问题描述
我有一个片段,尝试使用Volley API实例化新的newRequestQueue
.
I have an fragment where I try to Instantiate a new newRequestQueue
with the Volley API.
我尝试这样实例化它:
RequestQueue queue = Volley.newRequestQueue(this);
但是,当我尝试创建请求时,出现以下错误:
However, when I try to create the request, I get the following error:
newRequestQueue In Volley cannot be applied to annonymous android.view.View.OnClickListener
这是我的Fragment类:
Here is my Fragment class:
public class LoginFragment extends Fragment {
private FacebookLogin fLogin;
private Profile profile;
private CallbackManager mCallbackManager; //Used in activity result below. Gets a value when u hit the button
private static final String TAG = "Event";
private static String url_create_user = "127.0.0.1/create_row.php";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fLogin = new FacebookLogin(getActivity().getApplicationContext());
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.login, container, false);
return v;
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
final LoginButton loginButton = (LoginButton) getView().findViewById(R.id.login_button);
final TextView infoText = (TextView) getView().findViewById(R.id.text_details);
final ImageView profilP = (ImageView) getView().findViewById(R.id.profilePicture);
loginButton.setFragment(this);
loginButton.setReadPermissions("user_friends");
loginButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.i(TAG, " Button clickde");
fLogin.setCallback(loginButton); //Let's register a callback
RequestQueue queue = Volley.newRequestQueue(this);
fLogin.setFacebookListener(new FacebookLogin.OnFacebookListener() {
@Override
public void onFacebookLoggedIn(JSONObject parameters) {
Log.i(TAG, "INNNNNNNNNNNE");
Log.i(TAG, parameters.toString());
}
});
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mCallbackManager = fLogin.getCallbackManager(); //Get the callbackmanager
mCallbackManager.onActivityResult(requestCode, resultCode, data);
}
}
推荐答案
newRequestQueue
的参数是一个Context对象.在您的情况下,这指的是View.OnClickListener
匿名内部类,您在其中调用newRequestQueue
.更改
the parameter of newRequestQueue
is a Context object. In your case, this, refers to the View.OnClickListener
anonymous inner class, where you are calling newRequestQueue
. Change
Volley.newRequestQueue(this);
使用
Volley.newRequestQueue(getActivity().getApplicationContext());
当然,
是getActivity()
,因为您是Fragment
is, of course, getActivity()
because you are subclassing Fragment
