Добавить эффект пульсации в listview

Question

Я пытаюсь добавить эффект пульсации в MvxListView, но его не происходит. Вот макет.

     </LinearLayout> 
    </LinearLayout> 
</LinearLayout> 

Я попытался андроид: listSelector = "@ вытяжка/list_selector" и андроида: drawSelectorOnTop = "истина", но эффект не показывает вверх. В списке нет ничего другого.

Вот list_selector:

<?xml version="1.0" encoding="utf-8"?> 
<ripple xmlns:android="http://schemas.android.com/apk/res/android" 
    android:color="@color/lg_pressed_state"> 
    <item android:drawable="@color/purple_bw"/> 
</ripple> 

Спасибо заранее.

Answer 1

Я завершаю достижение этой обертывания макета элемента внутри LinearLayout и добавил к нему пульсацию.

Пожалуйста, попробуйте и дайте мне знать:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/ripple_effect" 
    android:orientation="vertical"> 

    <RelativeLayout xmlns:app="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/rltContent" 
     android:background="@color/youBackground" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

     <!-- Your content here --> 

    </RelativeLayout> 
</LinearLayout> 

Ripple пример:

<ripple xmlns:android="http://schemas.android.com/apk/res/android" android:color="@color/colorPrimaryDark"> 
    <item android:drawable="@color/colorPrimary" /> 
</ripple> 

Answer 2

Я всегда имел успех при установке android:background="?selectableItemBackground" к элементу списка и добавление слушателя OnClick (без слушателя, там при нажатии на элемент не пульсировала).

Возможно, это также работает, установив этот фон на весь список или в стиле; в противном случае вам нужно будет создать отдельный файл макета для элемента списка.
