Question

我是Android新手。我的应用程序在真实设备上运行时正在关闭，但它在我的模拟器上工作正常。这是我在调试器上获得的错误代码。我正在尝试在pageViewer的帮助下添加图像滑块。在添加滑块之前，应用程序工作正常。

Answer 1

堆栈跟踪可能会产生误导。您的drawable可能有问题。尝试不同的@drawable，看看它是否有效。或者其他一个可能是你的图像文件大小有点大

您的错误是：

android.view.InflateException：二进制XML文件行＃0：二进制XML文件行＃0：错误导致类ImageView

Answer 2

我得到了答案。问题是，我的自定义布局的imageView源是mipmap，我已将其更改为drawable，现在正在运行。谢谢你的贡献。
