android自定义 数字键盘2

1.使用枚举定义键值和对应的类型。

2.输入框可以自定义。也可以使用自定义输入框

3.通过一个集合来完成输入数据的追加和移除

看过上一篇，知道上篇留了一个尾巴，只是说明了自定义数字键盘中使用技术，并没有贴相应的代码，这篇贴上代码，做出一些必要解释

public enum KeyboardEnum {

    one(ActionEnum.add, "1"),
    two(ActionEnum.add, "2"),
    three(ActionEnum.add, "3"),
    four(ActionEnum.add, "4"),
    five(ActionEnum.add, "5"),
    sex(ActionEnum.add, "6"),
    seven(ActionEnum.add, "7"),
    eight(ActionEnum.add, "8"),
    nine(ActionEnum.add, "9"),
    zero(ActionEnum.add, "0"),
    del(ActionEnum.delete, "del"),
    longdel(ActionEnum.longClick, "longclick"),
    cancel(ActionEnum.cancel, "cancel"),
    sure(ActionEnum.sure, "sure");

    public enum ActionEnum {
        add, delete, longClick, cancel, ActionEnum, sure
    }

    private ActionEnum type;
    private String value;

    private KeyboardEnum(ActionEnum type, String value) {
        this.type = type;
        this.value = value;
    }

    public ActionEnum getType() {
        return type;
    }

    public void setType(ActionEnum type) {
        this.type = type;
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }

}      

longClick, cancel, ActionEnum, sure

这些只是一些特殊处理，这里不进行扩展，会给出原文链接。其实也就是根据类型。做一些特殊处理罢了

这样看，就可以看出使用枚举类型的好处了。很清晰。数字0-9对应 追加。（字符串相加），删除操作，进行分开处理。

输入框使用的 GridPasswordView

​​​https://github.com/Jungerr/GridPasswordView​​

本来准备使用这个组件，不料和交互不符合。就作为一个输入框。他里面的事件，监听，能注释的都注视了。只是作为一个输入框使用

1.拿到资源，设置监听事件，处理onclick事件
