Question

如果我使用ACTION_SEND的Intent并输入“text / plain”并且EXTRA_TEXT Facebook不预先填充任何内容。这是我已经看到的东西。每个人都说，使用Facebook SDK，但我不希望我的应用程序自动发布任何内容，也不希望我的应用程序处理登录令牌。我只想要使用预定义的文本，链接和图像打开Write Post Facebook屏幕。就像我从Gallery应用程序共享图像一样。有可能吗？

好的，通过Intent无法做到这一点。显示文本，图像+链接并让用户在发布之前编写内容的唯一解决方案是使用丑陋的Feed对话框（或使用EditText创建自定义活动，用户可以在其中编写内容）。

以下是有效的代码：

public class FacebookPostActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_facebook_post);

    Session.openActiveSession(this, false, new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state, Exception exception) {
            if(session.isOpened()){
                publishFeedDialog();
            }
        }
    });
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

private void publishFeedDialog() {
    Bundle params = new Bundle();
    params.putString("name", "Facebook SDK for Android");
    params.putString("caption", "Build great social apps and get more installs.");
    params.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
    params.putString("link", "https://developers.facebook.com/android");
    params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

    WebDialog feedDialog = new WebDialog.FeedDialogBuilder(this, Session.getActiveSession(), params)
            .setOnCompleteListener(new OnCompleteListener() {
                @Override
                public void onComplete(Bundle values, FacebookException error) {
                    if(error == null){
                        final String postId = values.getString("post_id");
                        if(postId != null){
                            Toast.makeText(FacebookPostActivity.this, "Posted story, id: " + postId, Toast.LENGTH_SHORT).show();
                        }else{
                            Toast.makeText(FacebookPostActivity.this, "Publish cancelled", Toast.LENGTH_SHORT).show();
                        }
                    }else if(error instanceof FacebookOperationCanceledException){
                        // User clicked the "x" button
                        Toast.makeText(FacebookPostActivity.this, "Publish cancelled", Toast.LENGTH_SHORT).show();
                    }else{
                        // Generic, ex: network error
                        Toast.makeText(FacebookPostActivity.this, "Error posting story", Toast.LENGTH_SHORT).show();
                    }
                }
            }).build();

    feedDialog.show();
}

}
