Question

我在这里是因为我有一个非常奇怪的错误，我正在使用QT，我正在尝试构建一个桌面和移动应用程序，现在用于Linux和Android Kitkat最低限度。

好吧，一切顺利，直到我将“rowDelegate”添加到我的TableView，在Linux上，完美的工作，在启动时与SIGSEV的Android崩溃。

可能我做错了什么，但我找不到我的错误。

这是“TableView”示例的一个版本，如果你为Android构建它，即使在模拟器中，应用程序也会在启动时崩溃。

我遇到了完全相同的问题。尽管你的帖子已经有一段时间了，但我在这里看不到解决方案。我使用qt5.7并导入QtQuick 2.4并导入QtQuick.Controls 1.4。我发现为崩溃周围的委托组件添加了一个显式高度。一定是个臭虫！

rowDelegate: 
    Rectangle {
        height: 30
        color: "blue" 
    }
