AnalogClock和DigitalClock时间和日期控件

 

   AnalogClock和DigitalClock（显示时钟的控件）.

一、建立工程，如图

二、activity_main.xml中代码

<?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">
    
    <AnalogClock 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
                
        />
    <DigitalClock 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="18dp"
        />
    
    <Button 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/button1"
        android:text="显示TimePickerDialog"
        />
    <Button 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/button2"
        android:text="显示DatePickerDialog"
        />
      
    
</LinearLayout>

三、MainActivity.java中代码

package com.study.analogcolck;

import java.util.Calendar;

import android.os.Bundle;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.DatePickerDialog.OnDateSetListener;
import android.app.TimePickerDialog;
import android.app.TimePickerDialog.OnTimeSetListener;
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;
import android.widget.Toast;

public class MainActivity extends Activity implements OnClickListener {

    private Button button1,button2;
    private int hourOfDay,minute;
    private int year,monthOfYear,dayOfMonth;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        button1 = (Button)this.findViewById(R.id.button1);
        button2 = (Button)this.findViewById(R.id.button2);
        button1.setOnClickListener(this);
        button2.setOnClickListener(this);
        
        //获得当前的时间，获得小时和分钟
        Calendar calendar = Calendar.getInstance();
        hourOfDay = calendar.get(Calendar.HOUR_OF_DAY);
        minute = calendar.get(Calendar.MINUTE); 
        year = calendar.get(Calendar.YEAR);
        monthOfYear = calendar.get(Calendar.MONTH);
        dayOfMonth = calendar.get(calendar.DAY_OF_MONTH);
    }


    @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;
    }


    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.button1:
            TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this, new MyTimePickerDialog(), hourOfDay, minute, true);
            timePickerDialog.show();
            break;
        case R.id.button2:
            DatePickerDialog datePickerDialog = new DatePickerDialog(MainActivity.this, new MyDatePickerDialog(), year, monthOfYear, dayOfMonth);
            datePickerDialog.show();
            break;
        default:
            break;
        }
        
    }
    
    public class MyTimePickerDialog implements OnTimeSetListener{

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            Toast.makeText(MainActivity.this, "H:" + hourOfDay +"   minute:" + minute, 1).show();
    
        }
        
    }
    public class MyDatePickerDialog implements OnDateSetListener{

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            Toast.makeText(MainActivity.this, year+"年" + monthOfYear+" 月" +dayOfMonth+ "  日", 1).show();
            
        }
        
    }
    
}
