Android实现淘宝倒计时功能

本文实例为大家分享了android实现淘宝倒计时的具体代码，供大家参考，具体内容如下

一、效果图（这里为了方便我就没弄gif图了，功能是能动的）

二、实现步骤

1.自定义倒计时控件、

package com.cqxxny.myapplication;
 
import android.annotation.suppresslint;
import android.content.context;
import android.os.handler;
import android.os.message;
import android.util.attributeset;
import android.view.layoutinflater;
import android.view.view;
import android.widget.linearlayout;
import android.widget.textview;
import android.widget.toast;
 
import java.util.timer;
import java.util.timertask;
/**
 * 功 能: 倒计时工具类
 * 所属模块:
 * 创建时间: 2018/11/15
 * 功能描述:
 */
@suppresslint("handlerleak")
public class rushbuycountdowntimerview extends linearlayout {
 
 // 小时，十位
 private textview tv_hour_decade;
 // 小时，个位
 private textview tv_hour_unit;
 // 分钟，十位
 private textview tv_min_decade;
 // 分钟，个位
 private textview tv_min_unit;
 // 秒，十位
 private textview tv_sec_decade;
 // 秒，个位
 private textview tv_sec_unit;
 
 private context context;
 
 private int hour_decade;
 private int hour_unit;
 private int min_decade;
 private int min_unit;
 private int sec_decade;
 private int sec_unit;
 // 计时器
 private timer timer;
 
 private handler handler = new handler() {
 
 public void handlemessage(message msg) {
 countdown();
 };
 };
 
 public rushbuycountdowntimerview(context context, attributeset attrs) {
 super(context, attrs);
 
 this.context = context;
 layoutinflater inflater = (layoutinflater) context
 .getsystemservice(context.layout_inflater_service);
 view view = inflater.inflate(r.layout.time, this);
 
 tv_hour_decade = (textview) view.findviewbyid(r.id.tv_hour_decade);
 tv_hour_unit = (textview) view.findviewbyid(r.id.tv_hour_unit);
 tv_min_decade = (textview) view.findviewbyid(r.id.tv_min_decade);
 tv_min_unit = (textview) view.findviewbyid(r.id.tv_min_unit);
 tv_sec_decade = (textview) view.findviewbyid(r.id.tv_sec_decade);
 tv_sec_unit = (textview) view.findviewbyid(r.id.tv_sec_unit);
 
 }
 
 /**
 *
 * @description: 开始计时
 * @param
 * @return void
 * @throws
 */
 public void start() {
 
 if (timer == null) {
 timer = new timer();
 timer.schedule(new timertask() {
 
 @override
 public void run() {
  handler.sendemptymessage(0);
 }
 }, 0, 1000);
 }
 }
 
 /**
 *
 * @description: 停止计时
 * @param
 * @return void
 * @throws
 */
 public void stop() {
 if (timer != null) {
 timer.cancel();
 timer = null;
 }
 }
 
 /**
 * @throws exception
 *
 * @description: 设置倒计时的时长
 * @param
 * @return void
 * @throws
 */
 public void settime(int hour, int min, int sec) {
 
 if (hour >= 60 || min >= 60 || sec >= 60 || hour < 0 || min < 0
 || sec < 0) {
 throw new runtimeexception("time format is error,please check out your code");
 }
 
 hour_decade = hour / 10;
 hour_unit = hour - hour_decade * 10;
 
 min_decade = min / 10;
 min_unit = min - min_decade * 10;
 
 sec_decade = sec / 10;
 sec_unit = sec - sec_decade * 10;
 
 tv_hour_decade.settext(hour_decade + "");
 tv_hour_unit.settext(hour_unit + "");
 tv_min_decade.settext(min_decade + "");
 tv_min_unit.settext(min_unit + "");
 tv_sec_decade.settext(sec_decade + "");
 tv_sec_unit.settext(sec_unit + "");
 
 }
 
 /**
 *
 * @description: 倒计时
 * @param
 * @return boolean
 * @throws
 */
 private void countdown() {
 
 if (iscarry4unit(tv_sec_unit)) {
 if (iscarry4decade(tv_sec_decade)) {
 
 if (iscarry4unit(tv_min_unit)) {
  if (iscarry4decade(tv_min_decade)) {
 
  if (iscarry4unit(tv_hour_unit)) {
  if (iscarry4decade(tv_hour_decade)) {
  toast.maketext(context, "时间到了",
   toast.length_short).show();
  stop();
  }
  }
  }
 }
 }
 }
 }
 
