EditText中对于软键盘控制

1.BUG概述

    在猜数字游戏的开发中，对于EditText设置setEnable()的属性为false时，继续点击EditText继续出现软键盘，输入软件盘的字符，依然可以在EditText显示字符

2.解决方案

    在EditText中有一个setInputType()属性，里面参数为int 型。而InputType类中有如下常量：

       /**
     * Mask of bits that determine the overall class
     * of text being given.  Currently supported classes are:
     * {@link #TYPE_CLASS_TEXT}, {@link #TYPE_CLASS_NUMBER},
     * {@link #TYPE_CLASS_PHONE}, {@link #TYPE_CLASS_DATETIME}.
     * If the class is not one you
     * understand, assume {@link #TYPE_CLASS_TEXT} with NO variation
     * or flags.

    当设置InputType属性为TYPE_DATATIME_VARIATION_NORMAL时，点击EditText时将不会出现软键盘，若在软键盘已经跳出，那么软键盘输入的字符依然不可用。
