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?


当前回答

这对我来说非常有效:

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setData(Uri.parse("mailto:" + address));
    startActivity(Intent.createChooser(intent, "E-mail"));

下面的代码对我有用!!

import android.support.v4.app.ShareCompat;
    .
    .
    .
    .
final Intent intent = ShareCompat.IntentBuilder
                        .from(activity)
                        .setType("application/txt")
                        .setSubject(subject)
                        .setText("Hii")
                        .setChooserTitle("Select One")
                        .createChooserIntent()
                        .addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET)
                        .addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

activity.startActivity(intent);

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);
}

只发送到电子邮件客户端-与多个附件

有很多解决方案,但都是局部有效的。

Mailto可以正确地过滤电子邮件应用程序,但它不能不发送流/文件。

Message /rfc822打开了大量的应用程序和电子邮件客户端

所以,这个问题的解决方法是两者都用。

首先使用mailto意图解析意图活动 然后将数据设置为每个已解析的活动以发送所需的数据

private void share()
{
     Intent queryIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"));
     Intent dataIntent  = getDataIntent();

     Intent targetIntent = getSelectiveIntentChooser(context, queryIntent, dataIntent);
     startActivityForResult(targetIntent);
}

构建所需的数据意图,其中填充需要共享的数据

private Intent getDataIntent()
{
        Intent dataIntent = buildIntent(Intent.ACTION_SEND, null, "message/rfc822", null);

        // Set subject
        dataIntent.putExtra(Intent.EXTRA_SUBJECT, title);

        //Set receipient list.
        dataIntent.putExtra(Intent.EXTRA_EMAIL, toRecipients);
        dataIntent.putExtra(Intent.EXTRA_CC, ccRecipients);
        dataIntent.putExtra(Intent.EXTRA_BCC, bccRecipients);
        if (hasAttachments())
        {
            ArrayList<Uri> uris = getAttachmentUriList();

            if (uris.size() > 1)
            {
                intent.setAction(Intent.ACTION_SEND_MULTIPLE);
                dataIntent.putExtra(Intent.EXTRA_STREAM, uris);
            }
            else
            {
                dataIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris.get(0));
            }
        }

        return dataIntent;
}

protected ArrayList<Uri> getAttachmentUriList()
{
        ArrayList<Uri> uris = new ArrayList();
        for (AttachmentInfo eachAttachment : attachments)
        {
            uris.add(eachAttachment.uri);
        }

        return uris;
}

用于根据查询意图过滤所需意图的实用程序类

// Placed in IntentUtil.java
public static Intent getSelectiveIntentChooser(Context context, Intent queryIntent, Intent dataIntent)
{
        List<ResolveInfo> appList = context.getPackageManager().queryIntentActivities(queryIntent, PackageManager.MATCH_DEFAULT_ONLY);

        Intent finalIntent = null;

        if (!appList.isEmpty())
        {
            List<android.content.Intent> targetedIntents = new ArrayList<android.content.Intent>();

            for (ResolveInfo resolveInfo : appList)
            {
                String packageName = resolveInfo.activityInfo != null ? resolveInfo.activityInfo.packageName : null;

                Intent allowedIntent = new Intent(dataIntent);
                allowedIntent.setComponent(new ComponentName(packageName, resolveInfo.activityInfo.name));
                allowedIntent.setPackage(packageName);

                targetedIntents.add(allowedIntent);
            }

            if (!targetedIntents.isEmpty())
            {
                //Share Intent
                Intent startIntent = targetedIntents.remove(0);

                Intent chooserIntent = android.content.Intent.createChooser(startIntent, "");
                chooserIntent.putExtra(android.content.Intent.EXTRA_INITIAL_INTENTS, targetedIntents.toArray(new Parcelable[]{}));
                chooserIntent.addFlags(android.content.Intent.FLAG_GRANT_READ_URI_PERMISSION);

                finalIntent = chooserIntent;
            }

        }

        if (finalIntent == null) //As a fallback, we are using the sent data intent
        {
            finalIntent = dataIntent;
        }

        return finalIntent;
}

根据Android开发者官方文档,这是发送电子邮件意图的正确方式

添加以下代码行到你的应用程序:

Intent intent = new Intent(Intent.ACTION_SEND);//common intent 
intent.setData(Uri.parse("mailto:")); // only email apps should handle this

可选:添加主体和主题,就像这样

intent.putExtra(Intent.EXTRA_SUBJECT, "Your Subject Here");
intent.putExtra(Intent.EXTRA_TEXT, "E-mail body" );

你的问题里已经加了这句话

intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"hello@example.com"});

这将是收件人的地址,这意味着用户将向您(开发人员)发送电子邮件。

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();
