如何将Textview数据保存到Android中的文本文件和电子邮件中。 [英] How Do I Save Textview Data Into A Text File And Email In Android.

问题描述

大家好吧



我正在写一个关于完整的Android应用程序，除了我遇到的一个小问题。当用户在计算后得到他们的结果时，金额会显示在TextViews中，我需要帮助的问题是将这些值保存在文本文件中，而不是通过电子邮件发送给相应的人。这一切都应该通过单击按钮来完成。

Hi all

I am writing an android app which is about complete except for a small problem i have run into. When a user gets their results after a calculation, the amounts are displayed into TextViews, my problem which i need help in is getting those values saved in a text file and than emailed to the respective person. This should all be done with the click of a button.

推荐答案

您可以通过以下代码示例将textview数据保存到文本文件：

You can save your textview data to a text file by this code example:

File root = new File(YOUR_DIRECTORY_PATH);
  File gpxfile = new File(root, "yourFileName.txt");
  FileWriter writer = new FileWriter(gpxfile);
  writer.append(yourTextview.getText().toString());
  writer.flush();
  writer.close();

要将文件作为电子邮件附件发送，您可以尝试：

To send the file as email attachment you can try:

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(YOUR_FILE_PATH));
sendIntent.setType("text/plain");
startActivity(sendIntent);

您可以为这两项任务制作两种不同的方法，并在按钮点击事件中使用它们，就是这样。

You can make 2 separate methods for these 2 tasks and use them in your button click event, that's all.

这可以分两步完成。

首先你需要将内容保存在一个文件中

保存在文本文件中



一旦保存，您需要发送到一个电子邮件地址

Once you save, you need to sent to a email address
