研究一直没有结果，因为所有其他对该错误的引用似乎都可以可靠地重复；我无法始终重复此错误：

正如我上面所说，这个错误并不是一直发生的。它似乎发生了大约（但不完全是）2-3次，然后2-3次运行没有问题。
这是我的资源文件：

这是我的java。请注意，我什至尝试为我的 ViewTarget 硬编码宽度和高度，但仍然出现不一致的错误。我还尝试在我的资源文件中创建占位符 TextViews，但仍然不行。

我很确定这是android绘制对象方式的一些时间问题，但我不知道为什么它们在某些运行中正确绘制但在其他运行中不正确。
除非您确定已在其他地方就间歇性问题提出过问题，否则请不要回答这个问题 :-)
