[英]Android - Graying out characters on keyboard?
I want to have an EditText element accept only 0's and 1's. 我想让一个EditText元素仅接受0和1。 I have specified its 'digits' attribute to:
我已将其“数字”属性指定为:
android:digits="01"
This allows for only 0 and 1 to be entered, but I want to know if there is a way to 'grey-out' all of the keyboard buttons except for 0 and 1? 这仅允许输入0和1,但是我想知道是否有一种方法可以“灰显”除0和1以外的所有键盘按钮?
