通过程序包名称为共享意图创建自定义选择器 [英] Creating custom chooser for share intent by package name

问题描述

我的android活动中有一个Text，我想给用户选项以在社交应用(例如whatsapp，line，facebook，twitter等)上共享该文本.

I have a Text in my android activity and I want give the user option to share it on social apps like whatsapp, line, facebook, twitter etc.

但是我想创建一个自定义选择器，以使其不会在选择器中显示意外的应用程序.

But I want to create a custom chooser so that it won't show unintended apps in the chooser.

我知道此代码段

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
startActivity(Intent.createChooser(shareIntent, "Share via"));

如何做到这一点，以便在选择器中仅显示我可以通过程序包名称指定的应用程序.

How can I make it so that in the chooser it'd only show the apps which I can specify by their package names.

谢谢

推荐答案

即使我认为这个问题是重复的，但是由于我仍然找不到重复的问题，所以让我先提供一个答案.

Even though I think this question is duplicated, but since I can't find the duplicated question yet, let me provide an answer first.

List<Intent> targetedShareIntents = new ArrayList<Intent>();
Intent shareInent = new Intent(Intent.ACTION_SEND);
shareInent.setType("text/plain");
List<ResolveInfo> resInfo = activity.getPackageManager().queryIntentActivities(shareInent, 0);
// put the name of the packages you want in this ArrayList
ArrayList<String> wantedPackage = new ArrayList<>();

if (!resInfo.isEmpty()) {
    for (ResolveInfo info : resInfo) {
        Intent targetedShare = new Intent(android.content.Intent.ACTION_SEND);
        targetedShare.setType("text/plain");
        String infoPackageName = info.activityInfo.packageName.toLowerCase();

        if (wantedPackage.contains(infoPackageName)) {
            targetedShare.putExtra(Intent.EXTRA_TEXT, "put your text here");
            targetedShare.setPackage(info.activityInfo.packageName.toLowerCase());
            targetedShareIntents.add(targetedShare);
            resPackageNames.add(infoPackageName);
        }
    }
    Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Chooser title");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
    startActivity(chooserIntent);
}
