java - 从 Android 应用程序启动包含消息和收件人的 Telegram 应用程序

Question

我需要从我自己的 Android 应用程序中打开 Telegram，预先填充消息和收件人(并且不必在 Chrome 或 Telegram 之间进行选择)，我用这段代码实现了第一个:

        final String appName = "org.telegram.messenger";
        Intent tIntent = new Intent(Intent.ACTION_SEND);
        tIntent.setType("text/plain");
        tIntent.setPackage(appName);
        tIntent.putExtra(Intent.EXTRA_TEXT, msg);
        mUIActivity.startActivity(tIntent);

第二个代码如下:

        Intent tIntent = new Intent(Intent.ACTION_VIEW);
        tIntent.setData(Uri.parse("http://telegram.me/USERID"));
        startActivity(tIntent);

(为了简单起见，我删除了所有检查，例如 isTelegramInstalled)

我尝试混合使用这两种方法添加一些额外的 Intent ，例如 msg，我们得到的代码将一键打开 Telegram，其中包含预先填充的消息和收件人:

        Intent telegramIntent = new Intent(Intent.ACTION_SEND);
        tIntent.setDataAndType(Uri.parse("http://telegram.me/username"), "text/plain");
        final String appName = "org.telegram.messenger";
        tIntent.setPackage(appName);
        tIntent.putExtra(Intent.EXTRA_TEXT, "hello");
        startActivity(tIntent);

...aa但它不起作用!

android.content.ActivityNotFoundException:找不到处理 Intent 的 Activity { act=android.intent.action.SEND dat=http://telegram.me/... flg=0x1 pkg=org.telegram. Messenger Clip={null T:hello} (有额外内容) }


知道如何实现这一目标吗？

请尝试以下功能来打开 Telegram

public static void openTelegram(Activity activity, String userName) {
    Intent general = new Intent(Intent.ACTION_VIEW, Uri.parse("https://t.com/" + userName));
    HashSet<String> generalResolvers = new HashSet<>();
    List<ResolveInfo> generalResolveInfo = activity.getPackageManager().queryIntentActivities(general, 0);
    for (ResolveInfo info : generalResolveInfo) {
        if (info.activityInfo.packageName != null) {
            generalResolvers.add(info.activityInfo.packageName);
        }
    }

    Intent telegram = new Intent(Intent.ACTION_VIEW, Uri.parse("https://t.me/" + userName));
    int goodResolver = 0;
    // gets the list of intents that can be loaded.
    List<ResolveInfo> resInfo = activity.getPackageManager().queryIntentActivities(telegram, 0);
    if (!resInfo.isEmpty()) {
        for (ResolveInfo info : resInfo) {
            if (info.activityInfo.packageName != null && !generalResolvers.contains(info.activityInfo.packageName)) {
                goodResolver++;
                telegram.setPackage(info.activityInfo.packageName);
            }
        }
    }
    //TODO: if there are several good resolvers create custom chooser
    if (goodResolver != 1) {
        telegram.setPackage(null);
    }
    if (telegram.resolveActivity(activity.getPackageManager()) != null) {
        activity.startActivity(telegram);
    }
} 

希望对您有帮助!

谢谢。
