我有一个应用程序，在某个时候我有一个分享到 Facebook 的选项。我正在使用 Facebook SDK 4。
我想要这个片段做的只是登录到用户的 Facebook 并分享一张图片和一些文字。如果可能的话，我宁愿在没有片段的情况下这样做，但如果没有其他方法，我准备好忽略它。
片段：
public class Facebook extends Fragment {
private CallbackManager mCallBack;
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
private String mParam1;
private String mParam2;
private OnFragmentInteractionListener mListener;
public static Facebook newInstance(String param1, String param2) {
Facebook fragment = new Facebook();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
}
public Facebook() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
mCallBack = CallbackManager.Factory.create();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_facebook, container, false);
}
public void onButtonPressed(Uri uri) {
if (mListener != null) {
mListener.onFragmentInteraction(uri);
}
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mListener = (OnFragmentInteractionListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnFragmentInteractionListener");
}
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton login = (LoginButton) view.findViewById(R.id.loginb);
login.setReadPermissions("user_friends");
login.setFragment(this);
login.registerCallback(mCallBack,mCallBacke);
}
@Override
public void onDetach() {
super.onDetach();
mListener = null;
}
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
public void onFragmentInteraction(Uri uri);
}
private FacebookCallback<LoginResult> mCallBacke=new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();
if(profile!=null){
Toast.makeText(getActivity().getApplicationContext(), "WElbon",
Toast.LENGTH_SHORT).show();
}
Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.redsmall);
SharePhoto photo = new SharePhoto.Builder()
.setBitmap(image)
.build();
SharePhotoContent content = new SharePhotoContent.Builder()
.addPhoto(photo)
.build();
ShareApi.share(content, null);
Toast.makeText(getActivity().getApplicationContext(),"Facebook Photo Upload Complated",Toast.LENGTH_LONG).show();
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException e) {
}
};
我调用片段的 Activity 有 fragmentActivity 扩展（我读到这应该修复它，但它没有）
CallbackManager callbackManager;
ShareDialog shareDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_unlock_braggin_rights);
DisplayMetrics dm = new DisplayMetrics();
int width = dm.widthPixels;
int hight = dm.heightPixels;
//getWindow().setLayout((int) (width * .8), (int) (hight * .5));
Bundle so = getIntent().getExtras();
String ulocked = so.getString("unlocked");
TextView unlocked = (TextView)findViewById(R.id.unlocked);
unlocked.setText(ulocked);
unlocked.setText(ulocked);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_unlock_braggin_rights, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void buttonClicked(View view){
Intent intent = new Intent(this,Store.class);
startActivity(intent);
finish();
}
@Override
public void onBackPressed() {
Intent intent = new Intent(this,Store.class);
startActivity(intent);
finish();
}
错误代码：
