Android 简单按钮事件不工作？

嗨，我想问一下，为什么我的按钮在点击时不起作用？我只是复制了我的其他版面按钮代码，并尝试自己创建，但仍然不起作用

<ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent">

<RelativeLayout

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/btnBeginner"
    android:layout_centerHorizontal="true"
    android:background="@drawable/learner_menu" />

<Button
    android:id="@+id/btnBeginner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/btnLearner"
    android:layout_alignParentTop="true"
    android:background="@drawable/beginner_menu" />

</RelativeLayout>

</ScrollView>

</LinearLayout>

试试这个：

<Button
    android:id="@+id/btnBeginner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/btnLearner"

将contentview设置到onCreate方法中

你到底想做什么？您从未设置内容视图。尝试一些来自互联网的安卓基础教程。当我点击它时，它有一个错误不像以前它什么都不做hahathanks和顺便说一句，我做了代码，但当我点击按钮时，它强制关闭，但比没有响应好hahaIt显示“安卓已停止工作意外强制关闭”但是当我试着把它放在第三个布局中时，会显示它工作得很好
