Question

我使用以下代码在facebook，twitter，google +和其他社交应用上分享图片。图像从设备的外部存储上传。但是，当我在那里显示选择器时，会有多人脸书和推特图标。如何限制只显示一个图标？以下是代码。

public void customShare() {
    if (file.exists()) {
        Uri uri = Uri.fromFile(file);
        List<Intent> targetedShareIntents = new ArrayList<Intent>();
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("image/jpeg");
        intent.putExtra(Intent.EXTRA_STREAM, uri);
        List<ResolveInfo> resInfo = this.getPackageManager().queryIntentActivities(intent, 0);

        for (ResolveInfo resolveInfo : resInfo) {
            String packageName = resolveInfo.activityInfo.packageName;
            Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
            targetedShareIntent.setType("image/jpeg");
            targetedShareIntent.putExtra(Intent.EXTRA_STREAM, uri);
            targetedShareIntent.setPackage(packageName);
            if (packageName.equals("com.facebook.katana")  || packageName.equals("ru.ok.android") ||
                   packageName.equals("com.vkontakte.android") || packageName.equals("com.twitter.android")||
                    packageName.equals("com.whatsapp") || packageName.equals("org.telegram.messenger") ||
                    packageName.equals("com.google.android.apps.plus")) {

                targetedShareIntents.add(targetedShareIntent);
            }
        }
        Intent chooserIntent = Intent.createChooser(
                targetedShareIntents.remove(0), "");

        chooserIntent.putExtra(
                Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
        startActivity(chooserIntent);
    }
}

这是选择器上显示的内容。

Answer 1

 List<Intent> targetedShareIntents = new ArrayList<Intent>();
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("image/jpeg");
        intent.putExtra(Intent.EXTRA_STREAM, uri);
        List<ResolveInfo> resInfo = this.getPackageManager().queryIntentActivities(intent, 0);

上面的代码重新调整了所有具有操作类型Intent.ACTION_SEND的活动.Facebook有多种活动，此类型简单，因此resInfo 有多个具有相同packagename值的条目com.facebook.katana。使用resolveInfo.activityInfo.targetActivity检查包含所有条目的活动

 for (ResolveInfo resolveInfo : resInfo) {
            String packageName = resolveInfo.activityInfo.packageName;


            Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
            targetedShareIntent.setType("image/jpeg");
            targetedShareIntent.putExtra(Intent.EXTRA_STREAM, uri);
            targetedShareIntent.setPackage(packageName);
            if (packageName.equals("com.facebook.katana") || packageName.equals("ru.ok.android") ||
                    packageName.equals("com.vkontakte.android") || packageName.equals("com.twitter.android") ||
                    packageName.equals("com.whatsapp") || packageName.equals("org.telegram.messenger") ||
                    packageName.equals("com.google.android.apps.plus")) {

                Log.d("PackageAdded", packageName+"  = ====== "+ resolveInfo.activityInfo.targetActivity);
                targetedShareIntents.add(targetedShareIntent);
            }
        }

对于解决方案，您只需删除已添加到targetedShareIntents的现有包。
