问题 I created an InputFilter for an EditText component that only allows doubles within a range (e.g. from 1.5 to 5.5). Everything worked fine until I deleted the decimal point: I typed 1.68 and then deleted the decimal point. The value in the text field became 168, which is obviously outside the range.

Update: actually, this is not a problem with Asus Phones, it's a problem with Asus ZenUI's keyboard. You can install a keyboard you like to walk around the problem.

TextWatcher makes some text transofrmations (transliterates symbols from Russian into English). TextWatcher
