【中文标题】将捆绑包/意图传递给另一个活动？【英文标题】：Passing bundles/intent to another activity? 【发布时间】：2021-07-16 21:39:22 【问题描述】：我是编码新手。我正在尝试将电影数组和日期传递给下一个 Main_Activity3，以便它可以打印在页面上。但我不知道如何将所需的数据放入意图中。对于电影，我只需要将所选电影传递到其他页面。
Main_Activity2

【问题讨论】：
删除了android-studio 标签，因为该标签用于处理与 Android Studio 产品相关的问题/问题。您的问题是一个通用的 Android 问题，与 Android Studio 无关。
【参考方案1】：
要发送选定的电影和日期，您可以执行以下操作： （假设您不需要发送整个电影列表，只需发送选定的电影）
// set selectedDate = date in milliseconds as "long" variable
intent.putExtra("movie", selectedMovie);
intent.putExtra("date", selectedDate);
在接收Activity 时，像这样从Intent 中取出数据：
movies = intent.getParcelableExtra("movie");
dateInMillis = intent.getLongExtra("date");
如果您的日期为mYear, mMmonth, mDay，您也可以单独添加这些日期，如下所示：
intent.putExtra("year", mYear);
intent.putExtra("month", mMonth);
intent.putExtra("day", mDay);
并像这样在接收Activity 中提取它们：
mYear = intent.getIntExtra("year", -1);
mMonth = intent.getIntExtra("month", -1);
mDay = intent.getIntExtra("day", -1);
注意：-1 参数是默认值，以防 Intent 中不存在附加值，它们应该存在。
