So I am in the middle of a Challenge from a book I am reading. The challenge says that I do some questions at the users of the app and they should answer True or False. Also they have the option to cheat but when they gone back to the question answer must not be acceptable.
So I created a Boolean Array where I save the status of the "cheater". True if he cheats and False if he doesn't cheat. But after one full rotation of the Questions the Array is Wiped. Why is this happening? What I am doing wrong?
Here is my main code for the Quiz Activity:
public class QuizActivity extends Activity {
private Button mTrueButton;
private Button mFalseButton;
private Button mNextButton;
private Button mCheatButton;
private TextView mQuestionTextView;
private static final String TAG = "QuizActivity";
private static final String KEY_INDEX = "index";
private static final String CHEATER_BOOLEAN = "cheat";
private TrueFalse[] mQuestionBank = new TrueFalse[] {
new TrueFalse(R.string.question_oceans, true),
new TrueFalse(R.string.question_mideast, false),
new TrueFalse(R.string.question_africa, false),
new TrueFalse(R.string.question_americas, true),
new TrueFalse(R.string.question_asia, true),
};
private boolean[] mCheatBank = new boolean[mQuestionBank.length];
private int mCurrentIndex = 0;
private boolean mIsCheater;
private void updateQuestion() {
int question = mQuestionBank[mCurrentIndex].getQuestion();
mQuestionTextView.setText(question);
}
private void checkAnswer(boolean userPressedTrue) {
boolean answerIsTrue = mQuestionBank[mCurrentIndex].isTrueQuestion();
int messageResId = 0;
if(mIsCheater) {
messageResId = R.string.judgment_toast;
} else {
if (userPressedTrue == answerIsTrue) {
messageResId = R.string.correct_toast;
} else {
messageResId = R.string.incorrect_toast;
}
}
Toast.makeText(this, messageResId, Toast.LENGTH_SHORT)
.show();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, "onCreate(Bundle) called");
setContentView(R.layout.activity_quiz);
mQuestionTextView = (TextView)findViewById(R.id.question_text_view);
mQuestionTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCurrentIndex = (mCurrentIndex + 1) % mQuestionBank.length;
mIsCheater = false;
updateQuestion();
}
});
mTrueButton = (Button)findViewById(R.id.true_button);
mTrueButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkAnswer(true);
}
});
mFalseButton = (Button) findViewById(R.id.false_button);
mFalseButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
checkAnswer(false);
}
});
mNextButton = (Button)findViewById(R.id.next_button);
mNextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mCurrentIndex = (mCurrentIndex + 1) % mQuestionBank.length;
mIsCheater = mCheatBank[mCurrentIndex];
updateQuestion();
}
});
mCheatButton = (Button)findViewById(R.id.cheat_button);
mCheatButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(QuizActivity.this,CheatActivity.class);
boolean answerIsTrue = mQuestionBank[mCurrentIndex].isTrueQuestion();
i.putExtra(CheatActivity.EXTRA_ANSWER_IS_TRUE, answerIsTrue);
startActivityForResult(i,0);
}
});
if (savedInstanceState != null) {
mCurrentIndex = savedInstanceState.getInt(KEY_INDEX, 0);
mIsCheater = savedInstanceState.getBoolean(CHEATER_BOOLEAN, false);
}
updateQuestion();
} // End of onCreate(Bundle) method
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG,"onActivityResult called");
if (data == null) {
return;
}
mIsCheater = data.getBooleanExtra(CheatActivity.EXTRA_ANSWER_SHOWN, false);
mCheatBank[mCurrentIndex] = mIsCheater;
}
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
Log.d(TAG, "onSaveInstanceState");
savedInstanceState.putInt(KEY_INDEX, mCurrentIndex);
savedInstanceState.putBoolean(CHEATER_BOOLEAN, mIsCheater);
}
Edit 1: Here is the code from the other classes because someone asked.
CheatActivity Code:
public class CheatActivity extends Activity {
public static final String EXTRA_ANSWER_IS_TRUE = "com.bignerrandch.android.geoquiz.answer_is_true";
public static final String EXTRA_ANSWER_SHOWN = "com.bignerdranch.android.geoquiz.answer_shown";
private boolean mAnswerIsTrue;
private boolean mCheater;
private TextView mAnswerTextView;
private Button mShowAnswer;
private void setAnswerShownResult(boolean isAnswerShown) {
Intent data = new Intent();
data.putExtra(EXTRA_ANSWER_SHOWN, isAnswerShown);
setResult(RESULT_OK, data);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cheat);
mAnswerIsTrue = getIntent().getBooleanExtra(EXTRA_ANSWER_IS_TRUE, false);
mAnswerTextView = (TextView)findViewById(R.id.answerTextView);
mCheater = false;
if (savedInstanceState != null) {
mCheater = savedInstanceState.getBoolean(EXTRA_ANSWER_SHOWN, false);
setAnswerShownResult(mCheater);
if (mAnswerIsTrue) {
mAnswerTextView.setText(R.string.true_button);
}
else {
mAnswerTextView.setText(R.string.false_button);
}
} else {
setAnswerShownResult(false);
}
mShowAnswer = (Button)findViewById(R.id.showAnswerButton);
mShowAnswer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mAnswerIsTrue) {
mAnswerTextView.setText(R.string.true_button);
}
else {
mAnswerTextView.setText(R.string.false_button);
}
setAnswerShownResult(true);
mCheater = true;
}
});
}
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
savedInstanceState.putBoolean(EXTRA_ANSWER_SHOWN, mCheater);
}
}
TrueFalse Code:
public class TrueFalse{
private int mQuestion;
private boolean mTrueQuestion;
public TrueFalse(int question, boolean trueQuestion) {
mQuestion = question;
mTrueQuestion = trueQuestion;
}
public int getQuestion() {
return mQuestion;
}
public void setQuestion(int question) {
mQuestion = question;
}
public boolean isTrueQuestion() {
return mTrueQuestion;
}
public void setTrueQuestion(boolean trueQuestion) {
mTrueQuestion = trueQuestion;
}
}
It's not entirely clear what you mean by wiped. But I think your problem is that you are using a member variable to set your array values. So you are setting each element of your array to that value. So essentially the entire array will be set to what ever the final state of mIsCheater is.

