根据已安装的 Android 包名称自定义意图选择器过滤

Question

我想利用内置的意图选择器来显示自定义过滤的应用程序列表，供用户选择和启动。

我知道如何获取已安装软件包的列表：

final Intent myIntent = new Intent(android.content.Intent.ACTION_MAIN);  
List<ResolveInfo> resInfoList = getPackageManager().queryIntentActivities(myIntent, 0);

此时，我想根据包名称中包含的特定字符串（或字符串变体）来过滤列表，我也可以弄清楚如何执行此操作。

但这就是我陷入困境的地方。据我所知，

Intent.createChooser()

只接受单个目标Intent作为参数。我希望有一个重载，可以根据包和类名或其他内容获取意图列表。但我没有看到这样的事情。我是不是在某个地方错过了？

所以问题是，这是否可以使用内置选择器来完成，或者我是否必须使用 AlertDialog Builder 构建自己的选择器？我希望能避免后来的情况。

提前致谢。

Answer 1

这是我想出的一个解决方案。我使用它为选择器中的每个选择提供不同的意图数据，但您也可以轻松地从列表中删除意图。

List<Intent> targetedShareIntents = new ArrayList<Intent>();
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(shareIntent, 0);
if (!resInfo.isEmpty()) {
    for (ResolveInfo resolveInfo : resInfo) {
        String packageName = resolveInfo.activityInfo.packageName;
        Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
        targetedShareIntent.setType("text/plain");
        targetedShareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "subject to be shared");
        if (TextUtils.equals(packageName, "com.facebook.katana")) {
            targetedShareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "http://link-to-be-shared.com");
        } else {
            targetedShareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "text message to shared");
        }
        targetedShareIntent.setPackage(packageName);
        targetedShareIntents.add(targetedShareIntent);
    }
    Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[targetedShareIntents.size()]));
    startActivity(chooserIntent);
}

编辑

使用此方法时，我得到了一些应用程序的名称作为Android系统。如果有人遇到此错误，请在

targetedShareIntents.add(targetedShareIntent);

之前添加以下行

 targetedShareIntent.setClassName(
                        resolveInfo.activityInfo.packageName,
                        resolveInfo.activityInfo.name);

Answer 2

选择器唯一的一个附加参数是

Intent.EXTRA_INITIAL_INTENTS

。它的描述是：

Parcelable[]
意图或
LabeledIntent
对象设置为
putExtra(String, Parcelable[])
附加活动，以在使用
ACTION_CHOOSER
向用户显示时将其放置在选项列表的前面。

我没有在 Android 源代码中找到任何方法从列表中排除其他活动，因此似乎无法使用选择器执行您想要执行的操作。

编辑：这真的很容易找到。只需检查 ChooserActivity 和 ResolverActivity 源代码。这些班级规模相当小。

我做了一个小修改，列出了您想要按名称共享的应用程序列表。这几乎是您已经发布的内容，但添加了要按名称共享的应用程序

String[] nameOfAppsToShareWith = new String[] { "facebook", "twitter", "gmail" };
String[] blacklist = new String[]{"com.any.package", "net.other.package"};
// your share intent
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "some text");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "a subject");
// ... anything else you want to add invoke custom chooser
startActivity(generateCustomChooserIntent(intent, blacklist));

private Intent generateCustomChooserIntent(Intent prototype,
            String[] forbiddenChoices)
    {
        List<Intent> targetedShareIntents = new ArrayList<Intent>();
        List<HashMap<String, String>> intentMetaInfo = new ArrayList<HashMap<String, String>>();
        Intent chooserIntent;

        Intent dummy = new Intent(prototype.getAction());
        dummy.setType(prototype.getType());
        List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(dummy,0);

        if (!resInfo.isEmpty())
        {
            for (ResolveInfo resolveInfo : resInfo)
            {
                if (resolveInfo.activityInfo == null
                        || Arrays.asList(forbiddenChoices).contains(
                                resolveInfo.activityInfo.packageName))
                    continue;
                //Get all the posible sharers
                HashMap<String, String> info = new HashMap<String, String>();
                info.put("packageName", resolveInfo.activityInfo.packageName);
                info.put("className", resolveInfo.activityInfo.name);
                String appName = String.valueOf(resolveInfo.activityInfo
                        .loadLabel(getPackageManager()));
                info.put("simpleName", appName);
                //Add only what we want
                if (Arrays.asList(nameOfAppsToShareWith).contains(
                        appName.toLowerCase()))
                {
                    intentMetaInfo.add(info);
                }
            }

            if (!intentMetaInfo.isEmpty())
            {
                // sorting for nice readability
                Collections.sort(intentMetaInfo,
                        new Comparator<HashMap<String, String>>()
                        {
                            @Override public int compare(
                                    HashMap<String, String> map,
                                    HashMap<String, String> map2)
                            {
                                return map.get("simpleName").compareTo(
                                        map2.get("simpleName"));
                            }
                        });

