利用Android应用框架提供的DatePicker（日期选择器）和TimePicker（时间选择器），实现日期时间选择器。
Dialog的Content布局文件（date_time_dialog.xml）：
<?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" android:padding="10dip" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:singleLine="true" android:text="请选择日期" android:textColor="#FFFFFF" android:textSize="16sp" /> <DatePicker android:id="@+id/date_picker" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="5dip" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="10dip" android:singleLine="true" android:text="请选择时间" android:textColor="#FFFFFF" android:textSize="16sp" /> <TimePicker android:id="@+id/time_picker" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="5dip" /></LinearLayout>
代码中的实现：
package com.easipass.test;import java.util.Calendar;import android.app.Activity;import android.app.AlertDialog;import android.app.Dialog;import android.content.DialogInterface;import android.os.Bundle;import android.text.InputType;import android.view.MotionEvent;import android.view.View;import android.widget.DatePicker;import android.widget.EditText;import android.widget.TimePicker;/** * 功能描述：实现日期时间选择器 * * @author android_ls */public class DateTimeActivity extends Activity implements View.OnTouchListener { private EditText etStartTime; private EditText etEndTime; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); etStartTime = (EditText) this.findViewById(R.id.et_start_time); etEndTime = (EditText) this.findViewById(R.id.et_end_time); etStartTime.setOnTouchListener(this); etEndTime.setOnTouchListener(this); } @Override public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN) { AlertDialog.Builder builder = new AlertDialog.Builder(this); View view = View.inflate(this, R.layout.date_time_dialog, null); final DatePicker datePicker = (DatePicker) view.findViewById(R.id.date_picker); final TimePicker timePicker = (android.widget.TimePicker) view.findViewById(R.id.time_picker); builder.setView(view); Calendar cal = Calendar.getInstance(); cal.setTimeInMillis(System.currentTimeMillis()); datePicker.init(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH), null); timePicker.setIs24HourView(true); timePicker.setCurrentHour(cal.get(Calendar.HOUR_OF_DAY)); timePicker.setCurrentMinute(Calendar.MINUTE); if (v.getId() == R.id.et_start_time) { final int inType = etStartTime.getInputType(); etStartTime.setInputType(InputType.TYPE_NULL); etStartTime.onTouchEvent(event); etStartTime.setInputType(inType); etStartTime.setSelection(etStartTime.getText().length()); builder.setTitle("选取起始时间"); builder.setPositiveButton("确 定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { StringBuffer sb = new StringBuffer(); sb.append(String.format("%d-%02d-%02d", datePicker.getYear(), datePicker.getMonth() + 1, datePicker.getDayOfMonth())); sb.append(" "); sb.append(timePicker.getCurrentHour()) .append(":").append(timePicker.getCurrentMinute()); etStartTime.setText(sb); etEndTime.requestFocus(); dialog.cancel(); } }); } else if (v.getId() == R.id.et_end_time) { int inType = etEndTime.getInputType(); etEndTime.setInputType(InputType.TYPE_NULL); etEndTime.onTouchEvent(event); etEndTime.setInputType(inType); etEndTime.setSelection(etEndTime.getText().length()); builder.setTitle("选取结束时间"); builder.setPositiveButton("确 定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { StringBuffer sb = new StringBuffer(); sb.append(String.format("%d-%02d-%02d", datePicker.getYear(), datePicker.getMonth() + 1, datePicker.getDayOfMonth())); sb.append(" "); sb.append(timePicker.getCurrentHour()) .append(":").append(timePicker.getCurrentMinute()); etEndTime.setText(sb); dialog.cancel(); } }); } Dialog dialog = builder.create(); dialog.show(); } return true; } } 运行后的效果图：
