推荐答案

您可以简单地做，没有使用Facebook的SDK安装在手机的Facebook应用程序的帮助。只要遵循这些简单的步骤

You can simply do that without using Facebook SDK with the help of facebook app installed in your phone. Just follow these simple steps

所以，首先，你得把你的应用程序的截图在这样的位图的形式

So first of all, you have to take screenshot of your app in the form of bitmap like this

View v1 = yourScreenShotView.getRootView();  
v1.setDrawingCacheEnabled(true);
Bitmap bitmap= v1.getDrawingCache();

在你从上面然后得到位图你必须做出这样的位图的URI

After you get bitmap from above then you have to make uri of the bitmap like this

uri = getImageUri(context, bitmap); 

和这里是你的getImageUriFunction（）

and here is your getImageUriFunction()

public static Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(),
            inImage, "", "");
    return Uri.parse(path);
}

在您得到您的URI，你要使用该功能分享的FB

After you get your uri, you have to share that on fb with this function

share_screen(uri,"facebook");

下面是功能

 public void share_screen(Uri pngUri, final String sharingapp) {

    Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
    shareIntent.setType("image/png");
    shareIntent
            .putExtra(android.content.Intent.EXTRA_TEXT,
                    "your sharing text");
    shareIntent.putExtra(android.content.Intent.EXTRA_STREAM, pngUri); // 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(sharingapp)) {
            c++;
            final ActivityInfo activity = app.activityInfo;
            final ComponentName name = new ComponentName(
                    activity.applicationInfo.packageName, activity.name);
            shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
            shareIntent.setComponent(name);
            startActivity(shareIntent);
            break;
        }

    }
    if (c == 1) 
        c = 0;
     else {
                AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                        context);
                alertDialog.setTitle("Alert");
                alertDialog.setMessage("You don't have " + sharingapp
                        + " installed.");
                alertDialog.setPositiveButton("OK",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int which) {
                                dialog.dismiss();

                            }
                        });
                alertDialog.show();
            }

    }
}
