有人可以告诉我为什么应用程序崩溃了吗？ 任何解决方案都会非常感激:)
答案 0 :(得分：3)
Caused by: java.lang.IllegalArgumentException: Binary XML file line #11: Must specify unique android:id, android:tag, or have a parent with an id for ai.wit.eval.wit_eval.MyActivity$PlaceholderFragment
例如，将andoid:id="@+id/something"添加到布局XML中的fragment元素。
后续问题：
Caused by: android.app.Fragment$InstantiationException: Unable to instantiate fragment ai.wit.eval.wit_eval.MyActivity$PlaceholderFragment: make sure class name exists, is public, and has an empty constructor that is public
您在布局XML中使用的包名称为ai.wit.eval.wit_eval，但在代码中您有com.wit。确保完整的类名一致。
