当我在Nexus 5上运行此代码时，它在启动时崩溃，我不知道为什么。

以下是预览窗口的屏幕截图：

我已经尝试了Project＆gt;清理并重启了eclipse几次，但到目前为止还没有帮助

我已经遗漏了25个与我发布的相同的其他ImageView，除了数量不断增加。但我确信这些都是正确的。任何建议将不胜感激

这有助于解释什么吗？

2 个答案:

答案 0 :(得分：0)

听起来您的图片已损坏。从drawable文件夹中删除它并将其替换为新文件夹。

之前我有过类似的问题。这是由于图像文件损坏。我不知道为什么android报告找不到ImageView类，我也没有想过挖掘源代码来查找它，但这对我来说是什么。
