我只想在android中发布facebook sdk的facebook状态更新。 可能吗？ 如果是这样，我该怎么做？
我已经看过facebook对话教程，但是用于分享链接。
FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this)
.setApplicationName("..").setLink("...").setCaption(",,,").setDescription("...").setName("..")
.build();
uiHelper.trackPendingDialogCall(shareDialog.present());
但我可以将一个简单的文字发布到我的Facebook墙上吗？

https://developers.facebook.com/docs/graph-api/reference/v2.1/user/feed
搜索“发布”并点击“Android SDK”以获取示例代码。但请记住，根据策略，消息必须是100％用户生成的：
https://developers.facebook.com/policy/
2.3确保用户输入用户消息参数中的所有内容。不要预填。这包括帖子，消息，评论， 和字幕。

我通过使用“publish_actions”登录然后调用postToWall（）方法来完成这篇文章。它对我有用。我正在使用facebook sdk。
//facebook
compile 'com.facebook.android:facebook-android-sdk:4.18.0'
public void postToWall() {
try {
GraphRequest request = GraphRequest.newPostRequest(AccessToken.getCurrentAccessToken(), "me/feed", null, new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse response) {
Log.d("StatusPost", "STATUS UPDATED SUCESSFULLY " + response.getRawResponse());
}
});
Bundle parameters = new Bundle();
parameters.putString("message", "hellow everyone from newyork");
request.setParameters(parameters);
request.executeAsync();
} catch (Exception e) {
e.printStackTrace();
GlobalApp.printLog("Exception_feed", e.getMessage() + "");
//finish();
}
}
