在Android中使用Facebook Android SDK将照片上传到Facebook

我是Android新手。 我正在寻找通过授权加载Facebook的照片，获取access_token。 如何做到这一点？ 请给我一个Java代码示例。

Answer 1

刚刚在这里发布上传照片的简单方法：

android facebook发布照片

码：

byte[] data = null; Bitmap bi = BitmapFactory.decodeFile(photoToPost); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bi.compress(Bitmap.CompressFormat.JPEG, 100, baos); data = baos.toByteArray(); Bundle params = new Bundle(); params.putString("method", "photos.upload"); params.putByteArray("picture", data); AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook); mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);

 facebook.authorize(FbdemoActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() { @Override public void onComplete(Bundle values) { } @Override public void onFacebookError(FacebookError error) { } @Override public void onError(DialogError e) { } @Override public void onCancel() { } }); public void postImageonWall() { byte[] data = null; Bitmap bi = BitmapFactory.decodeFile("/sdcard/viewitems.png"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bi.compress(Bitmap.CompressFormat.JPEG, 100, baos); data = baos.toByteArray(); Bundle params = new Bundle(); params.putString(Facebook.TOKEN, facebook.getAccessToken()); params.putString("method", "photos.upload"); params.putByteArray("picture", data); AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook); mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null); } public class SampleUploadListener extends BaseRequestListener { public void onComplete(final String response, final Object state) { try { // process the response here: (executed in background thread) Log.d("Facebook-Example", "Response: " + response.toString()); JSONObject json = Util.parseJson(response); final String src = json.getString("src"); // then post the processed result back to the UI thread // if we do not do this, an runtime exception will be generated // eg "CalledFromWrongThreadException: Only the original // thread that created a view hierarchy can touch its views." } catch (JSONException e) { Log.w("Facebook-Example", "JSON Error in response"); } catch (FacebookError e) { Log.w("Facebook-Example", "Facebook Error: " + e.getMessage()); } } @Override public void onFacebookError(FacebookError e, Object state) { // TODO Auto-generated method stub } } 

这里是整个代码尝试它，它肯定会为你工作，这也是我的工作

最简单的方法是使用现有的SDK，就像这样：
http://github.com/facebook/facebook-android-sdk/
http://code.google.com/p/fbconnect-android/
http://wiki.developers.facebook.com/index.php/User:Android

更灵活的方法是自己实现API，这里是有用的文档：

如果您想发布带有说明的照片，可以这样做：

 public void publishPhoto(byte[] imgData, string message) { AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner (facebook); Bundle parameters = new Bundle (); parameters.putString (Facebook.TOKEN, facebook.getAccessToken()); parameters.putString ("message", message); parameters.putByteArray ("source", imgData); mAsyncRunner.Request ("me/photos", parameters, "POST", new RequestListener (), null); }

成功地，我已经上传在Facebook墙上的照片我用下面的代码。

在您的主要活动中执行以下操作;

 btn1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub authenticatedFacebook.authorize(Facebooktest2Activity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() { @Override public void onComplete(Bundle values) { postImage(); Toast.makeText(getApplicationContext(), "Image Posted on Facebook.", Toast.LENGTH_SHORT).show(); } @Override public void onFacebookError(FacebookError error) { } @Override public void onError(DialogError e) { } @Override public void onCancel() { } }); } }); } public void postImage(){ byte[] data = null; Bitmap bi = BitmapFactory.decodeFile("/sdcard/img.jpg"); //Bitmap bi = BitmapFactory.decodeResource(getResources(), R.drawable.icon); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bi.compress(Bitmap.CompressFormat.JPEG, 100, baos); data = baos.toByteArray(); Bundle params = new Bundle(); params.putString(Facebook.TOKEN, authenticatedFacebook.getAccessToken()); params.putString("method", "photos.upload"); params.putByteArray("picture", data); AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(authenticatedFacebook); mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null); } public class SampleUploadListener extends BaseKeyListener implements RequestListener { public void onComplete(final String response, final Object state) { try { // process the response here: (executed in background thread) Log.d("Facebook-Example", "Response: " + response.toString()); JSONObject json = Util.parseJson(response); final String src = json.getString("src"); // then post the processed result back to the UI thread // if we do not do this, an runtime exception will be generated // eg "CalledFromWrongThreadException: Only the original // thread that created a view hierarchy can touch its views." } catch (JSONException e) { Log.w("Facebook-Example", "JSON Error in response"); } catch (FacebookError e) { Log.w("Facebook-Example", "Facebook Error: " + e.getMessage()); } } public void onFacebookError(FacebookError e, Object state) { // TODO Auto-generated method stub } public Bitmap getInputType(Bitmap img) { // TODO Auto-generated method stub return img; } @Override public int getInputType() { // TODO Auto-generated method stub return 0; } @Override public void onIOException(IOException e, Object state) { // TODO Auto-generated method stub } @Override public void onFileNotFoundException(FileNotFoundException e, Object state) { // TODO Auto-generated method stub } @Override public void onMalformedURLException(MalformedURLException e, Object state) { // TODO Auto-generated method stub } } 

当然这个代码会帮助你。
