title: Two fragments stacked ontop of each other using transactional ADD - how to prevent edit text gaining focus on bottom fragment?
body: <p>Try stacking two fragments with editTexts on top of each other using an Add Transaction.   after that when you press the keyboard imeOption key next button the bottom fragment's edit text can gain focus. this is a security concern. user can type things into the bottom fragments edit text (blindly).  I tried the following code:</p>
  
  <pre><code>android:filterTouchesWhenObscured="true" 
  </code></pre>
  
  <p>but it has not helped at least on api 27.  </p>
  
  <p>my edit text itself looks like this, nothing special:</p>
  
  <pre><code>                                &lt;EditText
                                      android:id="@+id/et"
                                      android:layout_width="195dp"
                                      android:layout_height="wrap_content"
                                      android:layout_alignParentBottom="true"
                                      android:imeOptions="actionNone"
                                      android:layout_marginBottom="10dp"
                                      android:hint="@string/enter_name"
                                      android:filterTouchesWhenObscured="true"
                                      android:inputType="textNoSuggestions"
                                      android:textColorHint="#959595"
                                      android:textSize="11sp" /&gt;
  </code></pre>
  
  <p>the issue is very similar to <a href="https://stackoverflow.com/questions/22179773/android-tap-jacking-how-to-prevent-it">android tap jacking</a></p>
  
  <p>i tried even doing this:</p>
  
  <p>android:nextFocusDown="@+id/et_two" thinking it would bypass and go directly to the edittext i want. but instead the bottom edit text still gains focus.  </p>
