Feature/add decimal pad to android (#19714)
Summary: For a current use-case we need the a keyboard with characters 0-9 and a decimal point (or comma depending on language settings) This exists on iOS as UIKeyboardType "decimalPad" and this is what react-native maps to for both "numeric" and "decimal-pad". This also exists on Android as inputType "numberDecimal", but is currently not accessible through react-native. This PR maps the value "decimal-pad" of the keyboardType property of TextInput to the Android inputType "numberDecimal", effectively making "decimal-pad" cross platform without breaking anything. * https://facebook.github.io/react-native/docs/textinput.html#keyboardtype * https://developer.apple.com/documentation/uikit/uikeyboardtype * https://developer.android.com/reference/android/widget/TextView#attr_android:inputType There is this bug in some Samsung keyboards where both the - sign and decimal sign disappear when the keyboardType is set to "number" and both the "signed" and "decimal" flags are set. (Like is the case when using the react-native keyboardType prop "numeric".) https://androidforums.com/threads/numeric-soft-keyboard-missing-minus-sign-in-android-8-0-samsung-a5.1272628/ For developers that need decimal numbers but not negative ones, using "decimal-pad" will provide a workaround. I reproduced this on a Samsung A5 only, but maybe other phones have this exact issue. #12988 #12977 #17473 #17474 * Added testcase consistent with existing keyboardType tests * Also added testcase for the related, but missing number-pad This PR follows the same approach as the recently merged PR introducing "number-pad" b638847 Documentation PR: facebook/react-native-website#405 [ANDROID] [ENHANCEMENT] [TextInput] - Added "decimal-pad" keyboard type Closes #19714 Differential Revision: D8429185 Pulled By: mdvacca fbshipit-source-id: 6b56da2088f2be427ebffa04c4e17c91ffb9f7d9
