在我的应用程序中，我使用5个galleryview显示图像，正确完成，我可以正确填充图像。现在我想在每个图像下面添加textview。
我想要这样的画廊视图：
image1 Image2 Image3 image4
-------->Galleryview1
text1 text2 text3 text4
------------------------------------------
image1 image2 image3 image4
--------->Galleryview2
text1 text2 text3 text4
我的代码：

System.out.println("Inside cons");
getelement();
