我正在开发一款安卓应用程序。我不知道如何从应用程序中发送电子邮件?
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();
}
}
intent.type =“message/rfc822”; intent.type =“text/html”;
,因为它会导致异常。 - CoolMindString 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);
Intent i = new Intent(Intent.ACTION_SENDTO);
i.setType("message/rfc822");
i.setData(Uri.parse("mailto:"));
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"test@gmail.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT , "body of email");
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
这是在Android上发送电子邮件最简洁的方法。
val intent = Intent(Intent.ACTION_SENDTO).apply {
data = Uri.parse("mailto:")
putExtra(Intent.EXTRA_EMAIL, arrayOf("email@example.com"))
putExtra(Intent.EXTRA_SUBJECT, "Subject")
putExtra(Intent.EXTRA_TEXT, "Email body")
}
if (intent.resolveActivity(packageManager) != null) {
startActivity(intent)
}
<queries>
<intent>
<action android:name="android.intent.action.SENDTO" />
<data android:scheme="mailto" />
</intent>
</queries>
Html.fromHtml(
StringBuilder().append("<b>Hello world</b>").toString()
)
此函数首先直接使用 Gmail 发送电子邮件,如果找不到 Gmail,则会提示选择器。我在许多商业应用程序中使用了此功能,它运行良好。希望能对您有所帮助:
public static void sentEmail(Context mContext, String[] addresses, String subject, String body) {
try {
Intent sendIntentGmail = new Intent(Intent.ACTION_VIEW);
sendIntentGmail.setType("plain/text");
sendIntentGmail.setData(Uri.parse(TextUtils.join(",", addresses)));
sendIntentGmail.setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail");
sendIntentGmail.putExtra(Intent.EXTRA_EMAIL, addresses);
if (subject != null) sendIntentGmail.putExtra(Intent.EXTRA_SUBJECT, subject);
if (body != null) sendIntentGmail.putExtra(Intent.EXTRA_TEXT, body);
mContext.startActivity(sendIntentGmail);
} catch (Exception e) {
//When Gmail App is not installed or disable
Intent sendIntentIfGmailFail = new Intent(Intent.ACTION_SEND);
sendIntentIfGmailFail.setType("*/*");
sendIntentIfGmailFail.putExtra(Intent.EXTRA_EMAIL, addresses);
if (subject != null) sendIntentIfGmailFail.putExtra(Intent.EXTRA_SUBJECT, subject);
if (body != null) sendIntentIfGmailFail.putExtra(Intent.EXTRA_TEXT, body);
if (sendIntentIfGmailFail.resolveActivity(mContext.getPackageManager()) != null) {
mContext.startActivity(sendIntentIfGmailFail);
}
}
}
使用此功能发送电子邮件...
boolean success = EmailIntentBuilder.from(activity)
.to("support@example.org")
.cc("developer@example.org")
.subject("Error report")
.body(buildErrorReport())
.start();
使用 build.gradle:
compile 'de.cketti.mailto:email-intent-builder:1.0.0'
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);
假设大多数安卓设备已经预装了Gmail应用。
尝试这个简单的方法
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
buttonSend = (Button) findViewById(R.id.buttonSend);
textTo = (EditText) findViewById(R.id.editTextTo);
textSubject = (EditText) findViewById(R.id.editTextSubject);
textMessage = (EditText) findViewById(R.id.editTextMessage);
buttonSend.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String to = textTo.getText().toString();
String subject = textSubject.getText().toString();
String message = textMessage.getText().toString();
Intent email = new Intent(Intent.ACTION_SEND);
email.putExtra(Intent.EXTRA_EMAIL, new String[] { to });
// email.putExtra(Intent.EXTRA_CC, new String[]{ to});
// email.putExtra(Intent.EXTRA_BCC, new String[]{to});
email.putExtra(Intent.EXTRA_SUBJECT, subject);
email.putExtra(Intent.EXTRA_TEXT, message);
// need this to prompts email client only
email.setType("message/rfc822");
startActivity(Intent.createChooser(email, "Choose an Email client :"));
}
});
}
Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
"mailto","ebgsoldier@gmail.com", null));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Forgot Password");
emailIntent.putExtra(Intent.EXTRA_TEXT, "this is a text ");
startActivity(Intent.createChooser(emailIntent, "Send email..."));
public void openGmail(Activity activity) {
Intent emailIntent = new Intent(Intent.ACTION_VIEW);
emailIntent.setType("text/plain");
emailIntent.setType("message/rfc822");
emailIntent.setData(Uri.parse("mailto:"+activity.getString(R.string.mail_to)));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, activity.getString(R.string.app_name) + " - info ");
final PackageManager pm = activity.getPackageManager();
final List<ResolveInfo> matches = pm.queryIntentActivities(emailIntent, 0);
ResolveInfo best = null;
for (final ResolveInfo info : matches)
if (info.activityInfo.packageName.endsWith(".gm") || info.activityInfo.name.toLowerCase().contains("gmail"))
best = info;
if (best != null)
emailIntent.setClassName(best.activityInfo.packageName, best.activityInfo.name);
activity.startActivity(emailIntent);
}
