ScrollView不会在布局中滚动？

Question

我有这个顺序RelativeLayout / ScrollView / Relative Layout / Relative Layout，在最后的相对布局里面我有两个线性布局。

不知道为什么会这样。我对其他活动的布局几乎相同，并且它正在工作。

这是xml代码：

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android" 
    >
    <ScrollView 
        android:layout_width="match_parent"
        android:layout_height="4000dp"
        android:paddingBottom="5dp"
        android:paddingLeft="5dp"
        android:paddingRight="5dp"
        android:paddingTop="5dp"
        android:orientation="vertical"  
        android:scrollbars="none"  
        android:background="@drawable/url" >

        <RelativeLayout
            android:id="@+id/relativeLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

            <!-- Thumbnail Image -->

            <com.dusandimitrijevic.modification.TouchImageView
                android:id="@+id/thumbnail"
                android:layout_width="115dp"
                android:layout_height="180dp"

                android:layout_marginRight="8dp"
                android:src="@drawable/ic_horor_filmovi_ikonica" />

            <!-- Naslov Filma -->
            <TextView

Answer 1

我认为你的问题在这里 android：layout_height =“4000dp”。对于scrollView，您的内容不需要滚动，因为它不需要超过4000dp

尝试将其更改为match_parent

更新2

更改此

    <ScrollView                  
        xmlns:android="http://schemas.android.com/apk/res/android"  
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        android:orientation="vertical"  
        android:scrollbars="none">

        <RelativeLayout            
            android:id="@+id/relativeLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="@dimen/activity_vertical_margin"
            android:paddingLeft="@dimen/activity_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin"
            android:paddingTop="@dimen/activity_vertical_margin"
            android:background="@drawable/url">
