Fehler Set TextInputLayout in Fragment

Question

Ich habe ein Problem mit TextInputLayout, wenn ich die Fehlermeldung festlegen. Ich verwende das folgende Paket 'com.android.support:design:23.1.1' in einem Fragment. Dies ist der Code

if (tvName.getText().toString().trim().isEmpty()) { 
     textInputLayoutName.setErrorEnabled(true); 
     textInputLayoutName.setError("erreur"); 
    } 

der XML Teil

 <android.support.design.widget.TextInputLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:theme="@style/TextLabel" 
      android:id="@+id/input_layout_name"> 
      <EditText 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:id="@+id/name" 
       android:hint="@string/name"/> 
     </android.support.design.widget.TextInputLayout> 

Der Stil

<style name="TextLabel" parent="TextAppearance.AppCompat"> 
    <item name="android:textColorHint">@android:color/darker_gray</item> 
    <item name="android:textSize">20sp</item> 
    <item name="colorAccent">@color/colorPrimary</item> 
    <item name="colorControlNormal">#2E7D32</item> 
    <item name="colorControlActivated">#1B5E20</item> 
</style> 

und hier der Fehler

Answer 1

Da Sie ein Layout Thematisierung sollten Sie nicht abgeleitet von TextAppearance. Leiten Sie es stattdessen von ThemeOverlay ab. Zum Beispiel:

<style name="TextLabel" parent="ThemeOverlay.AppCompat.Light"> 
    <item name="android:textColorHint">@android:color/darker_gray</item> 
    <item name="android:textSize">20sp</item> 
    <item name="colorAccent">@color/colorPrimary</item> 
    <item name="colorControlNormal">#2E7D32</item> 
    <item name="colorControlActivated">#1B5E20</item> 
</style>