                // create the custom intent list
                for (HashMap<String, String> metaInfo : intentMetaInfo)
                {
                    Intent targetedShareIntent = (Intent) prototype.clone();
                    targetedShareIntent.setPackage(metaInfo.get("packageName"));
                    targetedShareIntent.setClassName(
                            metaInfo.get("packageName"),
                            metaInfo.get("className"));
                    targetedShareIntents.add(targetedShareIntent);
                }
                String shareVia = getString(R.string.offer_share_via);
                String shareTitle = shareVia.substring(0, 1).toUpperCase()
                        + shareVia.substring(1);
                chooserIntent = Intent.createChooser(targetedShareIntents
                        .remove(targetedShareIntents.size() - 1), shareTitle);
                chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
                        targetedShareIntents.toArray(new Parcelable[] {}));
                return chooserIntent;
            }
        }

        return Intent.createChooser(prototype,
                getString(R.string.offer_share_via));
    }

它几乎与 Makibo 发布的解决方案相同，但添加了一些内容，以便通过添加名称来选择您想要共享的应用程序，这样您就不会遇到任何问题，以防他们更改包名称或其他内容像这样。只要他们不改名字就好。

我的自定义开放选择器的实现。

特点：

应用程序按字母顺序排序
处理用户定义的默认应用程序
处理没有应用程序的情况
过滤自身

public static Intent createOpenFileIntent(Context context, String pathToFile) {
    File file = new File(pathToFile);
    String extension = extensionFromName(file.getName());
    String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
    if (mimeType == null) {
        //If android doesn't know extension we can check our own list.
        mimeType = KNOWN_MIME_TYPES.get(DataViewHelper.extensionFromName(file.getName()));
    }

    Intent openIntent = new Intent();
    openIntent.setAction(android.content.Intent.ACTION_VIEW);
    openIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    openIntent.setDataAndType(Uri.fromFile(file), mimeType);

    // 1. Check if there is a default app opener for this type of content.
    final PackageManager packageManager = context.getPackageManager();
    ResolveInfo defaultAppInfo = packageManager.resolveActivity(openIntent, PackageManager.MATCH_DEFAULT_ONLY);
    if (!defaultAppInfo.activityInfo.name.endsWith("ResolverActivity")) {
        return openIntent;
    }

    // 2. Retrieve all apps for our intent. If there are no apps - return usual already created intent.
    List<Intent> targetedOpenIntents = new ArrayList<Intent>();
    List<ResolveInfo> appInfoList = packageManager.queryIntentActivities(openIntent, PackageManager.MATCH_DEFAULT_ONLY);
    if (appInfoList.isEmpty()) {
        return openIntent;
    }

    // 3. Sort in alphabetical order, filter itself and create intent with the rest of the apps.
    Collections.sort(appInfoList, new Comparator<ResolveInfo>() {
        @Override
        public int compare(ResolveInfo first, ResolveInfo second) {
            String firstName = packageManager.getApplicationLabel(first.activityInfo.applicationInfo).toString();
            String secondName = packageManager.getApplicationLabel(second.activityInfo.applicationInfo).toString();
            return firstName.compareToIgnoreCase(secondName);
        }
    });
    for (ResolveInfo appInfo : appInfoList) {
        String packageName = appInfo.activityInfo.packageName;
        if (packageName.equals(context.getPackageName())) {
            continue;
        }

        Intent targetedOpenIntent = new Intent(android.content.Intent.ACTION_VIEW)
                .setDataAndType(Uri.fromFile(file), mimeType)
                .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
                .setPackage(packageName);
        targetedOpenIntents.add(targetedOpenIntent);
    }
    Intent chooserIntent = Intent.createChooser(targetedOpenIntents.remove(targetedOpenIntents.size() - 1), context.getString(R.string.context_menu_open_in))
            .putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedOpenIntents.toArray(new Parcelable[] {}));

    return chooserIntent;
}

public static String extensionFromName(String fileName) {
    int dotPosition = fileName.lastIndexOf('.');

