我正在开发一个 Android 应用程序，其中包含一个列表视图，每个项目都有一张图片。
我QuickContact在每张照片上都设置了一个徽章。
在 android < ICS (android 4) 上图片正确显示，例如：
但是Android ICS 4 或更高，右下角出现一个箭头：
是否可以在快速联系徽章上隐藏此右下箭头？

此箭头称为叠加层，对于 Lollipop 和上方，以下是隐藏它的最简单方法：
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
contactBadge.setOverlay(null);
}
为了支持棒棒糖之前的版本，我扩展了 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
}
}
}

有可能的。不要导入机器人 QuickContactBadge，而是使用此代码并将其作为 QuickContactBadge 导入。

这不是错误的，这是设计使然。QuickContactBadge 的目的不仅仅是显示图片，还提供一个界面，根据系统已知的现有联系人调出联系联系人的方法。“箭头”用于向用户表明，通过点击图片，他们可以获得更多信息；它就像一页的弯角。
如果您真的只想使用联系人的图片，我相信您将需要使用 ContactsContract API 并自己收集数据。
