SwipeCaptcha_ohos

本项目是基于开源项目SwipeCaptcha进行鸿蒙化的移植和开发的,可以通过项目标签以及github地址(https://github.com/mcxtzhang/SwipeCaptcha)追踪到原安卓项目版本。

项目介绍
  • 项目名称:滑动验证码
  • 所属系列:鸿蒙的第三方组件适配移植
  • 功能:实现了滑动验证的功能,可以判断验证成功或失败
  • 项目移植状态:100%,已完成全部的功能移植
  • 调用差异:重构
  • 开发版本:DevEco Studio 3.0 Beta1, SDK 5.0
  • 项目发起作者:赵柏屹
  • 邮箱:isrc_hm@iscas.ac.cn
  • 原项目Doc地址:https://github.com/mcxtzhang/SwipeCaptcha

项目介绍
  • 编程语言:Java
  • 本项目为封装的第三方库,使用时需要将库导入项目。SwipeCaptchaView类继承了DependentLayout,使用时需在xml文件中以添加控件的方式添加至界面中。
  • 拓展了一部份功能,添加了RotateCaptchaView类,用于实现旋转类型的滑动验证码。
使用教程
  1. 在xml文件中添加SwipeCaptchaView(或RotateCaptchaView)

    <!-- ability_main.xml -->
    <!--在这里添加 xmlns:app,为后面传入控件参数提供命名空间-->
    <DirectionalLayout
    	xmlns:app="http://schemas.huawei.com/res/ohos-auto">
        
    	<!--拼图验证码的参数可以从xml中设置,包括拼图的 宽 高 验证的阈值-->
        <!--这些参数也可以从 java 文件中动态设置-->
        <com.huawei.swipecaptchaview.lib.SwipeCaptchaView
            ohos:id="$+id:swipeCaptchaView"
            ohos:height="220vp"
            ohos:width="330vp"
            app:captchaHeight="30vp"
            app:captchaWidth="30vp"
            app:matchDeviation="9"/>
        
        <!--旋转验证码的参数也可从xml中设置,包括旋转块的 半径 验证的阈值-->
        <!--这些参数也可以从 java 文件中动态设置-->
        <com.huawei.swipecaptchaview.lib.RotateCaptchaView
            ohos:id="$+id:rotateCaptchaView"
            ohos:height="220vp"
            ohos:width="match_parent"
            ohos:left_margin="10vp"
            ohos:right_margin="10vp"
            app:captchaRadius="80vp"
            app:matchDeviation="8"/>
    </DirectionalLayout>

    注意:这里如果宽度定为match_parent,如再需要定义前后边距,必须使用 left_margin / right_margin,否则会不起作用。

  2. AbilitySlice.java 文件中绑定控件

    • SwipeCaptchaView
    //MainAbilitySlice.java
    public class MainAbilitySlice extends AbilitySlice {
        SwipeCaptchaView swipeCaptchaView;
        
        @Override
        public void onStart(Intent intent) {
            super.onStart(intent);
            super.setUIContent(ResourceTable.Layout_ability_main);
            
            //根据 id 找到相应的控件
            swipeCaptchaView = (SwipeCaptchaView) findComponentById(ResourceTable.Id_swipeCaptchaView);
            //调用 setImageId 方法设置图片,如不设置图片,则会显示一张“暂无图片”内容的图片
            swipeCaptchaView.setImageId(ResourceTable.Media_pic01);
            //设置拼图块的宽高,这里的参数单位为 vp,与 xml 文件中的统一
            swipeCaptchaView.setCaptchaWidth(30);	//单独设置宽度
            swipeCaptchaView.setCaptchaHeight(30);	//单独设置高度
            swipeCaptchaView.setCaptchaSize(30, 30);//设置宽高
            //设置判定的误差允许值
            swipeCaptchaView.setMatchDeviation(9f);
            //绘制一张新的验证码(这个方法在绑定控件时会自动调用,第一次不需要调用该方法生成验证码,用于重新生成验证码)
            swipeCaptchaView.createCaptcha();
        }
    }
    • RotateCaptchaView
    //MainAbilitySlice.java
    public class MainAbilitySlice extends AbilitySlice {
        RotateCaptchaView rotateCaptchaView;
        
        @Override
        public void onStart(Intent intent) {
            super.onStart(intent);
            super.setUIContent(ResourceTable.Layout_ability_main);
            
            //根据 id 找到相应的控件
            rotateCaptchaView = (RotateCaptchaView) findComponentById(ResourceTable.Id_rotateCaptchaView);
            //调用 setImageId 方法设置图片,如不设置图片,则会显示一张“暂无图片”内容的图片
            rotateCaptchaView.setImageId(ResourceTable.Media_pic02);
            //设置旋转块的半径,这里的参数单位为 vp,与 xml 文件中的统一
            rotateCaptchaView.setCaptchaRadius(80);
            //设置判定的误差允许角度
            rotateCaptchaView.setMatchDeviation(8f);
            //绘制一张新的验证码(这个方法在绑定控件时会自动调用,第一次不需要调用该方法生成验证码,用于重新生成验证码)
            rotateCaptchaView.createCaptcha();
        }
    }
  3. AbilitySlice.java 中处理回调函数

    //MainAbilitySlice.java
    swipeCaptchaView.setOnCaptchaMatchCallback(new SwipeCaptchaView.OnCaptchaMatchCallback() {
    	@Override
        public void matchSuccess(SwipeCaptchaView swipeCaptchaView) {
            //添加验证成功时的代码
        }
    
        @Override
        public void matchFailed(SwipeCaptchaView swipeCaptchaView) {
            //添加验证失败时的代码
        }
    });

    rotateCaptchaView同理
