我的应用程序上有一个主页，里面有一个按钮。我已经实现了onClickListener。我想在单击按钮时更改为其他类。（使用不同的XML文件导航到应用程序中的另一个页面）我做错了什么？？
Intent myIntent = new Intent(this, menu_two.class);
startActivity(myIntent);
这是在switch语句中的代码中，该语句用于识别按下了哪个按钮。我使用的不是XML文件，而是直接从java硬编码的布局。
家我已经给了你足够的信息来帮助你
谢谢
首先，确保menu_two是一个活动。如果您没有使用XML，那应该不是问题。此外，请验证您是否已将menu_two添加到AndroidManifest.xml文件中，您必须在该文件中注册应用程序使用的所有活动。
