【FacebookSDK学习笔记】Facebook消息分享

1.手机上要安装了Facebook Message才能使用这个功能

Google Play网址：https://play.google.com/store/apps/details?id=com.facebook.orca

2.直接添加一个button

 <Button
    android:id="@+id/messageButton"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textStyle="bold"
    android:gravity="center"
    android:layout_marginTop="30dp"
    android:visibility="invisible"
    android:text="message"
   />

FacebookDialog.MessageDialogBuilder builder = new FacebookDialog.MessageDialogBuilder(getActivity())
		    .setLink("https://developers.facebook.com/docs/android/share/")
		    .setName("Message Dialog Tutorial")
		    .setCaption("Build great social apps that engage your friends.")
		    .setPicture("http://i.imgur.com/g3Qc1HN.png")
		    .setDescription("Allow your users to message links from your app using the Android SDK.")
		    .setFragment(this);

		// If the Facebook app is installed and we can present the share dialog
		if (builder.canPresent()) {
		  // Enable button or other UI to initiate launch of the Message Dialog
			FacebookDialog dialog = builder.build();
			dialog.present();
		}  else {
		  // Disable button or other UI for Message Dialog 
			Log.e("===Error===","Error!No Message!");//出现此log说明未安装Messager
		}

如下图：
