我正在开发一个Android应用程序，其中包含一个列表视图和每个项目的图片。ICS上的Android QuickContactBadge箭头
我在每幅图片上设置了一个QuickContact徽章。
在Android < ICS（机器人4）的图像被正确地显示，例如：
quick contact badge ok on android<4
但是一个Android ICS 4或高，箭头显示在右下方：
quickcontact badge arrow on ics
是否可以隐藏quickcontact徽章上的右下箭头？
这是不正确的，这是设计。 QuickContactBadge的目的不仅仅是显示一张图片，而且还提供一个界面来提供基于系统已知的现有联系人联系联系人的方法。 “箭头”在那里向用户表明，通过点击图片，他们可以获得更多的信息;它就像一个页面的弯曲角落。
如果您真的只想使用联系人的图片，我相信您需要使用ContactsContract API并自行收集数据。
http://developer.android.com/reference/android/provider/ContactsContract.html
这是可能的。使用此代码并将其作为QuickContactBadge导入，而不是导入android QuickContactBadge。