I am developing a quiz app. So, in this app user first of all tap on play button and he has to choose category and then he has to choose no of questions and quiz will start.
In quiz activity, problem is that data is not retrieving from firebase firestore in the arraylist. If i did some problem please give the solution.
Below is my code of Main Activity.java where user tap on play button.
package com.example.capitalcamp;
public class MainActivity extends AppCompatActivity {
ActivityMainBinding binding;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
binding.play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MainActivity.this,chooseCategory_Activity.class);
startActivity(intent);
}
});
binding.exit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finish();
}
});
}
}
Now user has to choose category. Below is the code of chooseCategoryActivity.java.
package com.example.capitalcamp;
public class chooseCategory_Activity extends AppCompatActivity {
ArrayList<chooseCategoryModal> chooseCategoryArrayList;
chooseCategoryAdapter chooseCategoryAdapter;
ProgressDialog progressDialog;
FirebaseFirestore db;
CollectionReference ref;
ActivityChooseCategory2Binding binding;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityChooseCategory2Binding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
chooseCategoryArrayList = new ArrayList<>();
progressDialog = new ProgressDialog(this);
progressDialog.setMessage("Loading Categories");
progressDialog.setCancelable(false);
progressDialog.show();
StaggeredGridLayoutManager gridLayoutManager = new StaggeredGridLayoutManager(2,
StaggeredGridLayoutManager.VERTICAL);
binding.categoriesRv.setLayoutManager(gridLayoutManager);
binding.categoriesRv.setHasFixedSize(true);
chooseCategoryAdapter = new chooseCategoryAdapter(chooseCategoryArrayList, chooseCategory_Activity.this);
db = FirebaseFirestore.getInstance();
ref = db.collection("Category");
ref.addSnapshotListener(new EventListener<QuerySnapshot>() {
#Override
public void onEvent(QuerySnapshot value, FirebaseFirestoreException error) {
if (error != null) {
Log.d("ErrorCollection", error.getMessage());
return;
}
chooseCategoryArrayList.clear();
for (DocumentSnapshot snapshot: value.getDocuments()){
chooseCategoryModal modal = snapshot.toObject(chooseCategoryModal.class);
modal.setCategoryId(snapshot.getId());
chooseCategoryArrayList.add(modal);
}
chooseCategoryAdapter.notifyDataSetChanged();
progressDialog.dismiss();
}
});
binding.categoriesRv.setAdapter(chooseCategoryAdapter);
}
}
Below is the code of chooseCategoryModal.java.
package com.example.capitalcamp;
public class chooseCategoryModal {
String categoryName, categoryId;
public chooseCategoryModal() {
}
public chooseCategoryModal(String categoryName, String categoryId) {
this.categoryName = categoryName;
this.categoryId = categoryId;
}
public String getCategoryName() {
return categoryName;
}
public void setCategoryName(String categoryName) {
this.categoryName = categoryName;
}
public String getCategoryId() {
return categoryId;
}
public void setCategoryId(String categoryId) {
this.categoryId = categoryId;
}
}
Below is the code of chooseCategoryAdapter.java.

In this quiz activity, problem is that data is not retrieving from firebase firestore in the arraylist. If i did some problem please give the solution.
i create a true/false quiz app. in that app i have 4 buttons i.e True,False,previous(to get back to previous question),next(to get the next question). i want to add a functionality when a user click on true or false button its get disable for that question so the user can click only once for one question.
i tried to disable the button by using button.setEnabled(false) but when i click on previous button or next button the true/false buttons enabled.i want that the user can click the answer only once it does not matter how much the user traverse the question.
i try to call the setEnabledButton() in previous on click button but it disable the button but it also disable whether the user click on answer or not.

