for(int i=0;i对于(int i=0;i,这是因为您想要显示的内容必须是额外文本的一部分:

sendIntent.putExtra(Intent.EXTRA_文本,“要在此处打印的所有内容”);


因此,您必须使用数据构建一个字符串,然后使用完整的字符串创建额外的字符串。

公共静态最终字符串额外文本

与意图关联的常量字符序列,用于 操作\u SEND以提供要发送的文字数据。请注意,这可能会 是已设置样式的CharSequence,因此必须使用Bundle.getCharSequence()来 找回它

因此,在调用电子邮件应用程序之前,您应该首先将双数组转换为
字符串

步骤1:编写一个将双数组转换为字符串的方法

private String convertDoubleArrayToString(double[] array) {
    StringBuilder sb = new StringBuilder();
    for (double number: array) {
        sb.append(number).append(" ");
    }
    return sb.toString();
}
步骤2:将代码更改为

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Respiration Rate: " + convertDoubleArrayToString(plot_array));
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
