在ScrollView中查看并不是全部

问题描述

我在ScrollView中有一个RelativeLayout.我的RelativeLayout的尺寸为android:layout_height="match_parent"，但视图的大小并不完整，就像wrap_content一样.

I have a RelativeLayout inside a ScrollView.My RelativeLayout has android:layout_height="match_parent" but the view doesn't take the entire size, it's like a wrap_content.

有没有办法实现真正​​的fill_parent/match_parent行为?

Is there a way to have the real fill_parent/match_parent behavior ?

我的布局:

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

    <ImageView
    android:id="@+id/top"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:scaleType="fitXY"
    android:src="@drawable/top" />

    <ImageView
    android:id="@+id/header"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/top"
    android:scaleType="fitXY"
    android:src="@drawable/headerbig" />

    <ImageView
    android:id="@+id/logo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/header"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="3dp"
    android:src="@drawable/logo" />

    <ScrollView
    android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/bottom"
    android:layout_below="@+id/logo"
    android:background="@drawable/background" >

        <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

             <ImageView
            android:id="@+id/dashboard01"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_above="@+id/dashboard02"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="30dp"
            android:src="@drawable/dashboard01"
            android:visibility="visible" />

            <ImageView
            android:id="@+id/dashboard02"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:layout_alignParentRight="true"
            android:layout_marginRight="10dp"
            android:src="@drawable/dashboard02" />

             <ImageView
            android:id="@+id/dashboard03"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/dashboard02"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="40dp"
            android:src="@drawable/dashboard03"
            android:visibility="visible" />
         </RelativeLayout>
    </ScrollView>

    <ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/logo"
    android:layout_centerHorizontal="true"
    android:scaleType="fitXY"
    android:src="@drawable/bar" />

    <ImageView
    android:id="@+id/bottom"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:scaleType="fitXY"
    android:src="@drawable/bottom" />

</RelativeLayout>
