我正在尝试使用图形 API 在 Facebook 墙上发布一些内容，但它对我不起作用。它没有错误，但也没有在我的墙上发布任何内容。
这是代码：
public class ActivityName extends Activity{
Dialog dialog;
Facebook fb;
SharedPreferences sp;
String access_token, name, email;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.success);
String APP_ID = "MY_ID";
fb = new Facebook(APP_ID);
sp = getPreferences(MODE_PRIVATE);
access_token = sp.getString("access_token", null);
long expires = sp.getLong("access_expires", 0);
if(access_token!= null){
fb.setAccessToken(access_token);
}
if(expires != 0){
fb.setAccessExpires(expires);
}
((Button) findViewById(R.id.btn_home)).setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
openContextMenu(v);
}
});
((Button) findViewById(R.id.btn_home)).setOnCreateContextMenuListener(new View.OnCreateContextMenuListener() {
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
menu.setHeaderTitle("Tell the world!");
menu.add(0, 0, 0, "Facebook");
menu.add(0, 1, 0, "Twitter");
menu.add(0, 2, 0, "Skip");
}
});
}
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
.getMenuInfo();
switch (item.getItemId()) {
case 1:
break;
case 0:
fb.authorize(SuccessActivity.this, new String[]{ "photo_upload,user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() {
public void onComplete(Bundle values) {
postToWall();
}
public void onFacebookError(FacebookError error) {
}
public void onError(DialogError e) {
}
public void onCancel() {
}
});
break;
case 2:
Intent i = new Intent(getApplicationContext(),MainActivity.class);
startActivity(i);
overridePendingTransition(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
break;
}
return true;
}
public void onBackPressed() {
}
@SuppressLint("SdCardPath")
public void postToWall() {
// post on user's wall.
try {
if (fb.isSessionValid()) {
byte[] data = null;
Bitmap bi = BitmapFactory.decodeFile("/sdcard/Asa.jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();
Bundle params = new Bundle();
params.putString(Facebook.TOKEN, fb.getAccessToken());
params.putString("message", "Test from Android AVD");
params.putByteArray("picture", data);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(fb);
mAsyncRunner.request("/me/feed", params,"POST", new SampleUploadListener(),null);
}
}catch(Exception e){
e.printStackTrace();
}
}
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
// e.g. "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) {
}
}
}
任何人都可以在此代码中找出缺失或错误的地方吗？任何想法将不胜感激。
