Question

我创建了一个具有标题和滚动正文的布局。我能够在纵向模式下看到标题，但是当它进入横向模式或者我必须滚动它时，标题丢失了。

我希望标题保持静态，只应滚动主体。左侧是纵向，右侧是横向。

main_activity.xml

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="@dimen/padding_screenEdge"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <include layout="@layout/header_inspection"/>

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <include layout="@layout/fragment_body"/>

    </ScrollView>
</LinearLayout>

fragment_body.xml

尝试将列包装在scrollview的一侧，并将标题保留在scrollview
之外

Answer 2

我发现了它的问题。显然，我应该将layout_height和layout_width纳入包含标记。因此， main_activity 的正确代码应为：

<强> main_body.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:tools="http://schemas.android.com/tools"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical"
              android:padding="@dimen/padding_screenEdge"
              tools:context="my.mimos.fssm.kpkt.layout.Lain2Generik">

    <include layout="@layout/header_inspection"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"/>

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <include layout="@layout/fragment_lain2_generik"/>

    </ScrollView>


</LinearLayout>

在横向/滚动视图中缺少视图
