android:imeOptions="actionDone" does not work

"actionDone" does not work

consider you want to have an EditText for taking only alpha numeric values as input. 

<android.support.v7.widget.AppCompatEditText
        android:id="@+id/newDeliverable"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginEnd="8dp"
        android:layout_marginStart="8dp"
        android:digits="1234567890 abcdefghijklmnopqrstuvwxyz"
        android:hint="@string/hint_add_new_deliverable"
        android:imeOptions="actionDone"
        android:inputType="text" />
 
 `android:digits` causes the issue 
 
 Solution: 
 you have to add android:singleLine attribute. 
 If we have android:digits attribute in EditText, then android:imeOptions will work when we add android:singleLine attribute.
 
 <android.support.v7.widget.AppCompatEditText
        android:id="@+id/newDeliverable"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginEnd="8dp"
        android:layout_marginStart="8dp"
        android:digits="1234567890 abcdefghijklmnopqrstuvwxyz"
        android:hint="@string/hint_add_new_deliverable"
        android:imeOptions="actionDone"
        android:inputType="text"
        android:singleLine="true" />
