我所有其他onClick方法都起作用，除了那些我必须在布局中膨胀才能获得按钮的方法之外！我究竟做错了什么！这是一些代码：

这是我的xml文件：Main.xml：
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="@+id/tableLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">

<Button android:text="Level" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/level"></Button>
</TableLayout>
这是我的level.xml
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="@+id/tableLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">

</RadioGroup>
</TableRow>
<Button android:text="Set Level" android:id="@+id/updateLevel" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</TableLayout>
这是play.xml：

</TableLayout>
问题是您要添加的视图没有父视图，因此无法接收点击事件。目前，您正在使用扩大视图
View playv = inflater.inflate(R.layout.level, null);
您需要在第二个参数中放置一个父视图。
View playv = inflater.inflate(R.layout.level, parentView, false);
这将允许您使用父视图，但不能实际附加它。
