Pattern Locker

此为Android App中常用控件之一的图案解锁(手势解锁、手势密码、九宫格密码、九宫格图形锁等)控件开源库,PatternLockerView为主控件,负责图案密码的设置和验证,PatternIndicatorView为指示器辅助控件,可根据设计需要选择使用。

由于本人水平有限,如果您在使用的过程中发现bug,或者发现有更好的实现方式和代码中写得不足的地方,请提issue或者PR,本人万分感激!!!

功能介绍

  • 支持自定义各状态下(未操作时、操作时以及操作出错时)线颜色、填充色和线宽;
  • 支持自定义各种状态下(未操作时、操作时以及操作出错时)每个CellView样式和连接线样式;
  • 支持设置图案绘制完成后延迟自动清除的时长(默认1秒);
  • 支持是否跳过中间点(默认不跳过);
  • 支持是否触碰震动反馈(默认不震动);
  • 支持指示器辅助控件可选择使用;
  • 业务逻辑(至少连点几个点、验证时最多可出错几次等)须自定义。

基本用法

第一步: 首先打开项目根目录下的 build.gradle,添加jitpack仓库地址,代码如下:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

第二步: 打开需要依赖此 library 的module,比如此demo中是 app 这个 module,添加:

dependencies {
    ....
    implementation 'com.github.ihsg:PatternLocker:2.5.4'
}

第三步: 在布局文件中添加PatternLockViewer和PatternIndicatorView(可根据设计需要选择使用)控件,示意如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorWhite"
    android:orientation="vertical">        
    
    ......    
    
    <com.github.ihsg.patternlocker.PatternIndicatorView
        android:id="@+id/pattern_indicator_view"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_gravity="center"
        android:layout_margin="20dp" />

    <com.github.ihsg.patternlocker.PatternLockerView
        android:id="@+id/pattern_lock_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="50dp"
        android:layout_marginRight="50dp"
        android:layout_marginTop="20dp" />
</LinearLayout>

第四步: 在java代码中为PatternLockerView添加OnPatternChangeListener并处理相应业务逻辑,

patternLockerView.setOnPatternChangedListener(object : OnPatternChangeListener {
            override fun onStart(view: PatternLockerView) {
                //根据需要添加业务逻辑
            }

            override fun onChange(view: PatternLockerView, hitIndexList: List<Int>) {
                //根据需要添加业务逻辑
            }

            override fun onComplete(view: PatternLockerView, hitIndexList: List<Int>) {
                //根据需要添加业务逻辑
            }

            override fun onClear(view: PatternLockerView) {
                //根据需要添加业务逻辑
            }
        })

OnPatternChangeListener接口说明如下:

interface OnPatternChangeListener {
    /**
     * 开始绘制图案时(即手指按下触碰到绘画区域时)会调用该方法
     *
     * @param view
     */
    fun onStart(view: PatternLockerView)

    /**
     * 图案绘制改变时(即手指在绘画区域移动时)会调用该方法,请注意只有 @param hitList改变了才会触发此方法
     *
     * @param view
     * @param hitIndexList
     */
    fun onChange(view: PatternLockerView, hitIndexList: List<Int>)

    /**
     * 图案绘制完成时(即手指抬起离开绘画区域时)会调用该方法
     *
     * @param view
     * @param hitIndexList
     */
    fun onComplete(view: PatternLockerView, hitIndexList: List<Int>)

    /**
     * 已绘制的图案被清除时会调用该方法
     *
     * @param view
     */
    fun onClear(view: PatternLockerView)
}

常用方法说明

1. PatternLockerView

// 监听器
setOnPatternChangedListener(listener: OnPatternChangeListener?)

// 设置当前绘制的是否是错误图案
updateStatus(isError: Boolean)

// 清除已绘制的图案
clearHitState()

2. PatternIndicatorView

// 设置已绘制图案及状态
updateState(hitIndexList: List<Int>?, isError: Boolean)

已知问题解决方案

1. Java开发使用该库出现的错误: Didn't find class "kotlin.reflect.KProperty"

解决方案:请配置kotlin开发环境 参考Kotlin官网

步骤1: 在根目录下的buid.gradle

buildscript {
    ext {
        kotlinVersion = '1.3.40'
    }
    dependencies {
        ......
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"
        
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

步骤2: 在module目录下的buid.gradle

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

dependencies {
    ......
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlinVersion"
}

自由定制

1. 默认样式简单定制

可以通过xml和kotlin代码两种方式更改默认颜色、绘制时颜色、出错时颜色、填充色以及连接线粗细等

推荐使用xml方式,更精简,更方便

1.1 xml方式

  • PatternLockerView可设置的属性
属性名 说明 默认值
plv_color 默认图案的颜色 #2196F3
plv_hitColor 绘制图案的颜色 #3F51B5
plv_errorColor 绘制图案出错时的颜色 #F44336
plv_fillColor 图案填充色 #FFFFFF
plv_lineWidth 图案的线宽 1dp
plv_enableAutoClean 自动清除绘制图案 true
plv_enableSkip 是否跳过中间点 false
plv_enableHapticFeedback 是否使用触碰震动反馈 false
plv_freezeDuration 操作完延迟自动清除时长(单位ms) 1000