 /**
 *
 * @description: 变化十位，并判断是否需要进位
 * @param
 * @return boolean
 * @throws
 */
 private boolean iscarry4decade(textview tv) {
 
 int time = integer.valueof(tv.gettext().tostring());
 time = time - 1;
 if (time < 0) {
 time = 5;
 tv.settext(time + "");
 return true;
 } else {
 tv.settext(time + "");
 return false;
 }
 
 }
 
 /**
 *
 * @description: 变化个位，并判断是否需要进位
 * @param
 * @return boolean
 * @throws
 */
 private boolean iscarry4unit(textview tv) {
 
 int time = integer.valueof(tv.gettext().tostring());
 time = time - 1;
 if (time < 0) {
 time = 9;
 tv.settext(time + "");
 return true;
 } else {
 tv.settext(time + "");
 return false;
 }
 
 }
}

2.自定义控件xml、

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:gravity="center"
 android:orientation="horizontal">
 
 <textview
  android:id="@+id/tv_hour_decade"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@drawable/sousuo"
  android:gravity="center"
  android:padding="5dp"
  android:text="0"
  android:textcolor="#ffffff"
  android:textsize="20dp" />
 
 <textview
  android:id="@+id/tv_hour_unit"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_marginleft="2dp"
  android:background="@drawable/sousuo"
  android:gravity="center"
  android:padding="5dp"
  android:text="0"
  android:textcolor="#ffffff"
  android:textsize="20dp" />
 
 <textview
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:gravity="center"
  android:text=":"
  android:padding="5dp"
  android:textcolor="#454545"
  android:textsize="20dp" />
 
 <textview
  android:id="@+id/tv_min_decade"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@drawable/sousuo"
  android:gravity="center"
  android:text="0"
  android:padding="5dp"
  android:textcolor="#ffffff"
  android:textsize="20dp"/>
 
 <textview
  android:id="@+id/tv_min_unit"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_marginleft="1dp"
  android:background="@drawable/sousuo"
  android:gravity="center"
  android:padding="5dp"
  android:text="0"
  android:textcolor="#ffffff"
  android:textsize="20dp"/>
 
 <textview
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:gravity="center"
  android:text=":"
  android:padding="5dp"
  android:textcolor="#454545"
  android:textsize="20dp" />
 
 
 <textview
  android:id="@+id/tv_sec_decade"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@drawable/sousuo"
  android:gravity="center"
  android:text="0"
  android:padding="5dp"
  android:textcolor="#ffffff"
  android:textsize="20dp"/>
 
 <textview
  android:id="@+id/tv_sec_unit"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_marginleft="1dp"
  android:background="@drawable/sousuo"
  android:gravity="center"
  android:padding="5dp"
  android:text="0"
  android:textcolor="#ffffff"
  android:textsize="20dp" />
 
</linearlayout>

3.自定义控件转圆角、

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
 
 <!-- 背景颜色 -->
 <solid android:color="#454545" />
 
 
 <!-- 控制边界线颜色和大小 -->
 <stroke
  android:width="1dp"
  android:color="#454545" />
 
 <!-- 控制圆角大小 -->
 <corners android:radius="5dp" />
 
</shape>

4.activity代码

package com.cqxxny.myapplication;
 
import android.support.v7.app.appcompatactivity;
import android.os.bundle;
 
public class mainactivity extends appcompatactivity {
 /**
  * 功 能: 倒计时
  * 所属模块:
  * 创建时间: 2018/11/15
  * 功能描述:
  */
 private rushbuycountdowntimerview timerview;
 @override
 protected void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_main);
  timerview = (rushbuycountdowntimerview) findviewbyid(r.id.timerview);
  // 设置时间(hour,min,sec)
  timerview.settime(10, 0, 10);
  // 开始倒计时
  timerview.start();
 }
}

5.activity的xml布局

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:gravity="center"
 tools:context=".mainactivity">
 
 <com.cqxxny.myapplication.rushbuycountdowntimerview
  android:id="@+id/timerview"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"></com.cqxxny.myapplication.rushbuycountdowntimerview>
 
</linearlayout>
