Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_EMAIL, "emailaddress@emailaddress.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "I'm email body.");
startActivity(Intent.createChooser(intent, "Send Email"));
上面的代码打开一个对话框，显示以下应用程序:-蓝牙，谷歌文档，雅虎邮件，Gmail, Orkut, Skype等。
实际上，我想过滤这些列表选项。我只想显示电子邮件相关的应用程序，如Gmail和雅虎邮件。怎么做呢?
我曾在Android Market应用中看到过这样的例子。
打开Android Market应用程序
打开任何开发者指定了他/她的电子邮件地址的应用程序。(如果你找不到这样的应用程序，请打开我的应用程序:- market://details?id=com.becomputer06.vehicle.diary.free，或通过“车辆日记”搜索)
向下滚动到“开发者”
点击“发送电子邮件”
对话框只显示电子邮件应用程序，如Gmail，雅虎邮件等。它不显示蓝牙，Orkut等。什么样的代码产生这样的对话?
主要有三种方法:
String email = /* Your email address here */
String subject = /* Your subject here */
String body = /* Your body here */
String chooserTitle = /* Your chooser title here */
1. 自定义Uri:
Uri uri = Uri.parse("mailto:" + email)
.buildUpon()
.appendQueryParameter("subject", subject)
.appendQueryParameter("body", body)
.build();
Intent emailIntent = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(Intent.createChooser(emailIntent, chooserTitle));
2. 使用Intent附加:
Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" + email));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, body);
//emailIntent.putExtra(Intent.EXTRA_HTML_TEXT, body); //If you are using HTML in your body text
startActivity(Intent.createChooser(emailIntent, "Chooser Title"));
3.支持库ShareCompat:
Activity activity = /* Your activity here */
ShareCompat.IntentBuilder.from(activity)
.setType("message/rfc822")
.addEmailTo(email)
.setSubject(subject)
.setText(body)
//.setHtmlText(body) //If you are using HTML in your body text
.setChooserTitle(chooserTitle)
.startChooser();
编辑:不再工作与Gmail的新版本
这是我当时发现的唯一方法，让它与任何角色一起工作。
doreamon的答案是正确的，因为它适用于Gmail新版本的所有角色。
旧的回答:
这是我的。它似乎适用于所有Android版本，支持主题和消息体，并支持完整的utf-8字符:
public static void email(Context context, String to, String subject, String body) {
StringBuilder builder = new StringBuilder("mailto:" + Uri.encode(to));
if (subject != null) {
builder.append("?subject=" + Uri.encode(Uri.encode(subject)));
if (body != null) {
builder.append("&body=" + Uri.encode(Uri.encode(body)));
}
}
String uri = builder.toString();
Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse(uri));
context.startActivity(intent);
}
适用于所有android版本:
String[] to = {"email@server.com"};
Uri uri = Uri.parse("mailto:email@server.com")
.buildUpon()
.appendQueryParameter("subject", "subject")
.appendQueryParameter("body", "body")
.build();
Intent emailIntent = new Intent(ACTION_SENDTO, uri);
emailIntent.putExtra(EXTRA_EMAIL, TO);
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
更新到Android 10，现在使用Kotlin…
fun Context.sendEmail(
address: String?,
subject: String?,
body: String?,
) {
val recipients = arrayOf(address)
val uri = address.toUri()
.buildUpon()
.appendQueryParameter("subject", subject)
.appendQueryParameter("body", body)
.build()
val emailIntent = Intent(ACTION_SENDTO, uri).apply {
setData("mailto:$address".toUri());
putExtra(EXTRA_SUBJECT, subject);
putExtra(EXTRA_TEXT, body);
putExtra(EXTRA_EMAIL, recipients)
}
val pickerTitle = getString(R.string.some_title)
ContextCompat.startActivity(this, Intent.createChooser(emailIntent, pickerTitle, null)
}
.．.在更新到API 30之后，代码没有填充电子邮件客户端的主题和主体(例如Gmail)。但我在这里找到了答案:
fun Context.sendEmail(
address: String?,
subject: String?,
body: String?,
) {
val selectorIntent = Intent(ACTION_SENDTO)
.setData("mailto:$address".toUri())
val emailIntent = Intent(ACTION_SEND).apply {
putExtra(EXTRA_EMAIL, arrayOf(address))
putExtra(EXTRA_SUBJECT, subject)
putExtra(EXTRA_TEXT, body)
selector = selectorIntent
}
startActivity(Intent.createChooser(emailIntent, getString(R.string.send_email)))
}
