Java 删除数字时应用程序崩溃（redmarobot输入掩码）

我正在使用卡号输入掩码。输入掩码工作正常，但当我尝试从输入中删除数字时，应用程序崩溃

这是我的密码

ArrayList<String> affineFormats = new ArrayList<>();     
        affineFormats.add("[0000] [000] [000] [000]");
        affineFormats.add("[0000] [000000] [00000]");
        affineFormats.add("[0000] [0000] [0000] [0000]");
          String format = "[0000] [000] [000] [000]";
        MaskedTextChangedListener listener = new MaskedTextChangedListener(
                format,
                affineFormats,
  AffinityCalculationStrategy.CAPACITY,
                true,
                etCardNumber,
                null,
                new MaskedTextChangedListener.ValueListener() {
                    @Override
                    public void onTextChanged(boolean b, String s, String s1) {
                   //here some code
                    }
                });
        etCardNumber.addTextChangedListener(listener);

请帮我解决这个问题。

嘿，你也可以粘贴你的崩溃日志吗？你没有把代码贴在注释行上，上面写着

//这里有一些代码。如果你没有，请编辑你的问题并粘贴。
