java - Android - 将 fragment 添加到 xml 布局时出错

Question

我正在尝试将 fragment 添加到对话框 fragment 的 xml 布局中，但它不起作用，当我尝试打开对话框 fragment 时，应用程序崩溃，因为该 fragment 包含在布局中

下面是xml布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

 <fragment
         android:id="@+id/flContent"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:padding = "10dp"
         class="com.OptimusApps.stayhealthy.AndroidXMLParsingActivity" />

</LinearLayout>

这是我的 logcat

看起来您的应用程序中还有另一个名为 flContent 的 id，请尝试更改 id 名称。
