We Keep Coding

I don't understand this error message, any help would be helpful

I tried to build my app, and this error message was produced.
Unexpected character '=' (code 61) (expected a name start character)
at [row,col {unknown-source}]: [41,21]
I have cleaned my code and tried to clean my code and inspected my code and i can't find anything wrong my code, and help would be gratefully recieved.
This is my MainActivity.

looping through an array backwards from current position

I am quite new to java and android so be patient with me. I have an xml layout containing two buttons. One containing text of "previous" and the other "next". I also have a class containing array of strings which loops in an ascending order in a textView when a "next" button is clicked.
What i want is that i want the array to loop backwards from its current position when the "previous" button is clicked. Any ideas?
Question Class
// This file contains questions from QuestionBank
class Question{
// array of questions
private String mQuestions [] = {
"",
"",
"",
"",
"",
"",
"",
"",
"",
"",
"",
"",
// method returns number of questions
int getLength(){
return mQuestions.length;
}
// method returns question from array textQuestions[] based on array index
String getQuestion(int a) {
return mQuestions[a];
}
}
Main Activity.java
public class MainActivityextends AppCompatActivity {
private QuestionLibraryBeginner mQuestionLibrary = new QuestionLibraryBeginner();
private int mQuestionNumber = 1; // current question number
//initialising navigation buttons
private Button mPrevious;
private Button mNext;
private TextView mQuestionText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_beginner_review);
mPrevious = (Button) findViewById(R.id.previous);
mNext = (Button) findViewById(R.id.next);
mQuestionText = (TextView) findViewById(R.id.txtQuestion);
// receive the current question number from last activity by Intent
Intent intent = getIntent();
currentQuestionNumber = intent.getIntExtra("quizNumber", 0); // receiving the number of questions the user has attempted from previous activity
mNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// checking against total number of questions the user has attempted instead of total number of questions from Question Class
if (mQuestionNumber < currentQuestionNumber) {
updateQuestion();
}
});
mPrevious.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// i want it to loop backwards from here
}
});
// logic to update question from array
private void updateQuestion() {
if (mQuestionNumber < mQuestionLibrary.getLength()) {
mQuestionText.setText(mQuestionLibrary.getQuestion(mQuestionNumber));
mQuestionNumber++;
}
}
}

I would suggest to do this:
1) Rename updateQuestion method to nextQuestion
2) Create a method to decrease the mQuestionNumber like this:
private void prevQuestion(){
if(mQuestionNumber > 0){
mQuestionText.setText(mQuestionLibrary.getQuestion(mQuestionNumber));
mQuestionNumber--;}
}

Here's a solution accounting for bounds
mNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
showNextQuestion();
}
});
mPrevious.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
showPreviousQuestion();
}
});
private void showNextQuestion() {
showQuestion(1);
}
private void showPreviousQuestion() {
showQuestion(-1);
}
private void showQuestion(int increment) {
int newQuestionNumber = mQuestionNumber + increment;
if (newQuestionNumber >= 0 && newQuestionNumber < mQuestionLibrary.getLength()) {
mQuestionNumber = newQuestionNumber;
mQuestionText.setText(mQuestionLibrary.getQuestion(mQuestionNumber));
}
}

It can be done by just adding a flag to mention the move,
mNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
updateQuestion(true);
});
mPrevious.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
updateQuestion(false);
}
});
And the method would look like:
private void updateQuestion(boolean forward) {
if(forward && mQuestionNumber < mQuestionLibrary.getLength())
mQuestionNumber++
else if (mQuestionNumber>1)
mQuestionNumber--;
mQuestionText.setText(mQuestionLibrary.getQuestion(mQuestionNumber));
}

