请帮我解决这个问题
答案 0 :(得分：0)
下面：
ft.replace(R.layout.activity_main, orderedItemListFragment);
目前将布局文件ID作为第一个参数传递，但替换方法所需的布局容器id R.id.container_body。
传递布局ID，其中想要用作片段容器，如：
ft.replace(R.id.container_body, orderedItemListFragment);
答案 1 :(得分：0)
问题是android无法在其活动container_body的布局中找到布局容器activity_public_barcode_scanner。因此它显示了类似的错误No view found for id 0x7f0e0079
ft.replace(R.id.container_body, orderedItemListFragment);
确保container_body中有activity_public_barcode_scanner。
答案 2 :(得分：0)
缺少替换片段的ID。 activity_public_barcode_scanner是打开PublicBarcodeScannerActivity类的主要布局。您可以通过替换布局ID而不是新布局来打开新的片段
ft.replace(R.layout.activity_main, orderedItemListFragment);
错了。
