Question

所以我正在尝试自定义通过Intent.ACTION_SEND显示的应用程序，除了WeChat和UrlToPDF之外，它的效果非常好。它不是“微信”，而是显示为“Android-System”。如果我点击它，它会打开另一个意图，其中wechat-app显示正确，但没有其他应用程序。我做错了什么？

以下是代码：

shareIntent = new Intent(Intent.ACTION_SEND);

shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_DOCUMENT);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, forecastStr+" #SunshineApp");

final PackageManager pm = getActivity().getPackageManager();
final List<ResolveInfo> resInfo = pm.queryIntentActivities(shareIntent, 0);

ArrayList <String> packageAllowed = new ArrayList();
packageAllowed.add("com.twitter.android");
packageAllowed.add("com.facebook.katana");
packageAllowed.add("com.google.android.gm");
packageAllowed.add("com.whatsapp");
packageAllowed.add("com.evernote");
packageAllowed.add("ch.threema.app");
packageAllowed.add("com.skype.raider");
packageAllowed.add("com.tencent.mm");
packageAllowed.add("com.tencent.mm.ui.tools.ShareToTimeLineUI");

ArrayList <String> packageSum = new ArrayList();

if (!resInfo.isEmpty()) {
    List<Intent> targetedShareIntents = new ArrayList<Intent>();
    for (ResolveInfo resolveInfo : resInfo) {
        String packageName = resolveInfo.activityInfo.packageName;

        if(packageAllowed.contains(packageName)){
            Intent intent=new Intent();
            intent.setAction(Intent.ACTION_SEND);
            intent.setType("text/plain");
            intent.putExtra(Intent.EXTRA_TEXT, "Text");
            intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");

            intent.setPackage(packageName);
            targetedShareIntents.add(intent);
        }
    }

    int size = targetedShareIntents.size();
    Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(targetedShareIntents.size()-1), "Share");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
    startActivity(chooserIntent);
}

尝试另外设置组件名称：

if(packageAllowed.contains(packageName)){
    Intent intent=new Intent();
    intent.setAction(Intent.ACTION_SEND);
    intent.setType("text/plain");
    intent.putExtra(Intent.EXTRA_TEXT, "Text");
    intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");

    // This is new!!!
    intent.setComponent(new ComponentName(packageName, resolveInfo.activityInfo.name)); 

    intent.setPackage(packageName);
    targetedShareIntents.add(intent);
}

Android：自定义后没有显示一些共享意图（微信，Url2Pdf）
