你能详细说明一下，你想达到什么目的吗？在Menu.java中，几乎没有cardview。单击cardview后，它将被定向到File1.java。基本上，在我点击File1.java中的submit按钮后，我想禁用Menu.java中的cardview并更改颜色。如果（disableCard）{cardView1.setEnabled（false）；cardView1.setClickable（false）；Log.d（标记“此处代码也成功！”）；}那么即使禁用了CardView，您仍然可以单击它？是的。仍然可以单击CardViewokey，尝试更新的答案，如果仍然不起作用，请发布Menu.java文件的完整代码。
