How to set an InputType to display negative float number for an inputTypeEditText

Question

I need to display negative and positive values inside an TextInputEditText. I am setting the inputType programatically:

inputTypeEditText.setInputType(InputType.TYPE_CLASS_NUMBER | 
InputType.TYPE_NUMBER_FLAG_DECIMAL);

the above code works for positive float numbers only.

And also I tried

inputTypeEditText.setInputType(InputType.TYPE_CLASS_NUMBER | 
InputType.TYPE_NUMBER_FLAG_SIGNED);

but this keyboard is similar with the text keyboard and shows to much characters.

Answer 1

I made the float keyboard which displays float positive and negative numbers using the following code:

inputTypeEditText.setInputType(InputType.TYPE_NUMBER_FLAG_SIGNED|
           InputType.TYPE_CLASS_NUMBER|InputType.TYPE_NUMBER_FLAG_DECIMAL);
