Configure android EditText to allow decimals and negatives
You are just missing this in your EditText,
android:inputType="numberDecimal|numberSigned"
We can use,
edit_text.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED);if we need to use programmatically..
See this link may be it's help youhttp://developer.android.com/resources/articles/creating-input-method.html
and The possible values for the android:inputtype are:
•none•text•textCapCharacters•textCapWords•textCapSentences•textAutoCorrect•textAutoComplete•textMultiLine•textImeMultiLine•textNoSuggestions•textUri•textEmailAddress•textEmailSubject•textShortMessage•textLongMessage•textPersonName•textPostalAddress•textPassword•textVisiblePassword•textWebEditText•textFilter•textPhonetic•textWebEmailAddress•textWebPassword•number•numberSigned•numberDecimal•numberPassword•phone•datetime•date•time
