Prevent other language except English in EditText

Question

My android app has an EditText field where user can give input. But now i want user can\'t give input other (i.e Japanese, chain\'s) than English language.

Answer 1

you can limit the user to enter only specific characters in the edit text,

<EditText
    android:id="@+id/nameText"
    android:layout_width="177dp"
    android:layout_height="wrap_content"
    android:inputType="text"
    android:digits="abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ" />

By this, the user could only enter English words and space, nothing else..

Answer 2

You can add a TextWatcher that checks what the user is trying to enter (and reject what you don't want).

You cannot really check the language, though, but I guess you just want to limit the character set (to ASCII or maybe Latin-1).
