【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"
/>

3.添加监听事件即可

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
}
