DataPicker(输入日期控件),DatePicker控件可用于输入日期,日期的范围是1900-1-1到2100-12-31.

<?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"> <DatePicker android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/datepicker" /> <TimePicker android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/timepicker" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/textview" android:textSize="18dp" /> </LinearLayout>

package com.study.datetimepicker; import java.text.SimpleDateFormat; import java.util.Calendar; import android.os.Bundle; import android.app.Activity; import android.view.Menu; import android.widget.DatePicker; import android.widget.DatePicker.OnDateChangedListener; import android.widget.TextView; import android.widget.TimePicker; import android.widget.Toast; import android.widget.TimePicker.OnTimeChangedListener; public class MainActivity extends Activity implements OnDateChangedListener,OnTimeChangedListener{ private TextView textView; private DatePicker datePicker; private TimePicker timePicker; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); datePicker = (DatePicker)this.findViewById(R.id.datepicker); timePicker = (TimePicker)this.findViewById(R.id.timepicker); textView = (TextView)this.findViewById(R.id.textview); datePicker.init(2001, 1, 25, this);//初始化日期 timePicker.setIs24HourView(true);//显示时间是否是按24小时制 timePicker.setOnTimeChangedListener(this);//注册事件 } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } //日期控件的触发 @Override public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) { Calendar calendar = Calendar.getInstance(); calendar.set(datePicker.getYear(), datePicker.getMonth(), datePicker.getDayOfMonth(), timePicker.getCurrentHour(), timePicker.getCurrentMinute()); SimpleDateFormat format = new SimpleDateFormat("yyyy年MM月dd日 HH:mm"); textView.setText(format.format(calendar.getTime())); } //时间空间的触发 @Override public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { Toast.makeText(MainActivity.this, "hourOfDay:" + hourOfDay + " minute:" + minute, 1).show(); } }
