您似乎已在 xml 布局中将您的 Button 定义为

     <button
       android:layout_width="fill_parent"
       ..........

                  />

但是你必须写一个大写b

     <Button
        android:layout_width="fill_parent"
         ............

                   />

这就是错误消息中的行所说的

    Caused by: android.view.InflateException: Binary XML file line #15: Error inflating class button  <--- You wrote button, but it has to be Button
