我们在开发中最简单的空间,是日历的实现,而要将他们组合成我们需要的图像,其实操作起来是比较简单的,下面就由爱站技术频道具体介绍Android开发中实现GridLayout自定义的日历控件,一起进入下文参考吧。

我们在开发中最简单的空间,是日历的实现,而要将他们组合成我们需要的图像,其实操作起来是比较简单的,下面就由爱站技术频道具体介绍Android开发中实现GridLayout自定义的日历控件,一起进入下文参考吧。

效果图

思路:就是先设置Gridlayout的行列数,然后往里面放置一定数目的自定义日历按钮控件,最后实现日历逻辑就可以了。

步骤:

第一步:自定义日历控件(初步)

第二步:实现自定义单个日期按钮控件

第三步:将第二步得到的控件动态添加到第一步的布局中,并实现日期逻辑

第四步:编写单个日期点击监听器接口

第一步:自定义日历控件(初步)

package com.包名.myCalendarView;

import java.util.Calendar;
import java.util.Date;

import android.content.Context;
import android.graphics.Color;
import android.util.AttributeSet;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.WindowManager;
import android.widget.GridLayout;
import android.widget.ImageButton;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.xuy849.utils.Info;
import com.xuy849.weightapp.R;

public class MyCalendar extends LinearLayout implements OnClickListener{
 Context context;
 TextView tv_yearAndMonth;
 ImageButton ib_pre;
 ImageButton ib_next;
 ImageButton ib_back;
 GridLayout gl_calendar;
 View view;
 CalendarButton buttons[];
 int sideLength;
 String week[] = {"日","一","二","三","四","五","六"};
 Date date;
 Calendar calendar;
 int year,month,day;
 int res;
 
 public MyCalendar(Context context, AttributeSet attrs, int defStyle) {
 super(context, attrs, defStyle);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }

 public MyCalendar(Context context, AttributeSet attrs) {
 super(context, attrs);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }

 public MyCalendar(Context context) {
 super(context);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }
 
 private void init(){
 this.view = LayoutInflater.from(context).inflate(R.layout.my_calendar_view, this);
 
 
 }
}

效果图:(请无视ListView)

第二步:自定义单个日期按钮控件

 

 

package com.包名.myCalendarView;

import java.util.Date;

import android.content.Context;
import android.graphics.Color;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.xuy849.utils.Info;
import com.xuy849.weightapp.R;


class CalendarButton extends LinearLayout{

 Context context;
 TextView tv_date;
 TextView tv_data;
 ImageView iv_note;
 LinearLayout ll_container;
 View view;
 Date date;
 
 public CalendarButton(Context context, AttributeSet attrs, int defStyle) {
 super(context, attrs, defStyle);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }

 public CalendarButton(Context context, AttributeSet attrs) {
 super(context, attrs);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }
 
 public void setTotalEnable(boolean b){
 this.setEnabled(b);
 }

 public CalendarButton(Context context) {
 super(context);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 
 }
 
 public void setDate(Date date){
 this.date = date;
 }

 public Date getDate(){
 return this.date;
 }
 
 private void init(){
 view = LayoutInflater.from(context).inflate(R.layout.date_button, this);
 
 //findViewById
 tv_date =(TextView)view.findViewById(R.id.textView1);
 tv_data = (TextView)view.findViewById(R.id.textView2);
 iv_note = (ImageView)view.findViewById(R.id.imageView1);
 ll_container = (LinearLayout)view.findViewById(R.id.linearLayout01);
 
 }
 
 public void setDateText(String text){
 tv_date.setText(text);
 }
 
 public void setDateTextColor(int color){
 tv_date.setTextColor(color);
 }
 }
 
}

效果图:

