android日历控件(一)

自定义日历并且具备设置今天以前的时间不可点选，以前的颜色和当前的颜色不同，以及获取两次点击日期之间间隔的天数所以说细节比较多

个人习惯，先上图

靠，笔记本不知道怎么回事，禁用到触摸板之后再次唤醒屏幕触摸板又恢复正常了，而且快捷键可能被占用还是怎么着，找不到关闭快捷键的图标，关闭的话需要重启才行，懒得管了蛋疼，瘪犊子玩意！

项目中用到日历控件，需求大致是这样：

有两处用到日历控件：一个是显示每个月份全部的天数，实现滑动跳到下一月份，以前月份的天数不可点选，点击今天及以后的天数的时候刷新页面显示日期，获取两次点击的间隔数以及相关的计算(android这方面用原生的话肯定不行，而且后台和ios商量用ios风格，android仿ios这方面的轮子就更少了，没办法，遇到不会的就查呗，查不到就问呗，问不到的只能"靠"了);

第二个需求是显示每周的天数实现多选，这个很简单。

重点来了：：：》》》

所以说要完全自定义日历并且具备设置以前或者以后时间不可点选，以前的颜色和当前的颜色不同，以及获取两次点击日期之间间隔的天数所以说细节比较多，，，

Calendar大家都清楚,获取时间：

不断刷新秒，简单的时钟就出来了，

package com.example.mydemo;

import java.util.Calendar;

import android.os.Bundle;
import android.os.Handler;

public class MainActivity extends Activity implements OnClickListener{

/**

private int mHour;
private int mMinute;
private int mYear;
private int mMonth;
private int mDay;
private TextView text;
private int second;
private int ampm;
private Handler mHandler=new Handler(){};
@Override
protected void onCreate(Bundle savedInstanceState) {
　　super.onCreate(savedInstanceState);
　　setContentView(R.layout.activity_main);

　　text = (TextView) findViewById(R.id.text);
　　button = (Button) findViewById(R.id.button);
　　button.setOnClickListener(this);

　　init();

　　mHandler.postDelayed(new Runnable() {
　　　　@Override
　　　　public void run() {
　　　　// TODO Auto-generated method stub
　　　　mHandler.postDelayed(this, 1000);
　　　　init();
　　　　text.setText("年："+mYear+",月："+mMonth+",日："+mDay+","+mHour+":"+mMinute+":秒"+second);
　　　　}
　　}, 1000);
}
　　private void init(){
　　　　Calendar c = Calendar.getInstance();
　　　　mYear = c.get(Calendar.YEAR); //获取当前年份
　　　　mMonth = c.get(Calendar.MONTH)+1;//获取当前月份
　　　　mDay = c.get(Calendar.DAY_OF_MONTH);//获取当前月份的日期号码
　　　　mHour = c.get(Calendar.HOUR_OF_DAY);//获取当前的小时数
　　　　mMinute = c.get(Calendar.MINUTE);//获取当前的分钟数
　　　　second = c.get(Calendar.SECOND);//获取当前的秒数
　　　　ampm = c.get(Calendar.AM_PM); //0-上午；1-下午
　　　　//当前年的第几周这个需求感觉没什么用
　　　　int week_of_year = c.get(Calendar.WEEK_OF_YEAR);
　　　　//当前月的第几周
　　　　int week_of_month = c.get(Calendar.WEEK_OF_MONTH);
　　　　//当前年的第几天
　　　　int day_of_year = c.get(Calendar.DAY_OF_YEAR);

　　　　mHandler.sendEmptyMessage(0);
　　}

/**
* 点击出现日历弹框
*/
　　private PickDialog dialog;
　　private Button button;
　　private void getData(){
　　dialog = new PickDialog(this);
　　dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
　　dialog.show();
　　}
　　@Override
　　public void onClick(View v) {
　　　　// TODO Auto-generated method stub
　　　　switch (v.getId()) {
　　　　case R.id.button:
