如何打开Android键盘仅显示Android中的自定义数字

Question

I want to show digits "0123456789/" on keyboard if open on click of SearchView but I don't know how it can be done. I am able to set InputType to a searchview like this

searchView.setInputType(InputType.TYPE_CLASS_NUMBER);

but not able to set custom digit to show on a keyboard .

from input type InputType.TYPE_CLASS_NUMBER numeric keyboard is opening but i also want to show "/" also with numeric digits 0123456789. I searched a lot on SO but didn't find any solution for this.

There is no easy solution for this. You have two options depending on what you can work with and what exactly you want.

1. If it is exactly as you say in your question, that is, to SHOW just the Characters that you specify, then the way to go about doing that would be to create a Custom SoftKeyboard . This will allow you to take only the desired inputs and will show only those characters that you have specified.
2. Otherwise you can disable taking other characters input (that are not to be available), by working with [onQueryTextChanged] 1 where you manipulate to resend only the values that you can take in as input. Here the default softKeyboard is used, but the input taken in by the SearchView are as per specification.

Note : my knowledge is mainly based on working with EditText rather than SearchView , so not able to provide exact codes for the above