I would change the following methodes:
would remove mQuestionNummer++; from update question.
You can increment mQuestions directly in the onClickMethode of NextButton.
So you can implement your solution simply by decrement mQuestion-- in onClick of previous Button.
Code would look like this:
public class MainActivityextends AppCompatActivity {
private QuestionLibraryBeginner mQuestionLibrary = new
QuestionLibraryBeginner();
private int mQuestionNumber = 1; // current question number
//initialising navigation buttons
private Button mPrevious;
private Button mNext;
private TextView mQuestionText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_beginner_review);
mPrevious = (Button) findViewById(R.id.previous);
mNext = (Button) findViewById(R.id.next);
// receive the current question number from last activity by Intent
Intent intent = getIntent();
mNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mQuestionNumber < mQuestionLibrary.getLength()) {
mQuestionNumber++;
updateQuestion();
}
});
mPrevious.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// i want it to loop backwards from here
if(mQuestionNumber > 0){
mQuestionNumber--;
updateQuestion();
}
else
{}//don't do anything to prevent IndexOutOfBounds
}
});
// logic to update question from array
private void updateQuestion() {
if (mQuestionNumber < mQuestionLibrary.getLength()) {
mQuestionText.setText(mQuestionLibrary.getQuestion(mQuestionNumber));
}
}
}

You need to don't mess logic of your application with view logic, decouple them.
Just make class Question able to provide previous and next questions. Also according to oop principles (solid, grasp) fetch information from class and make decision outside is wrong, make class to do it's work. Oop it's about telling classes to do things, not work instead of them.
class Questions {
private int index = 0;
private String[] mQuestions;
//better to don't hardcode and provide questions in constructor
public Question(String[] questions) {
this.questions = questions;
}
//we don't need this method
int getLength(){
return mQuestions.length;
}
//provide human readable information about current position in question list
// when you want to provide this information to user introduce label field in activity
public String currentPosition() {
int questionPosition = index + 1;
int questionsLength = mQuestions.length;
return String.format("current question number is %d from %d" , questionPosition, questionsLength);
}
//return next question when available, if next not available returns last question from array
public String next() {
int lastIndex = mQuestions.length - 1;
if(index < lastIndex) {
index++;
}
return mQuestions[index];
}
//return current question
public String current() {
return mQuestions[index];
}
//return previous question when available, if previous not available returns first question from array
public String previous() {
int firstIndex = 0;
if(index > firstIndex) {
index--;
}
return mQuestions[index];
}
}
And how to use it in Activity:
public class MainActivity extends AppCompatActivity {
//better to don't hardcode here, but provide this class from
//constructor of MainActivity just like questions array provide
// to constructor in Questions class
private Questions questions = new Questions(new String[]{"q1","q2"});
private Button mPrevious;
private Button mNext;
private TextView mQuestionText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_beginner_review);
mPrevious = (Button) findViewById(R.id.previous);
mNext = (Button) findViewById(R.id.next);
Intent intent = getIntent();
//when create Activity populate question field with first question
mQuestionText.setText(questions.current());
mNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mQuestionText.setText(questions.next());
}
});
mPrevious.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mQuestionText.setText(questions.previous());
}
});
}
}
p.s. you may improve this code further in way to introduce Observer pattern, Activity is a view, Questions is model.

