这将给出当前的日期和时间:

public String getCurrDate()
{
    String dt;
    Date cal = Calendar.getInstance().getTime();
    dt = cal.toLocaleString();
    return dt;
}

使用实例显示当前日期函数。

Calendar c = Calendar.getInstance();

SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String date = df.format(c.getTime());
Date.setText(date);

您一定想导入

进口java.text.SimpleDateFormat; 进口java.util.Calendar;

你一定想用

TextView Date;
Date = (TextView) findViewById(R.id.Date);

显示时间的明显选择是类比时钟视图(AnalogClock View)和数字时钟视图(DigitalClock View)。

例如，如下布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:orientation="vertical">

    <AnalogClock
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"/>

    <DigitalClock 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:gravity="center" 
        android:textSize="20sp"/>
</LinearLayout>

看起来是这样的:

我自己的工作解决方案:

Calendar c = Calendar.getInstance();

String sDate = c.get(Calendar.YEAR) + "-" 
+ c.get(Calendar.MONTH)
+ "-" + c.get(Calendar.DAY_OF_MONTH) 
+ " at " + c.get(Calendar.HOUR_OF_DAY) 
+ ":" + c.get(Calendar.MINUTE);

希望这能有所帮助!

试试下面的代码:

SimpleDateFormat dateFormat = new SimpleDateFormat(
                                    "yyyy/MM/dd HH:mm:ss");

Calendar cal = Calendar.getInstance();
System.out.println("time => " + dateFormat.format(cal.getTime()));

String time_str = dateFormat.format(cal.getTime());

String[] s = time_str.split(" ");

for (int i = 0; i < s.length; i++) {
     System.out.println("date  => " + s[i]);
}

int year_sys = Integer.parseInt(s[0].split("/")[0]);
int month_sys = Integer.parseInt(s[0].split("/")[1]);
int day_sys = Integer.parseInt(s[0].split("/")[2]);

int hour_sys = Integer.parseInt(s[1].split(":")[0]);
int min_sys = Integer.parseInt(s[1].split(":")[1]);

System.out.println("year_sys  => " + year_sys);
System.out.println("month_sys  => " + month_sys);
System.out.println("day_sys  => " + day_sys);

System.out.println("hour_sys  => " + hour_sys);
System.out.println("min_sys  => " + min_sys);

public class XYZ extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);

        Calendar c = Calendar.getInstance();
        System.out.println("Current time => "+c.getTime());

        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String formattedDate = df.format(c.getTime());
        // formattedDate have current date/time
        Toast.makeText(this, formattedDate, Toast.LENGTH_SHORT).show();


      // Now we display formattedDate value in TextView
        TextView txtView = new TextView(this);
        txtView.setText("Current Date and Time : "+formattedDate);
        txtView.setGravity(Gravity.CENTER);
        txtView.setTextSize(20);
        setContentView(txtView);
    }
