请找到 xml 文件代码和活动代码。当我打开应用程序时，我看不到任何选项卡。请帮助我。像上面一样，我有 4 个这样的标签要显示，但它们都没有显示

改变你的框架布局

<FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_above="@+id/tabs" />

使用 android:layout_above="@android:id/tabs"
