After using RequestFocus(), EditText field behaves as disabled

I have an EditText field where a user enters an inventory location. If the location isn't valid, the error description appears (i.e. "Location not found"), after which the user must press the field again to try another location.

I have an EditText field where a user enters an inventory location. If the location isn't valid, the error description appears (i.e. "Location not found"), after which the user must press the field again to try another location.

I'm trying to use RequestFocus() so that the user doesn't need to press again before entering another location. It appears to work. The EditText field becomes underlined and the cursor blinks at its beginning, but nothing can be typed. It's as if the field is disabled, but debug shows it both enabled and HasFocus. It is, in fact, the only EditText enabled.

 <EditText
    p1:layout_width="150dp"
    p1:layout_height="33dp"
    p1:layout_below="@id/spnrAreas"
    p1:id="@+id/etxtLocation"
    p1:layout_toRightOf="@id/lblLocation"
    p1:textColor="@color/Black"
    p1:inputType="textCapCharacters"
    p1:nextFocusDown="@+id/etxtItem" />
                   {txtErrorMessage.Text = "Location not found";
                    etxtLocation.Text = "";
                    etxtLocation.RequestFocus(); 
                    return; }

Is there a method other than RequestFocus() that would make the program behave as if the EditText (etxtLocation) were pressed?