    // If extension not present or empty
    if (dotPosition == -1 || dotPosition == fileName.length() - 1) {
        return "";
    } else {
        return fileName.substring(dotPosition + 1).toLowerCase(Locale.getDefault());
    }
}

Answer 5

我试图用 ShareActionProvider 做同样的事情。 gumbercules 帖子中的方法不适用于 ShareActionProvider，因此我复制并修改了 ShareActionProvider 相关类以允许自定义过滤 ShareActionProvider 建议。

唯一的变化是 ActivityChooserModel.loadActivitiesIfNeeded() 方法。就我而言，我想过滤掉 YouTube 包。

public static final String YOUTUBE_PACKAGE = "com.google.android.youtube";

private boolean loadActivitiesIfNeeded() {
    if (mReloadActivities && mIntent != null) {
        mReloadActivities = false;
        mActivities.clear();
        List<ResolveInfo> resolveInfos = mContext.getPackageManager()
                .queryIntentActivities(mIntent, 0);
        final int resolveInfoCount = resolveInfos.size();
        for (int i = 0; i < resolveInfoCount; i++) {
            ResolveInfo resolveInfo = resolveInfos.get(i);
            // Filter out the YouTube package from the suggestions list
            if (!resolveInfo.activityInfo.packageName.equals(YOUTUBE_PACKAGE)) {
                mActivities.add(new ActivityResolveInfo(resolveInfo));
            }
        }
        return true;
    }
    return false;
}

Answer 6

此解决方案基于这篇文章https://rogerkeays.com/how-to-remove-the-facebook-android-sharing-intent

// get available share intents
final String packageToBeFiltered = "com.example.com"
List<Intent> targets = new ArrayList<Intent>();
Intent template = new Intent(Intent.ACTION_SEND);
template.setType("text/plain");
List<ResolveInfo> candidates = this.getPackageManager().queryIntentActivities(template, 0);

// filter package here
for (ResolveInfo candidate : candidates) {
    String packageName = candidate.activityInfo.packageName;
    if (!packageName.equals(packageToBeFiltered)) {
    Intent target = new Intent(android.content.Intent.ACTION_SEND);
    target.setType("text/plain");
    target.putExtra(Intent.EXTRA_TEXT, "Text to share"));
    target.setPackage(packageName);
    targets.add(target);
   }
}
if (!targets.isEmpty()) {
Intent chooser = Intent.createChooser(targets.get(0), "Share dialog title goes here"));
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, targets.toArray(new Parcelable[]{}));
startActivity(chooser);
}

Answer 7

对于 Kotlin 用户，如果您的目标是 API 24，则此代码对我有用，您应该使用

Intent.EXTRA_EXCLUDE_COMPONENTS

而不是

Intent.EXTRA_INITIAL_INTENTS

，默认情况下会忽略

    @RequiresApi(Build.VERSION_CODES.N)
private fun goToEmailFilteredApps(email: String) {

    val intent = Intent(Intent.ACTION_SEND)
    intent.setTypeAndNormalize("message/rfc822")
    intent.putExtra(Intent.EXTRA_EMAIL, arrayOf(email))

    val chooser = Intent.createChooser(intent, "Send email")

  val emailAppsPackageNames = arrayListOf(
        "com.google.android.gm",                // Gmail
        "com.microsoft.office.outlook",         // Outlook
        "com.yahoo.mobile.client.android.mail", // Yahoo Mail
        "pl.onet.poczta",                       // Onet Mail
        "pl.interia.poczta_next",               // Interia Mail
        "pl.wp.pocztao2",                       // o2 Mail
        "pl.wp.wppoczta",                       // WP  Mail
    )
    val targets = ArrayList<ComponentName>()
    try {
        val queries = requireActivity().packageManager.queryIntentActivities(intent, 0)
        for (candidate in queries) {
            val packageName = candidate.activityInfo.packageName
            if (!emailAppsPackageNames.contains(packageName.lowercase())) {
                targets.add(ComponentName(packageName, candidate.activityInfo.name))
            }
        }
        chooser.putExtra(Intent.EXTRA_EXCLUDE_COMPONENTS, targets.toTypedArray())
        startActivity(chooser)
    } catch (_: ActivityNotFoundException) {
    }
}

这是结果
