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..
