Как использовать SwitchCompat?

Question

У меня есть ActionBarActivity. В нем я создаю список, используя ListView и ArrayAdapter. В ней я пытаюсь использовать SwitchCompat:

<android.support.v7.widget.SwitchCompat 
    android:id="@+id/sampleSwitch" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentTop="true" 
    android:layout_marginTop="20dp" 
    android:gravity="right" 
    android:paddingRight="10dp" 
    android:textOff="OFF" 
    android:textOn="ON" 
    android:text="" 
    android:clickable="true" 
    android:checked="true" /> 

Но что-то пошло не так ...

Это мое приложение Тема:

<style name="AppTheme" parent="Theme.AppCompat.Light"> 
    <item name="colorPrimary">@color/primary</item> 
    <item name="colorPrimaryDark">@color/primary_dark</item> 
    <item name="colorAccent">@color/accent</item> 

    <item name="android:textColorPrimary">@color/white</item> 
    <item name="android:windowBackground">@color/windowBackGroung</item> 

    <item name="android:navigationBarColor">@color/black</item> 
</style> 

и моя зависимость:

dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 
compile 'com.android.support:appcompat-v7:21.0.+' 
compile 'com.android.support:cardview-v7:21.0.+' 
compile 'com.android.support:recyclerview-v7:21.0.+'} 

У меня нет действия на SwitchCompat в моем java-коде. Пожалуйста, покажи мне мою ошибку.

Answer 1

найти решение. Я не могу использовать <android.support.v7.widget.SwitchCompat в xml. Мне нужно создать его программно.

ContextThemeWrapper ctw = new ContextThemeWrapper(getApplicationContext(), R.style.AppTheme); 
SwitchCompat sc = new SwitchCompat(ctw); 
LinearLayout linearLayout = (LinearLayout) rowView.findViewById(R.id.linearLayoutLightsItem); 
linearLayout.addView(sc);
