自定义编辑文本，侦听删除键不起作用

标签： android android-edittext

我目前正在使用一个自定义的EditText看起来像下面的图像，想法是总是开始写在左边，如果是空的，并按照你的方式从一个EditText跳到下一个，但我＆＃39 ;当我尝试回到上一个框时遇到问题，如果当前框是空的，那么android不会注册OnKeyListener事件，所以我不知道Backspace是否被按下了。

我尝试了很多像这样的https://github.com/GoodieBag/Pinview成功的PinView库，但他们没有提供字体支持，所以我不能像图像一样使用书法的自定义字体。

对此的任何帮助都将受到赞赏，也有任何关于如何整理这些混乱编码的想法。

Custom text edits

当前代码：

对于将来与这个人斗争的人，我找到了一种方法来保留库，然后在ViewGroup中找到每个EditText并以编程方式从那里设置属性

private void traverseEditTexts(ViewGroup v) {
    for (int i = 0; i < v.getChildCount(); i++) {
        Object child = v.getChildAt(i);
        if (child instanceof EditText) {
            EditText e = (EditText) child;
            e.setTypeface(TypefaceUtils.load(context.getAssets(), "fonts/RobotoMono-Bold.ttf"));
            e.setTextColor(getResources().getColor(R.color.pin_text_color));
            e.setPadding(8,4,8,4);
            e.setTextSize(32);
        }
    }
}
