android - 如何在 android 中使用 Graph API 在 facebook 上发布我的状态

Question

我想在我的 android 应用程序中使用 Graph API 来使用我的 android 应用程序发布文本状态，但不知道如何完美地使用 API...(我正在使用最新的 API)

这是我的登录 Activity

import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.Toast;

import com.facebook.AccessToken;
import com.facebook.CallbackManager;
import com.facebook.FacebookCallback;
import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.appevents.AppEventsLogger;
import com.facebook.login.LoginResult;
import com.facebook.login.widget.LoginButton;

import java.util.Arrays;


public class LoginToFacebook extends AppCompatActivity {

    public LoginButton loginButton;
    private CallbackManager callbackManager;
    public static final String LOGGED_IN_PREFFERENCE = "loggedInPrefference" ;
    private AccessToken accessToken;
    LoginResult loginResultOfClass;
    static SharedPreferences mPrefs;

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        if(mPrefs.getBoolean("loggedIn",false)==true);
        {
            Intent i = new Intent(LoginToFacebook.this,PostToWall.class);
            startActivity(i);


        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getApplicationContext());
        mPrefs = getSharedPreferences(LOGGED_IN_PREFFERENCE, Context.MODE_PRIVATE);
        callbackManager = CallbackManager.Factory.create();
        accessToken = AccessToken.getCurrentAccessToken();

        setContentView(R.layout.activity_login_to_facebook);
        loginButton = (LoginButton) findViewById(R.id.login_button);
        loginButton.setReadPermissions(Arrays.asList("user_friends"));


        // Other app specific specialization




        // Callback registration
        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {
                // App code

                loginResultOfClass = loginResult;

                SharedPreferences.Editor editor = mPrefs.edit();
                editor.putBoolean("loggedIn",true);
                editor.commit();


                Intent i = new Intent(LoginToFacebook.this,PostToWall.class);
                i.putExtra("UserName", loginResult.getAccessToken().getUserId());
                i.putExtra("AuthToken", loginResult.getAccessToken().getToken());
                startActivity(i);
            }

            @Override
            public void onCancel() {
                // App code

                Toast.makeText(LoginToFacebook.this, "login Cancelled", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError(FacebookException exception) {
                // App code
                Toast.makeText(LoginToFacebook.this, "login exception"+exception.toString(), Toast.LENGTH_SHORT).show();

            }
        });




    }





    @Override
    protected void onResume() {
        super.onResume();
        // Logs 'install' and 'app activate' App Events.
        AppEventsLogger.activateApp(this);
    }


    @Override
    protected void onPause() {
        super.onPause();
        // Logs 'app deactivate' App Event.
        AppEventsLogger.deactivateApp(this);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }


}

这是我想发布状态的 Activity

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;

import com.facebook.GraphResponse;
import com.facebook.HttpMethod;
import com.facebook.login.widget.LoginButton;

import org.json.JSONException;
import org.json.JSONObject;

import java.util.Arrays;

public class PostToWall extends AppCompatActivity {
    TextView info;
    private LoginButton loginButton;
    private EditText post_text;
    Button post_button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getApplicationContext());
        setContentView(R.layout.activity_post_to_wall);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        post_text = (EditText)findViewById(R.id.post_text);
        post_button = (Button) findViewById(R.id.post_button);

        loginButton = (LoginButton) findViewById(R.id.login_button);
        loginButton.setPublishPermissions(Arrays.asList("publish_actions"));


        setSupportActionBar(toolbar);
        info = (TextView) findViewById(R.id.info);
        Intent i = getIntent();
        info.setText(i.getStringExtra("UserName") + i.getStringExtra("AuthToken"));

post_button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {


        Bundle params = new Bundle();
        params.putString("message", "hello post");
        JSONObject jsonObject = new JSONObject();
        try {
            jsonObject.put("value", "SELF");
        } catch (JSONException e) {
            e.printStackTrace();
        }
        params.putString("privacy", jsonObject.toString());

/* make the API call */

        GraphRequest request = new GraphRequest();
        request.setAccessToken(AccessToken.getCurrentAccessToken());
        request.setHttpMethod(HttpMethod.POST);

        request.setParameters(params);

        request.setGraphPath("/me/feed");
        request.setCallback(new GraphRequest.Callback() {
            @Override
            public void onCompleted(GraphResponse response) {

                Toast.makeText(PostToWall.this, "Post Success", Toast.LENGTH_SHORT).show();


            }
        });

        request.executeAsync();



    }
});

    }


}

我不知道为什么 GraphRequest 对我不起作用...帮我找出我的错误...

请尝试以下代码:

Bundle postContents = new Bundle();
            String selectedImageURL = galleryObj.getImageURL(mImageSelected);
            mImageStory = mTextBox.getText().toString();

            /*postContents.putString("attachment", "{\"name\":\""+mImageStory+"\","
            +"\"media\":[{\"type\":\"image\",\"src\":\""+selectedImageURL+"\",\"href\":\""+selectedImageURL+"\"}]"
            +"}");*/

//Below code is for posting text only
postContents.putString("attachment", "{\"name\":\""+mImageStory+"\""
            +"}");

            // OLD REST API stream.publish used to publish data onto the wall
            mFacebook.dialog(mContext, "stream.publish", postContents, new AndroidDialogListener());

以下是用于在墙上发布带有文本的图像的监听器:

public class AndroidDialogListener extends BaseDialogListener {

    public void onComplete(Bundle values) {
        final String postId = values.getString("post_id");
        if (postId != null) {
            Log.d("Facebook-Example", "Dialog Success! post_id=" + postId);

            // get the post id and send a request to get it posted on wall
            // once posted/failure then call back invoked
            mAsyncRunner.request(postId, new WallPostRequestListener());

        } else {
            Log.d("Facebook-Example", "No wall post made");
        }
    }
}
