Android中实现日期时间选择器(DatePicker和TimePicker)

时间:2022-05-02 18:09:09

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):

<span style="font-size:18px;"><?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>
</span>

代码中的实现:

<span style="font-size:18px;">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;

/**

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;
}

}
</span>
