DatePicker實例代碼：

前端界面：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><DatePickerandroid:layout_height="wrap_content"android:layout_width="wrap_content"android:id="@+id/datePicker"/> </LinearLayout>

業務邏輯：

package com.example.tf.datepicker;import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.DatePicker;import java.util.Calendar;public class MainActivity extends AppCompatActivity {private DatePicker datePicker;private int year,month,day;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);this.datePicker = (DatePicker) this.findViewById(R.id.datePicker);Calendar calendar = Calendar.getInstance();year = calendar.get(Calendar.YEAR);month = calendar.get(Calendar.MONTH) + 1;day = calendar.get(Calendar.DATE);this.datePicker.init(year, month, day, new DatePicker.OnDateChangedListener() {@Overridepublic void onDateChanged(DatePicker datePicker, int year, int monthOfYear, int dayOfMonth) {String strDate = year + "-" + monthOfYear + "-" + dayOfMonth;System.out.println("strDate" + strDate);//銷毀當前activity，相當于按下返回鍵finish();}});System.out.println(year+"-"+month+"-"+day);} }

TimePicker實例代碼：

實例代碼：

前端展示：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><TimePickerandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/timePiacker"/> </LinearLayout>

后臺邏輯：

package com.example.lenovo.timepicker;import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.TimePicker;import java.sql.Time; import java.util.Calendar;public class MainActivity extends AppCompatActivity {private TimePicker timePicker;private int hour;private int minute;private int seconds;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);this.timePicker = (TimePicker) this.findViewById(R.id.timePiacker);//是否使用24小時制,默認是12小時制this.timePicker.setIs24HourView(true);//得到日歷控件Calendar calendar = Calendar.getInstance();hour=calendar.get(Calendar.HOUR);minute=calendar.get(Calendar.MINUTE);seconds=calendar.get(Calendar.SECOND);String strTime = hour+":"+minute+":"+seconds;System.out.println("strTime:"+strTime);//使用匿名內部類來實現this.timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener(){@Overridepublic void onTimeChanged(TimePicker timePicker, int hourOfDay, int minute) {String strTime = hourOfDay + ":" +minute;System.out.println("strTime="+strTime);}});} }