示例如下:

<com.github.ihsg.patternlocker.PatternLockerView
        android:id="@+id/patternLockerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="50dp"
        android:layout_marginTop="20dp"
        android:layout_marginRight="50dp"
        app:plv_enableSkip="true"
        app:plv_color="@color/color_gray"
        app:plv_enableAutoClean="false"
        app:plv_errorColor="@color/color_red"
        app:plv_fillColor="@color/colorWhite"
        app:plv_hitColor="@color/colorPrimary"
        app:plv_freezeDuration="5000"
        app:plv_lineWidth="3dp" />
  • PatternIndicatorView可设置的属性
属性名 说明 默认值
piv_color 指示器默认图案的颜色 #2196F3
piv_hitColor 指示器中选中图案的颜色 #3F51B5
piv_errorColor 指示器中选中图案出错时的颜色 #F44336
piv_fillColor 图案填充色 #FFFFFF
piv_lineWidth 图案的线宽 1dp

示例如下:

<com.github.ihsg.patternlocker.PatternLockerView
        android:id="@+id/patternLockerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="50dp"
        android:layout_marginTop="20dp"
        android:layout_marginRight="50dp"
        app:plv_enableSkip="true"
        app:plv_enableHapticFeedback="true"
        app:plv_color="@color/color_gray"
        app:plv_enableAutoClean="false"
        app:plv_errorColor="@color/color_red"
        app:plv_fillColor="@color/colorWhite"
        app:plv_hitColor="@color/colorPrimary"
        app:plv_lineWidth="3dp" />

1.2 kotlin代码方式

这里styleDecorator可以通过normalCellView、hitCellView和linkedLineView三者均可获取,下面以normalCellView为例。

  • PatternLockerView可设置的属性
val plvStyle = (this.patternLockerView.normalCellView as DefaultLockerNormalCellView).styleDecorator

plvStyle.normalColor = ContextCompat.getColor(this, R.color.colorWhite)
plvStyle.fillColor = ContextCompat.getColor(this, R.color.color_blue)
plvStyle.hitColor = ContextCompat.getColor(this, R.color.colorPrimaryDark)
plvStyle.errorColor = ContextCompat.getColor(this, R.color.color_red)
plvStyle.lineWidth = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 5f,
                resources.displayMetrics)
  • PatternIndicatorView可设置的属性
val pivStyle = (this.patternIndicatorView.normalCellView as DefaultLockerNormalCellView).styleDecorator
        
pivStyle.normalColor = ContextCompat.getColor(this, R.color.colorWhite)
pivStyle.fillColor = ContextCompat.getColor(this, R.color.color_blue)
pivStyle.hitColor = ContextCompat.getColor(this, R.color.colorPrimaryDark)
pivStyle.errorColor = ContextCompat.getColor(this, R.color.color_red)
pivStyle.lineWidth = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 2f,
                resources.displayMetrics)

2. 深度定制

PatternLockerView和PatternIndicatorView均提供了设置连接线、各个小单元控件在不同状态下(正常、设置以及出错)的绘制方式的方法,只需要实现如下几个接口即可,从而可以根据设计需求高度自由定制。

  • 正常状态下各个小单元控件的样式(PatternLockerView和PatternIndicatorView通用)
interface INormalCellView {
    /**
     * 绘制正常情况下(即未设置的)每个图案的样式
     *
     * @param canvas
     * @param cellBean the target cell view
     */
    fun draw(canvas: Canvas, cellBean: CellBean)
}
  • 设置时各个小单元控件的样式(PatternLockerView和PatternIndicatorView通用)
interface IHitCellView {
    /**
     * 绘制已设置的每个图案的样式
     *
     * @param canvas
     * @param cellBean
     * @param isError
     */
    fun draw(canvas: Canvas, cellBean: CellBean, isError: Boolean)
}
  • PatternLockerView连接线的样式
interface ILockerLinkedLineView {
    /**
     * 绘制图案密码连接线
     *
     * @param canvas
     * @param hitIndexList
     * @param cellBeanList
     * @param endX
     * @param endY
     * @param isError
     */
    fun draw(canvas: Canvas,
             hitIndexList: List<Int>,
             cellBeanList: List<CellBean>,
             endX: Float,
             endY: Float,
             isError: Boolean)
}
  • PatternIndicatorView连接线的样式
interface IIndicatorLinkedLineView {
    /**
     * 绘制指示器连接线
     *
     * @param canvas
     * @param hitIndexList
     * @param cellBeanList
     * @param isError
     */
    fun draw(canvas: Canvas,
             hitIndexList: List<Int>,
             cellBeanList: List<CellBean>,
             isError: Boolean)
}

分别设置主控件和指示器的定制实现:

// 主控件
patternLockerView.normalCellView = ... //定制实现
patternLockerView.hitCellView = ... //定制实现
patternLockerView.linkedLineView = ... //定制实现

// 指示器控件
patternIndicatorView.normalCellView = ... //定制实现
patternIndicatorView.hitCellView = ... //定制实现
patternIndicatorView.linkedLineView = ... //定制实现

温馨提示:更详细的定制方式可参考Library中default开头的代码。
