Iam已經完成了IQ測試app.Iam使用定時器來計算完成IQTest中的問題所需的時間。當我暫停定時器時，我會去Timeplease活動。這是正確的，但是當我回到測試時，計時器不會恢復。也有人可以告訴如何計算所需的時間來回答正確的問題。當我回到QuizActivity時，定時器不會恢復
這是AgeCalculation.java
package com.example.iqtest;
public class AgeCalculation extends Activity implements OnTouchListener
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_age_calculation);

calage = (Button) findViewById(R.id.btnCalculateAge);
go = (Button) findViewById(R.id.button1);
category=(EditText) findViewById(R.id.category);
final Calendar c = Calendar.getInstance();
Year = c.get(Calendar.YEAR);
Month = c.get(Calendar.MONTH);
Day = c.get(Calendar.DAY_OF_MONTH);
mDate.setOnTouchListener(this);
calage.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v){
Calendar now= Calendar.getInstance();
Calendar calendar = Calendar.getInstance();
calendar.set(Year, Month, Day);
int years = now.get(Calendar.YEAR) - calendar.get(Calendar.YEAR);
int months = now.get(Calendar.MONTH) - calendar.get(Calendar.MONTH);
int days = now.get(Calendar.DAY_OF_MONTH) - calendar.get(Calendar.DAY_OF_MONTH);
if (days < 0){
months --;
days +=now.getActualMaximum(Calendar.DAY_OF_MONTH);
}
if (months < 0){
years --;
months +=12;
}
String yearsold = years+" YEARS "+months+ " MONTHS "+days+" DAYS"+" "+"OLD";
age.setText(yearsold);
if(years>=0 && years<=10)
{
opt=0;
}else if(years>=11 && years<=15)
{
opt=1;

}else
{

}
switch (opt) {
case 0:

@Override

這是QuizActivity.java
package com.example.iqtest;
public class QuizActivity extends Activity {

}
這是Timeplease.java
package com.example.iqtest;
public class Timeplease extends Activity {
Button back;
