android控件开发之TimerPicker和DatePicker

java代码：

package com.example.timepicker;

import android.os.Bundle;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TimePicker;

public class MainActivity extends Activity {

private final int TIMER = 1;
private final int DATE = 2;

private Button showTimerButton = null;
private Button showDateButton = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

showTimerButton = (Button)findViewById(R.id.showTimePicker);

showTimerButton.setOnClickListener(new showTimerDialogListener());

showDateButton = (Button)findViewById(R.id.showDatePicker);

showDateButton.setOnClickListener(new showDateDialogListener());

}

//Date button的监听器
class showDateDialogListener implements OnClickListener{

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//显示Date Diaolog
showDialog(DATE);
}

}

//Timer button 监听器
class showTimerDialogListener implements OnClickListener{

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

//显示ID为TIMER的dialog
showDialog(TIMER);

//TimePickerDialog timerDialog = new TimePickerDialog(this, onTimeSetListener, 22, 54, true);
//timerDialog.show();
}

}

//此方法由showDialog()调用并且传入Dialog ID
protected Dialog onCreateDialog(int id){
Dialog dialog = null;
switch(id){
//当ID为TIMER时，创建一个TimePickerDialog对象并且返回
case TIMER:
dialog = new TimePickerDialog(this, onTimeSetListener, 22, 54, true);
break;
//当ID为DATE时，创建一个DatePickerDialog对象并且返回
case DATE:
dialog = new DatePickerDialog(this, onDateSetListener, 2014, 12, 10);
break;
}
return dialog;
}

main.xml文件如下：

Strings.xml代码如下：

<?xml version="1.0" encoding="utf-8"?>
<resources>

<string name="app_name">PickerDialog</string>
<string name="action_settings">Settings</string>
<string name="hello_world">Hello world!</string>
<string name="show_timer">Show Time Dialog</string>
<string name="show_date">Show Date Dialog</string>
</resources>