In Questions class you can create a method,
public class Questions {
boolean isQuestionAnswered;
public boolean isQuestionAnswered() {
return isQuestionAnswered;
}
public void setQuestionAnswered(boolean questionAnswered) {
isQuestionAnswered = questionAnswered;
}
}
private void checkAnswer(boolean userPressedTrue)
{
questionbank[mCurrentIndex].setQuestionAnswered(true);
boolean answerIsTrue =
questionbank[mCurrentIndex].ismTrueAnswer();
int messageResId = 0;
if (userPressedTrue == answerIsTrue) {
setButtonEnabled(false);
messageResId = R.string.correct_toast;
} else {
setButtonEnabled(false);
messageResId = R.string.incorrect_toast;
}
Toast.makeText(this, messageResId,
Toast.LENGTH_SHORT)
.show();
}
public void update()
{
int ques = questionbank[mCurrentIndex].getmTextResid();
tquestion.setText(ques);
if(questionbank[mCurrentIndex].isQuestionAnswered())
setButtonEnabled(false);
else
setButtonEnabled(true);
}
Try this out and check whether this solves your problem
New Activity UI load but does not respond, After running onStop() which trigger submit()
List View with the checkbox is bound by a custom adapter. On touch of the Submit button, an intent is triggered which takes me to HomeActivity and onStop() method is triggered which in return call submit method. All submit method is created under a new thread which interfere with UI.

At the moment when running I get only one text displayed Wrong_answer.
public class AnswerActivity extends AppCompatActivity {

TextView textViewDisplayResult = (TextView) findViewById(R.id.text_view_display_result);
textViewDisplayResult.setText(getIntent().getExtras().getString("KEY_ALL_CHECKED"));
textViewDisplayResult.setText(getIntent().getBooleanExtra("KEY_ANSWER", false)?R.string.Good_answer:R.string.Wrong_answer);
}
POST UPDATE
public class MainActivity extends AppCompatActivity {
private static int NUMBER_OF_QUESTIONS = 3;
static boolean[] answer = new boolean[NUMBER_OF_QUESTIONS];
static boolean[] checked = new boolean[NUMBER_OF_QUESTIONS];
static boolean[] isAnswered = new boolean[NUMBER_OF_QUESTIONS];

intent.putExtra("KEY_ALL_CHECKED", R.string.text_not_checked);
else if (checkAnswers())
intent.putExtra("KEY_ANSWER", R.string.Good_answer);
else

startActivity(intent);
}
});
public static void checkSelected() {

break;
}
}
}
private boolean checkAnswers() {
for (boolean radioAnswer : answer) {
if (!radioAnswer) {
return false;
}
}
return true;
}
private boolean allAnswersChecked() {
for (boolean radioAnswer : isAnswered) {
if (!radioAnswer) {
return false;
}
}
return true;
}
and AnswerActivity
public class AnswerActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_answer);
TextView textViewDisplayResult = (TextView) findViewById(R.id.text_view_display_result);
textViewDisplayResult.setText(getIntent().getExtras().getString("KEY_ALL_CHECKED"));
textViewDisplayResult.setText(getIntent().getBooleanExtra("KEY_ANSWER", false)?getString(R.string.Good_answer):getString(R.string.Wrong_answer));
}
}
Second setText will overwrite your first setText value.
....
String x = getIntent().getExtras().getString("KEY_ALL_CHECKED");
textViewDisplayResult.setText(getIntent().getBooleanExtra("KEY_ANSWER", false) ? x +" "+ R.string.Good_answer: x +" "+ R.string.Wrong_answer);
textViewDisplayResult will always overwrite.
If you want both to display in same textView you just need to append the text like below:
textViewDisplayResult.setText(getIntent().getExtras().getString("KEY_ALL_CHECKED"));
textViewDisplayResult.append(getIntent().getBooleanExtra("KEY_ANSWER", false)?getString(R.string.Good_answer):getString(R.string.Wrong_answer));
This will display your both result in same textView.

You can write and apply below mentioned steps (Please ignore any syntactical error, I am giving you simple logical steps).
step 1 - Make a global application level loginObject setter and getter like below. Make sure to define Application class in your manifest just like you do it for your LoginActivity
public class ApplicationClass extends Application{
private LoginBean loginObject;
public void setLoginBean(LoginBean object) {
this.loginObject = object;
}
public LoginBean getName() {
return this.loginObject
}
}
Step - 2 Get an instance of ApplicationClass object reference in LoginActivity to set this global loginObject
e.g. setLogin object in your current Loginactivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
appObject.setLoginBean(loginObject)
}
Step - 3 Get an instance of ApplicationClass object reference in any other Activity get this global loginObject where you need to access this login data.
e.g. getLogin object in your otherActivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
LoginBean loginObject = appObject.getLoginBean();
}
