限制股票期权

Question

有办法限制Android应用程序中的共享选项吗？我尝试过使用ShareActionProvider，或者只是使用Intent启动一个意图。ACTION_SEND意图选项。基本上，我希望能够仅通过电子邮件或类似的方式限制共享。

你可以根据你的需要定制意图选择器，就像这样-

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 (StringUtils.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[]{}));

            startActivity(chooserIntent);
        }

希望这对你有帮助。

你可以用这样的东西，但是不要用脸谱网，找一个不同的名字

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT,"this is a string");
shareIntent.setType("image/png");
shareIntent.putExtra(android.content.Intent.EXTRA_STREAM,uri); //Share the image on Facebook
PackageManager pm = getApplicationContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
                    for (final ResolveInfo app : activityList) {
                        if ((app.activityInfo.name).contains("facebook")) {
                            final ActivityInfo activity = app.activityInfo;
                            final ComponentName name = new ComponentName(
                                        activity.applicationInfo.packageName,
                                        activity.name);
                            shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
                            shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
                                | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
                            shareIntent.setComponent(name);
                            startActivity(shareIntent);
                            break;
                                }
                            }
