前言:

最近因工作需要,自己撸了一个计算器Dialog,这边拿出来跟大家分享下,写的不好,请多指教
PS:知识点来不及写了,注释也没时间加,大家先看着,后续有时间再补上

先看效果图:

自己做的第一个GIF

}

Activity上调用方式:

    /**
     * 显示利率计算器
     */
    private void showOperationDialog() {
        CalculatorFinancialDialog dialog = new CalculatorFinancialDialog(getActivity());
        dialog.show();
    }
