提前致谢

Answer 1

首先来自您的错误日志

android.view.InflateException： 二进制 XML 文件行 #2： 错误 充气类(

似乎您对约束布局有某种问题。 但是您已经正确包含库，以及正确提及XML中的约束布局。

所以这个代码可能有一个问题。

android:background="@drawable/mahadev_imagesbg"

在运行时，Android 会根据需要(基于屏幕尺寸和分辨率(调整图像大小。它使用位图在内部调整大小。这是非常 内存密集型 .所以您的设备红米2(红米2(有内存问题，它正在生成错误。

因此，请尝试一种解决方案：将此(mahadev_imagesbg(图像复制到drawable-ldpi，mdpi，hdpi文件夹，然后使用该设备再次测试。 或者尝试使用较低分辨率的图像。 也许它会解决您的问题。
