我将开发一个android应用程序,并尝试分离事物。...我创建了一个FacebookConnect类来调用facebook API,以检索facebook公共信息,以便以后使用它们,但当我的对象为null时我回到了我的主要Java课。
任何想法...我的知识是该技能领域的平均水平。
这是我在FacebookConnect中的功能
public void getConnectionWithFacebook(Activity myActivity, CallbackManager mCallbackManager){
MCALLBACKMANAGER = mCallbackManager;
MYACTIVITY = myActivity;
ONEUSER = new User();
LoginManager.getInstance().logInWithReadPermissions(MYACTIVITY, Arrays.asList("email", "public_profile"));
LoginManager.getInstance().registerCallback(MCALLBACKMANAGER, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.d(TAG,"facebookSuccess3 -> " + loginResult.toString());
// App code
GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.d(TAG,"facebookSuccess4 -> " + response.toString());
getDataFromFacebook(object);
}
});
Bundle parameters = new Bundle();
parameters.putString("fields","id,email,first_name,last_name");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
Log.d(TAG,"facebook -> " + "onCancel");
Toast.makeText(MYACTIVITY, "Une erreur s'est produite, veuillez réessayer plus tard...", Toast.LENGTH_LONG).show();
}
@Override
public void onError(FacebookException error) {
Log.d(TAG,"facebookONError -> " +error.toString());
Toast.makeText(MYACTIVITY, "Une erreur s'est produite, veuillez réessayer plus tard...", Toast.LENGTH_LONG).show();
// ...
}
});
}
在我的主类中,我将在click事件中调用此函数:
btnFBLogin.setOnClickListener(new View.OnClickListener() {
FacebookConnect oneConnection = new FacebookConnect();
@Override
public void onClick(View v) {
btnFBLogin.setEnabled(false);
oneConnection.getConnectionWithFacebook(MainActivity.this, mCallbackManager);
String email = oneConnection.getEmail();
Log.d(TAG,"handleFacebookToken1 -> " + email); // doesnt work
}
});
不幸的是,结果为null或为空,我不知道为什么。
编辑:
这是我的功能,用于将来自Facebook的数据关联到我的班级:
public void getDataFromFacebook(JSONObject object) {
try{
String emailJSON = object.getString("email");
String fristNameJSON = object.getString("first_name");
String lastNameJSON = object.getString("last_name");
Log.d(TAGUSER,"facebookSuccess -> " + emailJSON);
Log.d(TAGUSER,"facebookSuccess -> " + fristNameJSON);
Log.d(TAGUSER,"facebookSuccess -> " + lastNameJSON);
//Log.d(TAGUSER,"facebookSuccess -> " + object.getString("email"));
// Log.d(TAGUSER,"facebookSuccess -> " + object.getString("first_name"));
//Log.d(TAGUSER,"facebookSuccess -> " + object.getString("last_name"));
this.setEmail(emailJSON);
this.setFirstName(fristNameJSON);
this.setLastName(lastNameJSON);
Log.d(TAGUSER,"facebookSuccess -> " + getEmail());
Log.d(TAGUSER,"facebookSuccess -> " + getFirstName());
Log.d(TAGUSER,"facebookSuccess -> " + getLastName());
} catch (JSONException e) {
e.printStackTrace();
}
}
我在每个地方都投入了很多东西来查看数据删除的情况
再次感谢!
