我想获得当前时间安装了应用程序在Android设备上。

I would like to get the current time on the android device with the app installed.

我希望能够做这样的事。

if(//time is pass noon){

//Do something

else{
//do something.
}

推荐答案

下面是一个例子，应该可以帮助您：

Here is an example that should help you:

Calendar today = Calendar.getInstance();
Calendar expireDate = Calendar.getInstance();

expireDate.set(2011, Calendar.AUGUST, 12);

if (today.compareTo(expireDate) == 0 || today.compareTo(expireDate) == 1)

{
// expired - please purchase app

}
else
{
// do some stuff
}

要判断它是上午还是下午使用：

To tell if it is AM or PM use:

int value = today.get(Calendar.AM_PM);

或者你可以只得到一小时：

Or you could just get the hour:

int hour = today.get(Calendar.HOUR);

然后把在if语句：

And then put that in an if statement:

if (hour > 12)
{

// do stuff

}
else
{
// do other stuff
}
