我正在尝试将按钮链接到邮件应用。不发送邮件,只是打开收件箱。
我应该使用Intent intent = new Intent(...)
吗?
如果是这样,( )

如果目标是打开默认电子邮件应用以查看收件箱,那么关键是添加意图类别并使用ACTION_MAIN意图,如下所示:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_APP_EMAIL);
getActivity().startActivity(intent);

是的,可以打开Android默认电子邮件收件箱
使用此代码:
Intent intent = getPackageManager().getLaunchIntentForPackage("com.android.email");
startActivity(intent);
此代码有效,您必须先配置Android设备默认邮件。如果您已经配置了邮件,它可以正常工作。否则,强制关闭NullPointerException
。

这段代码对我有用。它打开一个选择器,所有电子邮件应用程序都注册到设备并直接进入收件箱:
Intent emailIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("mailto:"));
PackageManager pm = getPackageManager();
List<ResolveInfo> resInfo = pm.queryIntentActivities(emailIntent, 0);
if (resInfo.size() > 0) {
ResolveInfo ri = resInfo.get(0);
// First create an intent with only the package name of the first registered email app
// and build a picked based on it
Intent intentChooser = pm.getLaunchIntentForPackage(ri.activityInfo.packageName);
Intent openInChooser =
Intent.createChooser(intentChooser,
getString(R.string.user_reg_email_client_chooser_title));
// Then create a list of LabeledIntent for the rest of the registered email apps
List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();
for (int i = 1; i < resInfo.size(); i++) {
// Extract the label and repackage it in a LabeledIntent
ri = resInfo.get(i);
String packageName = ri.activityInfo.packageName;
Intent intent = pm.getLaunchIntentForPackage(packageName);
intentList.add(new LabeledIntent(intent, packageName, ri.loadLabel(pm), ri.icon));
}
LabeledIntent[] extraIntents = intentList.toArray(new LabeledIntent[intentList.size()]);
// Add the rest of the email apps to the picker selection
openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
startActivity(openInChooser);
}

您可以使用以下方法打开Android默认电子邮件客户端:
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.setClassName("com.android.email", "com.android.email.activity.Welcome");
emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

没有附件时,您可以简单地使用以下代码:
Intent i = new Intent(Intent.ACTION_SENDTO);
i.setData(Uri.parse("mailto:support@mailname.com"));
i.putExtra(Intent.EXTRA_SUBJECT, "Feedback/Support");
startActivity(Intent.createChooser(emailIntent, "Send feedback"));

对于 kotlin:
fun composeEmail(addresses: Array<String>, subject: String) {
val intent = Intent(Intent.ACTION_SENDTO).apply {
data = Uri.parse("mailto:") // only email apps should handle this
putExtra(Intent.EXTRA_EMAIL, addresses)
putExtra(Intent.EXTRA_SUBJECT, subject)
}
if (intent.resolveActivity(packageManager) != null) {
startActivity(intent)
}
}

有点晚了,这是正确的工作代码。
Intent intent = Intent.makeMainSelectorActivity(
Intent.ACTION_MAIN,
Intent.CATEGORY_APP_EMAIL
);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(Intent.createChooser(intent, "Email"));
