问题描述
在我的应用程序中，我在同一个类中有倒数计时器和对话框.当有人按下退出按钮对话框打开时，其中有 2 个按钮是和否.我希望当有人按下退出按钮计时器暂停，如果有人按下任何按钮，它会在剩余的秒数内恢复.我知道为此我必须完成这个计时器并用剩余的秒数创建新的计时器.但我无法获得剩余的秒数.如果有人知道如何做到这一点，请帮助我.

倒计时代码-
counterTimer = new CountDownTimer(15000, 1000) {
public void onFinish() {
if(currentGame.getRound()==20)
{
nextBtn1.setEnabled(false);
nextBtn2.setEnabled(false);
nextBtn3.setEnabled(false);
nextBtn4.setEnabled(false);
nextBtn5.setEnabled(false);
final Handler handle = new Handler();
Toast.makeText(QuestionActivity.this, "Time's Up", Toast.LENGTH_SHORT).show();
Runnable delay = new Runnable() {
public void run() {
System.exit(0);
}
};
handle.postDelayed(delay,3000);
}
else if(currentGame.getRound()==0)
{
currentGame.decrementScore();
final Handler handle = new Handler();
Runnable delay = new Runnable() {
public void run() {
processScreen();
}
};
handle.postDelayed(delay,3000);
}
else if(currentGame.getRound()<=19)
{
nextBtn1.setEnabled(false);
nextBtn2.setEnabled(false);
nextBtn3.setEnabled(false);
nextBtn4.setEnabled(false);
nextBtn5.setEnabled(false);
currentGame.decrementScore();
final Handler handle = new Handler();
Toast.makeText(QuestionActivity.this, "Time's Up", Toast.LENGTH_SHORT).show();
Runnable delay = new Runnable() {
public void run() {
processScreen();
}
};
handle.postDelayed(delay,3000);
}
}
public void onTick(long millisUntilFinished) {
TextView time = (TextView) findViewById(R.id.timers);
time.setText( ""+millisUntilFinished/1000);
}
};
counterTimer.start();
}
对话框代码-
if(arg0.getId()==R.id.quit)
{
Button yes, no;
final Dialog dialog = new Dialog(this, R.style.FullHeightDialog);
dialog.setContentView(R.layout.dialog1);
dialog.setCancelable(true);
counterTimer.cancel();
//to set the message
TextView message =(TextView) dialog.findViewById(R.id.tvmessagedialogtext);
message.setText("Are you sure you want to Exit?");
yes = (Button) dialog.findViewById(R.id.bmessageDialogYes);
yes.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
finish();
startActivity(new Intent(QuestionActivity.this, SplashActivity.class));
}
});
no = (Button) dialog.findViewById(R.id.bmessageDialogNo);
no.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
dialog.dismiss();
nextBtn1.setEnabled(true);
nextBtn2.setEnabled(true);
nextBtn3.setEnabled(true);
nextBtn4.setEnabled(true);
}
});
dialog.show();
}

对话框代码-

MyCounter timer;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.question);
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.quit);
nextBtn5.setEnabled(true);
nextBtn5.setOnClickListener(this);
timer = new MyCounter(starttime, 1000);
timer.start();
}
if(arg0.getId() == R.id.quit)
{
timer.cancel();
final Dialog dialog = new Dialog(this, R.style.FullHeightDialog);