Send a value from Mainactivity and display the value in another activity

I am trying to make a simple quiz app and I want to display the score value in another activity(another screen) i.e. when I press the submit button the score activity should open and display the total score.
I have tried using intents but it hasn't worked. I am new at android programming and there could be some silly mistakes.
This is the MainActivity.java file.
package com.example.android.conanquiz;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.RadioButton;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
int score = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
//Question 1 Methods
public void question1_click(View view) {
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch (view.getId()) {
case R.id.haibara:
if (checked) {
String correct = "Right Answer";
display_answer1(correct);
score++;
}
break;
default: {
String wrong = "Wrong Answer" + "\n" + "The right answer is " + getString(R.string.q1_o1);
display_answer1(wrong);
}
break;
}
}
private void display_answer1(String answer) {
TextView quantityTextView = (TextView) findViewById(R.id.answer_1);
quantityTextView.setText(answer);
}
//Question 2 Methods
public void question2_click(View view) {
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch (view.getId()) {
case R.id.true_op:
if (checked) {
String correct = "Right Answer";
display_answer2(correct);
score++;
}
break;
default: {
String wrong = "Wrong Answer" + "\n" + "The right answer is " + getString(R.string.q2_o1);
display_answer2(wrong);
}
break;
}
}
private void display_answer2(String answer) {
TextView quantityTextView = (TextView) findViewById(R.id.answer_2);
quantityTextView.setText(answer);
}
//Question 3 Methods
public void question3_click(View view) {
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch (view.getId()) {
case R.id.q3_op3:
if (checked) {
String correct = "Right Answer";
display_answer3(correct);
score++;
}
break;
default: {
String wrong = "Wrong Answer" + "\n" + "The right answer is " + getString(R.string.q3_o3);
display_answer3(wrong);
}
break;
}
}
private void display_answer3(String answer) {
TextView quantityTextView = (TextView) findViewById(R.id.answer_3);
quantityTextView.setText(answer);
}
//Question 4 Methods
public void question4_click(View view) {
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch (view.getId()) {
case R.id.q4_op1:
if (checked) {
String correct = "Right Answer";
display_answer4(correct);
score++;
}
break;
default: {
String wrong = "Wrong Answer" + "\n" + "The right answer is " + getString(R.string.q4_o1);
display_answer4(wrong);
}
break;
}
}
private void display_answer4(String answer) {
TextView quantityTextView = (TextView) findViewById(R.id.answer_4);
quantityTextView.setText(answer);
}
//Question 5 Methods
public void question5_click(View view) {
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch (view.getId()) {
case R.id.q5_op3:
if (checked) {
String correct = "Right Answer";
display_answer5(correct);
score++;
}
break;
default: {
String wrong = "Wrong Answer" + "\n" + "The right answer is " + getString(R.string.q5_o3);
display_answer5(wrong);
}
break;
}
}
private void display_answer5(String answer) {
TextView quantityTextView = (TextView) findViewById(R.id.answer_5);
quantityTextView.setText(answer);
}
//Submit Button
public void onClickSubmit(View view){
Intent scoreActivity = new Intent(MainActivity.this,Score.class);
scoreActivity.putExtra("sendScore", score);
startActivity(scoreActivity);
}
}
This is the other activity java(Score.java) file
package com.example.android.conanquiz;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
public class Score extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_score);
Intent scoreActivity = getIntent();
int totalScore = scoreActivity.getIntExtra("sendScore", 0);
displayScore(totalScore);
}
public void displayScore(int score) {
TextView scoreTextView = (TextView) findViewById(R.id.score);
scoreTextView.setText(score);
}
}

Try to print score on button click using log. if score is not null than write below code.
From Activity
Intent intent = new Intent(getBaseContext(), Score.class);
intent.putExtra("EXTRA_SCORE", score);
startActivity(intent);
To Activity
Intent intent = getIntent();
int intValue = intent.getIntExtra("EXTRA_SCORE", 0);

