This bar appears when you arrow inputType as textPassword, but this will depend on the Android keyboard. If you want to use for an editText with visible text, you can use a textVisiblePassword.
<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/editText"
    android:hint="Search"
    android:inputType="textPassword" />
or
<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/editText"
    android:hint="Search"
    android:inputType="textVisiblePassword" />
							
Thank you, but I will continue to wait for other opinions or solutions, to see if anyone knows anything simpler than creating a custom keyboard...
