Android使用GridLayout绘制自定义日历控件

作者：FlyinTang

这篇文章主要为大家详细介绍了Android使用GridLayout绘制自定义日历控件的相关资料,具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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

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

        android:src="@drawable/selected_date" />

      <LinearLayout

        <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>

 init();
 }

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

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

 public Date getDate(){
 return this.date;
 }
 
 private void init(){

 //findViewById
 tv_date =(TextView)view.findViewById(R.id.textView1);
 tv_data = (TextView)view.findViewById(R.id.textView2);

 }
 
 public void setDateText(String text){
 tv_date.setText(text);
 }
 
 public void setDateTextColor(int color){
 tv_date.setTextColor(color);
 }
 }
 
}

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

 //初始化按钮点击事件
 initButton();
 
 }
 
 private void initButton(){

  //根据传递过来的calendar，绘制当月的日历视图

 int year = calendar.get(Calendar.YEAR);
 int month = (calendar.get(Calendar.MONTH)+1);
 int date = calendar.get(Calendar.DATE);
 
 //设置标题

 tv_yearAndMonth.setText(todayStr);
 
 //
 calendar.set(Calendar.DAY_OF_MONTH, 1);
 int currentMonthFirstDateInWeek = calendar.get(Calendar.DAY_OF_WEEK)-1;

 }
 
 
 private void initCalendarLayout(){
 //设置行数，列数
 gl_calendar.setRowCount(Info.ROW_COUNT);
 gl_calendar.setColumnCount(Info.COLUMN_COUNT);
 
 
 /*
  * 添加按钮到布局
  */
 int i;
 int sum = Info.ROW_COUNT*Info.COLUMN_COUNT;
 
 //设置星期
 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);
 }
 
 
 //根据当月设置情况
 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()){
 
 //上一个月
 case R.id.imageButton2:{
  calendar.roll(Calendar.MONTH, -1);
  initCalendar(calendar);
  break;
 }
 
 //下一个月
 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：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);
 }
