Android使用GridLayout繪制自定義日歷控件

編輯：關於Android編程

效果圖

思路：就是先設置Gridlayout的行列數，然後往裡面放置一定數目的自定義日歷按鈕控件，最後實現日歷邏輯就可以了。

步驟：

第一步：自定義日歷控件（初步）

第二步：實現自定義單個日期按鈕控件

第三步：將第二步得到的控件動態添加到第一步的布局中，並實現日期邏輯

第四步：編寫單個日期點擊監聽器接口

第一步：自定義日歷控件（初步）

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

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);
 
 
 }
}

效果圖：（請無視ListView）

第二步：自定義單個日期按鈕控件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@drawable/background01"
  android:orientation="vertical" >

  <LinearLayout
    android:layout_width="wrap_content"
    android:id="@+id/linearLayout01"
    android:layout_height="wrap_content"
    android:background="@color/calendarBackground"
    android:orientation="vertical" 
    android:layout_marginBottom="1dp">

    <FrameLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent" >

      <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="invisible"
        android:src="@drawable/selected_date" />

      <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" 
        android:gravity="center">

        <TextView
          android:id="@+id/textView1"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:textSize="8pt"
          android:text="20" />

        <TextView
          android:id="@+id/textView2"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_marginTop="3dp"
          android:textColor="@color/blue"
          android:visibility="invisible"
          android:text="65.1" />

      </LinearLayout>

    </FrameLayout>

  </LinearLayout>

</LinearLayout>



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);
 }
 }
 
}

效果圖：

第三步：將第二步得到的控件在java代碼中添加到第一步的布局中，並添加相關邏輯

package com.包名.myCalendarView;

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

import android.content.Context;

 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

 }
 
 private void init(){

 WindowManager ww = (WindowManager)getContext().getSystemService(Context.WINDOW_SERVICE);
 sideLength = ww.getDefaultDisplay().getWidth()/Info.COLUMN_COUNT;
 
 //
 myFindViewById();
 
 //初始化日歷按鈕布局
 initCalendarLayout();
 
 //初始化按鈕點擊事件
 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];
 
 }
 
  //根據傳遞過來的calendar，繪制當月的日歷視圖
  private void initCalendar(Calendar calendar){
 int year = calendar.get(Calendar.YEAR);
 int month = (calendar.get(Calendar.MONTH)+1);
 int date = calendar.get(Calendar.DATE);
 
 //設置標題
 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");
 
 /*
  * 設置日期
  */
 //設置本月
 Log.w("currentMonthFirstDateInWeek",currentMonthFirstDateInWeek+"");

 for(i=currentMonthFirstDateInWeek%7+7;i<=(currentMonthDaysSum+currentMonthFirstDateInWeek%7+7-1)&&i<Info.COLUMN_COUNT*Info.ROW_COUNT;i++){
  buttons[i].changeToState(Info.STATE_NORMAL_NORECORED);
  buttons[i].setDateText((i-currentMonthFirstDateInWeek%7-7+1)+"");
  buttons[i].setDateTextColor(Color.BLACK);

  buttons[i].setDate(new Date(year,month,i-(currentMonthFirstDateInWeek%7+7)+1));
 }
 
 //設置上一個月
 for(i=7;i<(currentMonthFirstDateInWeek%7+7)&&i<Info.COLUMN_COUNT*Info.ROW_COUNT;i++){
  buttons[i].changeToState(Info.STATE_NORMAL_NORECORED);
  buttons[i].setDateTextColor(Color.GRAY);
  buttons[i].setDateText(lastMonthDaysSum-(currentMonthFirstDateInWeek%7-i%7)+1+"");
  buttons[i].setEnabled(false);
 }
 
 //設置下一個月
 for(i =currentMonthDaysSum+currentMonthFirstDateInWeek%7+7;i<Info.ROW_COUNT*Info.COLUMN_COUNT;i++){

 //初始化界面
 if(res!=0)
  initLayout(res);
 
 }
 
 
 private void initCalendarLayout(){
 //設置行數，列數
 gl_calendar.setRowCount(Info.ROW_COUNT);
 gl_calendar.setColumnCount(Info.COLUMN_COUNT);
 
 
 /*
  * 添加按鈕到布局
  */
 int i;
 int sum = Info.ROW_COUNT*Info.COLUMN_COUNT;
 
 //設置星期
 for(i=0;i<Info.COLUMN_COUNT;i++){
  buttons[i] = new CalendarButton(context);
  buttons[i].setDateText(week[i]);
  buttons[i].setLayoutParams(new LayoutParams(sideLength, sideLength));
  gl_calendar.addView(buttons[i], i);
  buttons[i].setEnabled(false);
 }
 
 for(i = Info.COLUMN_COUNT;i<sum;i++){
  buttons[i] = new CalendarButton(context);
  buttons[i].setDateText("55");
  buttons[i].setLayoutParams(new LayoutParams(sideLength, sideLength));
  gl_calendar.addView(buttons[i], i);
 }
 
 
 //根據當月設置情況
 calendar = Calendar.getInstance();
 year = calendar.get(Calendar.YEAR);
 month = calendar.get(Calendar.MONTH)+1;
 day = calendar.get(Calendar.DATE);
 initCalendar(calendar);
 
 
 }

 @Override
 public void onClick(View v) {
 // TODO Auto-generated method stub
 switch(v.getId()){
 
 //上一個月
 case R.id.imageButton2:{
  calendar.roll(Calendar.MONTH, -1);
  initCalendar(calendar);
  break;
 }
 
 //下一個月
 case R.id.imageButton3:{
  calendar.roll(Calendar.MONTH, 1);
  initCalendar(calendar);
  break;
 }
 }
 }
 
 public void setOnClickButtonListener(OnClickListener l,int index){ 
 buttons[index].setOnClickListener(l);
 }
 
 public Date getDate(int index){
 return buttons[index].getDate();
 }
 
 public void setData(float f,int index){
 buttons[index].tv_data.setText(String.format("%.1f", f));
 buttons[index].tv_data.setVisibility(TextView.VISIBLE);
 }
 
 public void initLayout(int res){
 switch(res){
 case Info.VIEW_WEIHT:{
  
  
  break;
 }
 
 default:{
  break;
 }
 }
 }
 
 public void setRes(int res){
 this.res = res;
 }
}

第四步：編寫單個日期點擊監聽器接口

在第三步中添加方法：

//設置下標是index的日期按鈕的點擊事件監聽器
public void setOnClickButtonListener(OnClickListener l,int index){ 
 buttons[index].setOnClickListener(l);
 }
