Dynamische Hinzufügen von TextInputLayout-Ansichten

Question

Ich möchte TextInputLayouts basierend auf dem Element auffüllen, das ein Benutzer aus einem Spinner auswählt. Unten ist mein XML (die ID mit "CreatePollAnswer" ist die Ansicht, die ich dynamisch auffüllen möchten):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/create_poll_linearlayout" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" 
tools:context="com.troychuinard.fanpolls.Fragment.CreateFragment"> 

<FrameLayout 
    android:background="@drawable/image_border" 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight=".525"> 

    <Button 
     android:id="@+id/add_image_button" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content"

     android:text="Click to Add Image" /> 
</FrameLayout> 

<LinearLayout

    android:layout_height="0dp" 
    android:layout_weight=".475"> 

    <android.support.design.widget.TextInputLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     > 
     <EditText 
      android:id="@+id/create_poll_question_editText" 
      android:layout_width="match_parent"

      android:singleLine="true" 
      android:hint="@string/create_poll_question" /> 
    </android.support.design.widget.TextInputLayout> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="horizontal"> 

     <TextView 
      android:id="@+id/how_many_answers_textView"

      android:text="@string/how_many_answers_text" 
      android:textColor="@color/black" 
      android:textSize="16sp" /> 

     <Spinner 
      android:id="@+id/number_of_answers_spinner" 
      android:layout_width="wrap_content" 
      android:layout_gravity="bottom" 
      android:layout_height="24dp" 
      android:background="@android:drawable/btn_dropdown" /> 

    </LinearLayout> 


    <android.support.design.widget.TextInputLayout 
     android:id="@+id/create_poll_answer" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     > 
     <EditText 
      android:id="@+id/create_poll_answer_editText" 
      android:layout_width="match_parent"

    </android.support.design.widget.TextInputLayout> 

</LinearLayout>
