Android - How to disable certain keys in virtual keyboard
提问by henrywibowo
How to disable certain keys (say number/symbol keys) in Android virtual keyboard?
如何禁用 Android 虚拟键盘中的某些键（比如数字/符号键）？
Specifically I want user can't input a double quote ( " ) character when virtual keyboard is showed up when user focus on a standard android EditText widget.
具体来说，当用户专注于标准的 android EditText 小部件时，我希望用户不能在虚拟键盘出现时输入双引号 (") 字符。

You can't, sorry. After all, the input method editor may not have "keys" in the first place.
你不能，对不起。毕竟，输入法编辑器可能一开始就没有“键”。

Then you will have to block the input at the EditText, by means of an InputFilter, as is described here: How do I use InputFilter to limit characters in an EditText in Android?
然后，你将有权阻止在输入EditText，通过的手段InputFilter，因为这里描述：如何使用输入过滤器来限制字符一个EditText在Android中？
