我的小应用程序运行良好。当我使用ScrollView时，它会覆盖我的应用程序的标题栏JustJava。

你是否尝试过这样：
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_height="match_parent"
android:layout_width="match_parent"
tools:context=".MainActivity"
app:layout_behavior="@string/appbar_scrolling_view_behavior" >
或添加android:layout_below="+@id/toolbar"或类似android:layout_below="+@id/appbarlayout"