equals method doesn't work when comparing TextView String

So I'm new to java and I'm trying to make quiz app as exercise. I kinda made one but it doesn't work:
public class QuizActivity extends AppCompatActivity {
TextView QuestionText;
Button button1;
Button button2;
Button button3;
Button button4;
ArrayList<Question> listOfQuestions;
int currentQuestion = 0;
Context context = this;
int NumberOfQuestions;
GameCreator game;
String totalCorrect = "";
String totalWrong = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_quiz);
QuestionText = (TextView) findViewById(R.id.textJautajums);
button1 = (Button) findViewById(R.id.buttonOpcija1);
button2 = (Button) findViewById(R.id.buttonOpcija2);
button3 = (Button) findViewById(R.id.buttonOpcija3);
button4 = (Button) findViewById(R.id.buttonOpcija4);
NumberOfQuestions = Integer.parseInt(context.getString(R.string.JautajumuSkaits).toString());
game = new GameCreator(NumberOfQuestions);
listOfQuestions = game.makeQuestions();
Resources r = getResources();
int px1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 165, r.getDisplayMetrics());
button1.setWidth(px1);
button2.setWidth(px1);
button3.setWidth(px1);
button4.setWidth(px1);
Resources e = getResources();
int px2 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 125, r.getDisplayMetrics());
button1.setHeight(px2);
button2.setHeight(px2);
button3.setHeight(px2);
button4.setHeight(px2);
if (currentQuestion == 0){
setQuestion(listOfQuestions.get(0));
}
button1.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View V){
gajiens(button1.getText().toString(), listOfQuestions.get(currentQuestion));
currentQuestion++;
}
}
);
button2.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View V){
gajiens(button2.getText().toString(), listOfQuestions.get(currentQuestion));
currentQuestion++;
}
}
);
button3.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View V){
gajiens(button3.getText().toString(), listOfQuestions.get(currentQuestion));
currentQuestion++;
}
}
);
button4.setOnClickListener(
new Button.OnClickListener(){
public void onClick(View V){
gajiens(button4.getText().toString(), listOfQuestions.get(currentQuestion));
currentQuestion++;
}
}
);
}
public void gajiens(String answer, Question thisQuestion){
if (currentQuestion < 14){
if (answer.equals(thisQuestion.getAnswer())){
totalCorrect += "Question: " + thisQuestion.getQuestion() + "\nYour Answer: " + answer + "\n";
} else {
totalWrong += "Question: " + thisQuestion.getQuestion()) + "\nYour Answer: " + answer + "\n";
}
currentQuestion++;
setQuestion(listOfQuestions.get(currentQuestion));
} else {
Intent intent = new Intent(this, EndActivity.class);
intent.putExtra("correct", totalCorrect);
intent.putExtra("wrong", totalWrong);
startActivity(intent);
}
}
public void setQuestion(Question kursh){
QuestionText.setText(kursh.getJautajums());
button1.setText(kursh.getOption1());
button2.setText(kursh.getOption2());
button3.setText(kursh.getOption3());
button4.setText(kursh.getOption4());
}
object Question is:
public Question(String Question, String Option1, String Option2, String Option3,String Option4, String correctAnswer){
Question = Question;
Option1 = Option1;
Option2 = Option2;
Option3 = Option3;
Option4 = Option4;
correctAnswer = correctAnswer;
}
Basically the problem is that App doesn't count the right answers. For some reason it most of the time uses the original text of TextView as ''correctAnswer''. Anyone has any idea what to do? I suspect since this isn't working properly this isn't particularly best approach so maybe someone can suggest a better one?

to compare the value of a TextView with a String you can do this as below
TextView tvAnswer = (TextView) findViewById(R.id.tvAnswer);
String correctAnswer = "Correct Answer";
if(correctAnswer.equals(tvAnswer.getText.toString()) )
{
//do something
}
else{
//do something
}

How to start Timer when Activity Loaded?

I am working on Timer. I have created a TextView in my Question XML(Where I have to Implement Timer to display) and PlayButton in Welcome XML (Timer in Question Activity Start When Play button Is Clicked) .I have WelcomeActivity where I have implemented PlayButton and QuestionActivity Where I wanted to Function my timer.I am attaching My Code Here:-
Welcome XML:-
<Button
android:text="Play"
android:id="#+id/playBtn"
android:layout_width="80dip"

I am trying To add A function in QuestionActivity But I don't know how to proceed to call my timer One activity to another Activity. so that my timer display on Question XMl after Clicking the Play Button In Welcome XMl.Can anyone help me How to add listener in another activity Or some other way to solve My Problem.
thank's in Advance

why would you start the timer when the button is clicked?
you can set the button to go to the next activity and start the timer on that activity when
it is called...
(sorry this is what i understand with your question: you want the timer to start when the button is clicked and the timer is on another activity?)
