無法動態添加TextInputLayout視圖

Question

我想基於用戶從微調器中選擇的項目填充TextInputLayouts。下面是我的XML（用 「CreatePollAnswer」 的ID是我要動態填充視圖）：

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

<LinearLayout 
    android:orientation="vertical" 
    android:padding="4dp" 
    android:layout_width="match_parent" 
    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:layout_height="wrap_content" 
      android:imeOptions="actionDone" 
      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:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      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:layout_height="wrap_content" 
      android:imeOptions="actionDone" 
      android:singleLine="true" 
      /> 
    </android.support.design.widget.TextInputLayout> 

</LinearLayout>

在AndroidManifest.xml文件添加應用程序標記內將以下代碼

android:theme="@style/Theme.AppCompat.Light"
