try this it will help you

change, instead of this line 

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

change like below

edit.setRawInputType(InputType.TYPE_CLASS_NUMBER |InputType.TYPE_NUMBER_FLAG_DECIMAL);

That's not what numeric does. Numeric is a hint to the keyboard that it should show a numberpad. It does not force the keyboard to do that, and it does not prevent other keys (like +, -, #, *, etc) from being shown or entered. If you want to prevent certain characters from being entered, you have to do that app side. If you want to do that, you need to set an InputFilter on the edit field.

Here's some code for that:

InputFilter filter = new InputFilter() { 
        public CharSequence filter(CharSequence source, int start, int end, 
Spanned dest, int dstart, int dend) { 
                for (int i = start; i < end; i++) { 
                        if (!Character.isDigit(source.charAt(i))) { 
                                return ""; 
                        } 
                } 
                return null; 
        } 
}; 
edit.setFilters(new InputFilter[]{filter});

Try to use TextView.setRawInputType(), the java equivalent of android:inputType
