Android Studio mailto Intent不显示主题和邮件正文

我正在尝试从我的Android应用发送电子邮件。单击按钮，gmail应打开并显示一个新电子邮件，其中包含我先前定义的收件人，主题和电子邮件正文。到目前为止，我已经尝试发送Intent.ACTION_VIEW和Intent.ACTION_SENDTO。两者都只与收件人一起显示我的草稿。主题和信息都被压抑了。奇怪的是，在使用仿真器时，它工作得很好。还试图锁定android错误日志。好像我没有许可。真的是权限问题，还是其他问题？我真的很感激任何帮助

这是我的代码：

  • 通过ACTION_VIEW发送电子邮件

    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(“mailto:” + to));

    intent.putExtra(intent.EXTRA_SUBJECT, subject);

    intent.putExtra(intent.EXTRA_TEXT, message);

    mainActivity.startActivity(intent);

  • 通过ACTION_SENDTO发送电子邮件

    Intent email = new Intent(Intent.ACTION_SENDTO);

    email.setType(“message/rfc822”);

    email.putExtra(Intent.EXTRA_EMAIL, new String[]{to});

    email.putExtra(Intent.EXTRA_SUBJECT, subject);

    email.putExtra(Intent.EXTRA_TEXT, message);

    mainActivity.startActivity(Intent.createChooser(email, “Choose an Email client :”));

回答：

试试这个代码，它对我有用。

Intent intent = new Intent(Intent.ACTION_SENDTO);
            intent.setData(Uri.parse("mailto:")); // only email apps should handle this
            intent.putExtra(Intent.EXTRA_EMAIL, new String[]{email});
            intent.putExtra(Intent.EXTRA_SUBJECT, "Subject here");
            intent.putExtra(Intent.EXTRA_TEXT,"Body Here");
            if (intent.resolveActivity(getPackageManager()) != null) {
                startActivity(intent);
            }

还要在android清单中添加意图过滤器。

<activity ...>
<intent-filter>
    <action android:name="android.intent.action.SENDTO" />
    <data android:scheme="mailto" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>
