Android QuickContactBadge стрелка на ICS
Я разрабатываю приложение для Android, содержащее представление списка с изображением для каждого элемента.
Я установил QuickContact значок на каждой картинке.
На андроиде значок быстрого контакта в порядке на Android<4 Но у Android ICS 4 или выше, справа внизу появляется стрелка: быстрый контакт стрелка на ics Можно ли скрыть эту нижнюю правую стрелку на значке быстрого контакта?

Эта стрелка называется оверлеем и для Lollipop, а над простейшим способом скрыть следующее:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
contactBadge.setOverlay(null);
}
Для поддержки pre-Lollipop я расширяю QuickContactBadge:
/**
* Extend the QuickContactBadge to hide the overlay.
*/
public class MyQuickContactBadge extends QuickContactBadge {
private static final String OVERLAY_FIELD_NAME = "mOverlay";
public MyQuickContactBadge(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public MyQuickContactBadge(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyQuickContactBadge(Context context) {
super(context);
init();
}
private void init() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
super.setOverlay(null);
return;
}
try {
// Pre-lollipop we use reflection to null the overlay drawable
Field overlayField = QuickContactBadge.class.getDeclaredField(OVERLAY_FIELD_NAME);
// setAccessible(true) prevents IllegalAccessException
overlayField.setAccessible(true);
overlayField.set(this, null);
} catch (NoSuchFieldException | IllegalAccessException e) {
// TODO: log exception
}
}
}
Это возможно. Вместо импорта андроидов QuickContactBadge используйте этот код и импортируйте его как QuickContactBadge.

Это не неправильно, и это по замыслу. Целью QuickContactBadge является не только отображение изображения, но также предоставление интерфейса для вызова методов контакта с контактом на основе существующего контакта, известного системе. "Стрелка" предназначена для указания пользователю, что, нажав на картинку, они могут получить больше информации; это как загнутый угол страницы.
Если вы действительно хотите использовать только изображение контакта, я полагаю, что вам нужно будет использовать API ContactsContract и собирать данные самостоятельно.
