下面是正常视图

景观

我想要实现的是在整个视图上有一个滚动视图，这样我就可以向下滚动以查看横向的所有视图。请注意，我使用的菜单抽屉布局是我的 XML 中的最后一个。如果尝试将滚动视图放在相对布局之前，我会收到以下错误

java.lang.IllegalArgumentException: DrawerLayout must be measured with MeasureSpec.EXACTLY.

如果我放在相对布局之后，它会午餐但不会滚动。

我已经能够解决滚动问题，但这就是我的抽屉的显示方式。截取我的主视图这是屏幕截图这是我的xml

请问有什么问题。

【问题讨论】：

您是否尝试将滚动视图包裹在“整个线性布局垂直开始标签”周围？
请浏览我的代码 @cYrixmorten 我是 android 新手，请告诉我在滚动视图之前放置线性布局的位置

标签： android

【解决方案1】：

您可以在<RelativeLayout..> 之后放置滚动视图。试试这个：

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

<ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_below="@+id/someid">

<RelativeLayout 
         xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools" 
         android:layout_width="match_parent"
         android:layout_height="match_parent">

    <!--  whole linearlayout vertical begin tag   -->

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="250dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:id="@+id/linearLayout">
        ...
    </LinearLayout>
</RelativeLayout>
</ScrollView>
</RelativeLayout>

【讨论】：

我经常这样尝试，我得到的错误是java.lang.IllegalStateException: ScrollView can host only one direct child
那是因为滚动视图只能包含一个孩子。您可以在<ScrollView> 之后再添加一个<RelativeLayout>，并在关闭</ScrollView> 之前将其关闭，以便所有内容都包含在<RelativeLayout> 中，它现在是<ScrollView> 的子代。
请检查我更新的代码..我不知道哪里错了，我的屏幕截图也是
对于 DrawerLayout 必须使用 MeasureSpec.EXACTLY 错误检查stackoverflow.com/questions/31746072/…
