Android Studio mailto Intent不显示主题和邮件正文 [英] Android Studio mailto Intent doesn't show subject and mail body

问题描述

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.主题和消息都被压抑了.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? 我真的很感谢任何帮助 欢呼

I'm trying to send an e-mail from my Android App. With the click on a button, gmail should open and show a new email with my previously defined recipient, subject and email body. So far I've tried sending the Intent.ACTION_VIEW as well as Intent.ACTION_SENDTO. Both show my draft with the recipient only. Both subject and message are being opressed. Weird thing is when using the emulator, it works just fine. Also was trying to lock at the android errorlog. Seems like i don't have permission. Is it really a permission problem or could it be something else? I'd really appreciate any help cheers

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 :"));

• logcat的错误消息

推荐答案

尝试一下此代码，它对我有用.

try out this code, it worked for me.

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.

also add intent filter in android manifest.

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