功能说明

  • 支持设置列数。
  • 支持设置行数。
  • 支持设置最少链接手势点个数。默认值为1。
  • 支持设置最大链接手势点个数。默认值为行*列。
  • 支持设置手势点样式。默认为线条格式,可设置为自定义图片。

  • 支持设置手势点样式为自定义图片时的 选中 状态图片。
  • 支持设置手势点样式为自定义图片时的为 错误 状态图片。
  • 支持设置手势路径显示消失模式。默认为手势结束时不显示已绘制路径。

使用说明

详情参考demo

主要接口

    //手势路径点重复模式
    public interface GestureRepeatMode {
        int DEFAULT = 0;//除相邻两个点不可重复外,其余每个点可重复多次。默认值。
        int NO_REPEAT = 1;//每个点单独不可重复。
    }

    //手势点样式
    public interface GestureStyle {
        int LINE = 0;//线条
        int IMAGE = 1;//图片
    }
    
    //当前状态
    public interface GestureState {
        int NORMAL = 0;//普通状态
        int ERROR = 1;//错误状态
    }

    //结束时手势显示模式
    public interface GestureDisappearMode {
        int APPEAR_ON_FINISH = 11;//手势结束时显示已绘制路径
        int DISAPPEAR_ON_FINISH = 12;//手势结束时不显示已绘制路径
        int APPEAR_ONLY_ERROR_ON_FINISH = 13;//仅当错误状态时,手势结束时显示已绘制路径
    }
    
    //手势点与路径绘制优先级
    public interface GestureDrawOrder {
        int SECTION_TOP = 0;//格子在上
        int LINE_TOP = 1;//线条在上
    }
    
    //结果监听
    public interface DetectedListener {
        int DETECT_SUCCESS = 0;//识别成功,手势点数正常
        int DETECT_LIMITED_MIN = 10;//识别失败,未达到手势点最小个数限制
        int DETECT_LIMITED_MAX = 11;//识别失败,超到手势点最大个数限制
        int DETECT_CANCEL = 20;//识别失败,意外取消

        /**
         * @param code            结果码
         * @param detectedGesture code为DETECT_SUCCESS时不为null,其他为null
         */
        void onDetectedGesture(int code, List<Section> detectedGesture);
    }

主要方法

  • 设置手势点图片样式时手势未选中时图片资源ID。
gestureView.setImageNormal(ResourceTable.Media_icon_zao_gesture_normal);
  • 设置手势点图片样式时手势未选中时图片。
gestureView.setImageNormal(PixelMapHolder imageNormal);
  • 设置手势点图片样式时手势选中时图片资源ID。
gestureView.setImageChecked(int resId);
  • 设置手势点图片样式时手势选中时图片。
gestureView.setImageChecked(PixelMapHolder imageChecked);
  • 设置手势点图片样式时手势错误时图片资源ID。
gestureView.setImageError(int resId);
  • 设置手势点图片样式时手势错误时图片。
gestureView.setImageError(PixelMapHolder imageError);
  • 设置手势点线条样式时未选中状态线条颜色。默认是Color.GREEN。
gestureView.setLineNormalColor(Color color);
  • 设置手势点线条样式时线条颜色。默认是Color.GREEN。
gestureView.setLineCheckedColor(Color color);
  • 设置手势控件错误状态时手势路径线条颜色。默认是Color.RED。
gestureView.setLineErrorColor(Color lineErrorColor)
  • 设置手势路径线条默认颜色。默认是Color.GREEN。
gestureView.setLineColor(Color color);
  • 设置手势点线条样式的线宽度。默认是4px。
gestureView.setLineWidthSection(float lineWidthSection);
  • 设置手势路径线的宽度。默认是4px。
gestureView.setLineWidth(float lineWidth);
  • 设置手势控件点阵行数
gestureView.setRow(int row);
  • 设置手势控件点阵列数
gestureView.setColumn(int column);
  • 设置连接点最少个数
gestureView.setMinGestureCount(int minGestureCount);
  • 设置连接点最大个数
gestureView.setMaxGestureCount(int maxCount);
  • 清空已选中手势数据
gestureView.clearGesture();
  • 根据手势点阵生成序列字符串。横向排列,起始0,顺序+1拼接成字符序列。
String string = GestureView.section2String(detectedGesture);
  • 判断是否是简单手势:转折点个数是否小于传入值。实际转折点比预期转折点小则为简单手势。反之,则为复杂手势。
boolean simpleGesture = GestureView.isSimpleGesture(detectedGesture, 1);
  • 设置手势绘制监听器
gestureView.setOnDetectedListener((code, detectedGesture) -> {
            //手势结束回调。
            if (code == GestureView.DetectedListener.DETECT_SUCCESS) {//绘制成功。
                String string = GestureView.section2String(detectedGesture);
                boolean simpleGesture = GestureView.isSimpleGesture(detectedGesture, 1);
                string = (simpleGesture ? "密码过于简单:" : "") + string;
                new ToastDialog(getAbility())
                        .setText(string)
                        .setAlignment(LayoutAlignment.CENTER)
                        .show();
            } else if (code == GestureView.DetectedListener.DETECT_LIMITED_MIN) {//手势点个数未达到设置的最小值。
                gestureView.setGestureState(GestureView.GestureState.ERROR);
                new ToastDialog(getAbility())
                        .setText("请连接最少" + gestureView.getMinGestureCount() + "个点")
                        .setAlignment(LayoutAlignment.CENTER)
                        .show();
            } else if (code == GestureView.DetectedListener.DETECT_LIMITED_MAX) {//手势点个数超到设置的最大值。
                gestureView.setGestureState(GestureView.GestureState.ERROR);
                new ToastDialog(getAbility())
                        .setText("请连接最多" + gestureView.getMaxGestureCount() + "个点")
                        .setAlignment(LayoutAlignment.CENTER)
                        .show();
            }
        });
