我正在使用android studio开发一个测验应用程序来玩测验，当我单击按钮中的答案时，它将暂停游戏并显示一个描述问题的完整描述并具有按钮名称恢复的布局。点击简历后，它将返回并继续游戏并显示下一个问题
这是Playing.class的代码 这是我在viewGame方法上的代码
private void viewGame(View view) {
if (pause_flg == false) {
pause_flg = true;
mCountDown.cancel();
mCountDown = null;
frameview.setVisibility(View.VISIBLE);
}else{
pause_flg = false;
resume.setBackgroundColor(Color.GREEN);
frameview.setVisibility(View.GONE);
mCountDown = new CountDownTimer(mTimeLeftInMillis, 1000) {
@Override
public void onTick(long millisUntilFinished) {
mTimeLeftInMillis = millisUntilFinished;
int minutes = (int) (mTimeLeftInMillis / 1000) / 60;
int seconds = (int) (mTimeLeftInMillis / 1000) % 60;
String timeLeftFormatted = String.format(Locale.getDefault(), "%02d:%02d", minutes, seconds);
txtTimer.setText(timeLeftFormatted);
}
@Override
public void onFinish() {
//when time stop it will go to the next question
Intent myIntent = new Intent(Playing.this,Done.class);
showQuestion(index);
finish();
}
};
showQuestion(index);
}
}
这是我在OnClick Answers方法上的代码
public void onClick(View view) {
if (index < totalQuestion) //still have question in list
{
btnA.setOnClickListener((View v) -> {
if(btnA.getText().toString().equals(Common.questionList.get(index).getCorrectAnswer()))

btnA.setEnabled(false);
btnB.setEnabled(false);

handler.postDelayed(() -> {

score += 1;
correctAnswer++;
showQuestion(++index);
btnA.setEnabled(true);
btnB.setEnabled(true);
btnC.setEnabled(true);
btnD.setEnabled(true);
txtScore.setText(String.format("%d", score));

}
}
});
//choose correct Answer
// next question
}
else {
if (index < totalQuestion) //still have question in list
{
showQuestion(++index); // next question
}else{
//Choose Wrong Answer
Intent intent = new Intent(this, Done.class);
Bundle dataSend = new Bundle();
dataSend.putInt("SCORE", score);
dataSend.putInt("TOTAL", totalQuestion);
dataSend.putInt("CORRECT", correctAnswer);
intent.putExtras(dataSend);
startActivity(intent);
finish();
}
}
txtScore.setText(String.format("%d", score));
}
这是我在showQuestion方法中的代码
private void showQuestion(final int index) {
if (index < totalQuestion) {
thisQuestion++;
txtQuestionNum.setText(String.format("%d / %d", thisQuestion, totalQuestion));
progressBar.setProgress(100);
progressValue = 0;
question_text.setText(Common.questionList.get(index).getQuestion());
//if question is text we will set image to invisible
btnA.setText(Common.questionList.get(index).getAnswerA());
btnB.setText(Common.questionList.get(index).getAnswerB());
btnC.setText(Common.questionList.get(index).getAnswerC());
btnD.setText(Common.questionList.get(index).getAnswerD());
mCountDown.start();
}
else
{
// if it is final question
Intent intent = new Intent(Playing.this, Done.class);
Bundle dataSend = new Bundle();
dataSend.putInt("SCORE", score);
dataSend.putInt("TOTAL", totalQuestion);
dataSend.putInt("CORRECT", correctAnswer);
intent.putExtras(dataSend);
startActivity(intent);
finish();
}
}
This is my onResume method or countdowntimer
protected void onResume(int seconds, final TextView tv) {
super.onResume();
totalQuestion = Common.questionList.size();
mCountDown = new CountDownTimer(mTimeLeftInMillis, 1000) {
@Override
public void onTick(long millisUntilFinished) {
mTimeLeftInMillis = millisUntilFinished;
updateCountDownText();
}
@Override
public void onFinish() {
//when time stop it will go to the next question
showQuestion(++index);
Intent myIntent = new Intent(Playing.this,Done.class);
tv.setText("Completed");
}
};
showQuestion(index);
}
