目前,我正在使用一个UITableView包含在其中的其他视图UIScrollView.我希望UITableView它的高度与其内容高度相同.
更复杂的是,我还插入/删除行以提供手风琴效果,这样当用户点击一行时,它将显示该行的更多细节.
我已完成插入/删除,但目前它没有更新UIScrollView,这是它的超级视图,以便UIScrollView重新计算内容大小,并且正确显示UITableView其中的其他视图UIScrollView.
我怎样才能实现这一点,以便UIScrollView在我更改内容时调整大小并正确布置其内容UITableView?我目前正在使用自动布局.
我需要在Android Studio + Robolectric中执行测试时运行调试.每次我试图通过选择运行它们debug的test从摇篮任务,我得到错误信息的任务:
运行package_name时出错:app_name [test]:无法打开调试器端口:java.net.SocketException"Socket closed"
有任何想法吗?
有人可以解释为什么这不会在R中单独打印所有数字
numberstring <- "0123456789"
for (number in numberstring) {
print(number)
}

字符串不是字符数组吗?什么方式在R中做到这一点?
