DatePickerDialog对话框和TimePickerDialog对话框比单独的DatePicker组件和TimePicker组件更好用,用法也比较简单,下面通过一个简单实例来演示它们的使用:
Activity:
package com.lovo; import java.util.Calendar; import android.app.Activity; import android.app.DatePickerDialog; import android.app.TimePickerDialog; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.DatePicker; import android.widget.TextView; import android.widget.TimePicker; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // 获得设置日期按钮 Button dateBtn = (Button) findViewById(R.id.btn1); // 获得设置时间按钮 Button timeBtn = (Button) findViewById(R.id.btn2); // 为设置日期按钮绑定监听器 dateBtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { Calendar c = Calendar.getInstance(); // 直接创建一个DatePickerDialog对话框实例,并将它显示出来 new DatePickerDialog(MainActivity.this, // 绑定监听器 new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { TextView show = (TextView) findViewById(R.id.txt1); show.setText("您选择了:" + year + "年" + monthOfYear + "月" + dayOfMonth + "日"); } } // 设置初始日期 , c.get(Calendar.YEAR), c.get(Calendar.MONTH), c .get(Calendar.DAY_OF_MONTH)).show(); } }); // 为设置时间按钮绑定监听器 timeBtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Calendar c = Calendar.getInstance(); // 创建一个TimePickerDialog实例,并把它显示出来 new TimePickerDialog(MainActivity.this, // 绑定监听器 new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { TextView show = (TextView) findViewById(R.id.txt2); show.setText("您选择了:" + hourOfDay + "时" + minute + "分"); } } // 设置初始时间 , c.get(Calendar.HOUR_OF_DAY), c.get(Calendar.MINUTE), // true表示采用24小时制 true).show(); } }); } }
布局XML:
<?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" android:gravity="center" android:orientation="vertical" > <Button android:id="@+id/btn1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="设置日期" /> <Button android:id="@+id/btn2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="设置时间" /> <TextView android:id="@+id/txt1" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/txt2" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>

点击按钮弹出下面对话框,可以选择日期或时间:
