在setGridViewItemClickListener中获取错误，以及如何显示可绘制图像 [英] Getting error in setGridViewItemClickListener and also how can show images from drawable

问题描述

我使用GridView和ViewPager创建了具有14个图像的图像(如画廊或小书)的android应用 正在显示URL中的所有图像.我还想要帮助如何显示可绘制的图像

I have created android app using GridView with ViewPager for images like gallery or small book which have 14 images am showing all image from URL. i want also help that how can show my image from drawable

GridView成功打开，我能够启动该应用程序.

GridView got open successfully and i am able to launch the application.

功能也可以正常工作，但是当我想从GridView中打开单个图像时，我的应用程序将关闭并显示该应用程序已停止并再次打开应用程序的消息.

Functionality is also working fine but when I want to open single image from GridView then my app close and showing message that app has stopped and open app again.

请查看我的代码并指导我如何解决此问题.这是我的代码:
