安卓中ScrollView里面的布局不能撑满整个ScrollView

我有个布局,

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/red">

    <RelativeLayout
            android:layout_width="match_parent"
            android:background="@color/black"
            android:layout_height="match_parent">


        <ImageView
                android:id="@+id/Ic_background"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:src="@mipmap/ic_background" />


        <EditText
                android:id="@+id/PasswordEdit"
                android:layout_width="match_parent"
                android:layout_height="@dimen/x50"
                android:layout_below="@+id/Ic_background"
                android:layout_margin="@dimen/x10"
                android:background="@drawable/password_back"
                android:hint="密码"
                android:inputType="textPassword"
                android:padding="@dimen/x10"
                android:textColor="@color/black"
                android:textColorHint="@color/dimgray"
                android:textSize="@dimen/x20" />

        <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_below="@+id/PasswordEdit"
                android:layout_margin="@dimen/x10"
                android:orientation="horizontal">

            <Button
                    android:id="@+id/OnbackBton"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:background="@mipmap/button"
                    android:paddingLeft="@dimen/x35"
                    android:paddingTop="@dimen/x10"
                    android:paddingRight="@dimen/x35"
                    android:paddingBottom="@dimen/x10"
                    android:text="返回"
                    android:textColor="@color/white"
                    android:textSize="@dimen/x15" />

            <View
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:layout_weight="1" />

            <Button
                    android:id="@+id/SubmitBton"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:background="@mipmap/button"
                    android:paddingLeft="@dimen/x35"
                    android:paddingTop="@dimen/x10"
                    android:paddingRight="@dimen/x35"
                    android:paddingBottom="@dimen/x10"
                    android:text="确认"
                    android:textColor="@color/white"
                    android:textSize="@dimen/x15" />
        </LinearLayout>

        <com.sunchip.vendingmachine.view.BottomStatusBarView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true" />
    </RelativeLayout>
</ScrollView>

 

看内容,ScrollView里面的RelativeLayout的布局应该是满的,但是实际上,底部的那个自定义view,没有占满底部的位置,如:

一看就没满屏,解决方案====================

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true">

 在ScrollView的布局加上这句话 :android:fillViewport="true" 就能解决
