如何将电子邮件客户端直接启动到收件箱视图？

Question

如果不拨打特定的包裹,这是否可行？我已经找到了无数通过意图发送电子邮件的例子,但是我无法通过按下按钮来打开设备上的默认电子邮件客户端(如果用户有多个客户端,最好使用选择器对话框).

Answer 1

没有默认/简单的方法来做到这一点.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);
    }

Intent打开"设备上的默认电子邮件客户端"的"收件箱视图" 没有标准操作.
