I have Implemented a countdowntimer in my application.it's working fine.Now i implemented a quit button in my app with dialog box permission (yes or no).when user press yes then quit and no back to game.Now my problem is how to pause the Countdowntimer when i click on quit button and resume on no button in dialog box.
Here is my code:-
public class QuestionActivity extends Activity implements OnClickListener{
private Question currentQ;
private GamePlay currentGame;
public CountDownTimer counterTimer;
private Button nextBtn1, nextBtn2, nextBtn3, nextBtn4, nextBtn5;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.question);
processScreen();
}
/**
* Configure current game and get question
*/
private void processScreen()
{
currentGame = ((Application)getApplication()).getCurrentGame();
currentQ = currentGame.getNextQuestion();
nextBtn1 = (Button) findViewById(R.id.answer1);
nextBtn1.setEnabled(true);
nextBtn1.setOnClickListener(this);
nextBtn2 = (Button) findViewById(R.id.answer2);
nextBtn2.setEnabled(true);
nextBtn2.setOnClickListener(this);
nextBtn3 = (Button) findViewById(R.id.answer3);
nextBtn3.setEnabled(true);
nextBtn3.setOnClickListener(this);
nextBtn4 = (Button) findViewById(R.id.answer4);
nextBtn4.setEnabled(true);
nextBtn4.setOnClickListener(this);
nextBtn5 = (Button) findViewById(R.id.answer5);
nextBtn5.setEnabled(true);
nextBtn5.setOnClickListener(this);
/**
* Update the question and answer options..
*/
setQuestions();
}
/**
* Method to set the text for the question and answers from the current games
* current question
*/
private void setQuestions() {
//set the question text from current question
String question = Utility.capitalise(currentQ.getQuestion());
TextView qText = (TextView) findViewById(R.id.question);
qText.setText(question);
//set the available options
List<String> answers = currentQ.getQuestionOptions();
TextView option1 = (TextView) findViewById(R.id.answer1);
option1.setText(Utility.capitalise(answers.get(0)));
TextView option2 = (TextView) findViewById(R.id.answer2);
option2.setText(Utility.capitalise(answers.get(1)));
TextView option3 = (TextView) findViewById(R.id.answer3);
option3.setText(Utility.capitalise(answers.get(2)));
TextView option4 = (TextView) findViewById(R.id.answer4);
option4.setText(Utility.capitalise(answers.get(3)));
int score = currentGame.getScore();
String scr = String.valueOf(score);

score1.setText(scr);
