Android DatePicker和TimePicker案例

簡介 下面以一個讓使用者選擇日期、時間的例子來示範DatePicker和TimePicker的功能和用法step1:建立一個項目DateAndTimePicker step2:編寫應用的UI介面  /layout/main.xml[html] <?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:orientation="vertical" android:layout_width="fill_parent"      android:layout_height="fill_parent">      <TextView android:layout_width="fill_parent"          android:layout_height="wrap_content" android:text="選擇購買此書的具體時間" />            <DatePicker android:id="@+id/datePicker"          android:layout_width="wrap_content" android:layout_height="wrap_content"          android:layout_gravity="center_horizontal"/>            <TimePicker android:id="@+id/timePicker"          android:layout_width="wrap_content" android:layout_height="wrap_content"          android:layout_gravity="center_horizontal"/>            <EditText android:layout_width="fill_parent"          android:layout_height="wrap_content" android:editable="false"          android:cursorVisible="false"          android:id="@+id/show" />  </LinearLayout>    step3:主程式MainActivity.java[java]  package cn.roco.picker;    import java.util.Calendar;    import android.app.Activity;  import android.os.Bundle;  import android.widget.DatePicker;  import android.widget.DatePicker.OnDateChangedListener;  import android.widget.EditText;  import android.widget.TimePicker;  import android.widget.TimePicker.OnTimeChangedListener;    public class MainActivity extends Activity {        private int year;      private int month;      private int day;      private int hour;      private int minute;        /** Called when the activity is first created. */      @Override      public void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.main);            DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker);          TimePicker timePicker = (TimePicker) findViewById(R.id.timePicker);            Calendar calendar = Calendar.getInstance();          year = calendar.get(Calendar.YEAR);          month = calendar.get(Calendar.MONTH);          day = calendar.get(Calendar.DAY_OF_MONTH);          hour = calendar.get(Calendar.HOUR);          minute = calendar.get(Calendar.MINUTE);            datePicker.init(year, month, day, new OnDateChangedListener() {              @Override              public void onDateChanged(DatePicker view, int year, int month,                      int day) {                  MainActivity.this.year = year;                  MainActivity.this.month = month;                  MainActivity.this.day = day;                  // 顯示時間                  showDate(year, month, day, hour, minute);              }          });            timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {              @Override              public void onTimeChanged(TimePicker view, int hour, int minute) {                  MainActivity.this.hour = hour;                  MainActivity.this.minute = minute;                  // 顯示時間                  showDate(year, month, day, hour, minute);              }          });      }        private void showDate(int year, int month, int day, int hour, int minute) {          EditText show = (EditText) findViewById(R.id.show);          show.setText("您的購買日期為:" + year + "年" + month + "月" + day + "日 " + hour                  + "時" + minute + "分 ");      }    }    step4:部署應用到模擬器上，並選擇日期和時間
