Android 滚动视图不保持大小

我正在尝试制作一个带有标题、图像和滚动文本体的线性布局。出于某种原因，ScrollView似乎总是占据尽可能多的空间，因为它经常重叠标题和图像。我尝试过为每个对象指定权重，但它不会改变任何东西

这是我的线性布局

<LinearLayout android:id="@+id/gamedescriptionlayout"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:orientation="vertical"
          android:background="@drawable/backdrop9"
          android:visibility="visible"
          android:layout_marginBottom="20dp"
          android:layout_marginTop="20dp"
          android:layout_marginLeft="20dp"
          android:layout_marginRight="20dp"
          android:layout_gravity="center"> 

 <TextView android:id="@+id/DescHeader"
           android:layout_height="wrap_content"     
           android:layout_width="fill_parent"
           android:layout_marginBottom="10dp"
           android:layout_marginTop="10dp"
           android:layout_marginLeft="10dp"
           android:layout_marginRight="10dp"
           android:gravity="center_horizontal"
           android:textColor="#000000"
           android:text="Level 1" 
           android:textSize="25dp"
           android:layout_weight="1"/> 

 <ImageView android:id="@+id/DescImage"
            android:layout_height="wrap_content"     
            android:layout_width="fill_parent"
            android:layout_below="@id/DescHeader"
            android:gravity="center"
            android:src = "@drawable/wall"
            android:layout_weight="1"/>

 <ScrollView android:id="@+id/DescScroll"
             android:layout_height="wrap_content"     
             android:layout_width="fill_parent"
             android:layout_marginBottom="10dp"
             android:layout_marginTop="10dp"
             android:layout_marginLeft="10dp"
             android:layout_marginRight="10dp"
             android:layout_weight="1">

 <LinearLayout android:id="@+id/DescContainer"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content">   
 <TextView android:id="@+id/DescBody"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content" 
               android:textColor="#000000"
               android:text="HelloWorld LALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALA"/>
</LinearLayout> 
 </ScrollView>

</LinearLayout> 

我也尝试过将文本主体放在它自己的线性布局中（见上文），但没有任何限制

试试这个：

<LinearLayout android:id="@+id/gamedescriptionlayout"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:orientation="vertical"
          android:background="@drawable/backdrop9"
          android:visibility="visible"
          android:layout_marginBottom="20dp"
          android:layout_marginTop="20dp"
          android:layout_marginLeft="20dp"
          android:layout_marginRight="20dp"
          android:layout_gravity="center"> 

 <TextView android:id="@+id/DescHeader"
           android:layout_height="wrap_content"     
           android:layout_width="fill_parent"
           android:layout_marginBottom="10dp"
           android:layout_marginTop="10dp"
           android:layout_marginLeft="10dp"
           android:layout_marginRight="10dp"
           android:gravity="center_horizontal"
           android:textColor="#000000"
           android:text="Level 1" 
           android:textSize="25dp"
           android:layout_weight="0"/> 

 <ImageView android:id="@+id/DescImage"
            android:layout_height="wrap_content"     
            android:layout_width="fill_parent"
            android:layout_below="@id/DescHeader"
            android:gravity="center"
            android:src = "@drawable/wall"
            android:layout_weight="0"/>

 <ScrollView android:id="@+id/DescScroll"
             android:layout_height="0dp"     
             android:layout_width="fill_parent"
             android:layout_marginBottom="10dp"
             android:layout_marginTop="10dp"
             android:layout_marginLeft="10dp"
             android:layout_marginRight="10dp"
             android:layout_weight="1">

 <LinearLayout android:id="@+id/DescContainer"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content">   
 <TextView android:id="@+id/DescBody"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content" 
               android:textColor="#000000"
               android:text="HelloWorld LALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALALA"/>
</LinearLayout> 
 </ScrollView>

</LinearLayout> 

现在应该没事了

变化

android:layout_below="@id/DescHeader"

到

android:layout_below="@id/DescImage"
