (i + 1).toString() + "=>\n" + (hotels[i] * days).toString() + "$\n"
    while (name2.count() > j) {
      priceBreakdown += "option " + (i + 1).toString() + "=>\n" + name2[j] + price2[j] + "&\n"
      totalPrice += "price " + (i + 1).toString() + "=>\n" + (Restaurants[j] * days).toString() + " Euros\n"
      j++
    }
    i++
  } catch (e: Exception) {
    Log.i(TAG, e.toString())
  }
}

我尝试了很多方法，但都没有成功。就像这样：

if (name1.count() > name2.count()) {
  while (name1.count() > i) {
    try {
      priceBreakdown += "option " + (i + 1).toString() + ":\n" + name1[i] + price1[contador] + "$\n"
      totalPrice += "price " + (i + 1).toString() + "=>\n" + (hotels[i] * days).toString() + "$\n"
      while (name2.count() > j) {
        priceBreakdown += "option " + (i + 1).toString() + "=>\n" + name2[j] + price2[j] + "&\n"
        totalPrice += "price " + (i + 1).toString() + "=>\n" + (Restaurants[j] * days).toString() + " Euros\n"
        j++
      }
      i++
    } catch (e: Exception) {
      Log.i(TAG, e.toString())
    }
  }
} else if (name2.count() > name1.count()) {
  while (name2.count() > i) {
    try {
      priceBreakdown += "option " + (i + 1).toString() + ":\n" + name1[i] + price1[contador] + "$\n"
      totalPrice += "price " + (i + 1).toString() + "=>\n" + (hotels[i] * days).toString() + "$\n"
      while (name2.count() > j) {
        priceBreakdown += "option " + (i + 1).toString() + "=>\n" + name2[j] + price2[j] + "&\n"
        totalPrice += "price " + (i + 1).toString() + "=>\n" + (Restaurants[j] * days).toString() + " Euros\n"
        j++
      }
      i++
    } catch (e: Exception) {
      Log.i(TAG, e.toString())
    }
  }
}

但它给了我同样的错误。
