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 应用程序发送电子邮件.单击一个按钮，gmail 应该会打开并显示一封包含我之前定义的收件人、主题和电子邮件正文的新电子邮件.到目前为止，我已经尝试发送 Intent.ACTION_VIEW 和 Intent.ACTION_SENDTO.两者都只向收件人显示我的草稿.主题和信息都受到压制.奇怪的是当使用模拟器时，它工作得很好.还试图锁定 android 错误日志.好像没有权限这真的是权限问题还是其他原因?我真的很感激任何帮助干杯

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 :"));

• 来自 logcat 的错误消息

推荐答案

试试这个代码，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);
}

还在 android manifest 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>
