活动中的活动

Question

我正试着在我的主要活动中开始一项活动。我正在尝试通过电子邮件发送数据。但是当我运行代码时，我的程序崩溃了。下面是我开始新活动的代码

Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("plain/html");
    intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"aaa@gmail.com","ssss@yahoo.com"});
    intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
    intent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml("my html text goes here"));
    startActivity(intent);

Answer 1

尝试使用Intent.createChooser方法查找应该发送邮件的应用程序，如下所示：

    Intent emailIntent = new Intent(Intent.ACTION_SEND);
    emailIntent.setType(EMAIL_CONTENT_TYPE);

    emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {"aaa@gmail.com","ssss@yahoo.com"});
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "subject");
    emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml("my html text goes here"));

    Intent chooser = Intent.createChooser(emailIntent, "Choose the application to send the email");
    startActivity(chooser);