第三步:将第二步得到的控件在java代码中添加到第一步的布局中,并添加相关逻辑

 

package com.包名.myCalendarView;

import java.util.Calendar;
import java.util.Date;

import android.content.Context;
import android.graphics.Color;
import android.util.AttributeSet;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.WindowManager;
import android.widget.GridLayout;
import android.widget.ImageButton;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.xuy849.utils.Info;
import com.xuy849.weightapp.R;

public class MyCalendar extends LinearLayout implements OnClickListener{
 Context context;
 TextView tv_yearAndMonth;
 ImageButton ib_pre;
 ImageButton ib_next;
 ImageButton ib_back;
 GridLayout gl_calendar;
 View view;
 CalendarButton buttons[];
 int sideLength;
 String week[] = {"日","一","二","三","四","五","六"};
 Date date;
 Calendar calendar;
 int year,month,day;
 int res;
 
 public MyCalendar(Context context, AttributeSet attrs, int defStyle) {
 super(context, attrs, defStyle);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }

 public MyCalendar(Context context, AttributeSet attrs) {
 super(context, attrs);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }

 public MyCalendar(Context context) {
 super(context);
 
 this.context = context;
 // TODO Auto-generated constructor stub
 
 init();
 }
 
 private void init(){
 this.view = LayoutInflater.from(context).inflate(R.layout.my_calendar_view, this);
 
 WindowManager ww = (WindowManager)getContext().getSystemService(Context.WINDOW_SERVICE);
 sideLength = ww.getDefaultDisplay().getWidth()/Info.COLUMN_COUNT;
 
 //
 myFindViewById();
 
 //初始化日历按钮布局
 initCalendarLayout();
 
 //初始化按钮点击事件
 initButton();
 
 }
 
 private void initButton(){
 ib_pre.setOnClickListener(this);
 ib_next.setOnClickListener(this);
 ib_back.setOnClickListener(this);
 }
 
 private void myFindViewById(){
 tv_yearAndMonth = (TextView)view.findViewById(R.id.textView1);
 ib_pre = (ImageButton)view.findViewById(R.id.imageButton2);
 ib_next = (ImageButton)view.findViewById(R.id.imageButton3);
 ib_back = (ImageButton)view.findViewById(R.id.imageButton1);
 gl_calendar =(GridLayout)view.findViewById(R.id.gridLayout01);
 
 //
 buttons = new CalendarButton[Info.COLUMN_COUNT*Info.ROW_COUNT];
 
 }
 
  //根据传递过来的calendar,绘制当月的日历视图
  private void initCalendar(Calendar calendar){
 int year = calendar.get(Calendar.YEAR);
 int month = (calendar.get(Calendar.MONTH)+1);
 int date = calendar.get(Calendar.DATE);
 
 //设置标题
 String todayStr = String.format("%04d年%02d月", calendar.get(Calendar.YEAR),(calendar.get(Calendar.MONTH)+1));
 tv_yearAndMonth.setText(todayStr);
 
 //
 calendar.set(Calendar.DAY_OF_MONTH, 1);
 int currentMonthFirstDateInWeek = calendar.get(Calendar.DAY_OF_WEEK)-1;
 calendar.set(Calendar.DAY_OF_MONTH, date);
 int currentMonthDaysSum = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
 
 calendar.roll(Calendar.MONTH, -1);
 int lastMonthDaysSum = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
 int i;
 calendar.roll(Calendar.MONTH, 1);
 
 Log.w("月", currentMonthDaysSum+"天");
 Log.w("上月", lastMonthDaysSum +"天");
 
 /*
  * 设置日期
  */
 //设置本月
 Log.w("currentMonthFirstDateInWeek",currentMonthFirstDateInWeek+"");
 Log.w("currentMonthFirstDateInWeek%7111",currentMonthDaysSum+currentMonthFirstDateInWeek%7+"");
 
 for(i=currentMonthFirstDateInWeek%7+7;i

第四步:编写单个日期点击监听器接口

在第三步中添加方法:

//设置下标是index的日期按钮的点击事件监听器
public void setOnClickButtonListener(OnClickListener l,int index){ 
 buttons[index].setOnClickListener(l);
 }
