我正在开发一个应用程序在Android。我不知道如何从应用程序发送电子邮件?
当前回答
我是这么做的。很好很简单。
String emailUrl = "mailto:email@example.com?subject=Subject Text&body=Body Text";
Intent request = new Intent(Intent.ACTION_VIEW);
request.setData(Uri.parse(emailUrl));
startActivity(request);

我很久以前就一直在用这个,看起来不错,没有非电子邮件应用程序显示。这是发送电子邮件意图的另一种方式:
Intent intent = new Intent(Intent.ACTION_SENDTO); // it's not ACTION_SEND
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject of email");
intent.putExtra(Intent.EXTRA_TEXT, "Body of email");
intent.setData(Uri.parse("mailto:default@example.com")); // or just "mailto:" for blank
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // this will make such that when user returns to your app, your app is displayed, instead of the email app.
startActivity(intent);
这将只显示您的电子邮件客户端(以及PayPal出于某些未知的原因)
public void composeEmail() {
Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setData(Uri.parse("mailto:"));
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"hi@example.com"});
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "Body");
try {
startActivity(Intent.createChooser(intent, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MainActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
}
使用. settype ("message/rfc822")或者选择器会显示所有(许多)支持发送意图的应用程序。
其他解决方案可以是
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
emailIntent.setType("plain/text");
emailIntent.setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"someone@gmail.com"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Yo");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Hi");
startActivity(emailIntent);
假设大多数android设备已经安装了GMail应用程序。
/**
* Will start the chosen Email app
*
* @param context current component context.
* @param emails Emails you would like to send to.
* @param subject The subject that will be used in the Email app.
* @param forceGmail True - if you want to open Gmail app, False otherwise. If the Gmail
* app is not installed on this device a chooser will be shown.
*/
public static void sendEmail(Context context, String[] emails, String subject, boolean forceGmail) {
Intent i = new Intent(Intent.ACTION_SENDTO);
i.setData(Uri.parse("mailto:"));
i.putExtra(Intent.EXTRA_EMAIL, emails);
i.putExtra(Intent.EXTRA_SUBJECT, subject);
if (forceGmail && isPackageInstalled(context, "com.google.android.gm")) {
i.setPackage("com.google.android.gm");
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
} else {
try {
context.startActivity(Intent.createChooser(i, "Send mail..."));
} catch (ActivityNotFoundException e) {
Toast.makeText(context, "No email app is installed on your device...", Toast.LENGTH_SHORT).show();
}
}
}
/**
* Check if the given app is installed on this devuice.
*
* @param context current component context.
* @param packageName The package name you would like to check.
* @return True if this package exist, otherwise False.
*/
public static boolean isPackageInstalled(@NonNull Context context, @NonNull String packageName) {
PackageManager pm = context.getPackageManager();
if (pm != null) {
try {
pm.getPackageInfo(packageName, 0);
return true;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}
return false;
}
