分享至Facebook，通过共享意图的android微博 [英] Sharing to facebook, twitter via share intent android

问题描述

目前我正在试图分享文字到Gmail，Facebook和Twitter。我使用份额的意图的方法来共享。下面是code I用于共享

I am currently trying to share text to gmail, facebook and twitter. I am using share intent method to share. Below is the code i used to share

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
       sharingIntent.setType("plain/text");
       sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "My text");
       startActivity(Intent.createChooser(sharingIntent,"Share using"));

以上code只能说明，如Gmail和Skype的股权。为什么Facebook和Twitter选项不显示在列表中，即使我已经安装在我的设备的Facebook和Twitter的应用程序？

The above code only show share options like gmail and skype. Why is facebook and twitter options not shown in the list even though i had the facebook and twitter application installed in my device?

推荐答案

我不知道是否有人还在读这一点，但如果人们仍然在寻找我发现了一个简单的答案：

I don't know if anybody still reads this, but if people are still looking I found an easier answer:

List<Intent> targetedShareIntents = new ArrayList<Intent>();

Intent facebookIntent = getShareIntent("facebook", "subject", "text");
if(facebookIntent != null)
    targetedShareIntents.add(facebookIntent);

Intent twitterIntent = getShareIntent("twitter", "subject", "text");
    if(twitterIntent != null)
        targetedShareIntents.add(twitterIntent);

Intent gmailIntent = getShareIntent("gmail", "subject", "text");
    if(gmailIntent != null)
        targetedShareIntents.add(gmailIntent);

Intent chooser = Intent.createChooser(targetedShareIntents.remove(0), "Delen");

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

startActivity(chooser);

而getShareIntent方法（通过MIME类型text这种方法搜索/平，可以使用其他MIME类型，通过这些类型搜索或使用/ * /通过各类搜索：

And the getShareIntent method (this method searches through the mime type text/plain, you can use other mime types to search through those types or use /*/ to search through all types:

private Intent getShareIntent(String type, String subject, String text) 
{
    boolean found = false;
    Intent share = new Intent(android.content.Intent.ACTION_SEND);
    share.setType("text/plain");

    // gets the list of intents that can be loaded.
    List<ResolveInfo> resInfo = getActivity().getPackageManager().queryIntentActivities(share, 0);
    System.out.println("resinfo: " + resInfo);
    if (!resInfo.isEmpty()){
        for (ResolveInfo info : resInfo) {
            if (info.activityInfo.packageName.toLowerCase().contains(type) || 
                    info.activityInfo.name.toLowerCase().contains(type) ) {
                share.putExtra(Intent.EXTRA_SUBJECT,  subject);
                share.putExtra(Intent.EXTRA_TEXT,     text);
                share.setPackage(info.activityInfo.packageName);
                found = true;
                break;
            }
        }
        if (!found)
            return null;

        return share;
    }
    return null;
}

如果你不想使用此方法，你可以创建这样的意图：

If you don't want to use this method you can just create Intents like this:

Intent normalIntent = new Intent(Intent.ACTION_SEND);
normalIntent.setType("text/plain");
normalIntent.setPackage("com.katana.facebook"); // I just know the package of Facebook, the rest you will have to search for or use my method.
normalIntent.putExtra(Intent.EXTRA_TEXT, "The text you want to share to Facebook");
