from layout add attribute

android:maxLength="1"

or from code

TextEdit te = findViewById(...);
te.setFilters( new InputFilter[] { new InputFilter.LengthFilter(1) } )

There is a maxLength attribute in EditText. Just set it to 1:

<EditText 
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:maxLength="1"/>
